It seems that latest X in potato has removed the support for /etc/X11/window-managers in Xsession. So how does one start fvwm95 automatically from xdm ??
In documentation I found just the removal mentioned, but no alternative: * debian/xfree86-common/Xsession: - remove support for /etc/X11/window-managers; virtually every window manager has migrated to the new alternatives method (Closes: #58224) -Igor Mozetic
