If executing "xrandr --auto" works, the following script will automate
the process:
Add a file, say "00_screen", in
/etc/pm/sleep.d/
with the following content:
######################
#!/bin/bash
case "$1" in
thaw|resume)
sleep 5
sudo -u lolc env DISPLAY=:0 /usr/bin/xrandr --auto
;;
*)
;;
esac
#######################
Make the file 00_screen executable, i.e., "chmod +x 00_screen".
