Comment # 43 on bug 966671 from Bruno Friedmann

Just adding my experience, during months I didn't know why every application
launched was saying "No protocol specified" storing thousand of them in logs
(journal).

Fabian drive me to the fact that hostname was changed during boot.
I'm using TW (fresh) with NetworkManager and dhcpd, sddm with auto-login.

I've checked and in /etc/hostname I've got my fqdn written down here instead of
shortname.

I used hostnamectl --static set-hostname qt-kt which was now what is written
down in /etc/hostname

I've check it after two reboot, and the name is now stable. (shortname is use)
and I don't have anymore double socket for akonadi, or other.

To be checked : change network (so domain change) and check what happen.

The fqdn source I guess (didn't have anymore the original yast2-log) was setup
during first initial configuration during installation.
