Hi David,

Xvfb solution worked perfectly. Thanks. I have a question, though.
According to the users, this same scilab thing was working fine before. 
Then I performed a complete OS upgrade from SuSE Pro 9.0 to 9.3 in 
October, 2005. I modified /etc/inittab to set the default init level to 
3. Would any of these affect how scilab works in batch mode. It did not 
require a DISPLAY environment before, but started complaining about it 
recently. I am trying to find out the exact time when it stopped 
working, but because this particular application is not used frequently, 
I may not get to know the exact time of failure.
