It seems that 310M does not support BGR/888. I haven`t used NVidia since 2007,
so I can`t even guess the format it might need.
Four main things in question are its RGBA bitmasks. Knowing these I would be
able to forge a suitable DDPIXELFORMAT structure.
Can you please add my printf() to this code and compile/run it on your machine,
and then show the screenshot and post its output?

https://www.opengl.org/wiki/Programming_OpenGL_in_Linux:_GLX_and_Xlib

printf("\nscreen = %d, depth = %d, class = %d\nR = %08X, G = %08X, B =
%08X\nmap = %d, bits = %d\n\n", vi->screen, vi->depth, vi->class, vi->red_mask,
vi->green_mask, vi->blue_mask, vi->colormap_size, vi->bits_per_rgb);

The code and its build line are given at the bottom of the wiki page. The
printf() I need is just above.
It has to be inserted right before glEnable(GL_DEPTH_TEST). I haven`t tested
this line, but I hope it will work as expected.
