# Session manager To be able to run a graphical enviroment it's necessary to run a seat and session manager. It's recommended to use `seatd` in conjunction with `pam_rundir` for a minimal setup: ``` # apk add seatd pam-rundir # rc-update add seatd default ``` Then make sure `pam_rundir` exports `XDG_RUNTIME_DIR` by uncommenting its line in `/etc/pam.d/base-session`: ``` session optional pam_rundir.so ``` For any user to launch a graphical session they must be in the `seat` group. Add them with: ``` # addgroup seat ```
