Hi,

maybe, could you ship this unit file as /usr/lib/systemd/user/unclutter.service?
This runs unclutter independent of the window manager and it aggregates
all log messages via journal.

```
[Unit]
Description=Daemon to remove idle cursor image from screen
Documentation=man:unclutter(1)
PartOf=graphical-session.target

[Service]
ExecStart=/usr/bin/unclutter -idle 4 -root

[Install]
WantedBy=graphical-session.target
```

Regards Jörg

Hi Jörg,

Well, /etc/X11/Xsession.d/90unclutter is also independent of the
window manager...

So I assume that -- if we include your file --
/etc/X11/Xsession.d/90unclutter will need to check if its running
under systemd and if it discovers that it is running under systemd,
then do nothing? (BTW: What's the best way to do such a check?)

I'm though not sure if we don't loose some cases where it now would
start and later would not start.

So far that's the only advantage I see of that .service file.

The best way should be checking for the $MANAGERPID (see systemd.exec(5)).
To support non-systemd systems it would be necessary to have the
90unclutter script.

If there's such a check in 90unclutter, it is possible to install the
unit as disabled and run `systemctl --user start unclutter` when systemd
is available.

Another advantage would the possibility to restart unclutter after updates
of system libraries. If it aligns this way, *needrestart* shows the
unclutter unit, when it needs to be restarted after updates.

The systemd unit also provides the easy enforcement of some security
constraints. I didn't check it, but `NoNewPrivileges=true` and
`ProtectHome=read-only` might be working.



Kind regards, Jörg

Thanks for these hints. Will check for the next upload. (A new version
of the unclutter package currently waits in the NEW queue.)

Is needrestart (or needrestart-session) in the meanwhile able to
restart such user services? IIRC needrestart-session could just inform
the user about necessary restarts in a pop up notification.

Good point. Both suggestions look fitting on a first glance. Will
check.
