I have two machines, both running kubuntu: server & client. I'd like to connect to server from client and start the full graphical interface without fear that some commands would be run as client user.
ssh -XC works and I can also start graphical programs from it just fine.
However, when I type
startkde in the ssh console, it says "KDE seems to be already running on this display." Which is true, but not for the same user account.
I tried exiting graphical interface and logging in from tty, but that then (unsurprisingly) failed to start any graphical programs, including kde.
How then can I do this such that I could simply log in just as I log in with a local user? Use client machine as a dumb terminal.
