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? Thanks. -- Orion Poplawski Technical Manager 303-415-9701 x222 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion(a)nwra.com Boulder, CO 80301 http://www.nwra.com

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

Hi everyone, i'm running an x2goserver on a 32bit Kubuntu Trusty Tahr Vmware workstation 9 vm. I have the following debs installed there: ii x2goagent 2:3.5.0.32-0~668~ubu all ii x2goclient 4.0.5.0-0~1099~ubunt i386 ii x2goserver 4.0.1.19-0~1064~ubun i386 ii x2goserver-extensions 4.0.1.19-0~1064~ubun all ii x2goserver-xsession 4.0.1.19-0~1064~ubun all The client is my laptop running 64 bit Kubuntu Trusty Tahr with an extra monitor connected. It has the following packages installed: ii x2goclient 4.0.5.0-0~1099~ubuntu14. amd64 Everything is working as expected but i cannot get any of the methods described in http://wiki.x2go.org/doku.php/doc:usage:multi-display to work. When i stretch my x2go client window over multiple monitors the server sees it as on big screen. It does so regardless of whether i check Xinerama extension or not. My laptop has Xinerama enabled. How would i go about getting this to work? -- Grüße/Regards Mario

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. ;)

Reconnect to session
by Michael Eager 09 Mar '16

Hi -- I'm trying to reconnect to an existing session using the x2goclient GUI, or using the pyhoca-cli command line. This does not work. I'm also not able to suspend a running session. When I use x2goclient to re-connect to a server, the old session is listed as running.

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

unable to open database file

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.

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?

I did all the stuff about installing the keyring etcetera as described on the webpages, but if I do an apt-cache search x2goserver the thing is not listed. I seems the package x2goserver is missing from the armhf distribution. If I open http://packages.x2go.org/debian/dists/jessie/main/binary-armhf/Packages in my browser x2goserver is not listed there. I am doing something wrong? Or do I misunderstand something? As a check on myself I did the whole exercise on my laptop running debian jessie and there it works fine, but then that is the amd64 distribution. as illustration about what happens here is some terminal output from the banana pi: frans@pibanan ~ % uname -a Linux pibanan 3.4.108-bananian #2 SMP PREEMPT Thu Aug 13 06:08:25 UTC 2015 armv7l GNU/Linux frans@pibanan ~ % apt-cache search x2goserver x2goserver-compat - X2Go server daemon scripts (backwards compatitbity to old client versions) x2goserver-extensions - X2Go server daemon scripts (extensions) x2goserver-fmbindings - Generic (freedesktop-based) file manager bindings for X2Go x2goserver-printing - X2Go server daemon scripts (printing) x2goserver-pyhoca - X2Go server daemon scripts (add-ons for pyhoca client) x2goserver-xsession - X2Go server daemon scripts (Xsession runner) frans@pibanan ~ % and the same commands from a terminal on my laptop frans@dx200 ~ % uname -a Linux dx200 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt20-1+deb8u3 (2016-01-17) x86_64 GNU/Linux frans@dx200 ~ % apt-cache search x2goserver x2goserver - X2Go server daemon scripts x2goserver-compat - X2Go server daemon scripts (backwards compatitbity to old client versions) x2goserver-extensions - X2Go server daemon scripts (extensions) x2goserver-fmbindings - Generic (freedesktop-based) file manager bindings for X2Go x2goserver-printing - X2Go server daemon scripts (printing) x2goserver-pyhoca - X2Go server daemon scripts (add-ons for pyhoca client) x2goserver-xsession - X2Go server daemon scripts (Xsession runner) frans@dx200 ~ % could anybody help? thanks in advance, Frans van der Vat

Encryption Algorithms
by Robert Dinse 19 Feb '16

19 Feb '16

Is there anyway to specify which encryption algorithms x2go allows or tries to use? I have a problem where I've got the latest and greatest installed, Ubuntu 15.10, latest client, etc. I have customers with old Ubuntu like 12.04LTS, and they can't connect with their old x2go clients because it can't establish a compatible set of encryption. I'd like them of course to upgrade their OS and software and they do understand the reason old algorithms have been blacklisted is that they are insecure, but they are resistant to doing so for a variety of reasons, hardware that doesn't work well or at all with modern releases, legacy software they want to keep running, etc. So I'm looking for a fix that will allow them to connect with their antique software. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

