Chapter 13. Configuring GLX in Xinerama

The NVIDIA Linux Driver supports GLX when Xinerama is enabled on similar GPUs. The Xinerama extension takes multiple physical X screens (possibly spanning multiple GPUs), and binds them into one logical X screen. This allows windows to be dragged between GPUs and to span across multiple GPUs. The NVIDIA driver supports hardware accelerated OpenGL rendering across all NVIDIA GPUs when Xinerama is enabled.

To configure Xinerama

  1. Configure multiple X screens (refer to the xorg.conf man page for details).

  2. Enable Xinerama by adding the line

        Option "Xinerama" "True"

    to the "ServerFlags" section of your X config file.
