Any way to resolve the "another window manager is already running" error with dwm in OS X?

Question

I know it should be possible to run dwm in OSX Mountain Lion, since it is possible to run X11 (or xQuartz). However, whenever I try to run dwm I just get

dwm: another window manager is already running

in the terminal and it fails to start. Any suggestions?

Answer 1

killall quartz-wm

If it kills the whole X session (because wm was last line in the init script), modify your .Xinitrc script and replace quartz-wm with dwm

Answer 2

Just paste the following into ~/.xinitrc.d/00-dwm.sh:

USERWM=/usr/local/bin/dwm

And make the file executable (chmod +x).
