Redshift not starting up automatically

[samhh]

User systemd unit is enabled but fails. Running it manually works.

systemd[1014]: redshift.service: Scheduled restart job, restart counter is at 5.
systemd[1014]: Stopped Redshift display colour temperature adjustment.

From journalctl, it tries this a few times:

systemd[1298]: Started Redshift display colour temperature adjustment.
redshift[1304]: Trying location provider `geoclue2'...
redshift[1304]: Using provider `geoclue2'.
redshift[1304]: `RANDR Query Version' returned error -1
redshift[1304]: Initialisation of randr failed.
redshift[1304]: Trying next method...
redshift[1304]: X request failed: XOpenDisplay
redshift[1304]: Initialisation of vidmode failed.
redshift[1304]: Trying next method...
redshift[1304]: No more methods to try.

Possibly fixed by this PR that's merged but not yet in a release: sharpbracket/redshift#753

[samhh]

Probably not, I don't have a graphical-session service. Superceded by #124.
