Before ?? Are you sure it works now. Do you have another non root user you 
can try ??

If root works over nx, it's probably the user account isn't it?? rather 
than FreeNX . . .

It's not always /etc/X11/xdm/Xsession, so as long as you aren't trying a 
default X . . .

OK, but you are using 3.3 which will do fine . . .

This stuff is from /usr/share/X11/xkb/compat/xfree86

Looks like your XKB keyboard extensions are not doing so well !!

xkbcomp compiles the keyboard extensions . . .

. . . or maybe not in your case !!

Not fatal to X as it says, but the keyboard doesn't work !!

Well this is ( or would be ) a compiled map for display :1007, used rather 
than the default . . .

Does /var/lib/xkb/compiled/ exist ?? Is it mounted ro ?? Is something else 
using it ( shouldn't be two display :1007s )??

root should be able to write anywhere !!


Note X uses the trick of deleteing the file after reading it, so don't 
expect to find compiled files everywhere


However, X should fall back to a default map, so check what you have set 
as the default in /etc/X11/xorg.conf cos if that doesn't work with a 
pc105/US ( or whatever you have ) you will get the same result ( root 
could be using a different xorg.xonf )

In my view, this is not a FreeNX issue.


If I were you, I'd check if your default keyboard is different from your 
actual keyboard, patch up to date, and then if that doesn't fix it, hit 
your distro's knowledge base.

There might be a bug in your xkbdcomp, ( would be my guess ) but I'm not 
really into deep magic !!!

Let us know how you get on tho' !!
