[LightDM] launch xvfb if no monitor detected

[Vojtěch Polášek]

Hi,

I am not sure if this is the right mailing list to ask this but I will 
try. I am creating a Fedora remix for blind and visually impaired users. 
Some of these users have desktop computers without monitors, because 
they simply don't need them.

Unfortunately, this causes a problem because the grahpical environment 
refuses to start at all if no monitor is detected.

Do you think that lightdm can somehow solve this? Or should I solve it 
through some different component?

I would like to use xvfb to simulate the monitor.

Thank you,

Vojta