How to change OS X x2go client keyboard shortcuts?
by Alex Coventry 10 Feb '16

10 Feb '16

In the OS X client, Control-Option-F toggles fullscreen. I would like to pass the chord through to the server, because C-M-F in emacs is forward-sexp. Is there an easy way to do that? I've tried putting a file at ~/.x2go/config/keystrokes.cfg with the following contents: <!DOCTYPE NXKeystroke> <keystrokes> </keystrokes> However, Control-Option-F still results in toggling fullscreen. Stack Exchange question about this. <http://superuser.com/questions/1037305/how-can-i-change-x2gos-keyboard-shor…> Best regards, Alex

optimizing x2go resource use
by Jordan Poppenk 09 Feb '16

09 Feb '16

Dear X2Go users, I'm working on optimizing resource use of a largish-number of sessions. I made a few optimizations, e.g., disabling xscreensaver, but there were a few things I couldn't figure out on my own. Is someone here able to help? 1) Does X2Go do its desktop rendering on the server's GPU? That is, in building a server to support X2Go sessions, should I buy a fancy graphics card when trying run many sessions; or alternatively multiple core CPU's? If GPU matters, does it matter whether the card is of the GeForce vs. Quadro variety? 2) Does reducing colour depth have any substantive effect on the CPU/GPU/bandwitdth burden on the server? My users don't really need more than thousands of colours. I know this and JPEG quality can be adjusted client-side, but when I played with these settings, it didn't seem to impact server-side bandwidth (which continued to hover around 1Mbit per client even with just a few colours). Should I be adjusting this in the LXDE startup settings instead? 3) Is it fair to estimate that I need about 1Gb of RAM per client (just to load the desktop) just to load LXDE as the desktop?

x2goagent memory usage (leak?)
by Stefan Seidel 09 Feb '16

09 Feb '16

Hi, I have used x2go for a while now and I observed that on the server, the process x2goagent is increasingly using more memory over time. I starts out with something like 300 MB, and rises steadily. I leave the session disconnected (suspended) when I leave work (usually I just shut down the client PC). The next day, memory usage is much higher, roughly 1GB. And this continues until the process uses too much memory and gets killed (or other processes get killed first). The server: - Ubuntu 12.04, CPU i7-860, RAM 24GB, 32 bit kernel (with PAE) ~> x2goversion x2goagent: 3.5.0.32 x2goserver: 4.0.1.19 x2goserver-extensions: 4.0.1.19 x2goserver-xsession: 4.0.1.19 Anyone observing a similar behaviour? Is it important whether I do x2gosuspend-session or just kill the client? Stefan

X2Go speed (Gb LAN) vs. pure X
by Stefan Seidel 02 Feb '16

02 Feb '16

Hi, I am currently testing X2Go to be a replacement for our (1GBit/s) LAN XDMCP setup. I have set up a Jessie X2Go-PXE server VM with a Jessie chroot env. It is working in principle, I can get a connection and the advantage of session suspend/resume is great. (Although I had to remove the pulseaudio startup from the x2gosessiond to make it work.) However, I have two problems: 1. How can I set client-specific X11 options? We have clients with complex multi-monitor setups. Xinerama doesn't seem to be working, either, once I have set the screens on the client (using Ctrl+Alt+F1, then xrandr) and connect, the X session only sees one "big" screen. 2. Speed: for small screen updates (menu items etc.) - I would guess < 10k pixels - X2Go is very speedy and responsive. For anything larger (Google Chrome being a serious offender, as it always updates the whole rendering area) it is much slower. Even just scrolling in Firefox is "laggy". Pure X is much faster for these large screen updates. I have tried various settings, 4k-jpeg is almost acceptable speed-wise but still not fast enough. Test setup: X2Go-Server: Core i7-860 (4x2.8GHz), 24G RAM X2Go-PXE: VM with 4GHz AMD, 2G RAM Clients: Pentium D 2.8GHz, 512MB RAM, nVidia Dual-DVI graphics (model 6200 IIRC) with 2 1600x1200 monitors -> 2400x1600 total screen area. Clients use NOUVEAU and report Chipset: "NVIDIA NV44" Thanks in advance for any hints, Stefan

Paid Support?
by James M. Pulver 29 Jan '16

29 Jan '16

I'm trying to see if there's a contact for general support on using X2Go, and maybe feature bug fixing. The linked sites on the Wiki don't seem to have an English version, and there's no obvious contact link or e-mail address. I'm mostly looking for a ballpark idea of cost. (i.e. $xx per hour or $xxx for an estimate for work) I'm probably looking at issues on the X2Go Client(cross platforms) and a RHEL6 and 7 compatible server (Scientific Linux to be exact)... Please do contact me if you offer any of these services. -- James Pulver CLASSE Computer Group Cornell University

