Check the file .fonts.conf in your home directory. This is the stanza
to turn off RGB antialiasing:

 <match target="font" >
  <edit mode="assign" name="rgba" >

You also have to check if this setting has actually been taken over into
the X server resource database (restarting X or a new log in with
[xkg]dm is necessary after you change .fonts.conf):

$ xrdb -query | grep Xft
Xft.antialias:  1
Xft.hinting:    1
Xft.hintstyle:  hintfull
Xft.rgba:       none

If you use KDE or if you have the font problem with Qt applications
then you also should check this setting:

$ grep Xft ~/.qt/qtrc

Finally, if all else fails you can try different options for fontconfig
by running (as root)

dpkg-reconfigure fontconfig-config
