Sorry, I forgot to make a correction to my [Additional Information] which I re-tested. After my cron backup job is finished it will check if the lid is closed. If it is closed then it will run pm-suspend. If I then open the lid, the laptop resumes without a normal working display. So pm-suspend suspended the laptop without a display and the next time I open the lid the laptop resumes without a display.

At 7:30 AM the next day, the laptop resumes from suspend with the lid closed and executes cron jobs (e.g. some backups). If I open the lid then there is no display. I tried several options to resume the display: - [FAILS] all sorts of keyboard combinations - [FAILS] ssh -X into laptop and execute "sudo -u bierre env DISPLAY=:0 /usr/bin/xrandr --auto" (n.b. when I run "sudo -u bierre env" there is no DISPLAY variable) - [MANUAL HACK] closing the lid causes the laptop to suspend and then opening the lid causes it to resume with a normal working display I would like a solution or SOFTWARE HACK which I could add to /usr/lib /pm-utils/sleep.d/99video during resume from suspend triggered by wakealarm so that opening the lid would reveal a working display.
