“Cannot talk to klauncher” in Gnome
By chris on March 26th 2008 in /dev/random | 557 views
If, under Ubuntu, you’re running Gnome and you get this error with any of your installed applications (such as Amarok, Quanta, etc.):
Cannot talk to klauncher
this ought to fix the problem:
:~$ dcopserver_shutdown :~$ kdeinit
At least it worked for me.

thanks, this sorted out the klauncher nicely for amarok in gnome in ubuntu 8.04
to get it happening at login add dcopserver and kdeinit as ’startup programs” in Sessions via System > Preferences > Sessions > Startup Programs.
cheers
