Running a desktop, like anything, requires system resources, but there is no
particular incompatibility with running a "desktop" and *. Given enough
memory
and cpu, expect no problems. In a commercial setting where * is serving as
a corporate PBX, I'd avoid running anything else on the same system, but
for home/hobbyist use, I wouldn't worry about it. I run a dual-display
"destktop"
(XFCE4), various daemons (NFS server, CIFS server, a music server, CUPS),
as well as use the system as a movie and music player, and * works fine.
It's a 2GHz AMD-64, but it never even breaks a sweat.
Also keep in mind that a dependency on a shared object is not the same thing
as a dependency on an executable or daemon. Shared objects and modular
object code are a very good thing.
