Hello,
I experimented this bug with Ubuntu 8.04 Hardy, too. Now I'm using
Debian Testing (Lenny) and also have the same - or quite similar - bug
(see: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=482819 ).
Just for completeness: I have performed several more tests, and in some
cases now I also suffer the freeze when switching to VT (CTRL+ALT+F1),
specially if I do it soon (less than 1 min ?) after entering my gnome
session.
I guess it may be in fact a DRI related problem, however I do NOT bet on
it. Please tell if adding the following to your (original auto-
configured xorg.conf) exacerbates the problem:
Section "DRI"
Mode 0666
EndSection
(It seemed in my case, but I'm not sure).
On the other hand, test if this limits the problem (once again, to your
original xorg.conf):
Section "Module"
Disable "glx"
Disable "dri"
EndSection
(It seems it limits it in my case? - not quite sure either)
In addition, I have to say that in my Debian Lenny, package libgl-mesa-
dri was not installed by default. After installing it I removed some
warning messages in my Xorg.0.log, but with little variation in
behaviour (I dare to say that crashes when switching to console started
after that??).
Just another remote possibility: my laptop also has a WIFI ipw2200
interface. I think I have noticed higher X crash probability when
Network Manager applet cannot connect to my wireless network ?.
Ah, I also have the console vesa framebuffer enabled, by adding the
vga=788 parameter to my kernel boot.
Anyway, as this is all quite random, I am not sure at all of anything.
Regards,
