I got a GeForce 6600 LE running on ubuntu6.06 with Nvidia linux Drivers loaded.
was wondering if it's the card, driver or OS set up causing the problem.
just an anoyance at the moment but I will have to try fix it eventualy

Hmm... What exactly is the problem?

Greetings,

[Recon]

basicly a black screen when i run

 ./walktest stenciltest

and in about ever other CS app i run it says

 could not load plugin 'crystalspace.graphics3d.shader.glcg'

But other than that everything seem to be working.

[Commander]

I just tried this out, and I have an almost black screen. There is a room, but it's really dark in there. -relight doesn't help.

Output is:

Code:

$ ./walktest data/stenciltest/
WARNING: could not load plugin 'crystalspace.window.x.extf86vm'

Cleaning up...
Segmentation fault

The segmentation fault happens when exiting any CS application. It appears somewhere in OpenGL/TLS. Propably the video driver.

Debian Linux testing
Kernel 2.6.15.4
GeForce 2 Ti
nVidia driver 7174

I just updated to revision 25269 and the error output disappeared, but the room is still dark.

Most other apps and maps also show the ...shader.glcg error, propably because I don't have libcg installed when building CS.

[Recon]

Well I installed the CG shader lib then linked and compiled CS. the sharder not loading message is gone.
The ./walktest stenciltest still gives me a black screen. not sure what it's meant to look like.

got the CG lib at
http://developer.nvidia.com/object/cg_toolkit.html
