After an extended period of inactivity - say a couple of hours - I find that my MDK9.1 setup won't wake up. I have a black screen with white cursor, but I can't get back to the desktop. Hitting the "Wake" key, which does the trick with the same PC when running Windo$e, doesn't do anything in Linux. I have to resort to bringing up a command line prompt using Ctrl+Alt+F1, login as root, and shutdown -r now.
Any suggestions how I can get this slumbering giant to wake up normally
I don't think you need to shutdown your computer. Go to a command prompt, login , become root,and then do
service dm status
If you get 'stopped' then what happened is that X somehow crashed. You can restart it by
service dm start
It's not a solution - I have no clue why X would shutdown, maybe it helps disable screensaver and powersavings settings for the monitor in kde control center? - but it's at least quicker than a reboot.
Thanks for the tips, quatsch - I'll check out the screensaver and power-saving settings. If that don't fixim, I'll try out the service dm suggestion next time.
