The error CHANGED on the VM: 'no polkit agent' -> 'access denied by
policy' — the agent unit works; polkit now denies because the user is
not in the libvirt group (fresh run without picking QEMU from the menu,
or no re-login after the pick).
install_session_prereqs now adds the user to the libvirt group whenever
libvirt is installed (idempotent via id -nG check), decoupled from the
advanced-menu choice. Applies after re-login.
Second VM failure: Fedora's polkit-kde .desktop carries
X-systemd-skip=true (and OnlyShowIn on some versions), so niri's
xdg-desktop-autostart.target skips the agent regardless — package
installed, agent dead, same error.
Stop fighting .desktop semantics: install a polkit-agent.service USER
unit (WantedBy=graphical-session.target, which niri/Hyprland/Mango all
bring up) with the Fedora kf6 binary path, pre-linked into
graphical-session.target.wants. Idempotent on both file and symlink.
The VM error persisted with polkit-kde installed: the package's autostart
.desktop carries OnlyShowIn=KDE;, so XDG autostart (which niri honors via
xdg-desktop-autostart.target) skips the agent in a niri session. Package
present, agent never running — exactly the observed behavior.
install_session_prereqs now rewrites the .desktop without the OnlyShowIn
line in place (idempotent: only rewrites when the line is present).
VM run failed: 'No match for argument: polkit-gnome'. polkit-gnome is
orphaned in Fedora (EPEL9 only). polkit-kde 6.6.4 is in F44 and ships its
agent's /etc/xdg/autostart .desktop itself, so the manual symlink wiring
is gone too — installing the package is the whole fix.
virt-manager on niri/Noctalia failed with 'authentication unavailable:
no polkit agent available to authenticate action org.libvirt.unix.manage'
- bare compositors ship no polkit agent, unlike GNOME/KDE.
Two fixes:
- install_session_prereqs installs polkit-gnome and wires its agent
.desktop into /etc/xdg/autostart (paths overridable for testing).
- niri module optionally installs the qemu/libvirt stack, enables
libvirtd, and adds the user to the libvirt group: members manage
qemu:///system with no polkit prompt at all (the real fix; applies
after re-login).
- 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.
Splits setup.sh into lib/common.sh, lib/session.sh and seven modules
(3 DE, 4 TWM). Targets a bare Fedora 44+ install.
Fixes carried over from the first build:
- DEBUG_MODE was unbound under set -u, aborting the script at the version banner
- mangled 'echohttps://...' line left over from the starburst split
- set -e was missing entirely; --debug flag parsing restored
- unguarded 'clear' aborted the run without TERM
- $PRETTY_NAME unguarded under set -u
- modules were sourced, leaking shell options into the parent
- Flathub added twice (system-wide + per-user)
- no dnf5-plugins check before using 'dnf config-manager'
- no Fedora release gate
- /usr/share/xsessions assumed to exist when writing session entries
