Autologin into the gamescope Steam session does not take on the real
hardware; the television lands on ReGreet instead. The config side is
correct -- initial_session is present in the generated greetd.toml and
services.greetd.restart evaluates to false -- so the likely cause is the
session starting and then dying, which greetd answers by falling through
to default_session.
greetd hands a session the VT for its standard streams, so whatever the
session prints on its way down is erased as soon as the greeter repaints.
Run the launcher under systemd-cat so the reason survives in the journal
under the steam-session identifier.
Steam's non-Steam-game Browse dialog and its library-folder picker both
go through the XDG portal FileChooser interface and do not open here
(ValveSoftware/steam-for-linux#9447, #10415). Add steamtinkerlaunch,
which writes shortcuts.vdf without the dialog, and document
library_folder_add as the equivalent route for the library folder.
Docs also catch up with the host's actual state: hardware-configuration
.nix is a real scan now, standalone pcsx2 is installed, and the untested
claims become the list of open problems.
