Y50 - Linux thread

I did not have any problems with it. Let me help you with the Nvidia Card.

If you look at Nvidia drivers, the latest version for Nvidia Geforce 860M is 340.58

How To Install The NVIDIA 340.24 Driver On Ubuntu 14.04, Ubuntu 13.10, Ubuntu 12.04 And Derivative Systems | LinuxG.net

Just Follow those steps, when you are done, reboot the laptop.

Open Nvidia settings (if you wanna use terminal type "/usr/bin/nvidia-settings"). There you will see all the settings when it is using Nvidia card. There you would see the version (340.58)

If you only see 2 (Application profiles, Nvidia settings configuration), then Nvidia drivers have not being activated. When that is the case, open "Software-properties-gtk". Go to "Additional Drivers"-->Click first on "Nouveau Display driver", then click back on "Nvidia Binary Driver" and then click on "Apply changes". Reboot your laptop to be sure of it. When you have done that, open Nvidia settings again and look if you see all the settings. When that is the case, you will also have a setting called "Prime Profiles". I would advise you to really use it when you are not really doing something on your laptop that uses a lot of GPU power. This saves a lot of battery


Let me know if you succeeded. PS, DO NOT INSTALL "Intel Graphic Drivers". If i'm not wrong they are already being shipped in to the kernel it self.

 

I have the Y50-70 of this laptop.

If fully charged, using only LAN cable for connectivity and brightness around 70% i can get 2-3 hours when it would completely turn off by it self.

 

I'm not sure what you mean, but the battery goes for like 2-3 hours, the Laptop does a splendid job running games on Linux Ubuntu (tried Tropica 5, Deadfall adventures, CS Global Offensive) using Nvidia GeForce GTX 860M (Maxwell).

 

I installed Touchpad indicator
How To Install Touchpad Indicator 1.0.2 On Ubuntu 14.04 Trusty Tahr | LinuxG.net

When you get in to the settings of this applications you can configure multitouch. I installed it so it would disable when connecting a mouse.

 

I had the same problem, but when i installed Touchpad indicator, to disable the touchpad when a mouse is connected, it solved the problem. FN+F6 is working fine right now.

I had a question of my self to you guys. Guys, how do you flash to the latest bios using Linux.

My current bios version is 1.09 and the latest is 1.14.

I have already installed freedos etc. But im not sure what kind of files to use.

Laptops and netbooks :: Lenovo Y Series laptops :: Y50 70 Notebook Lenovo - Lenovo Support (NL)

 

Should I do this after a fresh install? Also, does this work on 14.10?

 

Thank you very much. That would help much.

 

A fresh install is always +1 if you ask me. That makes sure that no other settings have been configured other then default settings. I was planning at first to install 14.10, but after looking at software that i always install, most of those did not yet have a *.deb version for 14.10. So i decided to stick with 14.04.

My advice if you haven't installed 14.10, is to stick with 14.04 because it's a LTS version. If you do already have installed 14.10, then i guess there would be no reason that it wouldn't work. The PPA also supports Utopic Unicorn (Ubuntu 14.10).

 

OOh guys, i forgot to mention something. This laptop has no default "fn" buttons to for example to go to the next/previous/pause/play track if you are listening music or even mute the sound. I found a excellent solution for this.


For this install CompizConfig settings manager. Use the option "commands". Use the "command line" fields.

For example when you wanna add key binding mute/unmute button,

Code:

amixer -D pulse sset Master toggle

Then you can bind a way to toggle mute/unmute the volume. I used a "key binding". The place you put the command in, if it was "command line 0", then at the "key bindings"-tab use "Run Command 0". I clicked "Grab key combination" and used "CTRL+0" all the way next to --> button.

 

I have been using the FHD model for over a month now. And I loved it.

The only thing that I feel lacking in the Linux environment for this laptop is it's subwoofer. It came with Windows 8 and Lenovo Smart Audio, but in Linux I am unable to take proper output from it's JBL I would really like some help here.

The sound is good but not like I have in Windows, and believe me it feels amazing being on the dark side(while running Windows )

If any of you know how to make this work I would be more than thankful.

