X2Go Seamless Mode
by Mukul Agrawal 29 Apr '16

29 Apr '16

Hello: I am trying to connect from Windows7 machine to Ubuntu (trusty) server. I will like to use X2Go in "seamless" mode ... meaning that if I start a single application, say xterm, on Ubuntu then I want only single xterm window to show up on my MSwin7 computer.Is that possible? X2Go website says it is a Remote Desktop program, but wikipedia says that you have seamless mode and your client also seam to allow it to attach to single application.If somebody can clarify upfront if this is possible or not ... it will save me a lot of time and effort. Thanks in advance! Regards, Mukul ( https://sites.google.com/site/mukulagrawal )

After upgrading Ubuntu 15.10 to Ubuntu 16.04, I can no longer connect using x2go. Trying to use either mate or kde, it appears to try to start and then aborts and goes back to the login prompt. I upgraded x2go server and all x2go software to the most recent on the server side, no help. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

x2go without single point of failure
by Alfi Galfi 22 Apr '16

22 Apr '16

Hello What is recommended way of having x2go without single point of failure? Anybody implemented it? What you used to load balance? x2go broker or some other solution? If x2go broker then how did you eliminated risk of s2go session broker server failing? What solution did you used?

loadbalancing with x2go broker
by Alfi Galfi 20 Apr '16

20 Apr '16

Hello Since on http://wiki.x2go.org/doku.php/wiki:advanced:x2gobroker:loadbalancing site isn't too many information about load balancing I have question how exactly this load balancing is working? Connection client <-> broker and broker <-> server is up till client disconnect from server or this connection exist only on time of creating connection between client and server? How many clients can be handled by broker in same time? Is it possible to use x2go for around 1k clients connected simultaneously when every one of them generate pretty big network traffic? Or should we consider other load balancing solution? Usage of how many x2go servers is recommended for this number of users? Greets, Gafi

Screensaver not kicking with MATE
by Daniel Berteaud 19 Apr '16

19 Apr '16

Hi. I'm running MATE Desktop 1.12.1 on a CentOS 7.2 server, and access it using X2GO. Mostly everything is working great, except that the screensaver is not kicking. I have: > gsettings get org.mate.session idle-delay 1 > gsettings get org.mate.screensaver lock-enabled true But when loging in using X2GO, it looks like mate-session doesn't detect inactivity at all. Neither the screensaver, nor the locking works. I'm running this in a thin client setup, so screensaver/session locking is quite important. Anyone else have the same issue ?

CUPS-X2GO Local Printer /usr/lib/cups/backend/cups-x2go failed
by Madog 11 Apr '16

11 Apr '16

Hi All: I'm getting a printing error in an x2go instance that has worked for a long time, and am hoping to get some help. The error that shows up in the client side (windows) print window is: CUPS-X2GO Local Printer /usr/lib/cups/backend/cups-x2go failed The server where I'm running x2go ran out of disk space before a fix got done, and am wondering if that munged a key or set of files, as am guessing this is something to do with printing authentication (it's a single node x2go server and x2go printing). I've tried re-installing the x2go printing (cups-x2go, x2goserver-printing). I've copied in a "cupsd.conf" from another working instance. The /var/log/cups/error_log says: W [11/Apr/2016:12:15:14 +0000] Please move "SystemGroup lpadmin" on line 3 of /etc/cups/cupsd.conf to the /etc/cups/cups-files.conf file; this will become an error in a future release.

I'm having a lot of trouble getting a gstreamer based video player to work under X2Go. First off it looks like Xv is not supported. Is that something that ever will be? Next thing I'm seeing with the parole player is that the video frame goes black when I pause it. I'm also trying to use the fluendo gstreamer codecs and seeing segfaults (apparently in the fluendo code) when using dragon player to watch videos. I'm running with current nx-libs git from https://github.com/ArcticaProject/nx-libs. EL7 server and client. Any ideas or suggestions?

