Version: (using Devel) Installed from: Compiled sources I have to connect to other PCs often and I am used to rely on ssh -X to automatically set the DISPLAY variable using Xorg's remote window features. When using this on KDE4 apps (eg kate) i get a few messages complaining about missing DBUS connection. When the window appears it behaves extremely sluggish which makes it impossible to use it. .... klauncher(15502) kdemain: No DBUS session-bus found. Check if you have started the DBUS server. kdeinit4: Communication error with launcher. Exiting! kdeinit4: preparing to launch /usr/lib/kde4/libexec/klauncher klauncher(15510) kdemain: No DBUS session-bus found. Check if you have started the DBUS server. kdeinit4: Communication error with launcher. Exiting! kate(15359): couldn't create slave: "Keine Verbindung zu klauncher: Not connected to D-BUS server" .... I know that KDE 4 relies on DBUS for IPC - but could there be a way to re-enable such a basic Unix-Features?
I have the EXACT same problem trying to run a KDE 4 app. I'm using KDE 4.2 in Kubuntu on the machine where I run the app. ssh -X machine ksystemlog & (bunch of brain farts from the application) kdeinit4: preparing to launch /usr/lib/kde4/libexec/klauncher kdeinit4: preparing to launch /usr/bin/kded4 KDE Daemon (kded) already running. kdeinit4: preparing to launch /usr/bin/kbuildsycoca4 kbuildsycoca4 running... ksystemlog(4764) KToolInvocation::klauncher: klauncher not running... launching kdeinit kdeinit4: Shutting down running client. klauncher: Exiting on signal 15 kdeinit4: preparing to launch /usr/lib/kde4/libexec/klauncher kdeinit4: preparing to launch /usr/bin/kded4 KDE Daemon (kded) already running. kdeinit4: preparing to launch /usr/bin/kbuildsycoca4 kbuildsycoca4 running... ksystemlog(4764): couldn't create slave: "No se puede dialogar con klauncher: Not connected to D-Bus server" ksystemlog(4764) KToolInvocation::klauncher: klauncher not running... launching kdeinit kdeinit4: Shutting down running client. klauncher: Exiting on signal 15 kdeinit4: preparing to launch /usr/lib/kde4/libexec/klauncher kdeinit4: preparing to launch /usr/bin/kded4 KDE Daemon (kded) already running. kdeinit4: preparing to launch /usr/bin/kbuildsycoca4 kbuildsycoca4 running... ksystemlog(4764) KToolInvocation::klauncher: klauncher not running... launching kdeinit kdeinit4: Shutting down running client. klauncher: Exiting on signal 15 kdeinit4: preparing to launch /usr/lib/kde4/libexec/klauncher kdeinit4: preparing to launch /usr/bin/kded4 KDE Daemon (kded) already running. kdeinit4: preparing to launch /usr/bin/kbuildsycoca4 kbuildsycoca4 running... ksystemlog(4764): couldn't create slave: "No se puede dialogar con klauncher: Not connected to D-Bus server" *poof* error. The application itself does open (though it sends tens of megabytes of data through the LAN, so it's UNUSABLE). HOWEVER, when any button or menu in the application attempts to open a file open dialog box, the brain fart diarrhea starts again on the console, and after 20 seconds I get an empty file open dialog with a modal error box saying "Could not open slave -- Could not talk to klauncher". What happened to KDE? Doing this was a routine thing in KDE 3, guys. Please confirm this bug, because it is still present today.
Missing DBUS on remote apps is probably not the only reason for slow remote KDE apps. I managed the following to prevent warnings and errors and to increase the speed of remote KDE apps: - X11 forwarding without SSH, but with $DISPLAY and Xauth - starting Dbus, Console-Kit and notification-daemon daemons on the remote site during shell login: e.g. with dbus-launch ck-launch-session sh -c "/usr/lib/notification-daemon; bash" - starting PULSE_AUDIO forwarding e.g. with export PULSE_SERVER=client-pc But in summary I found, that same KDE apps run normal and others are very slow. Examples: Normal: Kwrite, Dolphin, Kaffeine Slow, Xorg CPU intensive: Kate, Amarok It's difficult to debug and to find causes for slowness of each KDE app. Probably tools like Wireshark, Ltrace and Strace can help. Slow apps show a lot of traffic (function calls, network traffic), but this is very low-level information. Unfortunately the application developers are probably not very interested in tuning their apps for remote X11 use.

No response; assuming it was fixed since then.
