X Freezes when un-blanking screen

[hazelsct]

I just updated xserver-xorg-core and xserver-common this morning to version 2:1.7.6-2ubuntu7.5 and have had three freezes today when un-blanking the screen which I've never seen before. Both times it seemed to be re-drawing the screen, and froze in the middle of that process, so shaded window borders were etched but not re-filled, etc. Can't switch to a text VT via ctrl-alt-f1 etc, can't ctrl-alt-delete. Pushing the power button briefly results in hard drive activity, otherwise the machine is completely unresponsive.

I run compiz with Lucid, and had open: OO.o, Evolution, Firefox, Emacs 23, Gnumeric, and GNOME Terminal open (I think GIMP the first time as well, but not the second). Intel driver (version 2:2.9.1-3ubuntu5 installed 2010-05-31), Mobile GM965/GL960 rev 0c on a Dell Latitude D830n (= D830 without Windows).

One more thing: I changed the laptop power management settings to blank the screen when I close the lid, not put it to sleep, and all of these freezes occurred when I opened the lid.

(Unfortunately, the only other options are to suspend, hibernate, and shut down, all of which are unacceptable because I close the lid while running long jobs -- so much for a workaround. Hmm, wishlist bug against gnome-power-manager...)

Are you using compiz?

[Bryce Harrington (bryce)]

Are you still having this issue?

Fwiw, the change in 2:1.7.6-2ubuntu7.5 simply fixes a null deref issue; not something likely to cause an X freeze. However, you could try downgrading xserver to an earlier version just to be absolutely certain.

Issues related to unblanking screen more generally are due to faults in the power management settings. So I would suspect gnome-power-manager or the kernel to be more likely culprits.

Very sorry about the delay in getting back to you..

Haven't seen it in many months (maybe a year?) at this point. I don't
know whether it was resolved in a more recent X update. This may be
fixed.

To answer your earlier question, yes, using compiz, and still running
10.04, will probably upgrade to 11.10 "soon".
