# Wizard to configure a CachyOS (KDE Plasma + plasma-login-manager) install
|
|
# to always boot into a Steam Deck-style gamescope session, with the
|
|
# ability to switch to Plasma desktop and back, Deck-style, and have it
|
|
# reset to gamescope on the next boot/logout.
|
|
#
|
|
# Covers three real bugs found on CachyOS as of Sep 2026:
|
|
# 1. steam-set-session never writes User= to plasmalogin's autologin
|
|
# config, so plasma-login-manager never actually autologs in.
|
|
# 2. steam-set-session fails outright if /etc/plasmalogin.conf.d is
|
|
# missing, breaking "Switch to Desktop" from inside gamescope.
|
|
# 3. /etc/plasmalogin.conf (the base config) hardcodes Session=plasma
|
|
# and takes priority over anything written to
|
|
# /etc/plasmalogin.conf.d/*.conf, so session switches never stick
|
|
# without a bridge that copies the conf.d value back into the base
|
|
# file, plus Relogin=true so ending a session re-triggers autologin
|
|
# instead of dropping to the greeter.
|
|
#
|
|
# Safe to re-run: it is idempotent and backs up files before editing.
|
|
#
|
|
# Automatically configures a permanent background systemd autostart for Steam
|
|
# and Wayland overrides so the Steam Controller virtual keyboard (Steam+X)
|
|
# always works in desktop mode.
|
|
#
|
|
# Optionally also offers to install the official Valve "Vapor" KDE Plasma
|
|
# theme (colors, icons, wallpapers, Plasma look-and-feel package) used on
|
|
# real SteamOS, pulled directly from Valve's own package mirror, so the
|
|
# desktop side matches the gamescope side visually.
