X2Go on EECS Instructional Computers
------------------------------------

  X2Go is a Windows program that lets you display graphical applications 
  on your computer from our UNIX computers.  It is faster than X11 (you 
  don't need an Xserver such as Xming, Exceed or Cygwin on your computer) 
  and simplier than NX (there are no matching keys on each computer).

  You can download if from https://wiki.x2go.org .

  These EECS Instructional computers currently accept X2Go connections:

	eda-1.eecs .. eda-8.eecs	(Centos 64-bit Linux servers)
	c125m-6.eecs .. c125m-24.eecs	(Centos workstations in 125 Cory)

  We are adding the server side it to our Linux systems that are commonly 
  used for Matlab, Cadence and Synopsys tools.  If you need it on another 
  server, please ask inst@eecs.berkeley.edu.


CalVisitor Wireless Net Blocks This
-----------------------------------

  Note that the UC Berkeley public wireless network called CalVisitor only
  allows WEB traffic (network ports 80 and 443), so programs such as ssh,
  X11, NX and X2go do not work over CalVisitor.  
  
  See https://airbears.berkeley.edu for information about using the Berkeley 
  AireBears2 authenticated wireless network or VPN instead.


Troubleshooting X2Go
--------------------
  If you are having trouble connecting to our servers,  make sure you
  are not using the "CalVisitor" wireless network: it will block the
  connection.  Also, try switching your X2Go profile from "KDE" to "Gnome".  
  KDE has been slow and unusable in the past.

  The "lowest overhead" technique for your X2go connection is to set the
  X2go profile to use: "Custom Application" ... "Terminal" (those are in
  two popup-menu lists in the "Profile Editor").  This avoids starting a
  big window-manager like KDE or Gnome...yet you can still launch
  graphical apps like virtuoso, matlab, synopsys from the "Graphical
  Terminal" that shows up.  The second best choice, if you prefer to have
  a full remote "desktop display" in X2go...is "XFCE" (simpler/smaller
  option than Gnome or KDE).

  If your Windows account name contains space characters, Chinese
  characters, or non-ASCII characters, X2Go Client will fail to run. You
  must create a new Windows account with an account name that only
  contains alphanumeric characters. Log off from your Windows session,
  and login with the new Windows account before you start X2Go Client.

  If you are having font trouble such as getting boxes rather than letters,
  you probably need to reinstall your copy of x2go and select all of the
  optional fonts.
