"couldn't Find Matching Glx Visual"

[Capn_Fish]

I wrote a small OpenGL/SDL app that I compiled on my Z. It build without complaint, but when I tried to run it, it said

Code: [Select]

Couldn't find matching GLX visual
Am I missing a package? Or is a package already installed just not configured with OpenGL?

Thanks.

I had the same problem with the Ubuntu UME launcher. I replaced the xserver-kdrive by xserver-xorg and used the glx module.
At least that works. I don't know of any other options

I kind of figured that that was the case. Oh, well...

How much slower do things run with xorg?

I just installed Xorg (apt-get install xorg-core, I believe), but it doesn't work correctly:

-The mouse is weird (you tap 50% off center of the screen, and it registers as being tapped on the very edge)
-I can't get it to start with "startx," even after linking it to /usr/bin/X, Xfbdev still loads
-When I try to run "/usr/bin/Xorg & sh ~/.xinitrc," it crashes saying "FBIOPUT_VSCREENINFO succeeded but modified mode" and "mode initialization failed"

Could somebody post a how-to?

Thanks.

EDIT: It also says "Xlib: extension "RANDR" missing on display ":0.0"

I had the above problem.  

Changed ~/.xserverrc

to exec "Xorg"  instead of "Xfbdev" and Xorg works instead.  Much nicer,and much much heavier.  Fonts are nicer, opengl/mesa works, but really slow.

glxgears gives about 15 fps max, and more like 4 fps average at a guess. Everything is prettier though.  This works a lot smoother than debian's prebuilt binary in pdaxrom and probably angstrom too.  How did they do it?

Could somebody post a how-to?

I second this. A how-to would be nice. A rebuilt xserver/drivers would be very nice.

The 2 links above have some info on rebuilding, but I can't afford to tie my machine up that long.
