fwcamtest Test Requirements

Start a Window Environment

The system that runs fwcamtest must already be running a window environment, such as CDE or Open Windows. If the system has no window environment, or is only displaying the login window, fwcamtest will neither pass nor fail.

Your window system must be operating in 24-bit depth to run the display test. Instructions for changing this setting are below.

If you are working in CDE, you can change your system to 24-bit depth by editing the file /usr/dt/config/Xservers or /etc/dt/config/Xservers. The file /etc/dt/config/Xservers overrides the file /usr/dt/config/Xservers. Edit the appropriate file to include the following line:

:0   Local local_uid@console root /usr/openwin/bin/Xsun :0 

-nobanner -dev /dev/fbs/ffb0 defdepth 24 defclass TrueColor

If you are working in Open Windows, start Open Windows by typing the following at the shell prompt:

% openwin -dev /dev/fbs/ffb0 defdepth 24

Testing Through a Remote Connection

While running fwcamtest through a remote connection (such as a telnet session), if the DISPLAY variable is not set properly, it will cause numerous warning messages to display. These messages are logged and can fill up the log files. To avoid this, set your DISPLAY variable for the local host, and perform xhost remote_host on the local host before you start SunVTS and run fwcamtest.
