What tweaks opensuse made that makes X4500 performs best?

Olnex · 2009-01-21 22:53:16

My laptop (toshiba U400) has X4500 intel video card which is not supported well currently in Linux, I tried Ubuntu 8.10, with its default xorg.conf, there are many problems, supertux runs very slowly, glxgears gives me average 300 fps. Then I tried Opensuse 11.1, kdm has a problem that the screen has random colors, when starting gdm and between login and desktop appears, but the Gnome version has no such problem, and glxgears give me average 600 fps.
Finally I tried Arch, I think the driver should be newer or at least equal to opensuse, so it may be better. Arch has no default graphical environment and I don't know how to write xorg.conf, so I just use the one from Opensuse. However, glxgears give me only average 400 fps, supertux runs fine.
Here is the xorg.conf i used from Opensuse, it has many suse-specific options, not too sure what tweaks do opensuse make:

EDIT
I also want to mention that I run glxgear in both opensuse and arch with no other application running, only a gnome-terminal that I can type the command. Also, in Arch, I scaled the core 2 duo CPU frequency to 2Ghz(both, highest), in Opensues I did not do this, not sure what default scaling it uses.

Glxgears is not an actual benchmark, so these numbers don't mean anything. If you can play your games just fine, then you're good.

What tweaks opensuse made that makes X4500 performs best?
