[GM45] system frozen after a period of inactivity

This bug today presented even with -7 kernel, so the problem should be in the intel driver.

Immediately after the screen blanks I can recover it moving the mouse.
I left the pc on for 30 minutes. Now it's not possible to recover it.

I also added gnome-power-manager because when I close the laptop lid it freezes again (if set to blank screen)

Marking gnome-power-manager task as invalid. I see no incorrect behaviour from the power manager.

I also see this bug. It appears to be triggered by turning off the display with DPMS. Once the display has been turned off, X seems unable to turn it back on. The laptop is still responsive - network & activity continues, and if KMS is enabled, SAKing X will turn the screen back on. Confirming for the DDX component; I'm not sure why this would be kernel-related when not using KMS. I'll do some more testing.

Argh. I might have been premature in discounting the kernel. "xset dpms force {off|standby|suspend}" does *not* trigger this bug. Perhaps it's something to do with turning off the backlight?

try to wait some minutes, after setting the dpms off

I've noted similar behaviour on

00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)

same here on:
00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03)

I've also tried xset dpms force off and left there for 1 hour. no freeze.
Is it possible that gnome-power manager uses another method?

Here's another device which is experiencing the same problem.
00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)

I managed to ssh to my box after the crash: I collected the dmesg output.
I cannot even reboot because sudo reboot crashes

xset causes the crash (well tested twice):
- sleep 10; xset dpms force off
- close the lid
- go to sleep
- wake up
- open the lid
everything black!

Bryce, since I can ssh login after the crash, can you tell me which commands should I execute to gather as most info as possible?

This has the same call trace as 388357, but that does not necessarily prove it is a dupe - the only real way is to collect a batchbuffer dump. Please follow the directions on this page to collect it. A dump is also required in order for us to forward the bug upstream for further work:

This is a very common dpms problem that was fixed just recently in the intel driver, and the regression was introduced in the "Sync DRI2 CopyRegion to vertical retrace" commit on 6/02 that snuck into karmic. If you want to test the fix, please add this PPA to your sources and pull in all of the upgrades.

yes, it seems fixed with the PPA you gave me
