x2goclient session icons not working
by Will Wagner 23 Nov '16

23 Nov '16

Hello, I have upgraded to 4.0.4.0 on win32. It's a minor thing but if I now set a session icon for a connection it is not displayed and I get blank instead. Is there something I need to do to get this to work? Thanks Will

Some basics questions
by Alain Aupeix 29 Sep '15

29 Sep '15

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 : The host key for this server was not found but anothertype of key exists. An attacker might have changed the default server key to trick your client into thinking the key does not exist yet. For security reasons, it is recommended to stop the connection attempt. Do you want to terminate the connection? Accepting, a new record is added to known host with the second form of record. I noticed that a record created by x2go in a fresh known_hosts is used without problem with ssh Why a such difference ? Will the ip address be updated during a future connection, as the provider changes our public IP for time to time ? 3) Using x2go graphic window, when I choose a profile to connect, x2go first present the box to enter the key, but user password hasn't yet been entered, so we must cancel the key box and the error box, and then enter the user password to have again the key box. This is very curious, and more curious, entering the key doesn't work, x2go always want me to enter the key. In fact, just cancelling this box and the connection is ok. I suppose it's due to known_host, but the way to connect is very strange. Thanks to help me to understand all this curious facts ... curious for my eyes, obviously ;) A+ -- ------------------------------------------------------------------------ Alain Aupeix http://jujuland.pagesperso-orange.fr/ http://pissobi-lacassagne.pagesperso-orange.fr/ ------------------------------------------------------------------------ U.buntu 12.04 | G.ramps 3.4.9-1 | H.arbour 3.2.0dev (2015-09-07 14:28) | HbIDE (Rev.316) | Five.Linux (r143) | Hw.Gui (2492) ------------------------------------------------------------------------

question on linux terminal server publised application
by Trevor Davis 28 Sep '15

28 Sep '15

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
by Jim Lawrence 25 Sep '15

25 Sep '15

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 Jim

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 -- DAS-NETZWERKTEAM mike gabriel, herweg 7, 24357 fleckeby fon: +49 (1520) 1976 148 GnuPG Key ID 0x25771B31 mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

Run x2goDesktopSharing as service
by Alain Aupeix 24 Sep '15

24 Sep '15

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.

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 -- Maciej Sitarz

Disabling sound
by Troels Arvin 14 Sep '15

14 Sep '15

Hello, Setup: RHEL 7 server with x2goserver 4.0.1.19-3.el7. The server's syslog is receiving heaps of messages like this: Aug 26 20:38:03 servername pulseaudio[11023]: [pulseaudio] main.c: User- configured server at localhost:30004, refusing to start/autospawn There's no need to support audio in this setup. So: Can I server-side configure x2go to completely disable sound? -- Regards, Troels Arvin <troels(a)arvin.dk> http://troels.arvin.dk/

Session type: Connect to local desktop -- issues with scaling
by René Genz 14 Sep '15

14 Sep '15

Dear all, at first the situation I encounter: The X2Go server is: a computer with two screens: - operating system: Fedora 22 x86_64 - big screen (22" widescreen): 1680x1050 px - small screen (19"): 1280x1024 px - software: * X2Go server 4.0.1.19-3.fc22 * "KDE Plasma Workspaces" aka KDE5 aka KF5 The X2Go client is: a notebook (Apple MacBook) with the following specifications: - built-in screen: 1440x900 px - operating system: Mac OS X 10.8.5 - software: * XQuartz 2.7.7 * X2Go client 4.0.5.0 The X2Go client software is configured like this: - Session -- Session type: Connect to local desktop - Connection -- Connection speed: ADSL - Connection -- Compression: 4k-png - Input/Output -- Display: custom: 1440x874 Now the problems: If height of screen resolution on X2Go server session is '>= 874 px' you have to maximize window of X2Go client to see. That scales the content of X2Go window and text cannot be read. That can be tested with: 1. log in to X2Go server using above configuration - enable big screen - or use maximum resolution of small screen 2. reconnect with X2Go client to X2Go server If height of screen resolution on X2Go server session is '< 874 px' everything is fine. That means: 1. log in to X2Go server using above configuration 2. disable big screen 3. set resolution of small screen to 1156x856 px 4. reconnect with X2Go client to X2Go server However, the reduced resolution has the drawback of limited overview. The use case is: resuming local session with X2Go. All that is required to reproduce the problem is: - a big screen on the X2Go server that you connect to from an X2Go client that has a screen with smaller screen resolution - the session type must be 'Connect to local desktop' If a native X2Go session (f.e. session type: XFCE) is used this problem does not occur. This does not resume the local session, though. My failed attempts to solve the issues: I tried many different settings in X2Go Client to no avail. I read the documentation and found: http://wiki.x2go.org/doku.php/doc:faq:start#ubuntu_s_and_fedora_s_kde_won_t… which does not make a difference to me. Furthermore, I found: http://wiki.x2go.org/doku.php/wiki:advanced:nx-keyboard-shortcuts ... List of possible ''action'' attributes left up right down which should move the viewport, according to: /etc/x2go/keystrokes.cfg on the X2Go server. I could not get that working on Mac OS X. Even with simplified shortcuts, like F7. I modified the keyboard shortcuts and restart the X2Go server to no avail. There is no other keystrokes.cfg file used. Has someone used the 'move viewport' functionality on Mac OS X? Am I doing something wrong? Shall I file a bug report? The problem is reproducable on 'Mac OS X 10.10' with a screen resolution of 1280x800 px. I tried to reproduce the problem on the same notebook with Windows 7 32 bit. A native X2Go session with XFCE session type works flawlessly. No issues with X2Go client window scaling. However, upon connecting to the X2Go server (KF5 as well as XFCE session) with session type 'Connect to local desktop' an error message appears: VcXsrv windows xserver (X2Go/Arctica Builds) --- VcXsrv windows xserver (X2Go/Arctica Builds) has stopped working Windows can check online for a solution to the problem. [Check online for a solution and close the program] [Close the program] [View problem details] (details snipped) Shall I file a bug report? -- Kind regards, René
