In x2goclient Session Management


      If you bring up the x2go client session manager and then click on a
particular session, Delete is grayed out and one can no longer delete a 
session.

      I couldn't find an alternative method in the client and just hand edited
the x2goclient/sessions file, but I can't believe this was the intent.

Switching between Desktops


      I had commented earlier about the behavior of X2Go verses NX when it came 
to switching Desktops when in a session.  That X2Go would pass the CTRL + ALT + 
-> and CTRL + ALT + <- keys to the remote application rather than allowing the 
local switching of desktops with those keystrokes.

      It was suggested editing keymaps, but actually the solution turned out to
be much simpler.  When you create a session you can specify a full screen,
a window of some size, or the whole display.

      If you specify a full screen those keys are passed to the remote and you
can't switch desktops locally except by doing CTRL + ALT + M to minimize the
x2go session and then switching desktops.  And that's a pain if you are working
on a bunch of servers and have to switch frequently as if often the case for 
me.

      However, if you specify use the whole display rather than full screen
then the ALT + CTRL + -> and ALT + CTRL + <- arrows are acted upon locally
allowing the easy switching between local desktops (with X2Go sessions to
various servers).

      What would be very nice is if there were a way to switch that setting on
the fly.  With the Remmina NX client, you have a little one-pixel pull down at
the top of the screen, and if you pull it down there is a keyboard symbol.
If you push the symbol it visually depresses, then all your keystrokes go to
the remote computer, if you undepress it, the CTRL+ALT+ arrow keys are acted
upon locally.

Sound Troubleshooting


      I just installed Ubuntu-Mate 15.04 on a new server, installed pretty much 
all the x2go packages, but for some reason sound does not work over x2go on 
this machine.  The same client receives sound fine on another server with 
Ubuntu-Mate 15.04.  Both have the same version of x2goserver, 
4.0.1.19-0~1064~ubuntu15.04.1.

      One significant difference is the server that works started life as an
earlier version of Ubuntu, 14.04 I think and then was upgraded to 14.10 and
then 15.04 in place where as the new server was installed from a Ubuntu-Mate 
15.04 DVD made from the ISO that is available on ubuntu-mate.org.

      Any suggestions as to where to start troubleshooting the server?

Some basics questions

Hi,

After some try, and a few problems, I made my connections possible, but
I have some questions:

1) On the machine where I install ssh, I always disable, for security
reason, the possibility to connect using the user password.
After some unsuccessfull tries, I saw that to be able to connect, I must
enable the connection with the password (on server side).

Is-it normal ? I don't like a simple password protection. I prefer
public key.

2) In my first tries, I had a curious message, and it was impossible to
connect. The problem was in known-host.
Deleting it done the trick, but analysing the difference between the
previous and the one generated during x2go connection, I say a
difference between records.

When using ssh in console to connect, the record looks like this :

|1|TaiGrqxL3igpSgVZ4Y6WahmwxEw=|M6tIFGIbg/ZQJI4HTLwLC55AAeY=
ecdsa-sha2-nistp256 AAAAE2VjZHNhLX

When connecting with x2go, looks like that:

[192.168.1.53]:22461 ssh-rsa AAAAB3NzaC1yc2E .....

Now, with my last tests, if I have a first form of record, I have this
message :

question on linux terminal server publised application

Hello ... I would like to know if it's possible to connect to the broker and have someone launch a linux published application without having to install any type of x2go client (web client or local client).  Maybe via HTML5 or ideally Java or something else which will run the application in a seamless window.

x2go used only on remeote sessions

Hi All: 

Given that X2GO only works with 2D desktops so the desktop must be something like LXDE, XFCE or MATE. 

Can it be configured so that a X2GO remote session will initiate a, for example, MATE desktop session for the
remote duration? (Or is this already the case?) 

If not here is how a it works with XRDP and Ubuntu 14.04 (and greater), how to setup MATE fall-back session
software for managing remote access. 

https://www.youtube.com/watch?v=L1ay7toiJ6k 

Can this be done, or is already being done with X2GO? Any help would be greatly appreciated. 

Thanks

Run x2goDesktopSharing as service

Hi,

I'm a new user.
I'm under Ubuntu 12.04 with gnome-shell and I have installed x2goclient.
With the update I have now 'X2Go Client v. 4.0.5.0 (Qt - 4.8.1)'
One another computer I have installed x2goserver and x2goDesktopSharing

Is-it possible to launch x2goDesktopSharing as a service when launching
the system (same as x2goserver), to be able to disconnect of the user
and reconnect to another.

