An extra screen detected

DarkSun · 2019-08-05 06:49:38

Hello
I just installed a brand new Archlinux on my friend's laptop
It's a Dell Inspiron N5110

Installed everything without modifying, Installed XFCE as DE
Now it's detecting another monitor/screen in the XFCE's display settings
Main laptop's monitor and another one named CRT-0
I am able to disable them from XFCE's display settings, when I disable laptop's display, The laptop's display goes off, when I disable CRT-0, nothing really happens
But it's limiting the main laptop's resolution since it's set to duplicate the screens
Both xf86-video-intel and nvidia-390xx drivers are installed
Using linux kernel, not the LTS version

How can I remove this second useless screen?
What more information are needed to provide?

Both xf86-video-intel and nvidia-390xx drivers are installed

So this is an optimus system? How did you configure it? (If the answer is "huh, what??" read up https://wiki.archlinux.org/index.php/Optimus )

Yes it is, I disabled Nvidia on boot using BBSwitch, I use Nvidia-Xrun to use Nvidia, The "CRT-0" screen is available on both

Please post the xorg logs of the intel server, the nvidia server as well as complete "xrandr -q" and "xrandr --listproviders" on both servers.
Do you by any chance run xrandr --setprovideroutputsource/setprovideroffloadsink anywhere?
