Ive installed Ubuntu on a notebook with a broken display with the help of an external monitor. When booting, the external monitor shows everything fine, but when the login appears, it stops output to the monitor.
It seems that I can configure my outputs through xrandr, but I cannot see anything happening and I cannot also even check if the console is open to accept commands (tried ctrl alt T).
I have also tried xrandr --output VGA1 --auto from another question posted here, but nothing seemed to happen (tried with VGA1, VGA0, VGA-1 and VGA-0 too).
Does anyone have any idea how to work this around?
