I've installed fvwm but when i try
fvwm i receive
[FVWM ][main] :<ERROR> can't open display
Do you have the X server running?
You should perhaps change your ~/.xinitrc
The easiest way is probably to install zumi's pdaxrom-fvwm package from
the unstable feed, then remove the link from .xinit to mbession by
rm -f .xinitrc
(make sure that it is still the link, of course ;-))
and link to the fvwm-specific:
ln -s .xinitrc.fvwm .xinitrc
startx should start X with fvwm.
