Package: xbase Version: 3.1.2-9 The /etc/X11/window-managers file constructed by xbase.postinst contains fvwm but omits fvwm2. This is somewhat disconcerting if the fvwm2 package is installed, but not the fvwm package. Another option would be for the fvwm2 package's installation scripts to add an appropriate entry to /etc/X11/window-managers
