http://bugzilla.opensuse.org/show_bug.cgi?id=1008105 Bug ID: 1008105 Summary: parallel kde sessions do not work Classification: openSUSE Product: openSUSE Distribution Version: Leap 42.1 Hardware: x86-64 OS: openSUSE 42.1 Status: NEW Severity: Major Priority: P5 - None Component: KDE Workspace (Plasma) Assignee: opensuse-kde-bugs@opensuse.org Reporter: hiller@mpia-hd.mpg.de QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I have an open kde plasma session on the desktop. So far so good. Now i want to open a second parallel kde plasma 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. Waiting for already running klauncher to exit. Another instance of klauncher is already running! kdeinit5: Communication error with launcher. Exiting! kdeinit5_wrapper: Warning: connect(/run/user/631/kdeinit5__0) failed: : Connection refused Qt: Session management error: networkIdsList argument is NULL Configuring Lock Action XSync seems available and ready XSync Inited Supported, init completed Created alarm 23068673 ksmserver: "/run/user/631/KSMserver" ksmserver: KSMServer: SetAProc_loc: conn 0 , prot= local , file= @/tmp/.ICE-unix/9709 ksmserver: KSMServer: SetAProc_loc: conn 1 , prot= unix , file= /tmp/.ICE-unix/9709 ksmserver: KSMServer::restoreSession "saved at previous logout" startkde: Shutting down... kdeinit5_wrapper: Warning: connect(/run/user/631/kdeinit5__0) failed: : Connection refused Error: Can not contact kdeinit5! 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 plasma to make both sessions work in parallel? Or is there a bug? On opensuse 13.2 and ealier (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 -- You are receiving this mail because: You are on the CC list for the bug.
