[Hardy] GUI disappears while working

[Shirish Agarwal]

Binary package hint: xorg

I just been doing the updates, from the last couple of updates, the monitor randomly stops working. I have put power management at 12 mins, I am also using BOINC Manager to do some crunching but don't think it affects in some manner. While working the monitor stops responding & even trying to cycle through alternate consoles doesn't get me anywhere. Would be attaching my Xorg logs maybe that might give you some indication as well as my conf file.

as can be seen I'm using the intel driver 2:2.1.99-1ubuntu1, lemme know if any more details are needed.

[Shirish Agarwal (shirishag75)]

Could it be also be partly due to https://bugs.edge.launchpad.net/ubuntu/+source/acpi-support/+bug/164001 that I filed.

Turn off Desktop Effects in Preferences / Appearance and see if this error still happens to you.

Przemyslaw ,
 Desktop Effects is turned off but the lockup still happens to me.

From the Ubuntu X Debuggers handbook I think it would be best to say that the screen display gets corrupted.

[Shirish Agarwal (shirishag75)]

This time it got corrupted while I had paused an .avi file. Here's the .xsession-errors file. The X Ubuntu debuggers book doesn't have instructions what to do in the case of corruption of video playback. https://wiki.ubuntu.com/X/Debugging . Please add that info. so I can test it.

I've noticed several other reports that sound similar to this (the GUI going blank after some random period of time). It may be worth investigating if there are dupes for this bug. In any case, it looks like the reporter has provided ample details, so am marking the bug Triaged, and ready to be reported upstream.

[Bryce Harrington (bryce)]

Before I forward this upstream, could you please test and let me know if this issue is still happening?

[Shirish Agarwal (shirishag75)]

From couple of updates last, it seems the issue is fixed for now. Thank you for following it up :)

[Bryce Harrington (bryce)]

Excellent, thanks for letting us know!
