Public bug reported:
Binary package hint: xserver-xorg-video-intel
The display starts flashing (like brightness turning up and down really
fast) and is generally unresponsive, the following error appears in
dmesg:
[drm:i915_get_vblank_counter] *ERROR* trying to get vblank count for
disabled pipe 0
I'm able to move the mouse and choice shutdown however I'm unable to
click the shutdown button in the dialog. Also the dialog does _not_
count down. Other open programs respond extremely sluggish as well.
Switching to a console allows me to log in, however as soon as I login
in the screen is filled with "^@"s, pressing Ctrl-C resulting in me
being logged out again.
The only way to recover is to hard reset, soft reboot results in the
same symptoms immediately after reboot.
Reproducing this problem is not consistent. Certain programs seem to
trigger them more often. Especially Skype (2.0.0.72-1), but also the
Gnome screensaver. Disabling compiz or switching to different themes
does not help.
I'm running Ubuntu karmic on a MSI Wind Netbook 100 (Intel Atom N270,
Intel 945GSE+ICH7M).
