The above versions of Ubuntu's default user environment, Gnome(Ubuntu), use hardware acceleration to render the graphics. Therefore, when remotely connecting with Xmanager, you may not be able to access the the desktop user environment or if you are able to connect, it will run very slowly.
As such, if you are using the above Ubuntu versions, you will have to use a different desktop user environment.
...
Install a new user desktop environment (Xfce)
Code Block $ sudo apt-get update $ sudo apt-get install xubuntu desktop
Apply the new user desktop environment by restarting the XDMCP daemon
Code Block $ sudo service lightdm restart
- After connecting with Xmanager, select the Xfce or Xubuntu session from the login screen
