Comment 5 for bug 350351

Steps to a little bit of headway:

- configure video with xrandr to use only the external VGA (xrandr --output VGA-0 --auto --output LVDS --off)
- suspend with: sudo pm-suspend --quirk-vbe-post
- system goes to sleep
- press a button
- system wakes up
- press ctrl-alt-F7
- the video comes back on

Problems:
- the internal display can't be turned on. I tried xrandr --output LVDS --auto.
- the process "vbetool post" causes 100% cpu load, and has to be terminated
- can't suspend twice: issuing sudo pm-suspend --quirk-vbe-post once more, has same effect as "echo"
