+ | ==== Why are you using the terms " | ||
+ | |||
+ | Basically: | ||
+ | |||
+ | - That is the term that was always used. | ||
+ | - Libraries are created also from the source package. | ||
+ | - Those libraries define the NX protocol. | ||
+ | |||
+ | Note that originally, " | ||
+ | |||
+ | - nxcomp | ||
+ | - nxcompext | ||
+ | - nxcompshad | ||
+ | - nxproxy | ||
+ | - nxagent | ||
+ | - nxauth | ||
+ | - nx-X11 | ||
+ | |||
+ | Only the 1st 3 are libraries. | ||
+ | |||
+ | Having separate tarballs made maintenance more difficult, so they were combined into one as the X2Go project started redistributing them. | ||
+ | |||
+ | ==== Why not just use X11 forwarding over SSH? This is what Keith Package recommended. ==== | ||
+ | |||
+ | You are probably referring to the [[http:// | ||
+ | |||
+ | It is true that X11 forwarding' | ||
+ | |||
+ | 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, | ||
+ | - XCB applications are still partially hindered by round-trips, | ||
+ | |||
+ | 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. | ||
+ | |||
+ | ==== Why Am I told to enable X11 forwarding with X2Go? I thought that X2Go uses nx-libs instead of X11 forwarding! ==== | ||
+ | |||
+ | The simple answer is that the OpenSSH server treats the connection differently (in such a way that degrades nx-libs performance) unless X11 forwarding is enabled. | ||
