Re: Possible XFree86-DRI solution

Hi Andrew,

I could not get this fix to work for me. The only place I have a tls/ directory is /lib/tls.

I have my /usr/lib/ -> ../../usr/X11R6/lib/

I have read that NVidia does not use DRI at all. See:

Did you need to comment out the line:

Load "dri" in your /etc/XF86Config file?

What version of the NVidia drivers do you have?

I guess the biggest question I have is, if I am able to see 3d images, how important is DRI? And, if it is important, should I see an improvement in performance, specifically for the DirectManipulationRendererJ3D, over the DirectManipulationRendererJ2D?

Hi Kevin,

  Thanks a lot for posting that.  We have just started trying to fix
the same problem.  The fix worked for us.

  For others benefit, the problem is with XFree86 4.3 and the current
NVidia driver.  4.3 comes with fedora and is in rawhide.
You get a message like:
  Xlib:  extension "XFree86-DRI" missing on display ":0.0"

  The quick solution is to remove /usr/X11R6/lib/tls
  You may need to then run ldconfig, we didn't.

  glxinfo is a nice utility to let you see if DRI is enabled, of course
you could just run your visad app also.
