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
fonts.
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
[snip]
Font Path:
/usr/local/share/lyx/xfonts,/usr/lib/X11/fonts/decwin/100dpi/,/usr/lib/X11/fo
nts/100dpi/,/usr/lib/X11/fonts/misc/,/usr/lib/X11/fonts/75dpi/,/usr/lib/X11/fo
nts/Type1Adobe/,/usr/lib/X11/fonts/Speedo/,/usr/lib/X11/fonts/Type1/,/usr/lib/
X11/fonts/user/100dpi/,/usr/lib/X11/fonts/user/misc/,/usr/dt/config/xfonts/C/,
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
#
lyxmathfontsdir=/usr/local/share/lyx/xfonts
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
fi
fi
That should do the trick for you too
