I killed KDE's plasma-desktop on a openSUSE 11.2 machine, because it was eating too much CPU. How can I restart it via SSH or another tty session? On the affected computer there is only shown a blinking cursor on the screen, but I cannot type anything.

If I try "kstart plasma-desktop" over SSH the error message of course is "kstart: cannot connect to X server", because I haven't enabled X11-forwarding. But nevertheless "kstart plasma-desktop" is not the completely correct, because I want to start plasma-desktop on a desktop session and not over SSH on my computer.

I hope I have been somewhat clear. I am looking forward to your help!

You have to set the DISPLAY variable, first. Most likely, your X server runs on display 0, so this one should work:

$ export DISPLAY=:0.0
$ kstart plasma-desktop

Hm, I tried this, but it tells me: "kstart: cannot connect to X server :0.0" – K B Jan 12 at 11:09
Is X server running on any display? If not, run one. – choroba Jan 12 at 13:18
@KB you can start one with $ X :0 – artistoex Jan 12 at 19:04
