# Shared settings for the two sessions on the Steam Frame, and the
|
|
# user-services mechanism.
|
|
#
|
|
# The Frame runs the Steam/VR session (gamescope, systemd user manager, outer
|
|
# D-Bus at <runtimeDir>/bus) and a nested Plasma desktop with its own
|
|
# XDG_RUNTIME_DIR and private D-Bus. Modules that talk to the outer session use
|
|
# `runtimeDir` / `userBus` explicitly.
|
|
#
|
|
# User services: `home-manager switch` usually runs from the nested desktop,
|
|
# whose XDG_RUNTIME_DIR and D-Bus can't reach the user manager, so
|
|
# home-manager's own reloadSystemd step is skipped ("User systemd daemon not
|
|
# running"). The `steamFrameUserServices` activation entry does it instead,
|
|
# pointed at the outer session: it always runs `systemctl --user
|
|
# daemon-reload` (so changed unit files are picked up even when both lists are
|
|
# empty), then starts the units in `userServices.start` and restarts those in
|
|
# `userServices.restart`.
