--- Comment #13 from Simon Herrmann
First thing you can try is run
xrandr --auto
This should enable the external monitor. Afterwards please attach again the output of 'xrandr' and tell me, whether this enabled the external monitor.
Then I don't know which kind of screen/monitor layout you want. It could be established via command line tool
xrandr
using appropriate options, but also with tool your desktop is preferring. No idea, which desktop you're using though.
BTW, most likely the desktop was confused by the strange monitor layout (internal display having a different and even bigger resolution than the external one), made some unlucky/wrong assumptions and failed completely in the end.
I am using Gnome, if that's what you mean by 'which desktop'. The monitor is BENQ 2400 Eco (FullHD). -- You are receiving this mail because: You are on the CC list for the bug.
