Both alternatives have the same effect as setting XLIB_SKIP_ARGB_VISUALS.
Motif, the widget library that NEdit uses, has a problem with the new 
kind of visuals that are introduced in X.Org (ARGB visuals, with a 
transparency bit plane).

By setting XLIB_SKIP_ARGB_VISUALS you are telling the X library to hide 
this kind of visuals from the application, such that it cannot use them.
By disabling ARGB visuals completely in the X-server (via xorg.conf), 
you can obviously solve the problem too.
By telling NEdit to use the default visual instead of letting it choose 
the "best" visual (the one with the largest color depth), you can 
prevent it from selecting an ARGB visual too, since the default one is 
never ARGB.

Note our CVS version now automatically sets XLIB_SKIP_ARGB_VISUALS on 
startup, such that users don't have to bother about that, without 
affecting any other applications.
