Em um Dell XPS 13 com Ubuntu 14.04 pré-instalado, tenho problemas para executar programas de exemplo OpenGL (www.opengl-tutorial.org). Tudo compila bem, porém a janela na tela fica preta ou mostra alguns artefatos. Mesa parece estar atualizado e deve ser capaz de entender o OpenGL 3.3;
$ glxinfo | grep version
server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.1.3
OpenGL core profile shading language version string: 3.30
OpenGL version string: 3.0 Mesa 10.1.3
OpenGL shading language version string: 1.30
$glxinfo | grep renderer
GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer,
GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer,
OpenGL renderer string: Mesa DRI Intel(R) Broadwell

Alguma ideia do que posso fazer para usar o OpenGL?
Obrigado, Helmar
