do glxgears work?
Hmmm... glxgears gives me this:
Error: couldn't get an RGB, Double-buffered visual
I tried to find a way of adjusting this in the graphics card application, but no luck... e
if so, what is your pixel-depth?
Gem wants to create a 24bit buffer, so if you are running your X in 8bit/palette mode it will bail out.
this is what Gem requests: { GLX_RED_SIZE>=4, GLX_GREEN_SIZE>=4, GLX_BLUE_SIZE>=4,
GLX_DEPTH_SIZE>=16,
GLX_STENCIL_SIZE>=8,
GLX_ACCUM_RED_SIZE>=8, GLX_ACCUM_GREEN_SIZE>=8, GLX_ACCUM_BLUE_SIZE>=8,
GLX_DOUBLEBUFFER }
check the output of glxinfo, whether your config supports such a setting.
