Bit of playing... From what I can make out, DPMS isn't being set on, or
is being ignored on some boots by the driver.
If I ssh into the laptop (while screen is off) and issue:
#sudo vbetool dpms on
the screen then turns on.
As a quick&dirty fix for this, I did the following:
Edit the file
/et
Exactly the same issue as me, running 11.04 (Natty) on an Aspire 3500.
Boot up, initial boot is a completely blank screen, the only way to get
the screen on is by pressing Ctrl+Alt+F2, then Ctrl+Alt+F7.

prove useful (this is my parents laptop)
