I have a samsung laptop screen as the 'built-in' monitor, and it works fine on its own.
When I plugged in a usb-C dell monitor, the main monitor was transferred onto it, while my laptop monitor went blank.
In this state, I tried logging in and out, and restarting. While the UEFI screen was normal, from the login the only screen that works is the external monitors'.
I tried unplugging the monitor, replugging it, but as soon as I plug it in, the system recognizes the external monitor as the main one, and does not show anything on the built-in screen.
The device uses an intel i7 and intel ARC internal graphics. It does not have a graphics card besides that.
The Ubuntu kernel is the most recent one.(6.1.9)
The monitors are coincidentally of very similar size, and the resolution is identical.(1080p)
This is the troubleshooting I've gone through:
- Logout/in, Restart: As above
- Setting > Displays: Only shows one monitor at a time.
- Find
Xorg.conf file: Do not have one. Only have xorg.conf.d
- ctrl+F7, ctrl+F1
- Plugged in an LG HDMI monitor: Does not recognize at all(??)
sudo apt-get update && upgrade- Rotated the external monitor -> Is rotated only when logged in(is it supposed to do that?), retains memory that the external monitor is to be rotated, not the built-in one.
xrandr --listmonitors:
(When unplugged external display)
Monitors: 1
0: +*XWAYLAND9 1920/340x1080/190+0+0 XWAYLAND9
(When plugged in external display)
Monitors: 1
0: +*XWAYLAND10 1920/480x1080/270+0+0 XWAYLAND10
But the monitors were still present on Setting > Appearance and Colors??
(All the above were taken with the external monitor connected)
I am confused.
Any other attempts will be very appreciated.
