Hello! :wave:

I just setup Manjaro in dualboot with Windows, and I have a problem with my secondary monitor:

When I run “xrandr” the monitor are disconnected, and when I run “nvidia-settings” it shows the secondary monitor but its marked as “disabled”, and unable to change it for “New X screen” :confused:

Here my xrandr:

Hello,

That is only “required” if you want multihead.

That is /etc/X11/mhwd.d/nvidia.conf and you mixed stuff up. Let me clean it up for you:

Since i do not know the exact position of your Monitors in relation to one another, i made it so the secondary is on your right from the primary.

THANKS THANKS THANKS ! It works :smiley:

And thanks I understand how it works, my secondary monitor are at left but I adapted your file for the right position

Thanks for the fast answer ^^
