Whoops. I didn't need the server GLX info... Here you go. Code: GLX Information Direct Rendering: Yes GLX Extensions: GLX_EXT_visual_info GLX_EXT_visual_rating GLX_SGIX_fbconfig GLX_SGIX_pbuffer GLX_SGI_video_sync GLX_SGI_swap_control GLX_EXT_swap_control GLX_EXT_texture_from_pixmap GLX_ARB_create_context GLX_ARB_create_context_profile GLX_EXT_create_context_es2_profile GLX_ARB_create_context_robustness GLX_ARB_multisample GLX_NV_float_buffer GLX_ARB_fbconfig_float GLX_EXT_framebuffer_sRGB GLX_ARB_get_proc_address And this is the ouput of 'glxinfo | grep direct'. Code: direct rendering: Yes GL_EXT_Cg_shader, GL_EXT_depth_bounds_test, GL_EXT_direct_state_access, > Maybe you installed the drivers without rebooting?
