Bug ID: 371977
Summary: parallel kde plasma5 sessions do not work
Product: plasmashell
Version: 5.5.4
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: hil...@mpia-hd.mpg.de
CC: bhus...@gmail.com, plasma-b...@kde.org
Target Milestone: 1.0
I have an open kde plasma5 session on the desktop. So far so good. Now i want
to open a second parallel kde plasma5 session, e.g. with nomachine's nx. That
fails with the message:
Loading stage "initial" 64
startkde: Starting up...
kdeinit5: preparing to launch 'libkdeinit5_klauncher'
kdeinit5: Launched KLauncher, pid = 9707, result = 0
Waiting for already running klauncher to exit.

Another instance of klauncher is already running!

startkde: Done.
Qt: Session management error: Could not open network socket
The X11 connection broke (error 1). Did the X11 server die?
The rason is that the first kde plasma session has opened the socket
/run/user/631/kdeinit5__0 (631 is my uid), and the second kde plasma from nx
wants to open the same, which is already blocked by the first session. Closing
the first kde plasma makes the nx work.
A workaround would be using another window manager for the second session.
Is there a trick withing kde plasma5 to make both sessions work in parallel? Or
is there a bug?
Plasma 4 this never was a problem, because in /run/user/631/ksocket-ulrich/
there were in such cases two sockets opened, e.g.: kdeinit4__0 and
kdeinit4_nx.mpia-hd.mpg.de_516
With kind regards, ulrich
