From the command line you can type: |"sudo xkill"
There's no reason to use sudo for xkill. Root can't do anything with
xkill that you, as the X session owner, cannot do.
xkill doesn't kill an application, it causes the X server to disconnect
the client application. Usually that will cause the application to
exit, but if it's well and truly stuck, it may continue consuming memory
and CPU resources in the background, in which case you'll still need to
track it down and kill it.
