The way I use vnc is precisely to help the remote user in sorting out problems
on their machine (so I need a shared X session so both the remote user and I can
see the same desktop) and in particular problems that can only be done on the
desktop itself - such as changing menus or taskbars etc or settings in KDE. This
always used to work in FC5 and earlier.

I have already entered a BZ for this - at

and also there is possibly a related bug at

I don't need glx for the purpose of this kind of vnc session but once I have
disconnected from the remote machine then the user on that machine would not
have access to glx unless I rebooted without the vnc module loaded in FC6 - this
is a reversion which presumably has crept in with the automatic enabling of DRI
in FC6?  Therefore we have gained something with the new 3-d stuff but lost
somthing along the way for an important tool (vnc).

This really does need to be fixed and hopefully sooner rather than later.