firefox freezing by right-click
by olafs6＠gmx.de 22 Mar '16

22 Mar '16

Hello! I installed the x2goclient in puppy (tahr). When I start a session on my x2go server (Ubuntu 14.04) with this client I have problems with firefox 42.0: - Right-click in Firefox (link, empty space, ...) causes somewhere that the browser for about half a minute to freeze completely -> If I click when he is working again, in the opened context menu on any point, the browser freezes again for the same time again. - Click the top right on "Organize Bookmarks" also causes freezing The whole happens only when using under puppy. Even with use of another x2go server (also Ubuntu 14.04 but Firefox 41.0.1) of puppy from there the same mistake. This happens also when Firefox is directly called x2go, ie without the favored else from me LXDE. When I call a x2go session with a client software on other distributions (Windows, Ubuntu, OpenSuse), the problem does not occur. What here comes with puppy in the way? Greeting, Olaf

x2go to LXC containers
by Michael Eager 15 Mar '16

15 Mar '16

I'm running into a problem using x2go with LXC containers. I've been using x2go to connect to an LXC container for some time with no problem. I've created a new container on the same host and I'm able to connect to it using SSH. I can also connect to the new container with x2go, as long as I'm not connected to the old container. If I start two x2go sessions at the same time, both fail. At least some of the time, I am no longer able to connect using SSH and need to restart the container. -- Michael Eager eager(a)eagercon.com 1960 Park Blvd., Palo Alto, CA 94306 650-325-8077

Customize Published Applications menu layout
by Gabriel Machado 15 Mar '16

15 Mar '16

Hi people! I've installed x2go on a server i'm configuring anda i'm impressed in how good it works! I would like to have all applications on my Published Applications menu on the top level, but can't figure how! I've tried to copy the .menu file to the /etc/xdg folder but it didn't changed a thing! It seems only to use default categories from freedesktop. Is it a hard coded feature or there is a file to change its layout? Thank you! Gabriel Fonseca.

Sluggish response
by Timo 11 Mar '16

11 Mar '16

Hi, X2Go Client v. 4.0.5.0 (Qt - 4.8.6) GeForce GT 430 1GiB Driver 361.28 x2goserver 4.0.1.19-0~1064~ubuntu14.04.1 Ubuntu 14.04.4 local and remote ADSL 7/1 Mbps I have used x2go quite a long time to work from home. It have been working very nicely. But recently it have started to have very slow resume and sluggish response. It may take minutes to construct all the windows in the session at the resume and unminimize. Local desktop goes very sluggish as well. I have a lot of application windows open and using full screen session. I have investigated a little an noticed symptoms like this: When I resume the session and get a chance to minimize it, I see that memory usage of graphics card have shot to 100% and Xorg takes 100% CPU. This happened just this morning. Then I launched Thunderbird locally and saw that the memory usage dropped to 10% and everything started to behave normally again. But then I suspended the x2go session, resumed it again and the same slugginesh and symptoms came back. I have tried ADSL and WAN connection but didn't see any difference. What should I try next? Can I somehow force Xorg/x2go not to commit all graphics memory or something? -- Timo

x2go overwrites LD_LIBRARY_PATH
by Thomas Stephan 11 Mar '16

11 Mar '16

Hi, I am using x2go to connect to machines running Ubuntu 14.04.3 LTS. I had trouble running commands that rely on finding libraries via the environment variable LD_LIBRARY_PATH. LD_LIBRARY_PATH is set in a script in /etc/profile.d because this is a system wide configuration and it needs to be performed once per login. Using ssh to remote login, LD_LIBRARY_PATH is correct: echo $LD_LIBRARY_PATH /usr/lib/fsl/5.0 When I login using x2go, LD_LIBRARY_PATH seems to be reset and contains only the entries regarding x2go: echo $LD_LIBRARY_PATH /usr/lib/nx/X11/Xinerama:/usr/lib/nx/X11 My guess is that there is probably an error in /usr/bin/x2goruncommand, along these lines: test -n "$LD_LIBRARY_PATH" && \ LD_LIBRARY_PATH="$NX_XINERAMA_LIBS:$NX_LIBS:$LD_LIBRARY_PATH" || \ LD_LIBRARY_PATH="$NX_XINERAMA_LIBS:$NX_LIBS" "$X2GO_LIB_PATH/x2gosyslog" "$0" "debug" "exporting LD_LIBRARY_PATH=$LD_LIBRARY_PATH" export LD_LIBRARY_PATH But I can not see why it is that my path only contains $NX_XINERAMA_LIBS:$NX_LIBS, and not $NX_XINERAMA_LIBS:$NX_LIBS:$LD_LIBRARY_PATH. Thank you for your help!

x2go-client depends on xorg-xauth?
by Bruno Pagani 09 Mar '16

09 Mar '16

Hi, I’m currently using x2go-client on a (Arch) Linux desktop (connecting to a Ubuntu x2go server, on which I’m not admin), and I’ve found out that it apparently needs xorg-xauth to work properly. Is that indeed the case? Because I can’t found a list of dependencies outside of nx, qt4 and libssh, and the current ArchLinux or Fedora packages (for instance) do not depend on it. Thanks, Bruno P.S.: Since I’m not suscribed to this list, please be sure to keep me in CC when you answer this. ;)

