[Solved] KDE - closing lid kills plasma-desktop

After from-scratch reinstalling Arch+KDE4.4 with clean config on my HP Compaq Mini 110, I got the following issues:

Even after disabling all powermanagement features I am sometimes presented with a black screen like this after closing and reopening of the lid:

(Notice the "compressed" Firefox top-left. plasma-desktop not running.)
I can sometimes fix this by pressing ALT+F2 and starting plasma-desktop, but sometimes it's just the responsive cursor, but ALT+F2 is not working. I then need to CTRL+ALT+F1 and /etc/rc.d/kdm restart.

BUT: Sometimes everything works, but I get this:

(Basically saying that the "monitor" has been removed (greyed out window) and that a new monitor was found (window in foreground).

Notice, this also happens when I set up powermanagement to "suspend on lid close": I close the lid. It suspends, then I reopen the lid and I am presented with the above screens.

What can I do? How can I disable KDE's automatic monitor detection stuff?

EDIT:

It's definitely a KDE problem: On Openbox everything works fine. It just safely ignores the lid stuff.

Try disabling the "randrmonitor" in System Settings > Advanced > Service Manager.

Note that this is a fault of your graphics drivers, either because they are being removed prior to suspend to workaround missing suspend support, or because they incorrectly handle the display being turned off.
