Bug Description

I'm using a Toshiba U200-163 laptop. https://wiki.ubuntu.com/LaptopTestingTeam/ToshibaSatelliteU200-163

After a fresh Ubuntu 8.04 install, without any installed packages, I noticed that the laptop screen randomly goes blank without any way to recover the session. This happens generaly in the 2 minutes following a cold boot then every 30minutes-one hour, needing each time a reboot.

All tty are killed, nothing is displayed. The computer seems to be still responsive because pressing the "power" button twice restart the computer, which is the only way to recover.

/var/log/syslog :

It seems that this X.org killing happens only when doing something "heavy" on the desktop. So far, it was :
- switching to a charged desktop (several times)
- displaying a complex webpage such as a launchpad form (crashed when clicking on a widget)
- displaying the calendar in evolution

I puttet INTEL_BATCH=1 in /etc/environment and it seems to solve this bug.

Unfortunatly, it is said that it should not be a default ( bug #195843 )

So what ? An unusable system by default ?

It seems to be related to the video driver

When reporting X issues, please always attach your Xorg.0.log. Also, when reporting crashes please remember to attach backtraces, because we cannot begin troubleshooting without having that info. See http://wiki.ubuntu.com/DebuggingXorg for details on this.

As I'm sure you read in bug #195843, upstream says that INTEL_BATCH=1 is not supported and can make a system less stable, so we would not consider that an acceptable fix for this issue - it might result in making your specific system more stable by default, but make everyone else's less stable. Also, I suspect INTEL_BATCH=1 may not have solved your issue, just hidden it.

It would also be good to rule out memory issues, since bad RAM can typically exhibit problems like this. Please run a memory checker to verify your memory is ok. If it is, then attach the Xorg.0.log and backtraces.
