Ubuntu Lucid (10.04)
---
ENVIRONMENT DETAILS CLIENT:
Ubuntu Lucid x86_64, nxclient 3.4.0-7, gnome session selected in
nxclient, LANG=en_US.utf8, hostname indus, client is behind firewall.
---
ENVIRONMENT DETAILS SERVER:
Ubuntu Lucid x86, freenx-server 0.7.3.git100327.e224628-0~ppa7~lucid,
LANG=es_ES.utf8, hostname adara, using ENABLE_SU_AUTHENTICATION

**Comment: I interpret the information above (erroneously?) as meaning
that nxagent exited with error since it could not find the font
'fixed'.

I ran 'dpkg-reconfigure fontconfig' and it didn't seem to do anything
interesting like give me a choice to install a bitmapped font. It spit
out a bunch of info about rebuilding font caches but didn't give me an
opportunity to make any choices.

I got the notion (wrong?) that I should set the Xorg FontPath through
AGENT_EXTRA_OPTIONS_X here:

I'd appreciate any help you could give me.

Cheers,
Carlos
