dwm is a wonderful window manager for X: it's small, fast and stable.
The only thing I missed, until today, was the possibility to restart it without losing my X session (i.e. all the open windows, etc.). Restarting
dwm is something you might need to do often, as it does not have config files: changes are done by recompiling the sources.
The trick is to execute
dwm in background and sleep forever! Take a look at the last two lines of my
dwm & sleeper
sleeper looks like this:
#!/bin/sh while `/bin/true`; do sleep 1000 done
Now, if you kill
dwm (usually with
ALT-SHIFT-q) the windows (and X) will still be alive and you can type
dwm& in any xterm to get
dwm up and running again. If you really want to quit X, you need to kill the sleeper.