For now, disconnecting (:0) kills the nx connexion.

I have other troubles, but I will open a new thread.

Thanks
A+

Launchpad cleanup

Hi all,

on request of the Ubuntu MATE team I have enabled automatic builds for  
X2Go packages for Ubuntu 15.10.

Builds are pending and should appear during the day.

Furthermore, I have removed packages for all non-supported Ubuntu  
versions from the X2Go PPAs (i.e., packages for Ubuntu 10.04 (lucid)  
and Ubuntu 14.10 (utopic).

light+love,
Mike

x2goclient connection fails with 'setterm: $TERM is not defined'

Hi x2go users,

After recent update to x2goclient 4.0.5.0-2.fc22 I'm unable to connect 
to my x2go server.

Error message:
Connection failed. setterm: $TERM is not defined.

Steps to reproduce:
1. Upgrade x2goclient to 4.0.5.0-2.fc22
2. Just try to connect to x2go server

When I downgrade back to 4.0.3.2-1.fc22 everything is fine. Any ideas?
I thought about opening a defect, but maybe it's something wrong with 
the setup of my server?

1. The client machine's OS: Fedora 22 x86_64
2. The client machine's version of X2GoClient: 4.0.5.0-2.fc22
3. The server's OS: Arch Linux
4. The server's version of the x2goserver package: 4.0.1.19-2
5. The server's version of the x2goserver-xsession package: No such 
package installed or found in repos
6. The server's version of the nxagent package: 3.5.0.32-1
7. The server's version of any other relevant packages: None
8. Any relevant settings in X2GoServer: None

Long log from x2goclient --debug can be found here: 
http://pastie.org/10425302

Best regards

Broker with multiple hosts on different ports

Greetings,

I am setting up x2gobroker with multiple backends, and while I can change the port that they all use for ssh, I would need to set a different port per host to NAT them to the same public IP . 

Is there any way to do this at present ? where can I look for documentation?

Problems with x2go

Hi,

I'm a long-time VNC user trying out x2go after many people have recommended it, but I can't get it to work well
when trying to set up x2go-sessions from Windows, so if anyone can help me out, I'd be grateful.

Issue 1:
First I tried "X2Go Client" and that one just keeps crashing on me. I only need to enter the "session
preferences" dialog and as soon as I press ok (independent if I change anything or not), the program
crashes and Windows tells me "x2goclient.exe has stopped working". Similar crash if I try to start a
session. This with X2Go Client v. 4.0.5.0 (Qt - 4.8.6) on Windows 7. I tried an older version 4.0.2.x which
did not crash so there seems to be something off with the most recent version. Known issue?

Issue 2:
So I installed PyHoCa-GUI instead. That one is stable and mostly works. But when I choose "custom command"
as the session, it refuses to run any command with an absolute path and only accepts things in places like
/usr/bin/. Perhaps it is some path-issue, but it also does not accept things in /home/myname/bin/, which
is in my $PATH from the shell. Note: I'm using zsh as my login shell. Is this a bug or am I not supposed to be able
to run things with absolute paths? (note: I have double-checked file permissions and the things I'm
pointing to under /home are +rw for everyone). I don't want to have to put my session script in /usr/bin/

Question 1:
No matter if I use the "X2Go client" or "PyHoCa-GUI", I don't get the keyboard behavior I would like. Using
VNC, it will just map each keypress from Windows and pass those symbols into the server, which is important
since I use a custom keyboard definition. That doesn't seem to work with x2go as I get pc104/us both if I tell
it to "do not set" or "automatically detect". And if I choose "use custom keyboard", I can only select a
"standard" keymap, I have no idea how to tell it to use a custom keymap.
Is it so that x2go can't handle user-defined keymaps and only handles standard keymaps?

Question 2:
Font handling. I don't get the same set of fonts when I run through x2go as I get when using VNC as some
directories are missing from the font path. Trying to manually add those from inside the x2go session
("xset +fp /some/path/that/works/in/vnc/") gives an error. Is there something special with the font
handling in x2go that is not compatible with all X11 fonts? Running the same xset command from inside VNC
succeeds without problem on the same machine.

Version info: the server is running on a Ubuntu machine (14.04) with these x2go libs:
x2goagent: 3.5.0.32
x2goserver: 4.0.1.19
x2goserver-extensions: 4.0.1.19
x2goserver-xsession: 4.0.1.19

TIA,
  Chris
