  • In Remote tab select Style: Same as Local. Close the dialog window and restart the PC

        
 

How to login from another PC running Ubuntu

  • Click Options at the lower left corner of the login screen

  • Select "Remote Login via XDMCP"

  • On the dialog window, type in the host name or ip of the fast computer you want to login to and make your slow PC run fast
