Hi there,

good news: the DRI acceleration is working now (at least here,
tested on different machines). Congrats to Roberto Flor.

The fix is in CVS, if you want to test:

 cvs up -dP src.contrib/GMSL/NVIZ2.2
 gmake5 -i src.contrib/GMSL/NVIZ2.2

Roberto has upgraded the togl.c to 1.5 (which was already living in
GMSL/NVIZ2.2/TOGL for amusement). The real fix was that the wrong
tkInt was included (fixed now). Even the original TOGL packages
contain this bug...

So - don't forget to activate DRI in /etc/X11/XF98config[-4].
The "gears" program or "glxinfo" will tell you about DRI running.

NVIZ is really FAST now.

Thanks to Roberto Flor from ITC-irst,
