OK, I have ran some more tests and this is what I have observed: 1. It doesn't matter whether 'machdep.lidsuspend' is set to 0 or 1 and whether I use the lid or 'zzz' to suspend the laptop - as long as I run 'zzz' or close the lid while on tty (and X is *not* running) and then run 'startx' I *always* get black screen. 2. When the system resumes it always displays the console/ttyC0 with USB resume info - however, I cannot "interact" with console and the key-presses are being passed to the tty I ran 'zzz'/suspended from. 3. I eventually get to see X/cwm after I do a bit of a "dance" - while on ttyC3, 'startx', then Ctrl+Alt+F4 (back onto the tty I ran the command but can be any other tty), back to X (still black) with Ctrl+Alt+F5 and then quit 'cwm' (Ctrl+Alt+Shift+q), after I'm back on a tty running 'startx' brings X/cwm just fine (i.e. the screen is not all black any more. For some reason, backlight/inverter, does not kick in while X starts after suspend, unless I do the Ctrl+Alt+... "dance" described above. Stuart, sorry to piggyback of your initial email - at first, I thought it might be the same thing - now, I'm not so sure. Given the description given here and the info (dmesg and acpidump) in my initial email, shall I still post it to bugs@ again? Cheers, Raf
