Dear all,

(Kees read on. There's sone new info for you at the bottom...)

one of the things that LyX 1.2 can do for you is display most of the 
mathematical symbols you'll ever use in a WYSIWYG way. However, you'll need 
to first perform a little magic with your font path.

To display \epsilon and any of the AMS symbols like \sqcup and 
\blacktriangledown you'll need to tell the font server where to find these 

Look in /usr/local/share/lyx, or wherever you have installed the lyx support 
stuff. You'll find a directory xfonts containing symbolic links to a number 
of fonts used by LyX (if you have them installed). If you have them, then you 
should check whether this directory is in your font path. Type
        xset -q
at the console. Here I get

Font Path:

Note the all important /usr/local/share/lyx/xfonts.

To add the equivalent to your font path, if it isn't already there, type
        xset +fp PATH_TO_YOUR_LYX_FONTS_DIR

Unfortunately, I understand that this magic will not work if you are running 
LyX remotely. Sorry!

Well, you only need to do this once per xsession. Here, I have added the 
following to my .xsession file:

# Some fonts for LyX

if [ -d $lyxmathfontsdir ]; then
    xset q | grep $lyxmathfontsdir
    if [ $?  -ne 0 ]; then
        # directory is not already in the font path
        # so add it:
        xset +fp $lyxmathfontsdir; xset fp rehash

That should do the trick for you too
