View Full Version : [ubuntu] Direct Rendering problems with Intel Graphics Card

Today I decided to do a fresh install of Ubuntu 9.04. I am using an intel I810 graphics card, and running GLX Gears on the live CD showed that I was getting around 200 frames per second. After installing, I was still getting 200 frames per second, however whenever I tried to run any openGL application, it would be blurry or would simply freeze the system. Adding

Option "DRI" "off"
to my Xorg configuration file seems to have fixed the freezing problem, but now I'm only getting 64 frames per second, and I can't even run an openGL application with that, it's just too slow. Is there any way that I can enable the direct rendering and not have my computer freeze every time I open a fullscreen 3D application (like sauerbraten)?

Looking through my log files, I notice that moments before the system freezes, there is an error message:

*ERROR* unknown parameter 6
Just in case that helps... could this maybe be a bug in the intel display package?

*edit*
Related to bug 353049 (https://lists.ubuntu.com/archives/universe-bugs/2009-April/069936.html) maybe?

Well, depending on how adventurous you are.

Jaunty comes with linux image 2.6.28-11

There is a later image available 2.6.30-rc3

which gets back toward Intrepid performance with my two intel machines.

I downloaded it from:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30-rc3/linux-image-2.6.30-020630rc3-generic_2.6.30-020630rc3_i386.deb

I wind up with grub boot options for rc3 followed by the boot option for 2.6.28-11 so I can run either one.

Cheers, Jerry
