[i965] idle black screen plus other issues Ubuntu
I too am seeing the issue where the screen stays black but the mouse cursor
moves and changes shape normally.
Eventually, after some long amount of time (which varies from seconds to
minutes), the screen will suddenly restore as expected. I when it eventually
restores it's usually coincident
I have been experiencing the same problem, first with 11.10 and now with

It has happened a few times today and I tried the following commands

Running 'sudo service lightdm restart' fixes it by restarting the whole X

killing the xorg process causes a restart and gets things going again
without rebooting, but all your open gnome-based applications are closed
also. This is a very, very, very, very annoying bug.

Same problem here, using an integrated Intel GPU.
I have a nVidia too, it's normally switched of (due to the lack of Optimus
support), but i was wondering if using it is increasing the blackscreen

I'm having this problem with an Intel GMA videocard.
Sometimes it works to just kill gnome-screensaver, and today I managed to
recover by killing 'compiz' with a 'SIGUSR1' (after already having killed
gnome-screensaver). I wasn't able to check whether compiz has a nice restart
self command, but
Switched to Ubuntu classic (no unity, it's same gnome shell as previous
Ubuntu release had) and it's been working fine (no compiz either), no
crashes for more than a week.
BTW I remember similar problems with Intel driver (same machine) before
when I had compiz effects enabled. Now it seems much

typically i had just converted my whole family to ubuntu as this bug occurs XD
so we are now all stuck with this issue
I also have the screen blanking issue which requires a reboot to resolve
(Same behaviour, can only see the mouse pointer). This is a complete
show stopper for me as I now have to reboot far more frequently than in
windows.
I am not sure how widespread this is, but I can confirm it presents on
Also, disabling the screensaver/screen locking is a workaround, but not
one I'm happy with given the security implications on a laptop.

I just wanted to add to this discussion as I'm having almost all of the
same problems mentioned above. Black screens have not been as much of a
problem, although this has happened once or twice. However, my menu bar
items that are TEXT ONLY appear to be showing up in a barely visible
font color.
