[ubuntu-x] -intel 2.3.1 driver builds for Intrepid / Hardy

[Martin Olsson]

Hi Bryce (et al),

Here are some gtkperf numbers taken with an i386 machine and a X3100 
(965GM) card (see below). I'm also getting stuttering fullscreen video 
playback with the new driver + compiz as mentioned earlier by others. I 
also found a performance testing utility called x11perf but it wasn't as 
slick as gtkperf so I didn't bother with it.

Also FYI; I can confirm that this bug still exists in 2.3.1:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/234768

As for the performance:

WITHOUT compiz pixbufs got faster but everything else got slower 
including text rendering and scrolling which took 67% longer with the 
new driver.

WITH compiz every single benchmark is slower with the new driver (except 
GtkEntry which is equal).





Here the raw numbers as printed by gtkperf:
