You have to be joking me. "A distro that is designed for the WM you want to use"?

What does that even mean? That I have to have a special twm distro? Or an fvwm2 distribution? tvtwm was always my favorite window manager, but I seem to recall it needed some patches to really be perfect. Do I have to find somebody to build me my own distribution that has those patches?

A Window Manager manages windows, like the name suggests; it doesn't manage networking or sound. And if it does, then the whole system has failed to produce decent engineering boundaries and we should revert a few releases to when things had the correct levels of abstraction.
