[Intrepid] No 3D acceleration for intel driver version 2.4.1

[Juha Tiensyrjä]

I did a aptitude full-upgrade on my Intrepid laptop today, and xserver-xorg-video-intel was also updated from version 2.4.0-1ubuntu1 to 2.4.1-1ubuntu1. After a reboot KDE 4.1 would not start correctly. After a while I managed to switch off desktop effects, which made the desktop work. After experimenting with various 3D software (glxgears, nexuiz) it was obvious that 3D acceleration was broken. With the previous driver version 3D acceleration worked.

I am running an up-to-date Intrepid Ibex on a Lenovo Thinkpad X60s with an Intel 945GM graphics adapter.

uname -a:

Glxinfo reports the following (the rest is attached): Failed to initialize TTM buffer manager. Falling back to classic.
Glxgears says: Error: couldn't get an RGB, Double-buffered visual

It's not the DDX driver (-intel) that broke it, but the DRI part (mesa). Same thing on my GM965.

This is actually fixed in the latest xorg-server upload (uploaded a minute ago). Upgrade once it's in the archive.
