cant login, no gui after Selecting more then one desktop during install
What desktop environments?
You would need a display manager enabled and running.
If you are going to use more than one desktop do separate CachyOS installs for each.
Take a look at the wiki. Desktop Environments | CachyOS
During install you can select from many desktops, I picked 2.
What happens is after install I boot to a terminal, as the installer
never asks wich is to be default.
Also SDDM will not remember my last session choice
x11 vs wayland for kde it defaults wayland every time.
Its not suggested to pick 2 different Desktop enviroments and this also gets blocked, but the user can still workaround it.
Last Session:
Report to SDDM.
