Thanks for the reply Uli. Pasted output below

Also, I was scratching my head some more after sending the previous email.
Would I run the two lines below to add these links manually? Or should I do
something more/else?

ln -s /usr/lib64/libNX_X11.so.6     /usr/lib64/nx/X11/libX11.so.6
ln -s /usr/lib64/libNX_X11.so.6.3.0 /usr/lib64/nx/X11/libX11.so.6.3.0


Best, A.
