What happens if you do 'xset dpms force off ; sleep 3 ; xset dpms force on' ? Does the screen come back? Yeah, that does exactly what you'd expect: panel turns off for three seconds, then comes back just as it was. When you open the lid, the screen/backlight turns *on*, but it's black. Nothing seems to revive it short of suspend/resume. Interestingly, trying to kill X when it's in this state (ssh laptop.local, sudo telinit 3) causes it to hard-lock - no keyboard input, can't suspend, etc. Same for me on my T61p turns off for three seconds then comes back just as it was. ( xset dpms force off ; sleep 3 ; xset dpms force on" ) which makes me wonder if this is actually caused by something that happens after we close the lid and leave it closed for x period of time. something has started like the screen-saver or something that locks out the monitor.. (In reply to comment #0) > Attaching Xorg.0.log, so mcepl won't yell at me :D I don't yell at anybody (mostly ;-)). But there is apparently not much to do and ajax is here, so I will let him to have a fun. One other note: now that the GNOME code's all fixed, the screen turns on/off as expected for DPMS suspend (as set in the Power Management preferences). Closing the lid still causes nothing to get drawn, though. Re comment #3 - no, it's not something that happens over a long period of time. I can close the lid, count to three, and reopen it and the screen will be dead. Any clues about how I could debug this further would be greatly appreciated. I have the same problem on a DELL inspiron 640m (same graphic card) Things are getting better (on my x61). Now after closing/opening the lid *twice* the screen will come back. The first time it's blank. 2.6.30-rc5-00096-ga4d7749 xorg-x11-drv-intel-2.7.0-4.fc11.x86_64 I get one of the these messages every lid close/open cycle. ... [drm] LVDS-8: set mode 1a [drm] LVDS-8: set mode 1b [drm] LVDS-8: set mode 1c [drm] LVDS-8: set mode 1d Of course I can't seen the first one until I perform the cycle again. At least I don't have to reboot now! I haven't seen others report this but even when the display was blank I could at least switch to another virtual console and log in in text mode. FWIW, I also get these on startup. I'm not sure if they are related.

Created attachment 335022 [details] Xorg.0.log from Thinkpad T43 If I close the lid on my ThinkPad (i915GM chipset), when I open it again the screen is black (with the backlight still on). Same thing happens if I turn the screen off using xrandr / gnome-display-properties - if I try to re-enable the display, it never comes on. Keyboard still works, but VT switch does nothing. I can ssh in and check logs, but there's nothing interesting in Xorg.0.log or syslog. Curiously, suspend/resume work fine - so when this happens, I can suspend my machine and the display comes back on resume. This also doesn't happen if I'm running with 'nomodeset'. Attaching Xorg.0.log, so mcepl won't yell at me :D
