X2Go

X2Go is used to remotely access a graphical desktop on our GNU/Linux servers.

Installation

X2Go is available on all desktops in the computer science lab

If you are running OS X 10.8 (Mountain Lion) or later and have not previously installed XQuartz, download and install it from https://xquartz.macosforge.org/ before installing the X2Go client. For versions of Mac OS X earlier than 10.8, you can use the built-in Apple X11 client. More information about X11 can be found here

Download the X2Go client for your operating system

Version 4 of the X2Go client does not work with Mac OS X 10.6 or OS X 10.7. Please use version 3.99 instead

On Mac OS X, mount the dmg file (your browser may do this for you after download) and drag the x2goclient application to your Applications folder.

On Windows, double-click the downloaded setup file and follow the instructions in the wizard to install the software.

Configuration

When you first run the X2Go client, you will be presented with a "New session" dialog. You should fill this in with this information:

You should be sure to leave all other settings at their defaults. Changing other settings may lead to unexpected results and may leave your session unusable.
Once you're done, click OK, and you'll be brought to the main client screen with your new session listed on the right.

Session Types

The session types that we support are:

Connecting

To start the session, click on it and provide your password where prompted

After you click OK, it will connect to the server and start your session. Watch the Status line to see what's happening. Once the status is "running," your session should launch.

When you first connect to a particular server, you may get a dialog box asking you to accept the host key. Click Yes to accept it:

To terminate, either log out of your session or click the terminate button:

Fonts for Windows

When using the X2Go client on Windows, there may be some older programs (e.g. Cadence) where fonts do not show up properly. Symptoms you may see are either blocky, illegible fonts or instances where fonts disappear because they are white on a white background. If you experience any of these, you can install a font package that should eliminate most of these issues. Keep in mind that this is only needed if you are running the X2Go client on Windows. First, if you haven't already, follow the instructions at ThayerFS Connecting to connect to ThayerFS. Navigate to the Courses share (P:), and go to the software\x2go folder. In this folder, double-click the vcxsrv_fonts.exe file to install the fonts. Depending on your security settings, you may need to drag this file to your local computer before double-clicking on it.

Other Settings

If you are using a Mac and need to use the Alt key within remote sessions, you need to change the X11 preferences. Run XQuartz directly from within Applications->Utilities. Then, select the X11->Preferences... menu item, select the Input tab, and check the box next to "Option keys send Alt_L and Alt_R." Close the preferences window and quit X11. Then, restart X2Go and when you log into a remote session, the option key (also labeled alt on most Mac keyboards) will send the Alt key to the remote side.
