Simply type in and run kded4 from a konsole window or krunner.
Just tried it here; it works (from either).
Alternatively, Ctrl-Alt-Fx (where Fx denotes one of the function keys, F1-
Fwhatever) and run it from a text login, but you'll have to set DISPLAY
appropriately first, or it won't be able to contact X and find the still
running kde instance.
For this purpose it's useful to know what your DISPLAY variable is set
to, BEFORE you have a problem where you need to know it, so you can set
it appropriately in a text login. Type this in a konsole window and note
env | grep DISPLAY
The output I get here is:
Then, kded4 --help-qt mentions the --display switch, and this works from
a text login, as long as X/KDE is running on a different VT:
kded4 --display :0
Or equivalently, set the DISPLAY variable as part of the command (this is
with bash, but I think any POSIX compatible shell should support it):
FWIW, knowing your DISPLAY setting should allow you to start nearly any X-
based program from a text login, with it then running on the X session
associated with that DISPLAY setting. So for instance I can run kpat
from a text login like so:
