Runtime Configuration

Xorg provides several mechanisms that provide configuration and run-time parameters:

  • Command line options
  • Environment variables
  • xorg.conf and xorg.conf.d configuration files
  • Auto-detection
  • Fallback defaults

The SDKprovides utilities for changing the configuration and run-time parameters:

  • xrandr utility—changes runtime parameters
  • nvidia-xconfig helper utility (tool)—assist in configuring xorg.conf
Note:

Customers who support hot plugging of an HDMI display must implement an X11 client that reconfigures the HDMI display upon receipt of an RRScreenChangeNotify X11 event. Typically, a gnome-settings-daemon is used for that purpose.

This solution is required to work around the X11 response to a hot-plugged HDMI display. During that response, X11 registers the HDMI output as connected but does not perform an automatic mode-set.
