You may need to define a special environment variable, SAS_ALT_DISPLAY,
because some server features require a valid X Windows System graphics display.
This environment variable will be used to locate a graphics display when the
value of the environment variable commonly used by the X Window System, DISPLAY,
has not been set. The value of SAS_ALT_DISPLAY must refer to a display that
will always be available during the operation of a SAS server. For example,
if the server machine on which SAS servers are running also runs an X server,
then set the value of SAS_ALT_DISPLAY to the name of the server machine. To
set the SAS_ALT_DISPLAY environment variable, edit the file !SASROOT/bin/sasenv and substitute your display name for value:0.0 in the line,
SAS_ALT_DISPLAY=value:0.0
If an X server is not available on the server machine, an alternative
is to use the X virtual frame buffer (Xvfb) as supplied by the operating system
vendor. Refer to your vendor-supplied documentation for information on the
use of Xvfb.
