- XFCE module installs/enables sddm instead of lightdm; one greeter across every session choice, no lightdm left anywhere. - Interactive menus now default to 'none' for both DE and TWM (press Enter for no DE / no TWM). none+none is still refused by the existing guard. - README and session.sh comments updated to match.

setup.sh — unified Fedora configuration (Fedora 44+)
|
|
|
|
Usage:
|
|
./setup.sh interactive: pick a DE and a TWM
|
|
./setup.sh --de=none --twm=niri non-interactive, explicit choices
|
|
./setup.sh --debug pause after each section
|
|
|
|
Options:
|
|
--de=NAME gnome | plasma | xfce | none
|
|
--twm=NAME chadwm | hyprland | mango | niri | none
|
|
-y, --yes never prompt (requires --de and --twm)
|
|
-d, --debug pause after each section instead of aborting on error
|
|
-h, --help show this help
|
|
|
|
Valid DE/TWM combinations:
|
|
any DE + any TWM DE provides the session, TWM is added alongside it
|
|
none + any TWM TWM-only machine, SDDM is installed as the greeter
|
|
any DE + none plain desktop, no tiling window manager
|
|
none + none refused: that is not a graphical system
|
|
|
|
Notes:
|
|
* chadwm is an X11 window manager; the other three are Wayland compositors.
|
|
* Run as your normal user, not root. sudo is used where needed.
