I have been successfully running XGRASS 4.1 on a SUN Sparc 2 with all interaction
through a PC running a Hummingbird X server. No problems.
Make sure you set your display variable appropriately. Mine is:
setenv DISPLAY dotson:0.0
Also, make sure you allow access to your X server from the remote machine.
On SUNs and Decstations the following command will do this:
xhost +
This will allow anyone to create a window on your display.
Good Luck.
