====== FAQ ======

For those who want to find reasons for certain behavious of X2Go, read here: [[http://wiki.x2go.org/doku.php/wiki:development:debugging|How To Debug or Troubleshoot your x2go installation]]

===== Server FAQ =====

==== Is x2go compatible with nomachines NX or freeNX? ====

No even though X2go uses the same libraries, X2go aims for an even greater integration into the Linux environment. It’s not possible to use NX client to log on to a X2go server and vice versa. 

==== Can I install FreeNX and x2goserver on one system? ====

Yes - the NX libraries of X2go are actually the most recent versions of NXv3 libs available. NoMachine has dropped the NXv3 development branch completely and closed source on NXv4 :-(.

Due to these circumstances in the future the X2go project will be upstream source for NXv3 libs for quite some distributions like Debian or Ubuntu. 

In former times the NX libs shipped with X2go installed into an X2go'ish location so that they would not interfere with the original NX libraries. 

Nowadays the NX libs shipped with X2go work as a replacement for the NXv3 that are not maintained by NoMachine anymore.

(This FAQ article has been written by Mike Gabriel, if someone does not agree with the given information on NoMachine, please be so kind to contact me, so that we can discuss it and possibly correct errors in the given information).

==== 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. 

==== What are the packages x2goserver-home and x2goserver-one for? ====

Both packages (x2goserver-home, x2goserver-one) are obsolete as of April 2011. They have been removed from the current .deb repositories and they should not be used anymore (in fact they break your system). On .deb based system they will automatically be uninstalled with an update of the x2goserver package.

x2goserver currently does neither have any group membership restriction any more as former versions had. This may well be re-introduced, though, if someone picks up work on that. 

The obsolete x2goserver-home package added all known users on the server system to the group x2gousers which made some people nervous when testing X2go on production systems :-/. For this reason we have dropped the auto-adding of users to groups in Apr 2011.

==== Do I need a postgres database to run x2goserver? ====

No. The postgres database is only needed if you are planing to use more than one connected server (server array). By default x2goserver installs with SQLite support enabled. To set up X2go with PostgreSQL as DB backend you have to edit the x2goserver's configuration in /etc/x2go. 


===== Session FAQ =====

==== How do I change the keyboard layout? ====

Although some tools (e.g. Gnome Keyboard Indicator) might have trouble changing the layout, you should be able to change the keyboard layout using setxkbmap.
<code>
setxkbmap de
setxkbmap us
</code>

==== How do I customize font sizes in X2Go sessions? ====

Some people have asked for font size customizations in X2Go session windows. Please use the DPI value in the session setup to customize font sizes within your X2Go sessions:

  * 70 DPI -> quite readable fonts
  * 90 DPI -> the default font size
  * 120 DPI -> miniature font size

==== File and folder sharing has stopped working since Apr 2011 (approx.). Why? What can I do about it? ====

Add users that shall be granted X2go file and folder sharing functionality to the fuse group on your system. For user foo this may look like this at the command line:

<code>
$ adduser foo fuse
</code>

===== Client FAQ =====

==== Is there a MS Windows Client? ====

Yes, you can find it on our [[installation]] (FIXME) page.

==== Is there a MacOS Client? ====

Yes, you can find it on our [[installation]] (FIXME) page.

==== Can I use x2goprint with Windows Clients? ====

To set a print target, you'll need ''x2goclient''. For example you can use the RDP tunneling feature of X2go.

===== Known Issues =====

==== Can't login to x2goserver with an ECDSA key ====

At this time libssh, the ssh library used by x2go is unable to work with an ECDSA key.
However you may use an RSA key -if you need to- or go with the ssh default authenticating method using the remote user's password.
