msx As a n00b to x2go I was unable to log to my x2goserver until users @arw and @siretart on the irc channel helped me to debug my issue, creds go to them :)

 +==== Is there an X2Go server daemon/​service that needs to be started? ====
 +
 +Strictly speaking, the only daemon/​service that needs to be running is the SSH daemon. If users can connect to your server via an SSH client, then they should be able to connect via X2Go Client or PyHoca-GUI/​PyHoca-CLI.
 +
 +There is an X2Go server init script called "​x2goserver"​. Depending on your Linux distro, there may be systemd service called "​x2gocleansessions.service"​ instead. It is highly recommended that this service be enabled. It handles cleaning up sessions.
 +
 +==== Does X2Go support Wayland? ====
 +
 +So long as X2Go uses the NX protocol exclusively for remote display and keyboard/​pointer input, X2Go cannot support Wayland or Mir. (Audio and file/​printer sharing are handled by separate protocols.) This is because NX works with the X11 protocol, rather than using an entirely separate protocol like SPICE and VNC do. (NX improves X11 performance by caching the X11 traffic, compressing it, and eliminating the X11 "​round-trips"​.)

 +==== Does X2Go support Mir? ====

 +See the answer to the last question.

-==== Is there a MS Windows Client? ====+==== You have 3 clients. Which client should I use? ====
  
-Yes, you can find it on our [[installation]] ​(FIXMEpage.+If you are in doubt, pick the regular X2Go Client ​(x2goclient). It is the most widely used and tested.
  
-==== Is there a MacOS Client? ====+  * The regular X2Go Client ​(x2goclient) is optimized for thin client & single-session usage, but can still be used on any desktop/​laptop computer. 
 +  * PyHoca-GUi is optimized for users who want to connect to multiple sessions at once, and already know how to use X2Go. For example, a sysadmin administrating multiple servers. 
 +  * PyHoca-CLI is launched via command-line args; similar to vncviewer or rdesktop/​xfreerdp. It is also suitable for connecting to multiple sessions at once.
  
-Yes, you can find it on our [[installation]] ​(FIXME) page.+==== Is there a MS Windows Client? ====

 + 
 +==== On Ubuntu 12.10 & later, Unity sessions fail to start ==== 
 + 
 +Unfortunately,​ Unity on Ubuntu 12.10 will not work with X2Go in the foreseeable future. 
 + 
 +This is because Ubuntu 12.10 and later no longer offer Unity-2D; they only offer regular Unity. When selecting Unity in an x2go client, you are actually selecting Unity-2D. However, regular Unity requires 3D support. X2Go cannot support 3D because X2Go is currently based on the NX libraries, which do not support 3D. 
 + 
 +One workaround is to remain on Ubuntu 12.04 LTS, which is supported until April 2017. Another workaround is to install one of the other desktop environments that is listed in your X2Go Client. You can do so without uninstalling Unity. Follow [[http://​askubuntu.com/​questions/​65083/​what-different-desktop-environments-and-shells-are-available|this link]] for instructions on installing other desktop environments.
