Y50 - Linux thread

I have multi-touch running on Mint 17.1. At least I think so. I use two finger scrolling and two or three finger tapping to emulate right and middle mouse button. None of these are terribly reliable but they seem to work about as well as on Windows. Probably got by installing xserver-xorg-input-synaptics

I have a question about CPU fan speed. Is it available anywhere? lm-sensors does not report it. I'm also looking for a way to control battery charging since I have read that the battery will live longer if charge is cycled between (IIRC) 30%-80%.

 

Hello,

I recently picked up a Lenovo Y50 and wanted to experiment with running ubuntu again. My problem in the past was finding and installing all the right drivers. I'm pretty sure I need Intel and nVidia drivers to get Optimus working properly. Battery life is abysmal w. 1 1/2 hrs and battery drain at around 28whr. I ran the 64 bit 14.10 install, not installing any specific drivers manually so I don't even know what drivers I need. WiFi works, haven't testes bluetooth or ethernet. Any help will be appreciated, thanks!

 

I'm running Mint 17.1 which is based on Ubuntu but is likely not identical in all regards. Intel drivers worked 'out of the box.' Nvidia seemed elusive. I finally went to the Nvidia site and downloaded and installed 346.59. It seems like the nvidia drivers are now in use for everything (as opposed to bumblebee or optimus which AFAIK use the nvidia adapter for specific apps.) I took a stab at the others but they never seemed to work right. At times 'optirun' produced lower benchmarks than just running the bench without it.

I know I can switch back to Intel graphics only by changing the video setting in the BIOS. When I get brave/curious I'll try prime-switch. OK, just gave it a shot. nvidia-switch segfaults. 'nvidia-select intel' produces:

Code:

hbarta@yggdrasil ~ $ sudo prime-select intel

Maybe it wasn't such a good idea.

Edit: Seems to have made no difference. Nvidia drivers still in use after logging in again.

Edit-2: After reboot the system was again using the intel driver. 'sudo prime-select nvidia' followed by a reboot brought back the nvidia drivers. It's not much more convenient than switching via bios but it does seem to work.

The other wrinkle is the touchpad. I had that more or less sorted but wound up reinstalling for other reasons.
