Bug Description

Binary package hint: xorg

I have a Toshiba Satellite Pro A120 on which I have been running feisty with no problems at all.

I upgraded to gutsy and have had constant problems since. The problem never occurs when the machine is in use, only during idle time, either with the lid shut or simply after a period of non-use. Sometimes the machine will run for a day without this occurring and sometimes it happens at one.

Symptoms:

Screen become uniform grey. No cursor. No response to keys. No response to ctril-alt-backspace. No response to ctrl-alt-Fn. I can connect in via ssh and running top shows that Xorg is consuming 100% of one processor. The power butting does not respond, so unless I have access to a machine to ssh from I have to restart by unplugging power and battery,

What I have tried:

No desktop effects (compiz). No screensaver. Power management: never sleep, do nothing when lid closed, never put display to sleep.

Could you please attach the files '/var/log/Xorg.0.log', '/var/log/Xorg.0.log.old' and '~/.xsession-errors' and the output of 'of lspci -vvnn '?

This sounds a lot like what I describe in bug #155312. The solution for me was to switch from i810 to the driver called intel.

The intel driver seems to have worked for me too. I thought it hadn't at first, but that's another big ... "Screens and Graphics" refuses to put "intel" ito xorg.conf. I'll keep on testing ...

I've collected the reports about failures during mode switching (e.g. suspend/resume), such as bugs 138256 and 150109:

https://wiki.ubuntu.com/X/Bugs/ScreenModeChange

I'd encourage anyone with Intel graphics having problems with blank, black, or frozen screens after resume from suspend, hibernate, tty switch, and so on, to add data to that page, so we can get a more complete feel for what the bugs are.

I've also created a page summarizing how to analyze and work around these issues. It would be worthwhile for anyone experiencing these issues to review and try these steps, and then report their findings on the appropriate bug

Ian, thanks, good to hear that -intel solved it. -i810 is deprecated so we can close the bug now.
