[Bug 357290] Re: intel 945gm graphics card no 3d acceleration when running 3d games and apps

[Graham Watson]

Hi,

My report on the given wiki page:

Problem: /dev/dri/card0 is missing.
Problem: /dev/dri/card0 permissions are incorrect.

    - The file exists on my install as follows:
        crw-rw----+ 1 root video 226, 0 2009-04-10 00:12 card0

graham at graham-ubuntu:/dev/dri$ getfacl /dev/dri/card0
getfacl: Removing leading '/' from absolute path names
# file: dev/dri/card0
# owner: root
# group: video
user::rw-
user:graham:rw-
group::rw-
mask::rw-
other::---


Problem: Falling back to OpenGL software rendering

graham at graham-ubuntu:/dev/dri$ glxinfo | grep render
get fences failed: -1
param: 6, val: 0
direct rendering: Yes
OpenGL renderer string: Mesa DRI Intel(R) 945GM GEM 20090326 2009Q1 RC2 
x86/MMX/SSE2


Problem: UXA gives better performance than EXA - why not move to UXA?

    - This seems to have fixed the problem for me. Neverball and the 
other 3d apps I use are now running silky smooth even with th desktop 
effects set to full. Google Earth however is still maintaining 1fps.

Many thanks, and I'll keep you posted if I find any further problems 
with this experimental driver.

If you have any ideas why Google Earth still likes 1fps I'd appreciate 
it. It runs very smooth on my 'other' OS on the same PC (are we allowed 
to say that?).

Regards
Graham
