I have no option in BIOS to change the output sadly :( and, as I don't have Windows...

For now I have tried to rely on reverse prime but it doesn't work because it makes X to crash :S xrandr --setprovideroutputsource nouveau modesetting xrandr --output HDMI-1-1 --auto --above eDP-1 => this causes the crashes and, per bash-completion, I can use DP-1 or HDMI-1-1 apart of eDP-1 as --above argument... but all fail in the same way (as gnome-control-center does when trying to use that HDMI output from it)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