 

Hi firangistan,

I have been searching on the web about the sound that you have experienced on Windows 8. It is kind of hard for me to know what you are talking about, because the minute i bought my laptop, i instantly removed Win8 and put Linux Ubuntu on it.

As far as i have come with information about the dolby digital surround sound system v2 and of course the subwoofer, it seems it does not support Linux. The sound is already amazing to me, but i guess it can get even better. I have experimented with ALSA and Pulse audio and all kind of different audio/video players.

I found out that the sound of "gnome-mplayer" is amazing.
"VLC" has a dolby surround option.
Audacity had if you ask me the best sound output of them all.

Other players i used were SMPlayer (front-end Mplayer) and Totem.

I did not find any linux versions of Lenovo Smart Audio.

 

Hello guys, I am new user of y50. I am quite happy with it but I have troubles with running nvidia on linux mint(as all of us). Should i use bumblebee with nvidia-331 or should i download 340 as you describe here in some posts?
sudo apt-get install nvidia-331 would be really easy but is not version 331 too old? This terms are not so clear for me!

Thank you for any help!

 

Haha I was also going to do that same but I wanted to play games hassle free so I decided to keep it and believe me this sound thing is so annoying that one day I almost shifted to Windows. I listen to music most of the time and once you experience this beast in Windows, you never want to come back

VLC and 'gnome-mplayer' are okay-ish. I've tried tweaking settings but couldn't get it on spot.

I have also tried searching here and there. Tried installing custom audio drivers from somewhere which resulted in no audio at all.

I am back to the initial driver configuration xD

Please reply if you find anything regarding this thing. I'll also post if I get a driver.

 

Read my previous comments. There you will find the answer. Last night i got an update from 340.58 to to nvidia 340.65. I updated to it and also no problems.

My advise would be to use Nvidia instead of bumblebee. Why? Well if the drivers are from Nvidia it self, they are still better then alternative solutions. In the past when there was no solution to use both GPU's Bumblebee was back then an excellent alternatieve, but now that is a thing of the past.

 

Hahaha, well if i do listen to music, i can only use earpieces when i am at school and at home i have 5.1 dolby digital surround sound system, so no need to use the audio of the laptop. But i do agree with you with whatever external solution one has, still we need to fix the audio problem of the laptop. Although linux/ubuntu is not at fault because the vendor refuses to create software for it. If i do find a solution i will post it here.

 

Interestingly, mine lacks the 1920x1080 mode by default. I had to add it manually.
More disappointingly, the performance improvement between running 3840x2160 and 1280x720 (3x less in each axis) is at best limited. That leads me to wonder if maybe optimus/bumblebee is rendering in full 3840x2160 and scaling down or something along those lines. And then there's that quite visible rippling around the middle of the screen when running on optimus. Still, 25-30fps on Borderlands 2 on Optimus is still better than 5fps on the Intel GPU.

I have to say this surprised me. I thought the 4GB 860M was based on the older 1152 core Kepler, and it was only the 2GB 860Ms that were based on the 640 core GM107 chip, but lspci and cuda-z do in fact confirm that these indeed have a 4GB GM107 640 core version. In a way, that makes the battery life on these even more disappointing, and explains the somewhat lacking gaming performance.

I'm going to hazard a guess you don't actually have a Y50. You cannot use just the Nvidia card. The display panel and the HDMI port are wired to the Intel GPU. You can disable the Nvidia GPU in the BIOS but not the Intel chip. Intel chip is the only thing that can do the mode setting. There are one or two laptops that provide a full switching option where you can disble the Intel GPU, but they are an exception rather than the norm. The way Optimus works is by making the Nvidia GPU do the rendering off screen (on a headless Xorg) and then passing it back to the Intel's frame buffer. Current bumblebee implementation does this using VirtualGL. This is not entirely overhead-free, but it works reasonably well and without a massive performance hit.

Also note that you CANNOT just install the nvidia binary driver from Nvidia. Special care needs to be taken to not clobber the system's Mesa libGL with the Nvidia version. The Nvidia version must be kept separate and only used when optirun is invoked. This is because VirtualGL (what is used to get the rednered frames from the Nvidia frame buffer to the Intel frame buffer) uses the Mesa libGL, and accelerated Nvidia rendering requires Nvidia's libGL.

