I don't understand whether my computer is sleeping or hibernating or something else. After booting up into a KDE desktop on OpenSuse 13.1, after doing nothing for around ten minutes, the screen goes black.
That's probably the X screen saver. See xset(1).
When I move the mouse the computer "wakes up" a bit and the screen shows the OpenSuse graphic on the right side, and the mouse pointer is responsive, but nothing else is visible or available. There is no dialogue box to enter a password to unlock it, nothing at all.
Can't help there. Try Ctrl+Alt+F1 and back; try sshing in.
If I have a browser or other app open and close the lid, it restores quite well on opening the lid again. What is the difference between the two states, and what config file would I need to look at to resolve the problem above?
Surely closing lid triggers a completely different path, e.g. suspend-to-RAM?
My only solution to date is to CTRL+ALT+F2 su and reboot. Irritating but not the end of the world.
You could restart just X instead. You could look at logs and dmesg and see if any processes are hung. You could even try triggering a suspend-to-RAM and see if the video BIOS tweaks *that* does on restore, are enough to unbugger the video.
