Back after some more testing. To summarise: my problem is not related to hybernation or suspension, just closing the lid (or hitting the close lid button) makes the system hang. One funny thing is that the screen goes black (not blank) except for the mouse pointer!
1.) If I plug in a second monitor to the VGA connector, the blanking on lid close is disable, and this problem disappears. Is it possible to forcibly disable the screen blanking even when no external monitor is attached? 2.) I've tried xserver-xorg-video-intel_2.1.1-0ubuntu10~pcjc2.2_i386.deb , but it doesn't help me: my system still lock as soon as I close the lid. 3.) The system hangs even when I'm running only KDM, so it shouldn't be related to Compiz & company.
