i915 driver slowdown after 1-2 days?

i915 driver slowdown after 1-2 days?

[Chun-Yu Shei]

Hi,

I'm currently running xf86-video-intel 2.13.0 with an i5-540M, and I've 
been experiencing a strange issue where after a day or two, I can no 
longer play videos smoothly in Flash 10.2 beta, as well as in VMWare. 
Even moving windows in VMWare guests becomes slow and visibly laggy. 
It's almost as if there's no video acceleration -- the frame rate drops 
drastically, and CPU usage seems to increase significantly.  Playing 
video in mplayer still works perfectly, however.  Restarting X has no 
effect, and I have to do a full reboot to get rid of the problem.  I'm 
running 64-bit Gentoo with the following:

libdrm 2.4.22
mesa 7.8.2
2.6.36 kernel
xorg-server 1.7.7

The problem also occurs with the 2.6.35 kernel, and I've also been able 
to replicate it in a fresh install of Ubuntu 10.10.  There are no 
indications of any problems in both the output of dmesg and the Xorg 
logs, and the output of intel_gpu_top looks no different before/after 
the problem occues.  I'm on a ThinkPad X201 with an external display 
connected via DisplayPort, and I do suspend it with the hibernate-ram 
script.  Is this a known problem by any chance?  If not, how might I go 
about troubleshooting this?

Thanks,
Chun-Yu

reading your report it is not clear for me, if hibernating is necessary
to trigger the problem or not.


Thanks,

Paul

I cannot say for sure if hibernating is necessary to trigger the problem 
or not... every time I've seen the problem, it's been after using 
hibernate-ram a couple of times, but I also haven't left the laptop 
running continuously for a couple of days before.  I usually carry my 
laptop with me during the day, so it's not really practical to leave it 
on continuously.  It definitely doesn't happen immediately after 
resuming from suspend, though.  I can resume from suspend, watch some 
YouTube videos with no problem, and have the problem pop up a couple of 
hours later.

This bug is the only issue preventing me from switching exclusively to 
linux, so I really hope to find a fix for it -- I just don't know where 
to start. (I also hope for the ability to independently load separate 
color profiles for each monitor using xcalib, but that's minor)

I am replying to the list again and hope the developers will be able to
help you. If you do not get a reply in a couple of days I suggest to
open a ticket in the bug tracker [1].


Thanks,

Paul
