   Is there anyone on the list using the RedHat 5.0 distribution of Linux on a
   Thinkpad 755C. I'm having some trouble getting the XF86Config file just
   right. I've pulled a couple of people's Config files from the net but they
   all seem to be from older versions of the Xwinodws server.

   Any help would be appreciated!

Here is my XF86Config. I use it on a 755C running Debian 1.3.1, which
is running XFree86 3.3.

# 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/X11R6/lib/X11/rgb"

# Multiple FontPath entries are allowed (which are concatenated together),
# as well as specifying multiple comma-separated entries in one FontPath
# command (or a combination of both methods)

    FontPath "/usr/X11R6/lib/X11/fonts/misc/"
# FontPath "/usr/X11R6/lib/X11/fonts/Type1/"
# FontPath "/usr/X11R6/lib/X11/fonts/Speedo/"
    FontPath "/usr/X11R6/lib/X11/fonts/75dpi/"
