It was no problem to configure/make/make install LightDM 1.16.3. But I'm struggling to get it running. I've snarfed the systemd service definition from the 1.6 RPMs I found, and that works. But lightdm exists after writing this to STDERR (it appears in /var/log/messages, fortunately): Failed to use bus name org.freedesktop.DisplayManager, do you have appropriate permissions? I tried strace-ing, but are only some binary messages being exchanged before this, and I have no idea how to tackle this. I.e. I have not the faintest about DBus. Any ideas or hints how to proceed? <div>Mit freundlichen Grüßen / Kind regards Lupe Christoph im Auftrag von / on behalf of Creative Data AG - Standort Süddeutschland - Otto-Lilienthal-Str. 36 D-71034 Böblingen Mobil: +49 (0) 172 630 1004 E-Mail: <a href="mailto:lchristoph@extern.creativedata.de" target="_blank">lchristoph@extern.creativedata.de</a> Web:<a href="http://www.creative-data.de/" target="_blank">www.creative-data.de</a> Firmensitz: Robert-Bosch Str. 10 D-50769 Köln, DeutschlandSitz der Gesellschaft: Köln, Registergericht Köln, HRB: 45125 Köln Vorstand: Heinz Friebel, Aufsichtsratvorsitzender: Gerhard Böhm</div></div>_______________________________________________ LightDM mailing list <a href="mailto:LightDM@lists.freedesktop.org" target="_blank">LightDM@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/lightdm" rel="noreferrer" target="_blank">http://lists.freedesktop.org/mailman/listinfo/lightdm</a> </blockquote></div>
