Cant run the game

[halfempty]

When I try to run I get the following error:

------- video initialization -------
SDL version: 1.2.11
I: desktop depth: 16bpp
I: setting mode 6: 1024x768 (fullscreen: no)
libGL warning: 3D driver claims to not support visual 0x57
SDL SetVideoMode failed: Couldn't find matching GLX visual - try to change the r_bitdepth, r_colordepth and r_stencilsize value
Failed to set video mode 1024x768 windowed.
SDL SetVideoMode failed: Couldn't find matching GLX visual - try to change the r_bitdepth, r_colordepth and r_stencilsize value
Error: Video subsystem failed to initialize

I have a somewhat older computer but have no idea what this means.  Any help would be appreciated.

set your desktop depth to 32 bit (24 bit)

I fight with the same problem on a 5-6 years old Dell Inspiron 4100 under Ubuntu 7.10. Basically you need to have 3D rendering working! See

In my case the 3D rendering works only with "I: desktop depth: 16bpp" (the video card has only 16MB) so I'm not sure if I'll be able to play the ufo anyway...
