Debian without screen

[Jan and Bertil Smark Nilsson <jbsn@tpg.com.au>]

Greetings,

I'm trying to run Debian without a screen. When it has finished 
loading, I get a braille display without any dots. When I check 
/var/log/gdm3/:0.log, it ends with "Fatal server error: no 
screens found". I'm running Sid and the problem occurred after my 
lates software upgrade. The kernel is 2.6.32-5-686. If I boot up 
using kernel 2.31 I end up with "screen not in text mode", but 
the computer seems to have hung. I can't go to any text mode 
console.

Any ideas would be very much appreciated.

Ragards,

Bertil
