workaround for renderer problem on linux

[nakis]

I had troubles executing nexuiz, so I searched this forum and found many else seems to have the same problems. Now that I have a workaround for some of these, I post it.

Problem arise on linux, it seems only to happen using DRI for Ati Radeon cards. Nexuiz is executed with indirect rendering, so is very slow. If you have this message on log:

GL_RENDERER: Mesa GLX Indirect

try executing nexuiz with this command line:

Code: Select all

LD_PRELOAD="/usr/lib/libGL.so.1" nexuiz

It seems that there're problems loading the shared lybrary /usr/lib/dri/radeon_dri.so. Preloading the GL library may solve them and nexuiz should been executed with direct rendering.

Its been a while and i only used a ati card for a very very short time under linux but i think this

GL_RENDERER: Mesa GLX Indirect

means the ati drivers are not installed and the 3d accelerated opensource driver neither.. (or at least something does not work the way it should)

[nakis]

The opensource driver are installed and working, but Nexuiz doesn't use direct accelleration if the library is not preloaded.

The opensource driver are installed and working, but Nexuiz doesn't use direct accelleration if the library is not preloaded.

That's strange, usually the engine should find libGL.so.1 by itself. Are you shure there isn't another libGL.so.1 other than /usr/lib/libGL.so.1 on your system? (perhaps there's an old one in /usr/X11R6/lib/?)

I don't know, now Nexuiz works correctly with or without GL library preloaded. Something changed in my configuration, but I cannot tell what.
