I am having problems rendering textures on almost all my 3-D applications.
I suspect that my fglrx acceleration or my OpenGL or freeGLUT might be to blame.

Here are the problems:
1. Extreme Tux Racer - some textures and 2-d images are incorrectly rendered, I get an area of black, with a distorted picture that gradually becomes random colored dots, as you look across the picture away from the black.

2. VegaStrike - On some spaceships + bases, I get funky coloring with the randomness of problem 1, and some black areas too

3. SecondLife - I can't even get a window open! It says it could not GLrendertexture or something, and has a segmentation fault.

I believe all these problems are related. I ran glxinfo | grep render, and got:
direct rendering: Yes
OpenGL renderer string: ATI Radeon HD 3870
GL_NV_conditional_render, GL_NV_texgen_reflection,

does anyone have any idea what on earth is wrong here? This is driving me crazy!

first how did you install the ati driver ??
here is a link to the fedora 10 how to
"Howto for fglrx (Ati driver) and Compiz-fusion"
http://forums.fedoraforum.org/showthread.php?t=155503

the open source akmod-fglrx is the preferred
or if needed the "ATI Catalyst" from ATI's web site
the akmod-fglrx.rpm is the best way

I actually used the link you provided for the graphics. I used some of the Fedora 9 directions, because the Fedora 10 ones didn't work for my ATI radeon 3870.

I used the rpmfusion fglrx driver... I'm not sure which one that is... probably the akmod.

to see WHAT you installed can you post the output of
this will list what is installed for that driver
? is that ati card a ATI Radeon HD 3xxx series ???
or just the very old ATI Radeon 3xxx series ??
if it is the OLD card then there may BE NO WORKING driver for the new xorg,X11that is in fedora 9 , 10 , and 11-alpha .
fedora 8 may be the last working version seeing as ati did not update there drivers

seeing as you have a working GUI ( Gnome? or KDE?) then this won't help

using the 2d vesa driver
have a look through these posts from a search for "ATI radeon 3870"

but this might shed some light on to your problem

PS ATI is still( but slowly getting better) a MS "mostly" shop , they were a MS only shop not to long ago .

I have the akmod-fglrx. Thanks for reminding me, the card is a Radeon HD 3870.
What's this about using xvesa?
is that a good idea?
if so, how do I do it?

strangely, there are some 3-d games which do the textures correctly... it's always the same images that do it.

I don't know what this means, but I'm starting to suspect the freeGLUT...

the last link then will apply to your HD card

check the last post ( page 4) of that thread

Ok, this is probably just a dumb question. I think there may have been a post between this message and yours.

Do I need to downgrade the libdrm, or do I need to run the commands
sorry for any inconvenience...

i am using a nvidia card so..
but it seems that the "rpmfusion-nonfree-update-testing" testing repo , should be in the standard by now
rpmfusion-nonfree-update.repo
-- that post is a month old --
should work after you run
