[IDV #ICF-197843]: IDV - Xlib: extension "XFree86-DRI" missing on display ":0.0"

Hi HP-

> Hardware Information: Java: home: C:\\Programme\\IDV_2.2b3\\jre version:

> Inquiry: Hi

> Xlib: extension "XFree86-DRI" missing on display ":0.0".

You can comment out the load "dri" in your XFree86Config or xorg.conf
file (dependingon the x server you are using).  Without dri, you
may see slower rendering on large displays and intensive displays 
(e.g. volume rendering).  

Some more information was posted on the VisAD list a while back which
you can access at:

and you might try the solutions listed in that thread.
