No, nothing special I am aware of. Symptoms are very strange.
Once logged in, I can see some active process of xscreensaver (this is what
"pidof xscreensaver" tells me).
But after some seconds, this process is gone. Why? Don't know.
And I see another process, what is this?
2884 0.0 0.0 5716 1064 ? SN 01:13 0:00 xscreensaver-systemd
The manpage of this binary is slightly confusing. That is some kind of
helper, fine, but who is supposed to run it? Xsession? Or systemd user
session? It mentions "When run from ~/.xsession or equivalent" but there
is no information on what is considered "equivalent" here.
Anyway, I patched /usr/lib/systemd/user/xscreensaver.service to add your
instructions:
$ cat /usr/lib/systemd/user/xscreensaver.service
[Unit]
Description=XScreenSaver
[Service]
#ExecStart=xscreensaver
ExecStart=/bin/sh -c "printenv ; pwd ; xdpyinfo ; xscreensaver"
[Install]
WantedBy=default.target
I did daemon-reload (for --user). Net result: no visible change but the
state is this now:
$ systemctl --user status xscreensaver.service
● xscreensaver.service - XScreenSaver
Loaded: loaded (/usr/lib/systemd/user/xscreensaver.service; enabled;
vendor preset: enabled)
Active: inactive (dead)
Dez 30 01:13:20 whitestar systemd[2605]: xscreensaver.service: Service has more
than one ExecStart= setting, which is only allowed for Type=oneshot services.
Refusing.
Dez 30 01:13:20 whitestar systemd[2605]: xscreensaver.service: Cannot add
dependency job, ignoring: Unit xscreensaver.service has a bad unit file setting.
Now this does not make any sense anymore.
Best regards,
Eduard.
