I'm using Xubuntu 12.10 with an Intel mini PC. The video card is Intel HD 4000.
This mini pc has 2 HDMI video outputs. Everything is fine when booting with an HD TV connected, but if I boot without it (HDMI cable disconnected) and then after the boot I connect it I can only get the console login.
The problem is related to this error:
"screen(s) found but none have a usable configuration"
How can I make possible to connect the TV after the boot having X up and running with the latest resolution configured?
Thanks for the support.
