Public bug reported:
Binary package hint: xorg
Hardware: laptop dell latitude, integrated intel graphic card
Software: up to date hardy AMD64 (updated from gutsy and followed half of hardy
devel cycle, I'll check with a fresh install when I have time to do so). compiz
is disabled, it happens when using EXA and XAA.
Since when: I'm pretty sure the bug was not present in gutsy but I didn't use
much this laptop during hardy cycle so I can't tell for sure
the system works fine but freezez from time to time (i.e. the mouse
doesn't move, keybord is not responsive, even sysreq are most of the
time useless - I couldn't try an ssh connection yet. After disabling
compiz it still happens and seems to be related to my use of evince or
openoffice. It look like I can reproduce it quite reliably by launching
evince and playing with the scrollbar to force it to redraw tons of
things. It take a variable amount of time but always freezes if I insist
(it also freezes when I'm reading normally but this is a bit random).
I also tried using XAA without any luck
