Garuda Arch-based Linux distro
Garuda Linux is popular for offering a stable Arch Linux along with a Time Shift backup utility.
Garuda has used Snapper by default for a long time now, maybe a year and a half or so at least.
Just like other open-source Linux distributions listed here, this one also comes with multiple desktop environments, they are- bspwm, Cinnamon, Deepin, GNOME, i3, KDE Plasma, LXQt, MATE, Recbox, UKUI, Wayfire, Xfce.
BSPWM, Deepin, Recbox, UKUI?!
If you are a beginner then GUI Software for package management (Pamac) is there to install various open-source software with one click.
Pamac? …
To switch between multiple installed GPUs on the Desktop, it has Optimus Manager.
