Run commands as the currently-active X11 user
Usage: xuserrun [arg1 arg2 ...]
- systemd
- coreutils
This uses loginctl to determine the active session. If it is an X11 session,
then the display and username are obtained from loginctl. command and all
additional arguments are executed after switching to the active user and
setting the DISPLAY variable appropriately.
On arch-linux, ACPI events are handled by /etc/acpid/handler.sh, which runs as root. To send notifications the the current user, add a line to this script like:
/path/to/xuserrun notify-send "AC Adapter" "Plugged in"
This currently assumes that the user is on the default loginctl 'seat', and will need to be modified if you require multi-seat support (see Multi-Seat on Linux for more information).
