Problem with fonts in Emacs
xset +fp /usr/X11R6/lib/X11/fonts/100dpi xset +fp /usr/X11R6/lib/X11/fonts/75dpi xset fp rehash
Permanent solution: add the following lines to /etc/X11/xorg.conf as root (under the "Files" section):
FontPath "/usr/X11R6/lib/X11/fonts/100dpi" FontPath "/usr/X11R6/lib/X11/fonts/75dpi"
