Start Screen services
screen -c filename [-u username]
QNX Neutrino
Specify filename as the absolute pathname to the configuration file that Screen will use. For example:
$ screen -c /usr/lib/graphics/platform/graphics.conf
where platform is the name of your target's platform (e.g., imx6x).
You must specify this -c option. Otherwise, screen won't run.
On your target, all libraries that you specify in the khronos section of your configuration file should reside in the same directory as the configuration file itself.
Run the screen binary from command line to start Screen services. To run screen on your target:
screen -c /usr/lib/graphics/iMX6/graphics.conf
screen -u joe
