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?

    hm, maybe you need another event type. What GPU is it?

    Events:
        access          file or directory contents were read
        modify          file or directory contents were written
        attrib          file or directory attributes changed
        close_write     file or directory closed, after being opened in
                        writeable mode
        close_nowrite   file or directory closed, after being opened in
                        read-only mode
        close           file or directory closed, regardless of read/write mode
        open            file or directory opened
        moved_to        file or directory moved to watched directory
        moved_from      file or directory moved from watched directory
        move            file or directory moved to or from watched directory
        move_self               A watched file or directory was moved.
        create          file or directory created within watched directory
        delete          file or directory deleted within watched directory
        delete_self     file or directory was deleted
        unmount         file system containing file or directory unmounted

    May be create or delete
