[Bug 257894] Re: VGA-out dies after a while on Eee 1000H

[Particlese]

I'm seeing this same problem on a Toshiba Satellite U205-S5057.  The VGA
screen goes black anywhere from a few seconds to several hours after I
log in.  (For the longer times, the VGA output flickers horizontally
every so often; I'm not sure what the time interval is.)  I noticed that
daemon.log shows scim-bridge quitting right before the display goes
black (see below), and this behavior started around the time that I
enabled scim-bridge, so I will see if disabling it fixes the problem.  I
could be a coincidence, though, because I also got some updates around
the same time.  Is anyone else here using scim-bridge and seeing similar
output in daemon.log?

Additionally, when the VGA screen goes black, I use
xrandr --output LVDS --auto
to turn the built-in screen back on.  When I try
xrandr --output VGA --off
I get dumped back to the login screen as if I had hit ctrl+alt+backspace.

Here is the lspci output relating to the onboard video:
00:00.0 Host bridge: Intel Corporation Mobile 945GM/PM/GMS, 943/940GML and 945GT Express Memory Controller Hub (rev 03)
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)
00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03)

Here is the output from /var/log/daemon.log.  The second line through the last represents the window during which the VGA output went black, and probably up to the point where I was back at the login screen.  The last line is the end of the log.

Also, /var/log/Xorg.0.log shows a lot of these:
(EE) intel(0): underrun on pipe A!
but there's no time to correlate it with the daemon.log output.
