How to restart alt+f2 dialog in kde after xkill?

The dialog that appears when I press Alt+F2 froze (what is it called? minicli?), I then proceeded to kill it by clicking it after running the command xkill, this was the message:

xkill: killing creator of resource 0x240017b

I then tried restarting plasma-desktop:

killall plasma-desktop
plasma-desktop

Thought this seemed to correctly restart the desktop, it didn't solve the problem since Alt+F2 doesn't launch the launcher.

Solution 1:

The program is called krunner and that's what you have to run:

krunner

Solution 2:

As the user who is logged in, execute the krunner command in background:

rudy@m3800:~/bin$ krunner&
[2] 21108
rudy@m3800:~/bin$ Trying to use rootObject before initialization is completed, whilst using setInitializationDelayed. Forcing completion

Then ALT + F2 or ALT + SPACE should be back.
