Comment 6 for bug 357290

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@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@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
