People have asked how to disable the screen from going blank or to sleep, but I have a slightly different question. I would like to be able to remotely wake a sleeping or blank display, but then allow it to go blank again. So far this isn't working.
export DISPLAY=:0 in my .bashrc file and, when the screen goes blank, I run
xset s reset over SSH. What I've noticed is that the screen "wakes up", but that it will never go blank again. I'd like to re-enable the default behavior after calling the reset command. Should I just set up the timeout again or is there a different way I should be waking the display? I'm just curious why reset changes the behavior.