It is perhaps worth noting that this is not at all dissimilar to how ESX VSGA virtualization works. ESX runs headless Xorgs and uses them for rendering. It captures the frame buffer contents, compresses them into H264 and pipes them out over the network. On Kepler and Maxwell GPUs it also leverages NVENC for hardware compression (separate codec core, not running using the shader cores). Of course, compression is irrelevant in the Optimus case (but it may be useful to you if you want to build your own Nvidia driver package using the latest 346.x beta for use with patched ffmpeg for transcoding videos).

 

I would be kind of strange to make an account on a forum i never visit and start making "claims' if i did not have a Y50 =_=!. My model is the Lenovo Ideapad Y50-70 0045NL search it up on google.. and i already said it in one of my previous posts.

About what i said of switching between GPU. I am not sure what they call it.. but here a printscreen of it.

 

Do you happen to know what the name of the binary is and what package it is a part of?
I'm pretty sure that what this does is set environment variables so that the applictions started following the switch are either run using optirun or without. Switcing to the Nvidia card in this way won't disable the Intel chip since this will still be proxying everything to the screen. This is bog standard Optimus setup, not a magical way to make the Nvidia GPU wired straight to the display, bypassing the Intel GPU.

On a totally unrelated note, I have just tested ffmpeg with NVENC patches and the Y50 is capable of transcoding 1080p H.264 at 130-140fps with the slow profile. It is necessary to invoke ffmpeg using optirun or it won't see the nvidia GPU. That's fairly impressive and as expected approximately double the throughput of Kepler modules.

 

I used it from xorg-edgers

So I did end up buying the Y50-70 1TB/8GB sshd, and I'm about to install Ubuntu 14.04. So I'l be resizing my windows partition as you said, from Disk Manager, and set aside 150 GB for Ubuntu. Now, when you talk about installing grub to dev/sda.... what exactly do you mean? Isn't that the Windows installation area? How's the dual boot working for you? Did you have to make changes to UEFI boot to Legacy and all that? Are there any other pearls of wisdom you may have for me? My laptop s barely a day old and I really don't want to mess up....

 

dev/sda is not the windows partition. iirc, every hard drive has a little spot in the front where the bootloader gets written. Think it was called the MBR, though i could be wrong.

The last time I installed ubuntu on a uefi laptop, I used this guide: Guide To Install Ubuntu 14.04 In Dual Boot Mode With Windows 8 Or 8.1 UEFI

 

andy, I installed the nvidia drivers by downloading the .run file from the nvidia website, I changed to runlevel 2 ctrl-alt-F2 and I killed gdm(I use ubuntu gnome) and then I went through the install. I rebooted and black screen. I have no idea how to uninstall the driver from there. I want to try again, but since I had just installed ubuntu gnome, 14.04.1, I just stuck my live usb back in and wiped it and reinstalled.

How can I remove this driver if I try that again?

 

OK, so as I just posted, I tried downloading the .run file from nvidia and that caused hell, I'd still like to know how to undo that just in case I run intop a similar issue.

As for right now, I plan to try the ppa and install that way with nvidia-340. I'm hoping that will work and easier to uninstall for me.

I just got the Y50 4K yesterday and I installed Ubuntu Gnome 14.04.1.

I also noticed a few other issues that maybe folks here who have the 4k model may have fixes for.

1. chrome on my 4k screen is not usable. The address bar is soooooo tiny, I need a loupe to read it. sign of awesome resolution though.
2. when I connect my 27" 1080 monitor, the res on that monitor is horrid. I tried using the xrandr command here, but I get an issue with mouse constraints and using the panning option with --panning 1920x1080 or --panning 3840x2160 causes even worse issues.
xrandr --output eDP1 --auto --output HDMI1 --auto --scale 2x2 --right-of eDP1
3. randomly (I haven't found the cause yet) my screen resolution will just go wrong and I lose mouse and keyboard input. I'll look for better details, but want to know if anyone else has the same issue.

I have the 256SSD and I was seeing 2 hours battery life on the intel video card.

Question: Should we really be using the optimus drivers at all? It is my understanding that switchable and optimus are two separate nvidia technologies and my laptop has switchable.

Question 2: Has anyone tried installing VMWare workstation on their Y50? When I was in the bios, I noticed that intel virtualization was shut off and I turned it on. Anyone see an issue with that?

Question 3: Am I the only person who has ubuntu gnome on a Y50? Wouldn't mind finding someone who could give me some tips. Anyone running Gnome on a different dist would be good too.

Note: Can I update the bios without making a windows live usb and installing it that way? (such a PITA)


========================update==========================
So I tried installing the nvidia-340 from the ppa listed. Here is the fun that I ?endured?

Good news is that the nvidia drivers saw both intel integrated graphics and the nvidia graphics so I'm guessing that this will somehow be possible to configure.

1. The screens switched places and the secondary monitor now had the top and bottom bars
2. I tried running nvidia settings application in order to change the settings
2a. application loaded on 4k monitor with 4k resolution, and would not allow mouse or keyboard back on the other monitor.
3. nvidia settings crashed when I selected 'detect monitors' -repeatedly -even after reboots
4. monitors were showing as a single monitor 'X Server'
5. tried editing xorg.conf to add a second monitor, but not too familiar so it failed probably because of my own fault

There were a lot of issues, these were the ones that made it completely unusable. I uninstalled so need a new option. Ideas? will bumblebee or another autobot help? These so called drivers sound more like decepticons to me.

 

I tried this on my old laptop. After 3 straight days of trying to get it to work(yes I used the same guide as you) I ended up trying to commit suicide with a childrens pumpkin carving knife. I broke down and now only use legacy, but I don't dual boot to windows so I'm probably a bit troubled anyway. This is my work laptop btw.

 

Last time I fooled around with the drivers from Nvidia's site, if I reran the .run file it offered to uninstall the drivers. I think it also offered to fix Xorg.conf. (IIRC.) Much easier to install from a PPM or normal repo if at all possible, but not all driver versions are available that way.

Apologies if this is a stupid question, but when you couldn't move your mouse off one monitor, did you try going the opposite direction? Had that happen to me. OBTW, I also "had fun" with left vs. right and two monitors with the additional fun of running Win 8.1 in a different PC and connecting all with a KVM. I'm not sure I got it all right and it made my head hurt. Good luck!

 

Hank, I finally found how to uninstall them and the .run file needs to be run with a --uninstall switch. As for fixing xorg.conf, the drivers do delete this file since UbuntuGnome doesn't create it out of the box.

I tried installing from ppa, both nvidia-340 and nvidia-343. Both gave the same result.

Yes, when I was unable to move the mouse or use keyboard on second monitor, I did try repeatedly on all four corners.

I've been playing around with the command below, but I seem to be having issues with the mouse being restricted to the top left quarter of my HMDI1/external monitor. Not a permanent fix, but if I can get the mouse to work, this would be nice until I get the driver to work.

xrandr --output eDP1 --auto --output HDMI1 --auto --scale 2x2 --right-of eDP1

I've tried using a --panning switch but it gives me a whole slew of other issues and requires a hard reboot.

 

Answer - Question 1: I am using the Optimus driver only. I have not problems with my Graphic Card.
Answer - Question 2: I had installed in the past Vmware workstation instead of Virtualbox. The result, i got back to Virtualbox. Why? The problem with Vmware is, that it sucks up almost all the power of your computer to function greatly. What i mean by that is that Ubuntu is getting slow because Vmware is asking very big priority for its own. Virtualbox is more pleasant in use because you can switch very easily between virtualmachine and Ubuntu. I think that Vmware is designed specifically for servers and not really for a desktop/laptop. About the the Intel virtualization, if you want to install Virtualmachine on your laptop, then i would advise you to turn it on. Intel Virtualization gives you the possibility to lend the Virtualmachine couple of your CPU cores. I give my Virtualmachine 4 CPU cores. It works very nice. I have the virtualmachine with Win7 put on classic looks and only installed software that i would need. Like Winrar, Symantec endpoint protection, MS Office, Ultraiso, Adobe acrobat reader pro, CCleaner, MalwareBytes.

