KDE Kwin – How to Restart Kwin When It Is Hung

kdekwin

kwin occasionally hangs, which looks like the system not responding to mouse clicks or key presses – although the mouse pointer still moves when you move the mouse!

Best Answer

As described in the official Kwin documentation, a good way to go would be to try this either on a running terminal application or on a virtual console (i.e.: Ctrl+Alt+F1), :

DISPLAY=:0 kwin --replace
