  However, nx-libs performs 3 additional performance improvements:
  
    - nx-libs caches images, so that they do not have to be resent. For example, opening up your "start menu" is very fast the 2nd and 3rd time that you do so.
-   - zlib is generic lossless compression, so it is not well-suited for images. nx-libs acheives better performance by using compression methods such as JPEG (default, lossy) or PNG (lossless.)

    - XCB applications are still partially hindered by round-trips, and nx-libs eliminates more of those round-trips. See  [[https://lwn.net/Articles/343506/|Bart Massey's explanation]] for more info.
  
  The 1st 2 performance improvements also reduce bandwidth usage; which has the effect of improving performance when other users are sharing the same WAN link.

  ==== What is the difference to LTSP? Why a free thin client environment? ====
  
  LTSP requires a high bandwidth on your network. It can efficiently be used in Local Area Networks (LANs) only. 
  
- However, X2Go is not a mere solution for local area networks, but it also allows for the integration of a mobile network into the system. Nomachine’s NX libraries - used by X2Go - enable the transport of whole desktop sessions over a narrow bandwith connection through the internet.

  Further bonuses of X2Go are that you can pause a desktop session and take it to a different thin client for further use.

  ==== Ubuntu's and Fedora's KDE won't resize the desktop to the window size requested by X2Go Client. How can I fix this? ====
  
  This happens because of a package called ''kscreen''. If you encounter an X2Go session trying to launch KDE and this KDE session won't resize properly to your client-side screen or session window size.

- On machines that act as X2Go Server only, it may make sense removing the kscreen package completely. This, however, may have an effect on your X2Go server's plug'n'play capabilities. The ''kscreen'' package handles hotplugging of display hardware. So if your X2Go Server machine is used locally, as well as via X2Go, consider well, if it is ok to remove that package or not.

  For X2Go we suggest disabling the KScreen KDED module (System Settings ->
  Startup and Shutdown -> Service Manager, uncheck "KScreen 2") in the user's profile, since X2Go
  handles resolution
switches for you. To manually change output settings (rotation, enabling/disabling outputs etc) use the KScreen KCM.
