[SOLVED] Два GPU: Nvidia и ATI

Итак, у меня две видеокарты в компьютере: ATI Radeon HD6950 и NVidia GeForce 7900GS. В мониторе есть провода DVI и VGA, поэтому существует возможность подключить оба, переключаясь кнопкой на мониторе.

Когда я описываю в xorg.conf только одно устройство в ServerLayout - все работает отлично, но когда два - в логах не появляется никаких ошибок, но и работающих Иксов я не вижу ни на одной из видеокарт.

Не получится одновременно

Не получится одновременно использовать два проприетарных драйвера.

Библиотеки проприетарного драйвера NVIDIA устанавливаются в /usr/lib/opengl/nvidia/, примерно так:

/usr/lib/opengl/nvidia/lib/
/usr/lib/opengl/nvidia/lib/libGLESv2.so.334.21
/usr/lib/opengl/nvidia/lib/libGL.so.334.21
/usr/lib/opengl/nvidia/lib/libGL.so.1
/usr/lib/opengl/nvidia/lib/libEGL.so.334.21
/usr/lib/opengl/nvidia/lib/libGLESv1_CM.so
/usr/lib/opengl/nvidia/lib/libGLESv1_CM.so.334.21
/usr/lib/opengl/nvidia/lib/libGLESv1_CM.so.1
/usr/lib/opengl/nvidia/lib/libEGL.so
/usr/lib/opengl/nvidia/lib/libEGL.so.1
/usr/lib/opengl/nvidia/lib/libGLESv2.so.2
/usr/lib/opengl/nvidia/lib/libGLESv2.so
/usr/lib/opengl/nvidia/lib/libGL.so

а библиотеки mesa (открытых драйверов) устанавливаются в /usr/lib/opengl/xorg-x11/, примерно так:

/usr/lib/opengl/xorg-x11/lib/
/usr/lib/opengl/xorg-x11/lib/libEGL.so
/usr/lib/opengl/xorg-x11/lib/libEGL.so.1
/usr/lib/opengl/xorg-x11/lib/libEGL.so.1.0.0
/usr/lib/opengl/xorg-x11/lib/libGL.so
/usr/lib/opengl/xorg-x11/lib/libGL.so.1
/usr/lib/opengl/xorg-x11/lib/libGL.so.1.2.0
/usr/lib/opengl/xorg-x11/lib/libGLESv2.so
/usr/lib/opengl/xorg-x11/lib/libGLESv2.so.2
/usr/lib/opengl/xorg-x11/lib/libGLESv2.so.2.0.0

Посредством вызова 'eselect opengl set' устанавливается ссылки на выбранную реализацию opengl, в случае nvidia имеем примерно следующее:

/usr/lib/libGLESv1_CM.so -> opengl/nvidia/lib/libGLESv1_CM.so.334.21
/usr/lib/libGLESv1_CM.so.1 -> opengl/nvidia/lib/libGLESv1_CM.so.334.21
/usr/lib/libGLESv2.so -> opengl/nvidia/lib/libGLESv2.so.334.21
/usr/lib/libGLESv2.so.2 -> opengl/nvidia/lib/libGLESv2.so.334.21
/usr/lib/libGL.so -> opengl/nvidia/lib/libGL.so.334.21
/usr/lib/libGL.so.1 -> opengl/nvidia/lib/libGL.so.334.21

С проприетарным драйвером AMD ситуация примерно такая же.

Из-за того, что в проприетарных драйверах используются свои реализации библиотек libGL и прочих одновременно их использовать на одном xorg-server`е не получится.

Но вы можете "завести" обе карты на открытых видео драйверах Nouveau и Radeon на одном xorg-server`е либо на двух разных xorg-server`ах, с двумя разными файлами xorg.conf, указывая в них путь до директории с модулями:

Section "Files"
   ModulePath /usr/lib/opengl/nvidia,/usr/lib/xorg/modules
EndSection

Спасибо, усек. Буду думать,

Спасибо, усек. Буду думать, что мне больше подходит.
