As there was a plasma-desktop crash window every time I log in, I tried to solve the problem by disabling a startup item in the "desktop configurations->start up and shut down->unchecked "plasma workspace".

Now it is a black screen after I log in...

Which configuration file can I edit to enable it again?

BTW it is opensuse 13.2. However I find that there's not this item on my manjaro kde edition.

Thanks.

That's to be expected if plasma is not started...

You should still be able to reach KRunner via Alt+F2 and run "systemsettings" (or "systemsettings5" if you run Plasma5) to reenable it.

Or have a look in ~/.config/autostart/, you should find a plasma .desktop file there I think. Deleting it should make it be started automatically again.

If you mean Plasma, that's not listed in "Startup and Shutdown" here on my openSUSE installation either.
It is normally started via system files in /usr/share/autostart or /etc/xdg/autostart (depending on which version you use).

Thanks. Fixed it by copying the plasma.desktop from /usr/share/autosart to ~/.config/autostart/.

Later I found there are then two plasma.desktop in the autostart list. One is checked (must be the newly copied) and one unchecked. So there must be a config file that controls enable/disable. I just deleted the unchecked one.

The one in /usr/share/autostart/ should be started automatically anyway, unless there is one in ~/.config/autostart/ that overrides it.

And actually, plasma.desktop doesn't start plasma at all, it's plasma-desktop.desktop that does that. As you removed the copy in ~/.config/autostart/ (the one that was "unchecked", i.e. disabled, probably), the system-wide one has effect again and starts plasma-desktop.

I would recommend to delete ~/.config/autostart/plasma.desktop as well though.
