GLX Error

[nukem]

When ever I try to run my program on my laptop(IBM Thinkpad 1.5ghz Centrino ATI radeon 7500 32meg DRI drivers) running gentoo(latest of everything 2.6.5 vanilla kernel) I get this run-time error.

Couldnt setup window: Couldn't find matching GLX visual

The code compiles just fine and works just fine on my desktop. Other apps that use OpenGL such as Quake III Enemy-Territory run just fine.

Does anyone have a clue?

Thanks

What sort of visual are you requesting? Do you see a visual that matches what you are requesting in the output of glxinfo?

[nukem]

The visual I am using is just a window, basicly the same as glxgears. The more advanced OpenGL calls I make sure the system has(multi texturing) here is my glxinfo

What do you use in order to make your visual ? glxCreateVisual() ? or glxGetVisualFromFBConfig.
Unfortunately, glx 1.3 doesn't run on ATI.

Are you sure you set the colors, buffers... (all the glx attributes) to match what your system support ?

I still don't know well for ATI, but it may be because you don't use the ATI drivers that your program isn't set correctly.

I have SDL handle all that stuff, my code makes no calls to glx directly. I cannt use the ATI drivers my card is not supported by the offical ones so I must use the DRI ones.

You use SDL, not glx. If that's what you do, then here is a probably solution for your problem:

It seems latest Mesa is in version 6. And you seems to have only Mesa 4.0. You may look for update your SDL too. After that there will have no problem I think.

Finally, do you recompile your program on your laptop, or do you simply run the binary ?

[nukem]

I am running DRI from the kernel(2.6.6 kernel) and dont even have mesa installed. Mesa is a software rendering and DRI is a hardware render that uses Mesa for the OpenGL stuff. I run gentoo bleeding edge so everything is fully up to date. Also I do recompile on my laptop.

First, you use Mesa. That's your glxinfo that tells me that:

OpenGL renderer string: Mesa DRI Radeon 20020611 AGP 4x x86/SSE TCL

I don't remember how Mesa fill the opengl renderer string, but this looks it is. So I think you are using Mesa.

And you use version 4:

OpenGL version string: 1.2 Mesa 4.0.4

Now Mesa is in version 6.

If you don't have Mesa installed, tell me what is your opengl implementation on your machine. Is it the free ATI drivers ? Is it the proprietary one ?

Second, DRI isn't hardware like you told it is. DRI means Direct Rendering Infrastructure if I remember well, and is only a mean for gl applications to directly access the renderer, without having to go threw several X layers. Mesa provides a mean to take proffit of DRI.
Saying DRI let you access the hardware doesn't mean DRI is a 'hardware render'. DRI allows you fastest results than without, but DRI cannot tell you can have T&L for example.

What I can say now is that you may upgrade to Mesa 6 and check for latest SDL versions too as your system is up to date.

Finally, your latest kernel version may also be a reason why you have this sort of problem.

I cannot tell much more, I may misunderstand some of what you mean.

[nukem]

Maybe im getting things wrong but I know I have the free ATI rendering drivers.

I figured it out after switching to x.org and looking through my xorg.conf file. I needed to change the default depth to 24.
