Hi, With regards to "FN keys", I tried all the FN keys and Ctrl+Alt+FN keys and Esc and many others but nothing worked.
With regards to "never close the lid, but suspend via SW", (1) while in xfce account I ran sudo pm-suspend which suspended the laptop and (2) I then pressed the shift key and the laptop resumed normally with a working display. I repeated this with a remote ssh login into the laptop and it also worked perfectly. With regards to "xset dpms force off", when I do a remote ssh login into the laptop which resumed from wakealarm and has no display, I don't see a DISPLAY environment variable. When I execute "sudo -u bierre env DISPLAY=:0 /usr/bin/xrandr --auto", the system reports: No protocol specified Can't open display :0 I don't know if I am remotely executing this command correctly. Furthermore, I don't know how to reach xorg to execute "xset dpms force off".

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. [Laptop System Information] laptop = MacBookPro5,5 pm-utils version = 1.4.1-13ubuntu0.2 kernel = Linux version 3.19.0-32-generic (buildd@lgw01-43) (gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) ) #37~14.04.1-Ubuntu SMP Thu Oct 22 09:41:40 UTC 2015 OS = "Linux Mint 17.3 Rosa" based on "14.04.3 LTS, Trusty Tahr" desktop environment = XFCE video card = NVIDIA Corporation C79 [GeForce 9400M] (rev b1) (prog-if 00 [VGA controller]) video driver = [633938.944] (II) NOUVEAU(0): Output LVDS-1 [Additional Information] 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 with a normal working display. So the problem of no visible display occurs only when I open the lid after resume from wakealarm and before the backup job suspends the laptop.
