See Debian xorg.conf file problem solved.

Also you may want to see if your xorg.conf file has it located, in the Files section 

Section "Files"
# The location of the RGB database.  Note, this is the name of the
# file minus the extension (like ".txt" or ".db").  There is normally
# no need to change the default.
    RgbPath     "/usr/share/X11/rgb"
