I am struggling to think of any scenario under which VirtualGL would work properly inside of TurboVNC but deliver that error outside of TurboVNC. That error typically means one of the following:
(1) You haven't run vglserver_config, so the 3D X server will not allow access while it's sitting at the login prompt. (2) You ran vglserver_config and configured the system such that only users of the vglusers group can access the 3D X server, but you forgot to add yourself to the vglusers group-- or you didn't log out and back in so the new group permissions could take effect. (3) There is no X server running on display :0 (but if you are able to successfully use the system from within TurboVNC, then this must not be the case.) Are you 100% sure that nothing has changed between the two tests? Maybe you left the machine logged in for one test, so access to display :0 worked, but you logged out of it before running the other test, so access to display :0 no longer worked? Grasping at straws here. You might also try removing ~/.Xauthority as a last-ditch effort. Perhaps it's corrupted somehow.
