i recently installed Manjaro KDE/Plasma on my xps 15 and there are a couple of issues I wanted to request help from the community on. (I am a noob on Linux so please excuse me if i incorrectly refer to certain components)
I am using Plasma on Wayland since this is the best / easiest option I came up with that supports mixed DPI configuration (4K laptop - 200% scaling , and external monitor - 100% scaling). I tried Wayland on Ubuntu's default Gnome but not all apps (including firefox) would scale correctly when moving from one desktop / screen to the other. surprisingly works really well on Plasma.
the issue I have is:
- as per the screenshot below in the 'Display configuration' Dialog, there is no option to 'set as Primary' display option. IF i recall correctly, on the live USB (installer) the option was appearing under the marked 'Enabled' Option
- I have to disable the Laptop display to get the external monitor get assigned as the primary display (re-enabling laptop after wards behaves as a secondary display). Every time I restart the machine the display configuration is reset and laptop display again becomes the primary display.
Any pointers/suggestions on how to fix this will be highly appreciated.
