Public bug reported:

Binary package hint: xserver-xorg-video-intel

I am using Kubuntu 8.04.1 (with all current updates installed) on an ASUS Eee 
1000H mini-notebook PC. I'm also using xrandr to switch off the LCD and use an 
external monitor with the machine while it's on my desk.
Xorg video driver is xserver-xorg-video-intel 2:2.2.1-1ubuntu13.6.
Video chipset is an Intel 945GME.

The problem is, if I switch from LCD to the VGA-out with xrandr, after a
few minutes to a few hours, the screen will change to a single solid
colour. Switching back to the LCD allows me to interact with the machine
again, but VGA-out remains black when I switch back to VGA again. Sync
is being output on the VGA port as the monitor is showing the resolution
I set it to in the Info screen. Only rebooting the machine will allow
VGA-out to work again -- simply restarting X has no effect on the VGA-
out issue.

I've tried enabling ForceEnablePipeA, but this had no effect on the
problem.

Typically, the video starts glitching when I switch from LCD to VGA-out.
It's about once every few minutes, and looks like the screen has missed
a sync pulse or something -- the video is shifted right (or maybe left?)
a bit for around 1 video frame. This starts happening a few minutes
before the video locks, but may not be related.

I have a suspicion that the recent driver update pushed to hardy-updates
may be the cause of this. I am going to revert to 2:2.2.1-1ubuntu12
later and see if this resolves the issue.

Other people have included the following in there bug reports -- I can't
see any firm requirement for the lspci dumps, but I have included them
anyway as they might be helpful, if only for accurately IDing the
chipset.
