Description Fuminobu Takeyama 2024-03-20 05:44:25 UTC 
I have an external monitor connected to my laptop. Display and Monitor recognizes all the monitors and I can change resolutions, scale, etc.

However it does not show the external monitor in "Drag screens to re-arrange them" area and I cannot adjust the screen layout.

See a screen shot attached.

Sorry, this problem is not related to Wayland and happens even on X11. It seems that this happens only with a specific monitor.