Scientific Linux 6 XFCE issue
by James M. Pulver 28 Jan '16

28 Jan '16

It seems that when we run XFCE or custom desktop xfce4-session, we get the same result over X2Go for XFCE - one panel, that is empty. This is not what we get logging into XFCE on the local console of the computer. Google shows this is often an issue on Ubuntu derivatives, or was several years ago. Has anyone else had this issue on RHEL derivatives? Any idea why it doesn't seem to get the expected panel settings? -- James Pulver CLASSE Computer Group Cornell University

newbie questions and some answers
by Dave Kimble 24 Jan '16

24 Jan '16

It seems that startlxde is part of lxde-common, which is not part of Lubuntu. So if you installed Lubuntu OS you don't have startlxde, whereas if you installed say Ubuntu Server and then added LXDE, you do have startlxde. Anyway I installed lxde-common in Lubuntu, and it all started working. Except the user I get logged in as, doesn't have the settings adjustments I had previously created. This is something to do with /home/username/.config/lxsession/ having both /Lubuntu/ and /LXDE/ folders. It wasn't too time-consuming to set up lxpanel the way I like it, and modify /LXDE/autostart to match /Lubuntu/autostart . I guess I will have to do that 4 times - 2 clients (with screens and keyboards) x 2 servers (headless). I expect this could all be fixed up at the developers' end by adding a LUBUNTU entry to the dropdown list for Session Type, ( and a new set of bindings ?) This needs to be better explained in the blurb too. That just leaves the armhf problem. I have found some hints on building, but I don't know what machine was being used that did it in 1 hour - building wxWidgets took 11 hours for me, and needed a big swapfile too. It would be much better if someone could do it once, centrally, and then maintain an armhf repository. Anyway, x2go works nicely and I'll be sticking with it over x11vnc.

Newbie questions
by Dave Kimble 11 Jan '16

11 Jan '16

I have 4 machines on my LAN, all running Lubuntu 14.04. 2 of them run headless. One of those has armhf architecture - OrangePi PC is a true amazing piece of kit for $15 All are currently running sshd and x11vnc. x11vnc is not a "real" server as it runs under a logged in user account, so the headless machines have to autologin, which I don't like. So I have installed x2goserver v4.0.5.0, x2golxdebindings, and x2goclient on 3 machines successfully, and set up session info for any machine to access any other. But when x2go client tries to connect, it gets through SSH Key negotiation, it brings up a dark grey screen with x2go logo, and then stops "Unable to execute: startlxde". "mlocate startlxde" doesn't find any files. x2goserver status is up and running. I can't find any x2go.log files, but syslog has: x2goclient[12543]: segfault at 0 ip 00000000004b29ee sp 00007ffc1711ac30 error 4 in x2goclient[400000+25a000] I'm at a loss as to what to do next. Is there a repo for x2go on armhf? A diagram of the architecture of x2go modules would be good.

x2go in TCE environment
by ECF Solutions 27 Dec '15

27 Dec '15

Dear all, maybe someone can give me a hint ... I tried to set up a client server solution to replace LTSP. Some Background: 1) Server - 2 CPU -> 8 Core - 20 GB RAM - 1G Network / 2 NIC - Ubuntu 14.04 LTS - VirtualBox 2) Client Futro S400 256 MB RAM or HP Thin Client HSTNC-012-TC (1 GB RAM) I set everything up according to "http://wiki.x2go.org/doku.php/wiki:advanced:tce:install" in an virtualbox (actually 2 boxes - one as "server" one as "pxe-boot-server" - both Ubuntu 14.04 server minimal) 1) "sudo x2gothinclient_update" as well as "sudo x2gothinclient_create" both end with a message that he cannot follow / write to symlink - but seems this is a minor problem 2) when I start a client he gets an IP and boots into the menu - if I choose "Thin Clint..." he further boots into the chroot and finally I get a terminal to log in. Within the chroot I gave root a password and can login. With the command "startx x2goclient" the x2goclient is started and I can establish a session and connect to my application-server. So far so good - but - I can't do this (because of x server errors as "normal user") - minor problem - everything is terrible slow - big problem - LTSP is much much faster ... - I can't change screen resolutions I made the experience that x2go is a wonderful piece of software and when I connect to my company server from outside its nearly as fast as when I work in the office via LTSP... so I assume that I made mistakes ?!? Any hints please? Why is it so unacceptable slow and I thought that I won't get a terminal and the clients would boot direct into the x2goclient window? Best regards - Christian

