Public bug reported:

Binary package hint: xorg

Firing blind, but will update this as i find out more:

I'm using Lucid Lynx final release, fresh installed, on this system
(Samsung laptop R580, Intel Core i3@2,13 Ghz, 4 G RAM, nvidia 330M).
System has been in use for a few days with this install.

Symptoms: random hard system freezes where the screen either becomes
garbles or torn across the middle (vertically) with no cursor response
to mouse movement, OR (non-garbled) screen freeze with a short lasting
cursor response to mouse movement with a hard freeze of the screen and
all computer activity shortly after, OR an immediate freeze with no
response whatsoever to user input and no screen garbling.

Dropping out to TTY doesnt work; in all cases a hard shutdown is
required, as keyboard input becomes impossible.

Conditions:

Happens uniquely when Firefox is the foremost application and a Firefox
window is active. Freezes tend to happen with moderate windows and tab
number active (fx. 3 windows and perhaps 15 tabs in all).

Other active apps (typically): Pidgin, Vinagre, Nautilus, Gedit, System
monitor.

Other software of interest installed or in use on system: CPU Frequency
Scaling Monitor 2.30.0 (4x, one for each CPU core) attached to
gnomepanel. Gnome-do installed but never invoked at any time close to
crashes.

Other tests: Have been left on overnight with System monitor on the
resources overview to test of that would trigger a crash/freeze, which
it hasn't yet.

Therefore, I suspect that it is a bug in X-org, triggered by Firefox in
an unknown way.

I cannot attach apport information, as it does not report anything upon
reboot (no reports of kernel panics or the like).

System did not show any such behavior during testing Lucid from Beta 2
and up to RC.
