I'm not really sure whether my experience with Ubuntu Edgy I installed
recently applies to this, but I found out that X server crashes when
the screensaver starts or if I at Gdm login screen switch to console,
X server crashes when autologin starts.  The backtraces in X log
would seem to point to XAA/GLX/DRI.

My gfx card is Matrox G550, and the problem doesn't appear
if in the /etc/X11/xorg.conf I use following:
Section "Extensions"
        Option          "GLX"           "Disable"
        Option          "Composite"     "Disable"

I.e. disable 3D completely...  I saw in bug tracker some notes about
a bug where disabling (just) composite helped for crashes, which was
supposed to be fixed for Feisty, but for my crashing disabling whole
GLX was required.
