Using unicode fonts is the easiest way to properly display hindi, arabic, hebrew and other non latin languages. We install the unicode fonts in a local directory and then tell fontconfig to look in that directory. Edit /etc/fonts/local.conf

/usr/ias/share/fonts/fc

Then tell fontconfig to rehash it's tables

[root@host] # fc-cache

Check that your new font is there

[root@host] # fc-list |grep

After modifying gdm.conf we noticed that Xnewt would not start properly on occassion. Xnewt was not ignoring the vt[0-9] command line option sent to X to specify a virtual console on which to run. We removed this from the command line sent to Xnewt and renamed Xnewt to Xnewt.sun

pushd /usr/X11R6/bin
mv Xnewt Xnewt.sun
echo Xnewt
#!/bin/sh

XFIX=`echo $@ |sed -e's/vt[0-9]*//'`
echo `date`: ARGS=$@ XFIX=$XFIX >>/var/log/Xnewt

exec Xnewt.sun $XFIX -fp unix/:7100
EOF
chmod 755 Xnewt
popd
