INTEL graphic slow again since 2.6.30

Hi everybody, i've upgraded from 2.6.29 to 2.6.30 kernel today and my intel gma950 works shitty again. From 1200 FPS which i had in glxgears performance lowers to 260 FPS, games like UT2004 doesn't work, compiz is slow etc. Is anybody experiencing same problem?

It's probably because of this bug:

http://lkml.org/lkml/2009/6/5/92

Look for such messages in the logs to be sure.

The patch is not in 2.6.30 AFAIK. As Andrew said, will probably show up in 2.6.30.1

Just be patient, u can compile your own 2.6.31 kernel or wait for the official one to hit the repos, I expect it in a month or two...

Re: INTEL graphic slow again since 2.6.30

I run an intel GMA X4500 graphics chipset in my notebook.   While the performance is bad by default (no xorg.conf) its pretty decent with

        Option      "MigrationHeuristic" "greedy"
        Option      "AccelMethod" "exa"

in the device section.

Did you try?
- not using KMS on boot
- reverting to xf86-video-intel-legacy
- disabling compiz (do you prefer eye candy or smoothness?)

Re: INTEL graphic slow again since 2.6.30

A quick grep through the kernel gitweb tells me that the patch has been merged into 2.6.31, but not 2.6.30.x (yet, it still might).
You may want to try patching your 2.6.30.x kernel manually if you're feeling daring.
Also, it appears there are other patches to be merged: "In combination with the pre-965 tiling patches I posted earlier (which Eric is now integrating), you should see a big performance improvement if you have an affected machine." -- Jesse Barnes

And don't worry, Morton feels your pain
"Wanna show us the patch?
Because the world could certainly do with more i915 bugfixes " -- Andrew Morton
