First the Cone example is supposed to close the window after animation 
is displayed. If you see a rotating cone on the  screen before window 
closes. The example works fine.

The "...XFree86-DRI..." message is more of a warning then an error and 
is most likely not related to VTK. I have a Fedora 1 Linux system with 
NVidia card. Every time XFree86 libraries are updated this message comes 
back (just got it again). This seems to be caused by some mismatch 
between XFree86 and NVidia driver (from NVidia.com). There is more info 
on that on Fedora or RedHat mailing lists. An "easy" fix is to force 
reinstall of the NVidia driver using command:
$ nvidia-installer -f
This needs to be done as root and with X windows shut down. If this does 
not work for in your case, you need to check Fedora or RedHat mailing 
list, or whatever OS you are using, for alternative approaches.