Ctrl key, and clipboard
by Edward Ned Harvey (x2go) 22 Dec '15

22 Dec '15

I am new to x2go. I just created my first ever x2goserver (centos 6.7 x86_64) and connected my first ever client (OSX). I'm really impressed by the speed, and ability to resize and suspend/resume. But I immediately noticed two problems: My ctrl key doesn't go across. In the remote gnome session, I launch a gnome-terminal, and I start something like ping, and when I press Ctrl-C, the other side just gets a 'c' character. I don't see any way to press Ctrl-C or Ctrl-D and so on. The second problem is the clipboard. Although I have the option selected for bidirectional clipboard, when I copy something on the remote side, it doesn't appear in my local clipboard. I didn't test copying something locally and pasting remotely ... If you want, I can do more testing. The client crashes a lot when you make changes to the session config - but I don't care about that as long as it's reliable during normal usage. Thanks for the development of x2go! Is it ready for production yet? Are these things expected to work yet, or is it something for me to just watch for future usage? Thanks again...

keys not being passed from MacOS client to x2go session?
by Grigory Shamov 21 Dec '15

21 Dec '15

Hi All, This is probably a trivial question: I have installed x2go server, from EPEL, on CentOS 6.6; I'm using Gnome for the desktop. The problem is when I connect using x2go client for older MacOS (i'm on 10.7) some key combinations apparently do not go through. Like, Ctrl+C or Escape or Shift+Ctrl++, all not working. On Windows VM the Windows x2go client works ok. Are there any settings for MacOS x2go clients that can be used to fix it?

Start TCE with an empty login field
by Daniel Berteaud 18 Dec '15

18 Dec '15

Hi. When launching x2go client, it always pre-fill the login field with the content of the $USER variable. If this makes sens most of the time, it doesn't when running in TCE: the login field is always x2gothinclient. I tried to change x2gothinclient_start script, by calling x2goclient like: USER="" /usr/bin/x2goclient --no-menu [... etc...] This works, the login field is empty, but this setting also breaks folder sharing (when calling the x2gomountdirs commands, the login arg is empty, so nothing happens) Is there a way to just start x2goclient with an empty login field ?

TCE, no sound
by Daniel Berteaud 16 Dec '15

16 Dec '15

Hi. I'm setting up a X2go TCE env. It's mostly working, but I still have a few issues. One of those issues is that I have no sound on my thinclients. Here's my setup: - PXE server is running Ubuntu 14.04 amd64. Minimal install, only the thinclient management is installed - Thin client chroot has been setup like explained on the wiki (http://wiki.x2go.org/doku.php/wiki:advanced:tce:install) I kept most of the default settings (so the chroot is a debian Wheezy) - X2go server is a CentOS 7 x86_64 box, with the MATE desktop env Thin clients boot fine and can choose between the CentOS/MATE linux desktop or a direct RDP connection (using the xfreerdp client). But, sound isn't working in either case on the client. I've added the module-native-protocol-tcp loading in the chroot (as explained in the FAQ), on the thin client, I can see that pulse is running and accepting connection on port 4713. Where can I start debuging this ? On the x2go server (the CentOS box), I can see the x2go session command: /bin/bash /usr/bin/x2goruncommand 50 30909 fws-50-1450192269_stDMATE_dp24 30004 mate-session nosnd D Is the nosnd param related ? In my session definition, I've added: sound=true soundsystem=pulse startsoundsystem=true soundtunnel=false Did I miss something ?

Compression/graphics
by Dimitri Loizos 04 Dec '15

04 Dec '15

Is there any way to improve the graphics performance of x2go? Either from the server side or from the client side? Even though the general performance of x2go is fast and fluid, when I open specific applications (e.g. LibreOffice Draw or other graphics related applications), the response becomes so slow that it becomes almost unusable. This is not a problem of the host machine: there is plenty of computing power and memory; also, running VNC I do not experience this issue. I was wondering if there were any settings that I could change either on the server side or client side to fix this problem. I'm running x2go server on CentOS (6.7 and 7), and x2go client on Windows 10. The compression that I'm using is 4k-png. Thank you.

x2go and xinerama
by Dimitri Loizos 04 Dec '15

04 Dec '15

Hello, I have been using x2go for a couple of months now and have been very happy with it. My configuration is a server running a virtual machine (CentOS) on it and x2go server running on that virtual machine. I connect to it through the x2go client on Windows 10. One of the features that I love about x2go is its support for multiple displays on the client side through xinerama. I have 2 monitors and x2go treats the session as such. The session will open across both monitors and I can easily maximize windows on each of these monitors. Well, that was until the latest reboot of the server. Now, even though I have the xinerama option on, the x2go client treats my 2 monitors as one: even though the session opens across both monitors, when I maximize a window, it will be maximized across both monitors. I have tried to reset the client, the server, play with different options, but so far to no avail. Any ideas on how I could get the 2 monitor behavior back? Thank you

