[gentoo-user] xorg-server-1.5.* and compiz-fusion on intel 945GM

[AJ Spagnoletti]

For the past month I have been trying to figure this issue out to no
avail. When the new xorg-server went stable a little over a month ago
there were several posts related to opengl performance on the intel
graphics cards none of which I was able to pull any information from.
Prior to the upgrade, while running xorg-server 1.3 and intel video
driver 2.1, I was able to run gnome with compiz-fusion (no flames on
gnome please) without issue, and glxgears (yes I know that its not a
benchmarking tool but it will illustrate the point just fine here) ran
at about 700 fps. After the upgrade which included:

xf86-video-intel-2.7.1
mesa-7.4.2
xorg-server-1.5.3-r6
libdrm-2.4.11

My performance has dropped to the point where compiz-fusion no longer
runs well on my computer. glxgears shows only 60 fps. Following some
suggestions from earlier posts to the list I have tried upgrading my
kernel and now run 2.6.28 with the i915 driver in the kernel selected.
glxinfo shows:

OpenGL renderer string: Mesa DRI Intel(R) 945GM GEM 20090114

Anyone have any ideas that may help improve the performance on this
card, FWIW the laptop is a Dell Inspiron E1405 with a GMA950 Intel
chipset.

Thanks,
