I installed KDE in my “Manjaro” install (more on that later) and it runs mostly ok, except it never asks for password and any application or process that requires root access will fail: Timeshift just blinks on screen and Pamac runs ok until you try to apply updates and changes to packages.
Command line sudo
and other commands that ask for password themselves like trizen
or chsh
work normally.
The problem seemingly stems either from me failing to install/configure KDE correctly or from the fact this “Manjaro” install is an Arch Linux running on WSL transformed into Manjaro. Please, don’t shoot me.
I installed and configured Xvnc over Xrdp to a seemingly working condition and I can access the DE from Windows itself through RDP. Again, it seems to work nicely if not by the auth issue on the desktop environment.
