I am running Redhat Enterprise 3, with nvidia accelerated graphics, and am using gnome as the window manager .
When I login as a user I have exclusive access to the graphics device in any terminal window

i.e /dev/nvidia* has permissions rw-------

If I open a xconsole and su to another user account then CFX crashes at startup while trying to access the graphics.
Is there a workaround?

The solution is to chmod /dev/nvidia* to allow access this time, it will be reset when you next login, or modify /etc/security/console.perms to change the default.
