[PlayerStage-Gazebo] SGIX rendering

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Hi all,

I've traced the root of my gazebo problems to a new nvidia graphics 
card... so I'm wondering if there's any graphics card gurus out there 
that can give me an idea of what's gone wrong.

I should be able to use the SGIX renderMethod with an nvidia card, 
right? But here's what I get:

$ wxgazebo test.world
starting server
waiting for server
using display [:0]
X Error of failed request:  BadValue (integer parameter out of range for
operation)
   Major opcode of failed request:  145 (GLX)
   Minor opcode of failed request:  27 ()
   Value in failed request:  0x0
   Serial number of failed request:  13
   Current serial number in output stream:  15
server died
stopping server

I've got "direct rendering: Yes" and I should have SGIX pbuffer support 
(see glxinfo output attached below). I can also run other test programs 
like glxgears (1700 fps) and tuxracer no problems.

At the moment wxgazebo crashes with SGIX, and it's not working properly 
with GLXP either. With the GLXP renderMethod I can't display terrain 
models properly... they get chopped off and only a fraction of the total 
terrain file is actually displayed (see my previous post "truncated 
terrain in gazebo").

Installation of the graphics card drivers appeared to go smoothly. I've 
got a GeForce 6200 running under debian kernel 2.6.15-1 (I used the 
nvidia kernel packages from debian to install the drivers).

Can anyone give me an idea where to look / what to do next? I can get 
gazebo to work fine (though very slowly) on this machine with just the 
onboard graphics, so not sure what the problem is. If it's a card/driver 
problem is there any other program I can use to test whether they are 
working ok? Is there a possibility that there's some code in gazebo 
causing the problem?

Any help/suggestions would be greatly appreciated...

Thanks, Solly
