Using Ubuntu GUI remotely using NoMachine or Xming from Windows 7

Solution 1: NoMachine

Steps:

• Download NoMachine Linux server from here http://www.nomachine.com/select-package.php?os=linux&id=1
  • Follow installation instructions given here http://www.nomachine.com/documents/server/install.php
• Download NoMachine windows client from here http://www.nomachine.com/download-package.php?Prod_Id=3655
  • Follow installation instructions given here http://www.nomachine.com/documents/client/install.php

Solution 2: Xming

Steps:

• Install PuTTY
  • http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
• Follow steps in this site to install Xming and to set it up to make it work together with PuTTY
  • http://rcc.its.psu.edu/user_guides/remote_display/xming/
    •  Xming
      • http://sourceforge.net/projects/xming/
    • Install additional fonts package for Xming
      • http://sourceforge.net/projects/xming/files/
• Follow steps given in below link to increase the font sizes displayed in GUI through Xming
  • http://aufather.wordpress.com/2010/11/21/increasing-font-size-in-xming-server/
• Problem: Graphical programs are very slow.
  Solution: Enabling “SSH compression” might help if you use a low bandwidth connection. The option is under Connection > SSH in the left menu of PuTTY. (http://doc.es.aau.dk/it_services/software/windows/putty_and_xming/)

Conclusion:

I am using  NoMachine, as Xming(6.9.0.31) was slow even after using SSH compression. And the latest version of Xming(7.5.0.45), which possibly has fixes for slow GUI (http://www.straightrunning.com/XmingNotes/) was not  available for free.
