userland programs such as xpdf ,communicator,  mozilla..etc can prevent
server failure with:
'caught signal 11..' by not loading the speedo and Type1 font dir at
server startup. This works well for me.
-use xf86config to configure /etc/X11/XF786Config file. The code has
changed for generating this
file . There also is a vast difference in 4.3.0 over 4.2.1 on fonts and
how they are called. My modified XF86Config file sections..
# This loads the Type1 and FreeType font modules
#    Load        "type1"
#    Load        "speedo"
    Load        "freetype"
    Load        "xtt"

   FontPath   "/usr/X11R6/lib/X11/fonts/local/"
    FontPath   "/usr/X11R6/lib/X11/fonts/misc/"
    FontPath   "/usr/X11R6/lib/X11/fonts/75dpi/:unscaled"
    FontPath   "/usr/X11R6/lib/X11/fonts/100dpi/:unscaled"
#    FontPath   "/usr/X11R6/lib/X11/fonts/Speedo/"
#    FontPath   "/usr/X11R6/lib/X11/fonts/Type1/"
    FontPath   "/usr/X11R6/lib/X11/fonts/TrueType/"
    FontPath   "/usr/X11R6/lib/X11/fonts/freefont/"
    FontPath   "/usr/X11R6/lib/X11/fonts/75dpi/"
    FontPath   "/usr/X11R6/lib/X11/fonts/100dpi/"
I have been banging on a PWS600 and spare 164LX box, They both now
'work'
XFree86 server does not fail. emacs21 works well .

I will offer pathed xsrc-4.3.0.tar.gz
at my site shortly. The server generates tail end /var/log/XFree86.0.log
wsmouse messages as does
4.2.1, and the return to 'text' mode on the 164LX is black on black
(ctrl-alt-bkspace)[supported Nvidia cards]. use the flashing cursor
option or be prepared to work only in X.
