we had similar problem creating our panels... I hope tomorrow to give you more 
info when my collegue Massimo Cuomo back to office.

NO!... don't change it... you should investigate inside the mksurfPanel module 
taht you can find in the script directory

i found it in the <grass install path>/etc/nviz2.2/scripts/panel_surf.tcl

investigate inside this tcl code, but...

I thing it's bettere to investigate on driver setting in /etc/X11R6
