I just realized that I cannot remote connect (SSH) to 2 different systems running openSUSE 11.3 and launch GUI apps like kate or kwrite or konqueror. See below:
P.C.A running openSUSE 11.2 64bit. (local log in). Lets called it Alpha
P.C.B running openSUSE 11.3 64bit. Lets called it Bravo
P.C.C running openSUSE 11.3 64bit. Lets called it Charlie
Local login in to Alpha, open konsole, then ssh -X Bravo -l root
Then type/launch “kate” or “konqueror”, it can launch.
Then from Alpha, open another konsole and type ssh -X Charlie -l root
Then type/launch “kate” or “konqueror”, application refused to run and I get this:
Charlie:~ # kate
kate(19131): Session bus not found
KCrash: Application ‘kate’ crashing…
Warning: connect() failed: : No such file or directory
KCrash cannot reach kdeinit, launching directly.
drkonqi(19133): Session bus not found
When I closed the SSH connection to Bravo, and then type “kate” or “konqueror”, I can launch on Charlie’s ssh connection.
If I connect Charlie 1st followed by Bravo, then Charlie can launch but Bravo cannot launch.
This situation do not happen on the previous version of openSUSE (11.2, 11.1, 11 and so on)
