Runtime Configuration
Xorg provides several mechanisms that provide configuration and run-time parameters:
- Command line options
- Environment variables
-
xorg.conf
andxorg.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 configuringxorg.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.
