No. If you want to use DeMuDi, then install
AGNULA/DeMuDi. You are asking for
trouble if you try to install it backwards like this. The main problem you
are likely to be experiencing with DeMuDi is that it doesn't support
proprietary drivers, so the nVidia support is limited. PlanetCCRMA/Fedora or
Mandrake might be more sympathetic to your hardware.
Uh. That's what I did. And it's completely unusable. So I asked if
there is an alternative way to get the same functionality. According
to Agnula:
"Q: Can I install A/DeMuDi over an existing Debian installation?
A: Yes, at least as long as you are running Sarge. Follow the following steps"

And according to something I read somewhere, Libranet can be used as
an (easy) installer for a normal debian system. You just do a
"minimal install" and then dist-upgrade to testing and all will be
perfectly debian. Or so I read. (And can't find it now.) If another
distro like Mepis can be used the same way, that would be good. I've
tried the debian installer by itself and it was a nightmare.
