64MB RAM.  That looks good.  :-)

Did you set the font in ~/.Xresource?  By default, crxvt uses the 16x15
taipei16 bitmap font (from ETen?) from the xfonts-intl-chinese package. 
Does that (taipei16) work?

For your information, I am currently using:


export LANG=zh_TW.Big5
xcin &
crxvt -ls \
  -fm '-Arphic-AR PL Mingti2L Big5-medium-r-normal--24-0-0-0-c-0-big5-0' \
  -fn '-Arphic-AR PL Mingti2L Big5-medium-r-normal--24-0-0-0-c-0-iso8859-1' \

It works fine here.  Hmm... I wonder what the problem is...

If you happen to have some fonts from Microsoft Windows, say times.ttf and
arial.ttf, try them out and see if they can be displayed properly.

ttf-arphic-xxxxxxx 2.10-9?  You meant "2.10-1", right?  :-)

Please download xfonts-arphic-xxxxxxxx_2.11.  2.10 added way too many
aliases (648 of them), and those extraneous aliases have been removed.  Now,
only 88 aliases.  That should reduce xfs-xtt / Xserver's overhead.  Please
try it out and let me know if it solves the problem.  Use "wget" or "snarf"
to get the following files:

Looks good.  :-)

Please remove /usr/X11R6/lib/X11/fonts/chinese from the list.  This might
solve the problem.

Also, please do a "ls -l /usr/X11R6/lib/X11/fonts/chinese" and let me know
what's in there.  If all it contains is fonts.dir and/or fonts.alias, then
you may safely do a "rm -rf /usr/X11R6/lib/X11/fonts/chinese" too.

/usr/X11R6/lib/X11/fonts/chinese is a left-over from the old
xfonts-cmex24-big5p package, which is now superceded by the new
xfonts-cmex-big5p package.  The old package installed fonts in its own
/usr/X11R6/lib/X11/fonts/chinese directory, but that didn't comply with
Debian's X policy, so in the new xfonts-cmex-big5p package, the Chinese
fonts were moved to /usr/X11R6/lib/X11/fonts/misc instead. 
/usr/X11R6/lib/X11/fonts/chinese was left behind by mistake.
See  http://bugs.debian.org/54994  for more information.

Oh wait, I almost forgot!  One more thing: the "deferglyphs = all" line MUST
/be in etc/X11/xfs/config, and the font cache control lines are recommended

	deferglyphs = all

	# font cache control, specified in KB
	cache-hi-mark = 2048
	cache-low-mark = 1433

As well, in /etc/X11/xdm/Xservers, make sure you add the option
"-deferglyphs 16", for example:

	:0 local /usr/bin/X11/X vt7 -deferglyphs 16

If my hypothesis is correct, your Xserver/xfs-xtt did not hang/crash, but
rather, it was trying to load and render the ENTIRE Chinese TTF font with
14000+ glyphs (characters) into the memory.  That would take _quite_ a
while, and might even crash it.  That's where the "deferglyphs" option come
in: to tell both xfs-xtt and the Xserver to load only the fonts it needs. 
That's why you need that option in both /etc/X11/xfs/config and

So, to summerize, please do the following three things:

  1. Install the new (and lighter) xfonts-arphic-*_2.11*.deb
  2. Removing the old/unused fontpath in /etc/X11/xfs/config
  3. Add the deferglyphs option in both /etc/X11/xfs/config and

Let us know if it solves the problem or not.

Hope this helps.
