    Pushing the GPU too far?

    I have a CF-29 with 1.25 GB of RAM Installed. I had been experiencing hard lockups while playing YouTube videos but haven't had any problems since turning off hardware acceleration in flash. Last night I started to watch a streaming video off the comedy central website which was obviously a high res and had no option to lower it. The video was skipping frames a little bit but nothing major and the video was still watchable. After about 7 minuets or so the video started to stutter bad, I tried moving the mouse and that was moving slow also then the machine froze. Closing the lid did not turn off the display and I had to do a hard reset.

    I'm just curious if others with the CF-29 can watch all kinds of streaming video with impunity or if I was just pushing the GPU further than it was meant to go. I replaced the thermal pads and my CPU temp rarely breaks 60 C but I'm unable to monitor the GPU temp because there is not sensor. Any feedback or similar experiences would be appreciated, thanks. BTW, I'm running CrunchBang Linux.

    Maybe a problem of the intel video driver..Kms + newer intel driver + older intel graphic controller (i8xx)= lockups
    Tell we what version of intel driver,xorg,etc you're using.

    It looks you have Kms enabled..try to look for "Gpu Hung" in /var/log/errors.log Xorg.0.log and other log files.

    What video card do you have? lspci |grep Display
    What version of the intel driver do you have? search intel in package manager

    Try this video driver Intel Linux Graphics: 2009Q3 it's the last intel driver that doesn't require Kms.
    To disable Kms add i915.modeset=0 in grub's menu.lst

    I have flash 10.3.183

    ps.I'll try to run Fallout2 in my cf-28 linux :)

    Archlinux,latest xorg 1.9,intel 2.16.0 ,and I experienced some video lockups. 8xx chipsets have hardware bugs exposed in the newer intel drivers.

    Try to downgrade to 2.9.0 and disable kms then play that video again.

    Don't really see how I can downgrade easily.

    Deregter,

    Downgrade what? Archlinux?, Intel? And then how to do it?

    This is good information but would you please expand a bit?

    Then we'll get to the question of running Ubuntu 10.04 on a CF-30Mark2 with-out disabling acpi in the boot menu. :D

    Thanks.

    Jeff

    I tried to downgrade xorg-server (1.7.x or 1.8.x),xorg input drivers,xf86 intel driver (2.9.0),libdrm,libgl,intel-dri by downloading old packages but I failed,I'm still figuring it out.. I'm not sure about the right versions of the packages,trial and error practice,and I dont know how they are called on debian distros..


    To downgrade you can search for old packages (out of sync mirrors) or try to compile the packages (difficult task,they'll break) then install them and eventually modify xorg.conf and other config files. https://wiki.archlinux.org/index.php/Downgrading_Packages#Finding_Your_Older_Version

    Another way is installing an old distro with the good old drivers,then update it ignoring the update of xorg,intel and any related package.

    @vaulttec: I'd try to download that high res video with firefox's videodownloadhelper plugin or similar,then playing it with mplayer launched from a console,to exclude a flash problem.

    Sorry for my bad english.

    I downloaded the intel 2.9.0 driver but installing it was a no go. While I'm not a expert I have been using linux for a few years and I'm not sure if downgrading this way is possible. I can't find a package file and if I try to compile from scratch I'm missing dependencies (outdated stuff I suspect). Using an older distro and pinning the intel driver so it doesn't update may be an option but I would rather avoid it.

    I had been getting freezes when using xubuntu but since switching to crunchbang things have been alright. I get no lockups while watching youtube now that I've turned off hardware acceleration in flash. I acknowledge that the video I was watching during this last freeze may have been pushing it for the older hardware on this laptop. I would just like to know if the lockup was the gpu being pushed to far or the linux driver screwing up. Like I said the logs didn't show anything that I could. BTW, your English is fine.

    Sadlmkr,

    Have you had video lockups with Ubuntu on the CF-29?
