Hi everyone,
I use the thinkpad X61s with Intel Graphics Mobile GM965/GL960 running
Gentoo.
Since an update on Monday I cannot get my X to work the smooth way it
was working before.
1) The 2D performance feels very slack, Redrawing Windows just takes
longer than it took before and reaction times in general are worse.
2) glxgears performance is down to 50FPS (200FPS before, but I remember
1000FPS a year ago), but reading about kernel 2.6.29 probably it should
be this way.
3) Googleearth is very slow
4) X consumes more CPU 10-14 percent when showing 'top' in an xterm, up
to a whole cpu when using firefox.
5) After using it a while(2 hours, say) X consumes a lot of memory and
responsiveness and performance start getting worse and worse. Feels like
some memory leakage.
The things updated are kernel from 2.6.27 to 2.6.29, mesa from 7.3 to
7.4, intel driver from 2.6.1 to 2.6.3.
The Xorg Version is 1.5.3 and unchanged.
Unfortunately I upgraded all these things at once, which is a mistake,
but well.
Now, the fun thing is that switching back makes the sluggish behaviour
1-4, go away, but 5 stays and I thought I reverted everything back to
the original state but it is still there.
Does anybody know a consistent guide how to configure kernel and Xorg to
be on the safe side for the future ?
Here is glxinfo, just if it matters

The fundamental theorem of algebra is open source. Like any other
mathematical theorem it can be applied free of charge and everybody
has access to its proof and can convince himself how it works. Why
should software be any different?
