Screen Saver
If your screen won't unblank after overnight, log in remotely and try this command:
dbus-send --session --dest=org.gnome.ScreenSaver --type=method_call --print-reply --reply-timeout=20000 /org/gnome/ScreenSaver org.gnome.ScreenSaver.SetActive boolean:false
If that doesn't work, this will, but will kill your current session (and everything running) and start a new one:
for x in `ps -aef | grep gnome | awk '{print $2}'` ; do kill -HUP $x ; done
dbus-send --session --dest=org.gnome.ScreenSaver --type=method_call --print-reply --reply-timeout=20000 /org/gnome/ScreenSaver org.gnome.ScreenSaver.SetActive boolean:false
If that doesn't work, this will, but will kill your current session (and everything running) and start a new one:
