Hi,
$ ssh -X -i ~/.ssh/mykey-key.rsa -l gary remotehost -p 1024 [gary@fedora ~]$ evolution (evolution:3644): GLib-GIO-WARNING **: 09:41:05.182: Your application did not unregister from D-Bus before destruction. Consider using g_application_run().
That's not failing unless it comes back to the prompt. How long did you wait? Is it already running for that user?
I now have his PC with me on my local network, and commands executed through ssh -X still display on his screen instead of mine.
From his gnome-terminal on my PC: [gary@fedora ~]$ echo $DISPLAY localhost:10.0
How do I set the display for commands executed remotely to appear on my screen?
