Command to verify hardware acceleration (only works inside xorg session):
Positive example:
$ glxinfo | grep render
direct rendering: Yes
GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer,
GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer,
Extended renderer info (GLX_MESA_query_renderer):
OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 530 (Skylake GT2)
GL_ARB_conditional_render_inverted, GL_ARB_conservative_depth,
GL_NV_conditional_render, GL_NV_depth_clamp, GL_NV_packed_depth_stencil,
GL_ARB_conditional_render_inverted, GL_ARB_conservative_depth,
GL_MESA_window_pos, GL_NV_blend_square, GL_NV_conditional_render,
GL_OES_element_index_uint, GL_OES_fbo_render_mipmap,
Negative example (llvmpipe (LLVM 6.0, 256 bits) means it’s using software rendering):
$ glxinfo | grep render
direct rendering: Yes
GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer,
GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer,
Extended renderer info (GLX_MESA_query_renderer):
OpenGL renderer string: llvmpipe (LLVM 6.0, 256 bits)
GL_ARB_conditional_render_inverted, GL_ARB_conservative_depth,
GL_NV_conditional_render, GL_NV_depth_clamp, GL_NV_packed_depth_stencil,
GL_ARB_conditional_render_inverted, GL_ARB_conservative_depth,
GL_NV_blend_square, GL_NV_conditional_render, GL_NV_depth_clamp,
GL_OES_element_index_uint, GL_OES_fbo_render_mipmap,
