Re: how can i improve open gl performance on a tibook 400?

[Shawn Powers <spowers@inland.k12.mi.us>]

ahh -- there are more detailed messages about what I had to do to get 
opengl working on my ibook (with a rage128) but basically, I had to set 
my colors to 16bit rather than 24 bit...  that was the deciding factor. 
 If you have a rage128 you DON'T need dri-trunk or anything like that, 
and honestly, that whole bit confused me as well.

you can just run dpkg-reconfigure xfree86  (that's not the actual 
package name, i don't remember off-hand, and I'm stuck on a windows 
machine right now)  It'll ask you a bunch of stuff, you want 16bit 
color, and you DO want it to add the DRI part.  after that, restart 
xwindows and run glxinfo, it should say direct hardware rendering = yes. 
 Also, you can run glxgears, and those puppies should be spinning like 
mad (300 fps or so)

Good luck, if you can't figure it out -- I'll be happy to help more.  It 
took me a long time to get it, hopefully my struggles will help you. :) 
 (The big key was the 16 bit color)
