Do you mean "Can't open display"? This is because your DISPLAY variable 
isn't set. To test this, do

# echo $DISPLAY

Assuming your shell is bash (echo $SHELL), you can set DISPLAY by doing

# export DISPLAY=

To ensure this is done automatically, check that this is a line in the or startxwin.bat script you use to start XFree. The default 
example scripts do contain this command.
