XServer in Ubuntu 11.04 without monitor connected?

Question

X Window System

Here, in fact, how to force XServer to start with a non-detectable monitor?
For older ones, it was advised to comment out the line about failsafe in gdm.conf, but in 11.04 it is not there anyway ...

Answer 1

This is what helped me in the past.

Answer 2

The need to run X without a monitor is surprising. Maybe it will be enough for you to use Xvbf ?
