Setup: Ubuntu, Openbox, notebook, occasionally an external screen.
I’ve set things up so that if an external monitor is attached when I start my notebook, a script (run by Openbox’s autostart), xrandr makes that the primary monitor.
What I’d like to do is run that script when I turn off or otherwise disconnect that external monitor, so that I can make the notebook’s built-in screen the primary again. Does anyone here have any ideas how to do that automatically?
Hmm. Maybe I’m doing something wrong but doing
only gives me “No events occurred.” (after ctrl-c stops it). Oddly, I can see the file contents change (connected to disconnected and back again) if I cat it in a separate term window so I don’t know what’s going on.
hm, maybe you need another event type. What GPU is it?