Answer - Question 3: I am not sure what you mean by Ubuntu gnome. I my self use Gnome-Ubuntu-fallback. That is the old (gnome2) interface. About tips, i am not sure what tips you would be looking for. Compiz settings?

Answer note: I have tried it with Linux, i did not succeed. That is exactly my same question. I hate to even touch Windows. Always giving me more problems then solution no matter what hardware i use.

About the Nvidia drivers. I am not sure what is going on. If you open "displays", there you can see what you are doing.

 

I will have to give optimus a try then. I was trying to figure out if optimus would be a problem since the Y50 doesn't use NVIDIA optimus, but instead switchable. Trying to figure out when bumblebee and optimus would be useful. Anyone tried them besides shingeri? My next try this afternoon will be optimus.

shingeri, that is quite a list on windows 7. Why not use 7zip instead of winrar? It works with more formats and is free and I've seen less bugs that winrar. Also, the windows antivirus, used to be defender, is pretty decent. those malware softwares bog down the system. I just take daily backups and if I get infected, I step back a version. We have to use vmware, but I'll try virtualbox.

#3 UbtuntuGnome is a distribution. It's backed by ubuntu, but it's for people who think unity is ugly and don't want to install gnome themselves. ubuntugnome.org I don't like compiz, takes too much memory which I cannot spare until I get the video drivers working correctly. Tips, just little things that people have noticed using this distro. I've only had it loaded on this laptop for three days so I am really hoping that if people know of other issues like this one, they would let me know.

Note: I have a usb with windows xp black on it, maybe I can get that to work. Or I can figure something out with soemthing else. I actually forgot to ask if anyone updated their bios bto the latest and if so, does it let you choose the video card or just switchable vs uma?

So today is optimus, I will let you know if that works.

 

So I tried a few more things yesterday. One required a reformat since I could not figure out how to resolve it. Here is a list.

1. I installed Optimus, I restarted and the settings>details still showed the intel haswell mobile graphics. Uninstalled as I could not find information as to how to load Gnome with Optimus.
2. Installed latest NVIDIA drivers from the website. They installed and I was unable to load into the gnome desktop. I tried uninstalling these drivers with the NVIDIA*.run --uninstall. It uninstalled, but still would not load gnome. I was in a time crunch so I reformatted to run on a clean system
3. I decided that I need to follow the route of installing the drivers from ppa, then one by one deal with the issues that arise from it. I still need to figure out how I can xrandr scale 2x2 my second monitor without the mouse constraints.

 

This is a double message.

 

What i am wondering is, when you install the drivers using the PPA. Which drivers do you install? Because to be sure, i have not installed the beta-drivers of Nvidia only the stable ones (Nvidia 3.40). When installing these drivers does it it work afterwards? Or are you getting some issues? Because if i read your comment it sounds the issues you are having is with the second screen using HDMI cable.

I am kind of confused right now. Nvidia-optimus is the functionality by switching between Integrated GPU and the Nvidia GPU right?

My current situation is exactly how it is decribed in the next url. Just switching between GPU and logout-login to take the effect.

How to install and configure Nvidia Optimus driver on Ubuntu - Xmodulo

Btw, which Nvidia card do you have in your laptop? The GeForce GTX 860M right? The most recent version of stable Nvidia drivers are the 340.65 for the GeForce GTX 860M.

 

I have installed two sets of drivers from the ppa. 340 and 343. When I do this, a number of things happen which I will just have to deal with one by one. First, the monitors switch which one is monitor 1 meaning the taskbars switch to the second monitor. The resolution of the 1080 goes down even further and in one test I lost the ability to use the mouse or keyboard on the 1080 monitor. It was not successful, but I may
be able to go through each item one by one to resolve things. There is nothing wrong with the HDMI cable. I've been using this one for two months fine on my old win laptop.

