Вынул NVIDIA-видюшку из системника, заместо неё теперь работает интеграшка AMD 785G. Драйвер xf86-video-ati-7.5.0 (xorg-drivers-7.7), xorg-server-1.17.4.
Xorg.conf взял из ранее сохранённого для этой интеграшки:

X'ы стартуют, Xfce прогружается и работает. Но пробую запустить glxgears:
> glxgears
Xlib: extension "GLX" missing on display "unix:0.0".
Error: couldn't get an RGB, Double-buffered visual
Как исправить? Раньше (на другой версии Xorg с этой видюшкой) всё работало. Перекомпилировать нужно что-то?
