[X2Go-User] Frozen Login Screen "kscreenlocker_greet"

[Ulrich Sibiller]

I have seen similar behaviour on Centos, also with kde. It seems that
plasma-desktop is running wild. You can probably mitigate the problem
a bit by adding this to /etc/x2go/x2goagent.options
X2GO_NXOPTIONS="sleep=0"

You can also try to kill and restart the plasma-desktop but at the
moment I do not remember how that can be done. Try to search for the
process that takes up all the cpu and google it.
