Graphics terminals

      If you are using a UNIX-derived system (Linux, MacOS),
      it is quite convenient (and sometimes necessary to avoid
      problems) to do the following:
      
      1. cd $HOME/.ssh 
      2. (Edit the file named 'config' with your favorite editor,
      to add the following stanza (with your number instead of 116 !):

      #-------------
      Host s116
      HostName nord1.bsc.es
      User nct01116
      Protocol 2
      ForwardX11 true
      ForwardX11Trusted true
      #-------------

      Afterwards you can just do:

      ssh s116

      to connect to your account, and to properly forward
      the graphics data.
    

Fix for OpenGL support in the Mac's X11 server

	Some versions of the XQuartz programs in the Mac exhibit
	an obscure bug that prevents the VESTA and XCrysden programs
	to work when executed in the School's computers with a
	remote display on the Mac.

	The fix is to issue this command at the Mac's terminal:

	defaults write org.macosforge.xquartz.X11 enable_iglx -bool true
