glxgears really jerky on Maverick

[Eric Boissard]

Hello,

Since I have upgraded (even reinstalled from scratch )from Ubuntu Lucid to Ubuntu Maverick, glxgears is really jerky on my eeePC 1000H (intel 945GM card using i915 module). I checked that direct rendering is enabled. The strange thing is that if I move the mouse while running glxgears, it becomes smooth and the framerate goes up to roughly 60fps (vsync is enabled by default in the new intel driver if I am not wrong). As soon as I stop moving the mouse it becomes jerky and the framerate goes down around 20-30 fps.
Everything was fine on lucid. I know that glxgears is not a benchmark, but it should be running smooth anyway.

see those threads on the forum:
http://ubuntuforums.org/showthread.php?t=1594350
http://ubuntuforums.org/showthread.php?t=1591565

First I thought it was something related to the kernel, I tried different kernels like 2.6.35 and 2.6.36 but I had the same issues.
however I went back to lucid and upgraded to the maverick backported kernel 2.6.35 and glxgears is running fine and smooth.

I tried to run glxgears with and without compiz and it does not change anything.

I also tried other distributions, Mint Linux 10RC and fedora 14 beta and I have exactly the same issues. I tried to use the X-Updates ppa on ubuntu but it did not improve anything. I am now back on lucid with maverick backported kernel 2.6.35, however I have noticed that I have the same errors when I do dmesg. Only the drm errors was present even in lucid default kernel (2.6.32). However both errors are present on Lucid and Maverick with kernel 2.6.35.

I have not changed anything, the issue is present on the live CDs and with all the distribs I have tested.

I hope it can help. It might be related to xserver-xorg-video-intel ? I cannot really tell.

Thanks a lot for looking at this issue.

Hello Eric
can you add
/var/log/syslog
/var/log/ker.log
/var/log/Xorg.0.log
/var/log/Xorg.1.log
fabio

[Eric Boissard (eric-boissard)]

Hello fabio,

I have done a clean install of Maverick on my eee 1000H with all the latest updates. The problem is still there.
Some of the files you are asking are missing on my computer:

(/var/log/ker.log and /var/log/Xorg.1.log)

Anyway I'm sending you the files I have. I hope it will help.

Thanks

[Fabio Marconi (fabiomarconi)]

hello
can you please run in a terminal

I think you meant /var/log/kern.log and not /var/log/ker.log so here's the file.

Just to add something I have just noticed, I simply need to keep a finger on the touchpad or simply keep pressing the left button to get glxgears running smooth at roughly 60fps. No need actually to move the mouse cursor.

[Eric Boissard (eric-boissard)]

I'm still trying 'things' to know a bit more about this bug. I tried today to use the latest intel drivers through that ppa:
ppa:glasen/intel-driver and it does not improve things.

[Eric Boissard (eric-boissard)]

I just found this interesting link:
https://bugs.freedesktop.org/show_bug.cgi?id=30364

[Eric Boissard (eric-boissard)]

Another update, after searching and reading a few things related to that issue, I tried to add 'nohz=off' as a parameter in grub. It fixes the issue and glxgears is totally smooth and sync at 60hz.
Now, I suppose it is really a workaround and does not actually fix the bug. However I would be glad to know the consequences. I suppose it will increase the power consumption and decrease the battery length. Am I right ?

[Jeremy Foshee (jeremyfoshee)]

Hi Eric,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 665117

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

    [This is an automated message. Apologies if it has reached you inappropriately; please just reply to this message indicating so.]

[Eric Boissard (eric-boissard)]

I have tested it on my current Maverick version (I have installed all the updates), using the latest kernel:
 2.6.35-23-generic #41-Ubuntu SMP Wed Nov 24 10:18:49 UTC 2010 i686 GNU/Linux

and the latest intel drivers from this ppa:glasen/intel-driver

I have exactly the same issues (glxgears is really jerky until I move the mouse, or simply run glxgears in fullscreen window. Basically, giving more work to the CPU seems to fix the issue). However if I add 'nohz=off' to grub parameters, glxgears is smooth again.

See this thread https://bugs.freedesktop.org/show_bug.cgi?id=30364, this is exactly the issue I am having.

I am thinking about trying natty today on a USB stick and see if I have the same issue.

Eric

[Eric Boissard (eric-boissard)]

I have just tested the daily build of Natty on a USB stick and I have exactly the same issue. Is there an easy way to try lucid intel i915 driver with Maverick ?

Thanks