Yesterday I upgraded to gnome-shell 3.12.2, we will see if gnome will play better with the drivers now.

I tried optimus. I would try to switch video cards in the nvidia settings manager and it would always go back to the intel haswell card. It would not switch to the nvidia card ever no matter what. I may try bumblebee or the other autobot driver. I'll try again with the steps on that link for optimus, but looks like the steps that I took.

I do have the 860M and I have been using the 340 from the ppa. I only tried 343 once and saw no difference to 340.

I also had another issue that would resolve my resolution problem if fixed, but I had to open a bug report with ubuntugnome and they are working with me on it.

=============update==============
I tried the 331 and 340 drivers with the nvidia-settings and nvidia-prime. It properly installed the drivers and when I rebooted, I was unable to use my mouse on my monitor and it only showed a desktop on my hmdi monitor and not my laptop's built in monitor. So that won't work. Going to go back to ubuntu-gnome bug report and see if those guys can help.

 

Hope you fixed up your system, I tried installing Nvidia drivers just once I've got Ubuntu running on Y50 but I wasn't even able to login into Gnome.
I had to a new clean install for get again the system working..
Right now I'm running Ubuntu internal GPU, I'm so scared trying to install again Nvidia drivers since I've set up all the environment and don't want to do that again:\ hopefully somebody comes out a step by step guide.

Do you guys notice that colors are way too darker? I tried looking in colors settings but I'm anable to calibrate the monitor even if I've installed necessary packages/dependecies


Today I was curious to hear the subwoofer but I think that it doesn't work! Right now I've added this line in '/etc/modprobe.d/alsa-base.conf', let's see if it works!

Code:

options snd-hda-intel model=auto

 

Thanks, and no. I have not gotten the video card to work. I stopped trying for now because this is my daily use workstation and I cannot keep formatting and starting over. I'm glad to see someone else with my issue.

I am not sure if the sub works on mine since I use headphones all the time. I will look at you code and try adding it to the config file.

Too bad nvidia won't support their own driver. Kind of a pain in the not being able to get help from the maker of the driver at all.

Loving the laptop with Linux on it.

I am wondering if anyone has seen issues with running VMware on top of Linux on this laptop? I'm seeing the VM lock up for a few seconds. I think that it's a video card issue with two machines trying to use the crappy Intel video card. Virtual box works fine.

 

I've seen this happening on my dekstop (running a GTX 970). I haven't figured out what is happening that doesn't let you into gnome after installing the drivers but, at least for me, for some weird reason it only affects the session from which you installed the drivers. If you have another one (like guest) you can still log into gnome and the nvidia control panel will show everything is installed and working properly. I seriously doubt that's the case but I haven't had the chance to try any games on it.


Edit: Question about a clean install. Can I just wipe every partition in the SSD and install both Windows and Ubuntu again or is there something important in the recovery/factory partitions that I should not lose?.

 

Your issue with 4k resolution...i think it has been fixed now. With the stable 3.46 drivers for Linux.
http://www.phoronix.com/scan.php?page=news_item&px=NVIDIA-346.35-Linux-Driver
http://www.geforce.com/drivers

Code:

Release Highlights
Added support for the following GPUs:
GeForce 800A
GeForce 800M
GeForce GTX 970M
GeForce GTX 980M
Added support for X.Org xserver ABI 19 (xorg-server 1.17).
Improved compatibility with recent Linux kernels.
Fixed a bug that prevented internal 4K panels on some laptops from being driven at a sufficient bandwidth to support their native resolutions.
Fixed a regression that prevented the NVIDIA kernel module from loading in some virtualized environments such as Amazon Web Services.
Fixed a regression that caused displays to be detected incorrectly on some notebook systems.
Fixed a bug that could cause X to freeze when using Base Mosaic.
Fixed a regression that prevented the NVIDIA X driver from recognizing Base Mosaic layouts generated by the nvidia-settings control panel.
Updated the NVIDIA X driver to reject frame packed interlaced HDMI 3D modes during mode validation. These modes were being validated by the driver, despite never having been supported.
Fixed a bug that prevented the console from being restored after forcefully terminating X, on some GPUs with multiple DisplayPort monitors attached. This bug also subsequently prevented X from being started following the failed console restoration.
Updated the version of libvdpau shipped with the driver to 0.9.  This version honors the VDPAU_DRIVER_PATH environment variable and fixes a race condition if multiple threads call VdpDeviceCreateX11 simultaneously. See
http://lists.freedesktop.org/archives/vdpau/2014-December/000274.html for more information.