When the java applications file chooser dialog wants to access /media then the selection jumps to /tmp but cannot find the hidden folder /tmp/.x2go-{$USER} directory, because it is a hidden .dot directory. Is ist possible to change the hardcoded directories to another, not hidden path, eg. /tmp/x2go-{$USER}... and additionally move the temporary files to the users home directory? Thanks! Klaus

Global ssh-agent
by Dmitry Bely 03 Dec '15

03 Dec '15

Hi, I would like to use ssh-agent globally for X session (Debian/MATE if it matters). X session starts it itself and when I login to X locally it works as expected (SSH_AGENT_PID and SSH_AUTH_SOCK environment variables are set correctly). But if I connect to the host via x2go, strange things happen: in any terminal session SSH_AUTH_SOCK points to non-existing path and SSH_AGENT_PID is not set at all. I tried to work around this adding to ~/.bashrc: if [ ! -S ~/.ssh/ssh_auth_sock ]; then eval `ssh-agent -s` ln -sf "$SSH_AUTH_SOCK" ~/.ssh/ssh_auth_sock fi export SSH_AUTH_SOCK=~/.ssh/ssh_auth_sock This way SSH_AUTH_SOCK is correct but SSH_AGENT_PID is surprisingly unset somethere. Any idea how to fix that? - Dmitry Bely

Hi Stefan! The adding extra spaces before and after "/" are from google translator. I have not seen that after copying / before paste the text, sorry. Thank you for "TC_X2GO_DEBURL = deb http://packages.x2go.org/debian wheezy main" It works now. Bye, Olaf (PS: I am not sure if this posting will be there at the correct place, in the thread. I did not receive any mail after the Authorization-Mail, and I do not see any "reply"-Button on this gmane-page.)

Re: [X2Go-User] Debian Jessie + Openbox / Not working keyboard shortcuts

Hi René, Thank you for your answer. > does ctrl+alt+tab work for you to switch windows? Unfortunately not. [X2Go client is installed on a Windows OS.] [X2Go server is installed on a Debian Jessie OS.] [The session is an OpenBox session.] ctrl+alt+tab allows me to switch from one Windows OS window to another... Thanks for helping.

Debian Jessie + Openbox / Not working keyboard shortcuts
by Lmhelp1 30 Nov '15

30 Nov '15

Hello, I am using Debian Jessie + Openbox. When logged into the machine itself (not via X2Go), I usually hit the keyboard keys Meta + t to start a new XTerm. To be able to do this, I added the following keybind into the OpenBox configuration file "/etc/xdg/openbox/rc.xml": ======================================== <keybind key="W-t"> <action name="Execute"> <command>xterm -fn 10x20</command> </action> </keybind> ======================================== Hitting Meta + t, successufully starts a X terminal. Also, I can hit: Ctrl + Alt + F1 to F6: to switch to the first to the sixth console. Ctrl + Alt + F7 : to switch to desktop mode. These keyboard shortcuts do not work when I am logged into the machine via a X2Go client. Is there something I can do to make these shortcuts work? Thank you and best regards. -- Léa Massiot

Hello I've been using Jessie and Mint on virtual machines and on hardware, but can not seem to get remote print working - due to an sshfs issue. I posted in an earlier email a few days ago. If you have remote print working, could anyone please report back which distro / release works? best regards, Rob Fantini

Putting the below in /etc/sysctl.conf both client and server machine, helped me a whole lot. I was seeing a lot of hesitations and heavy memory *and* swap usage on the server, especially after time idle, as well as overall desktop latency and audio breakup; these knocked it all out. 2G RAM on 1GHz single-CPU old laptop client, 4G on quad-2.6GHz AMD X2 server. net.ipv4.tcp_rfc1337=1 net.ipv4.tcp_window_scaling=1 net.ipv4.tcp_workaround_signed_windows=1 net.ipv4.tcp_sack=1 net.ipv4.tcp_fack=1 net.ipv4.tcp_low_latency=1 net.ipv4.ip_no_pmtu_disc=0 net.ipv4.tcp_mtu_probing=1 net.ipv4.tcp_frto=2 net.ipv4.tcp_frto_response=2 net.ipv4.tcp_congestion_control=illinois vm.swappiness=10 -- *Jonathan E.
