Hi,

I'm using the icculus.org Linux version of the FS2 code and I have had problems getting it to run. I somehow got it running for a while and was able to play a few missons before it broke again. The problems reoccurred after FS2 exited and did not reset the resolution properly.

The symptom is that the window is opened, but it looks like it displays random memory and I get these errors in the log:

General: Bitmap is to small at 0x0.
General: WARNING: Error setting aabitmap texture!

It appears that this OpelGL call returns zero in max_texture_size:

In gropengl.cpp:opengl_max_tex_size_get():
glGetIntegerv( GL_MAX_TEXTURE_SIZE, &max_texture_size );

hence no bitmaps can be loaded. FS2 is not hanging, I can hear the sounds as the pointer moves over buttons on the pilot selection screen and it exits gracefully when I hit Escape. I have tried turning off the computer, thinking it might be solved by rebooting the graphics card (PointOfView GeForce2), but that did not work.

The glxgears program works fine and when I start FS2 after it, the window contains "residual" graphics from it. It's just as if FS2 (or OpenGL) doesn't initialise the card properly.

Here's a shot of the FS2 window with the glxgear data clearly visible: FS2 Problem

I'm grateful for any tips.

This should really be asked on the icculus.org Freespace 2 mailing list, but:

Are you using nVIDIA's drivers? What is the output of glxinfo? Linux distro and version?

max_texture_size is 0 by default so that call probably didn't work and returned an error instead.  With a GeForce 2 you should have a texture size of 2048 so you can just edit src/graphics/gropengl.cpp and change the return from opengl_max_tex_size_get() to 2048 rather than max_texture_size.  I'm betting that there is something else wrong here though.

Thanks for your reply, taylor.

I thought this was a more general forum, covering all versions, my mistake.

Yes, I an using the latest nVidia drivers (5336), Debian unstable, Linux 2.4.24, plus CVS versions of some libs.

I tried returning 2048, but that didn't work either since I got this error instead:

Error: !!DEBUG!! t->texture_handle == 0
General: WARNING: Error setting aabitmap texture!

My guess is that the video card correctly reports zero memory, and the above error is simply that the card couldn't create the texture (glGenTextures() fails). It would have been good if there existed some kind of video card (or OpenGL) utility which could be used to analyse and update settings. I have tried searching for one, but have come up empty handed so far.

I have attached the output of glxinfo at the end of the post. It does not tell me much, though.