Please note that users are encouraged to use their distribution's libvdpau packages rather than relying on the one shipped with the NVIDIA graphics driver.

Fixed a bug that caused the ACPI hotkey mask to be set incorrectly on some laptops even when the EnableACPIHotkeys option is disabled.
Disabled the EnableACPIHotkeys option by default.  This option is now considered deprecated and will be removed in a future driver release. On modern Linux systems, display change hotkey events are delivered to the desktop environment as key press events, and the desktop environment handles the display change by issuing requests through the X Resize and Rotate extension (RandR).
Fixed a bug that caused the screen image to be shifted when screen transformations (such as rotations or reflections) were enabled on a G-SYNC display attached to a Kepler-based GPU.
Fixed a bug that caused a blank screen when setting a mode requiring YUV 4:2:0 compression. These modes are not currently supported.
Fixed a bug that caused an incorrect DisplayPort link configuration to be displayed after a hotplug or unplug.
Added support for decoding VP8 video streams using the NVCUVID API on GPUs with VP8 hardware decode support.
Added support for the following EGL extensions:
EGL_EXT_device_base
EGL_EXT_platform_device
EGL_EXT_output_base
Added the ability to increase the operating voltage on certain GeForce GPUs in the GeForce GTX 400 series and later. Voltage adjustments are done at the user's own risk. See the documentation on the "CoolBits" X configuration option in the README for details.
Added support for NVENC on GeForce GPUs. For more details on the NVENC SDK, see: https://developer.nvidia.com/nvidia-video-codec-sdk.
Removed a sanity check in nvidia-installer that tested the availability of POSIX shared memory. The NVIDIA GPU driver has not required POSIX shared memory since release 270.xx.
Removed the NVIDIA Unified Memory kernel module, nvidia-uvm.ko, from the driver package on 32-bit architectures.
Added accelerated support for r8g8b8a8, r8g8b8x8, b8g8r8a8 and b8g8r8x8 RENDER formats.
Updated nvidia-settings to take advantage of GTK+ 3, when available. This is implemented by building the nvidia-settings user interface into separate shared libraries (libnvidia-gtk2.so, libnvidia-gtk3.so), and loading the correct one at run-time.
Added the nvidia-settings option --gtk-library to allow specifying the path of the directory containing the user interface library or the path and filename of the specific library to use.
Added support in nvidia-settings for a GTK+ 3 user interface on x86 and x86_64.
Added the nvidia-settings option --use-gtk2 to force the use of the GTK+ 2 UI library.
Updated nvidia-installer to install a file in the system's xorg.conf.d directory, when a sufficiently new X server is detected, to cause the X server to load the "nvidia" X driver automatically if it is started after the NVIDIA kernel module is loaded.
This feature is supported in X.Org xserver 1.16 and higher when running on Linux 3.9 or higher with CONFIG_DRM enabled.

Improved the performance of nvidia-installer by enabling the use of parallel make when building the NVIDIA kernel modules. The concurrency level can be set with the --concurrency-level option, and defaults to the number of detected CPUs.
Updated nvidia-installer to determine default installation locations for libraries based on the presence of known paths in the ldconfig(8) cache and the filesystem, rather than hardcoded distro-specific paths.
Fixed a GLSL compiler bug that would produce corruption when running games such as Far Cry 3 in Wine.
Fixed the EGL_KHR_stream_cross_process_fd extension.
Fixed rendering corruption that sometimes happened when calling DrawElementsInstancedBaseVertexBaseInstance(), DrawElementsInstancedBaseInstance(), or DrawArraysInstancedBaseInstance().
Dramatically improved OpenGL Framebuffer Object creation performance.
Removed the limit on the maximum number of OpenGL Framebuffer Objects.
Updated the NVIDIA OpenGL driver to prefer $XDG_CACHE_HOME over $HOME as the default location for storing the GL shader disk cache.

