Some time ago I started having weird problems when closing my laptop's lid for more than 2-3 seconds. I first encountered it while using xorg-server-1.7.7 after downgrading from 1.8.0 (because of other graphics bugs). After closing the lid and opening it a while later (it doesn't happen when I do it very quickly) the screen flashes a few times and goes blank (the backlight is disabled too). After switching to another terminal and returning to X, the screen sometimes goes back again. By then plasma-desktop has crashed and KDE is displaying two dialog boxes saying that I have connected another monitor and asking if I want co configure it. After closing them and manually restarting plasma I can continue work. At the same time the system log is flooded with errors like this: May 14 23:15:33 laptop2 kernel: [ 700.567083] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...

Now after opening the lid I can see for a while the desktop without the plasma shell and the mentioned dialog boxes, the screen flashes a few times, and then the server crashes.

Take a look at this thread, it sounds like your problems could be a symptom of this bug in i915 drm module when dealing with lid events http://www.linuxquestions.org/questions/slackware-14/screen-not-useable-after-laptop-lid-closed-808356/
It surely looks just like my problem, but commenting out those two lines and recompiling kernel didn't help anything. It seems like the errors from system log are gone (or I simply hadn't encountered them yet). plasma-desktop still crashes and I still get the two dialog boxes about connecting a new monitor. Sometimes the whole server just hungs up. I also noticed that I don't get any of those problems outside of KDE (I checked it in kdm login prompt and in fluxbox).
Does this problem still exists?
Yes, also in kernel 2.6.34.
I also noticed, that plasma-desktop doesn't exactly crash: it simply quits and returns 0. The whole output from start to "crash": piotrek@laptop2 ~ $ plasma-desktop --nofork QDBusObjectPath: invalid path "" Connecting to deprecated signal QDBusConnectionInterface::serviceOwnerChanged(QString,QString,QString) QGraphicsLinearLayout::removeAt: invalid index 0 plasma-desktop(2577)/kdecore (KLibrary) kde4Factory: The library "/usr/lib64/kde4/solid_hal_power.so" does not offer a qt_plugin_instance function.

Could you try with a 2.6.35_rc kernel?
It looks like some recent update fixed the issue. I suspect KDE 4.4.5. I'm closing the bug now, will reopen if I'll have more problems with this.
Yup, it was a KDE bug. https://bugs.kde.org/show_bug.cgi?id=236869
