For anyone in the future trying to figure this out, thought I'd post.
Turned out that the "default" xstartup that I thought was explicitly
calling gnome was not doing so, and was calling the system default
desktop instead. Once I explicitly called gnome via a gnome-session
script call in xstartup, the problem was resolved.
Although a great many of the online instructions for setting gnome as
your vnc desktop tell you to unset some variables and then call startx,
all that does is call the system default desktop, which is fine and
dandy if you're running gdm as your manager, but completely worthless if
you are running kdm. You need to explicitly call gnome-session instead
of startx, and you can also dump everything else in the "default" file
as it is not necessary. A functional xstartup can be as barren as:
(gnome)
#!/bin/sh
gnome-session &
(kde)
#!/bin/sh
startkde &
Hope this helps someone in the future :D
Thanks!
