Comment # 3 on bug 965653 from andreas bittner

Well the whole desktop was rather semi-reactive and I first wanted to sudo
zypper ref in a simple kterm, nothing else was running on the default kde
desktop.

the command wouldnt execute or print its lines that it was fetching stuff from
the servers so I got impatient and try to cancel it, not much was happening and
suddenly I couldnt even move around a window or make it react.

there wasnt cpu load according to w which eventually executed, and there wasnt
any disk activity ongoing.

So then I decided to kill the desktop, as I have reported about those other
bugs where the xserver and related stuff was hanging because of  dbus and
related stuff, but that bug causes huge cpu load on xorg process. but this
incident is different.

I have no more information on this. Later from alt+f1 i restarted the
display-manager.service and things became normal again after that.

I dont know what processes or parts have been waiting or hanging or why, but
something was wrong.
