Public bug reported:
I have my computer set to lock the screen after 10 minutes of
inactivity. A while after that it turns off the display.
Since 3 weeks ago, when I leave it for extended periods, i.e. I go to
sleep, on moving the mouse to turn the screen back on and get the unlock
dialog, the screen is corrupted, and is in a series of thin, horizontal
strips each offset from the one above (like wooden floorboards).
It's irrecoverable from this state, and hitting ctrl+alt+backspace to
restart X makes it exit X, and hang, displaying only the results of the
init scripts which run on startup (i.e. whatever is on the display
before Xorg starts).
My System:
Ubuntu 8.04
01:00.0 VGA compatible controller: nVidia Corporation NV11 [GeForce2 MX/MX 400]
(rev b2)
Abit KX333R Motherboard
Beryl is not enabled, but the "restricted driver" for Xorg is enabled so
that I get accelerated graphics.
The only odd thing in Xorg log is this line:
(EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not
found)
But it may not be related, and is probably invalid, because earlier on
it says:
(II) LoadModule: "glx"
(II) Loading /usr/lib/xorg/modules/extensions//libglx.so
(II) Module glx: vendor="NVIDIA Corporation"
compiled for 4.0.2, module version = 1.0.0
Module class: X.Org Server Extension
ABI class: X.Org Server Extension, version 0.1
(II) NVIDIA GLX Module 96.43.05 Tue Jan 22 20:11:30 PST 2008
(II) Loading extension GLX
(II) LoadModule: "v4l"
... etc
