Re: [Xen-users] Help with VGA passthrough

[Daniel Shub <Daniel.Shub@xxxxxxxxxxxxxxxx>]

What do you mean by a terminal window? Are you on tty7? Can you switch through 
the tty's? You might want to step back and instead of automatically launching 
lightdm, just try and get a tty over vnc without X and then start X and see 
what happens. It seems like you have passed the device through correctly.
