-c filename
Use configuration file for Screen; on your target, the configuration file is located under: /usr/lib/graphics/target/graphics.conf where target is the platform of your target.
-u username
Switch to username after initialization. This option makes screen switch from running as root to running as username. Running as a general user provides a more secure runtime environment. If there are any unpredictable applications on the system, they won't be able to leverage screen to run undesirable code as a privileged user.
