First, if you have a caps-lock led or other identifier, try turning caps-lock on and off. If it switches on and off, the box is not locked, only X is totally black (including the cursor - which is not usually the case). In that case, try control-alt-backspace, twice. control-alt-backspace, not control-alt-delete. that should kill X and restart it. Another thing to try would be control-alt-f2 (or f3, f4, f5, f6) to go to a text console. If that works, you can log in and see if you can figure out what might be wrong, and ultimately switch back to X (alt-f7) and reset it (as above).
I have this problem a *lot* on my laptop with KDE4 and desktop effects (compositing), using the NVidia drivers, but I have a cursor. in my case it is a bug in (probably) KDE4 or the NVidia drivers. Yours may be a different issue.
Consider turning off desktop effects (if you have them enabled) and see if the problem comes back.
Just some things to consider.
In my case no keyboard-key works, restarting the desktop by ctrl+alt+bckspcx2 is not an option, nor ctrl+alt+del.... I had these effects turned off allready, as i thought it had something to do with the freezing when choosing a screensaver, but wether 'off' or 'on' made no difference.... I have this on another machine also, with all versions from the start, but not consistant... there is really no telling when, why or how this happens..(locking up of desktop in 'black-phase') As now with this newly installed box, tried about 4 times to activate after a long time off 'waiting', as i am doing all kind off things, on different machines, but all these 4 times the desktop responded normal..... It is not nice to get things you cannot lay your finger on....especialy in a released version.. In alpha's or beta's, or milestones as they are called now, you can expect all kinds of misschief, as sometimes too many things change at once.... Still i wounder if these are related.. You say your cursor is still there... On one of my other boxes, 64bit, it happens that sometimes the freezing happens during the screensaver...so there is no visual cursor at that time.. It happened here also after the screen goes black, when it has to go into screensaver (if it was possible to choose one without locking up), or beyond.... -- Enjoy your time around, Oddball (M9.)
