Cause
Following PATH is configured with default OS installation.
/usr/X11R6/lib/X11/fonts/misc:unscaled,/usr/X11R6/lib/X11/fonts/75dpi:unscaled,/usr/X11R6/lib/X11/fonts/100dpi:unscaled,/usr/X11R6/lib/X11/fonts/Type1,/usr/X11R6/lib/X11/fonts/URW,/usr/X11R6/lib/X11/fonts/truetype,/usr/X11R6/lib/X11/fonts/uni:unscaled,/opt/kde3/share/fonts
Deleting fonts and/or having inadequate Font Path causes NVGUI/NVCONFIGURATOR not to launch. -
Resolution
Add above Font Path (and/or install additional fonts if required) by "xset +fp [path]" command. Then run "xset fp rehash" to reload the font paths and make sure the change is reflected by "xset -q" command.
