Public bug reported:

Binary package hint: xorg

I have had Karmic running for a few weeks now, with no issues.  An
IBMThinkpad T42p, with an external monitor connected as well as the
laptop screen.  Recently, after the last Karmic update via the update
manager, my laptop screen randomly just turns off.  The attached screen
is fine and if I depress Fn+F7 a few times (5) the screen will re-appear
with all the apps, icons etc. untouched.  If I am watching a video with
say VLC, it will continue to run and you can hear the sound.

I have adjusted the screen saver and power management for both AC and
battery power, turning off everything I can.  Doesn't help.  I have
turned off gnome-power-manager via killall, still screen laptop will
blank randomly.  If however, I remove the power from the laptop
(i.e.running on battery), then it stops, until I put the power back in,
then eventually the laptop screen will blank again.  So this could be
apic or some other issue?
