If FIT2D fails to start-up properly, this can be due to one of a number of reasons, which are outside the control of FIT2D.
If the following message appears, or one similar, it means that the present available system virtual memory size is too small.
Not enough memory
This problem may appear and go away simply owing to other users starting and finishing processes. If this is a persistent problem see your system administrator.
If the welcome text appears, but afterwards a message similar to the following appears, it is necessary to authorise another workstation (client) to communicate with your workstation (you have a remote login).
Xlib: connection to ``da1:0.0'' refused by server
Xlib: Client is not authorized to connect to Server
Failed to open X-11 display
ERROR: X-11 workstation not opened successfully (LG_OPEN_WK)
STATUS: The error was identified in module:
LG: ``Light Graphics''
STATUS: Position where error condition was identified
Subroutine LG_X11_OPEN V0.3
STATUS: The error condition has been classified as:
Failed to open X-11 window (use ``xhost+'' on X-server ?)
WARNING: The graphics window could not be opened, therefore the graphics
has been turned-off. You will need to change something to be
able to output the graphics e.g. xhost+ on an X-server. Or
maybe the ``DISPLAY'' environment variable is not set correctly.
You can type:
printenv DISPLAY
at the command line (C-shell and T-shell) to check.
Following this you need to re-start FIT2D.
To add the remote workstation to the list of allowed communicating workstations use xhost e.g. if the remote workstation is called da2, it is necessary to type the following command on your workstation:
xhost +da2
