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.
