I have the same problem as Leonardo:
"X gets stuck after resuming from screensaver, after a log period of inactivity
(no keyb/mouse input), mostly after a night long. Ctrl+F2, Ctrl+Alt+Backspace
and Ctrl+Alt+Del don't help. "
But, it is on an old asus motherboard running Kubuntu - intrepid:
Host bridge: Silicon Integrated Systems [SiS] 645xx (rev 51)
VGA compatible controller: ATI Technologies Inc RV280 [Radeon 9200 SE] (rev 01]
I cannot get in touch with the system except through ssh, from where I
have succeeded in killing kdm and X with kill -9 (kill -15 did no do the
job). But, nevertheless, nothing happens when I Ctrl+Alt+Fx at the PC.
Having stopped klog and dbus, too, I was able to restart by
Ctrl+Alt+Del. But else, it doesn't look like I could communite with the
PC except through ssh (which seems to work perfectly).
I have a suspicion: There are a number of power management function in
the BIOS, which I have turned on. Among other things, there is a screen
suspend function. Perhaps intrepid don't cope with this? (I notice that
Leonardo writes: "mostly after a night long"). Well, I disable all this
stuff, and you will hear tomorrow, if it helps. (Incidentally, when
intrepid shuts down, it doesn't switch off the hardware.)