Sessions and pids
by Karres, Dean 07 Mar '16

07 Mar '16

Hi, I am looking for advice. We have a few x2go "servers". We have customers that use the client on laptops to connect to the servers and do what they do. I need to account for the time they have active x2go sessions. We have tools to get user login/out data. The behavior we are seeing is as follows: 1. Customer-A logs in via the pc client. 2. Customer-A does or starts work then literally closes the laptop and walks away. 3. After the default SSH timeout his "connection" ends but the x2go session continues. 4. Later, the laptop is reopened and the x2go session is resumed. 5. ... repeat... I have put small scripts in all of the "extensions" sub-dirs to report the activity. They really just report the result of "/usr/bin/x2golistsessions". * After #1 I see the pre-and post-start scripts but they are NOT reporting a PID number. * After #2 I can see our normal logout process run after the ssh connection timeout. * After #4 I see our normal login process run due to the new ssh connection; and I see the pre and post-resume scripts run and they DO have PIDs. I can imagine that the "pre-start" script hook might not have access to a running PID yet but is there any way for the post-start script to get the PID? I could craft a special version of our audit tools to deal with a numeric PID in the pre or post-start scripts and treat it like a console or ssh "login". I suppose I could craft it to use the x2go sessionID but that will cause a lot of other changes in out existing audit tools. Thanks

SSH key generation in Windows
by Sébastien Ducoulombier 03 Mar '16

03 Mar '16

Hello, I am considering restricting access to my X2Go servers : I'd like to disable password authentication. I need all my X2Go client users to generate their own SSH keys and transfer the public part to the server. I wrote a simple guide for Linux and Mac users, but I still miss Windows support, since I do not have windows systems around me. I found http://wiki.x2go.org/doku.php/wiki:advanced:authentication:passwordless-ssh… Does that wiki documented procedure work with XP, Seven and W10 ? -- Sébastien

General screen redraw and performance issues with x2go and CentOS 6.7
by hyral.sacai 25 Feb '16

25 Feb '16

Hello, I've installed x2go on the following platform: CentOS 6.7, KDE x2goagent: 3.5.0.32 x2goserver: 4.0.1.19 x2goserver-compat: 4.0.1.19 x2goserver-extensions: 4.0.1.19 x2goserver-fmbindings: 4.0.1.19 x2goserver-printing: 4.0.1.19 x2goserver-pyhoca: 4.0.1.19 x2goserver-xsession: 4.0.1.19 I access the server using the following: Client 1: OS X El Capitan (Version 10.11.3) Mac x2go client (latest version) LAN connection (ping to server < 0.4 ms) Client 2: Windows 10 Pyhoca-GUI (latest version) WAN/internet (ping to server <15 ms) Under both clients, I sometimes experience a tremendous amount of unresponsiveness (more than a minute) where I cannot interact with the screen. Sometimes I get so impatient that I just terminate the session and start a new one. Another issue that happens much more frequently is the incomplete redrawing of my screen, especially in EDA tools (Cadence Virtuoso). When zoom in/out of a design on screen, it becomes a scrambled mess. I have to hover my mouse over parts of the screen that did not redraw (sorta like using paint brush or an eraser to reveal the image beneath). Running the same applications remotely through ssh/x11 tunneling, I have not encountered these issues (so far). But when x2go does behave well, I prefer it's experience especially when dealing with multiple sessions (suspending, terminating them) and how the windows behave. A more interesting note, I installed x2goserver on an older server running CentOS (5.11) and the performance is very good. I do not encounter the aforementioned problems. One difference I noticed in my logs is that the new server (on CentOS 6.7) uses a deprecated QDBusConnectionInterface, while the older server does not show this in the log. In any case, I included the '.xession-x2go-errors' log file below from the CentOS 6.7 server. Any help would be greatly appreciated. Best, Hyral .xsession-x2go-errors log after clearing all sessions and start a new one: > tail -f ~/.xsession-x2go-errors > startkde: Could not start ksmserver.

Black screen after pxe boot
by Olaf 22 Feb '16

22 Feb '16

Hello! While TCE boots via pxe (showing the progress bar) it uses only 25% of the screen (1920x1080) in the upper left corner. After booting the screen is black and displays a small "x" for the pointer. Other PCs / clients work, so I suspect that there is a problem with the video driver. Does somebody has any idea? Ubuntu 14.04 Client: Fujitsu FUTRO S550, ATI Radeon X1250 Greetings + Thanks, Olaf
