Why didn't it work? What error message did you get?

If you want to connect to X as a different user, you should set the
XAUTHORITY variable to point to the .Xauthority file of the X user
(home/<user>/.Xauthority), and make sure that the user has access
permissions (which is usually the case in acpi scripts, as they are run
as root).