Well i THINK, that there is a recovery/factory partition to easily recover windows. I my self am not a big fan of Windows. I had Windows hardly 5 minutes on the laptop when i bought it, then removed everything. From my knowledge, i don't think that the recovery is that important. I mean if you do make a clean install and remove all the crap that was installed by default, you would not be able to use the recovery of it. I my self have never used recovery on any computer when fixing a computer/laptop with Windows. If you were searching for drivers and other software for this laptop, then i would advice you to download them from Lenovo support page of this laptop.

Usually many laptop vendors install a bunch of crap that you are not and will not ever use, they only make your laptop slow. If you would do it with a clean install, you will have a bigger chance at a much faster laptop when using Windows then using recovery of the vendor with all that crapy software. I myself just use Virtualbox when i need windows (Ms Office kind of applications).

 

I've just installed nvidia-346 from Xorg-edgers. Works like a sharm! :thumbsup:

 

I need to disable the touchpad while typing. It's always moving the cursor around and is maddening.

I see syndaemon running but it seems not to be doing the job. It runs with:

Code:

syndaemon -i 0.5 -k

I had the same problem with my T500 and never resolved it, but the touch pad was much smaller and it wasn't as troubling.

I'm running Mint 17.1 with MATE. I would switch to another desktop in a heartbeat if it would help to solve this issue!

I'm also curious to know if there are any Y50 specific packages I should be installing.

Thanks!

 

I installed Touchpad indicator. it gives you a lot of features. Maybe that would be a solution. Look at one of my previous comments.

 

Thanks for the suggestion. I'm giving it a try. I also found this:

Code:

synclient PalmDetect=1

That seems to help as well.

The first seems to actually disable the touchpad while typing and the other prevents palm detection from moving the cursor around.

Thanks!

Incidentally, synclient seems to expose a lot of settings not visible in any control panel or other GUI tool:

Well, I gave this a try, booted to black screen again. I was able to recover by going to runlevel 3 and removing nvidia-346 and nvidia-opencl-icd-346 and installing nvidia-opencl-icd-331. I'm pretty much ready to give up on this.

 

I have a y50 and the fans are running pretty high and the cpu temp is around 50c when idle, so when it starts playing a game, it gets pretty loud. Is that normal for this laptop and anything I can do about it? This is on Xubuntu 14.04 and also the fans are pretty loud on Windows as well.

 

@d10sfan - you should check out ubuntuforums.org. I see a lot in there for the Y50. I haven't seen your specific issue, but search the forum and you may find something that I missed. I'm on UbuntuGnome and my fans are silent.

In general, I remember someone mentioning that their sub didn't work. I'm wondering if they fixed this. I always use headphones at work and home but would like to get everything working properly.

Has anyone tried multitouch on the touchpad in Ubuntu in unity or gnome? I'd like to get this to work as it would make things easier.

 

Hello guys! I'm new in the forum and I'm glad I found an specific thread about this notebooks and linux

I tried to install ubuntu/linux mint/fedora and with all this distros I had problems with the wireless driver. The driver is:

Network controller: Broadcom Corporation BCM4352 802.11ac Wireless Network Adapter (rev 03)

And I know some of you have successfully installed linux, so I want to ask how could you make the wireless chipset work?

I apologize in advance if some of you did the same question and obtains a successful answer. I really want to make this works, I don't
want to use Windows anymore!! (except for gaming of course )

Thanks a lot!!!

 

Hi all, thinking about buying a Y50 tonite. Promarly for development in Linux.

Anyone know what the difference is on the lenovo website in the price? Base model is $899 and the next one is $949.

Is the 4720hq a big difference from the 4710? Am I going to notice the .1ghz?

Also, what WiFi ac 2x2 card does that it use? Why does the $949 model have the cheaper 3160 card, is one better than the other ?

Looking to purchase tonite and it seems they both also have IPS screens now.

 

Did anyone manage to get subwoofer working under linux yet?
