Alright so there is some work to do:
- Get a list of packages which are shipped in the edition you want to change to - in this case its BSPWM so head over to our GitLab iso-profiles:
https://gitlab.com/garuda-linux/tools/iso-profiles/-/blob/master/garuda/bspwm/Packages-Desktop
Then install the packages by
sudo pacman -S package1 package2
- Install the matching garuda-*-settings package (forcing you to uninstall the old one) - in this case its
sudo pacman -S garuda-bspwm-settings
- Either delete all dotfiles (often found in ~/.config, ~/.kde4, ~/.profile, etc....) OR you just create a new user account eg. by using KDE settings
- Copy the contents of /etc/skel to your home folder (~/) using Garuda Assistant (at the bottom, apply new configs)
Depending on how experienced or familiar you are with this kind of stuff it might be easier/faster to reinstall though
