[Bug 445056] Re: [i945] [i945] (UXA) Intel Corporation 82945G/GZ Integrated Graphics Controller [8086:2772] (rev 02) freezes

[David Martín Clavo]

I am running into a similar situation: after a fresh Karmic install (lpia architecture) in my machine, the screen froze completely seconds after logging in (including the mouse).
The only solution was to enter in safe mode via grub and disable desktop effects. If I enable them, things work for a few seconds until the screen freezes. For example, I can click on a few menus, move windows, etc. and I see the right effects (fade in, fade out, etc.) until it freezes.

I have the same graphics (82945G/GZ), in a CoolBox Minidesk 2002
computer (Atom 330, 2GB Ram, FoxConn motherboard).

I installed Ubuntu Karmic 9.10 with the alternate installer for lpia architecture.
My xserver-xorg-video-intel package version is 2:2.9.0-1ubuntu2

The "compiz-check" script prints this:
