Non-root users cannot run Xwindow

[Aaron White]

Thanks to all, our xclock problem seems to be fixed; Xwindows are now
displaying on my XP machine.

Can anyone shed some light on the meaning of this error message:

~/jre/1.4.2/lib/i386/libawt.so: /usr/X11R6/lib/libXp.so.6: undefined
symbol: _Xsetlocale

It's happening when trying to start a java gui app; we had been led to
believe that this error was something to do with displaying xwindows,
however that no longer seems to be the problem.

Yes, and yes.  either a full-blown Xserver, or at least vncviewer, with
some
chicanery at the server-side...

If you're using SSH, do not change the DISPLAY variable.  SSH is
supposed to
take care of that itself...
