Me too, the docs seem to mention vnc (which is a bit slower), but can it work on x2go?

Accelerated graphics on headless server
by Arjun Krishnan 15 Jun '18

15 Jun '18

Hi I'm sure this question has been asked many many times before, but I was hoping one of you could quickly point me in the right direction. I have a headless server, and I'm trying to write a file /etc/X11/xorg.conf.d/xxx.conf, but this doesn't seem to be having any effect. Example 20-dummy.conf <https://www.dropbox.com/s/p0jqump05s0s9r6/forx2go-20-dummy.conf?dl=0> or 20-intel.conf <https://www.dropbox.com/s/eqvw4gmtxgn1lh9/forx2go-20-intel.conf?dl=0> I'd like hardware acceleration, the xrandr command, and kodi to work remotely. Currently I get errors that look like this: $ xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 320 x 240, current 1916 x 1029, maximum 1920 x 1200 default connected 1916x1029+0+0 0mm x 0mm 1280x800 60.00 320x240 60.00 640x360 60.00 640x480 60.00 800x480 60.00 800x600 60.00 1024x600 60.00 1024x768 60.00 1152x864 60.00 1280x720 60.00 1280x1024 60.00 1360x768 60.00 1440x900 60.00 1600x900 60.00 1600x1200 60.00 1680x1050 60.00 1920x1080 60.00 1920x1200 60.00 1916x1029 60.00* So it seems that x2go does not care about my xorg.conf files at all. Any suggestions? Arjun

stale dated gnupg key
by o1bigtenor 12 Jun '18

12 Jun '18

Greetings I had successfully installed, and have been using x2go for some time (useful software when one has a number of computers to run!). Wanted to install x2goserver on another machine and was running into a number of issues. I believe I have been able to unravel the problem enough to find at least one of the roots of not being able to install even when following the steps published in the wiki. My install was failing when I tried to install the apt-key and by lots of poking and some sideways thinking I have found the issue. Looking in the system where x2go is working happily in /etc/apt/trusted/gpg I find that the key is liked with the following information: pub rsa2048 2011-03-10 [SC] 972F D88F A0BA FB57 8D04 76DF E1F9 5838 5BFE 2B6E uid [ unknown] X2go Debian/Ubuntu Packaging <debian(a)x2go.org> sub rsa2048 2011-03-10 [E] what is interesting is that of the 12 keys listed (likely not that many compared to possibilities) the x2go key is only rsa2048 which might be sufficient but its also listed as 2011-03-10 [E] which I interpret to mean that the key was generated on the date 2011-03-10 but I'm thinking the [E] means that its expired. As renewing the key is not something that I can do as a user I am requesting that someone with the capabilities of modifying the code might please renew and/or refresh the gnupg key and also inform users of the new key (I am assuming that the key would change with renewal/update). Given the rights to do so I would be more than happy to modify the wiki to reflect that new apt-key code. Thanking in advance those doing this - - - (please advise if (including the how) the wiki is to be updated by myself) Dee

installation woes
by o1bigtenor 11 Jun '18

Greetings I was able to setup x2go server on a couple machines about 8 months or so ago and have found the 'system' to be a very valuable tool (it cuts down on the need for more monitors and other peripherals). Just recently I have be working on installing x2go on a different system than previously and I am running into some problems. I have been following : https://wiki.x2go.org/doku.php/doc:installation:x2goserver and https://wiki.x2go.org/doku.php/wiki:repositories:debian The first issue that I am having is that I am unable to add the repository keys. After typing in the command (checked and rechecked a number of times for accuracy) I keep getting the following as a response: $ gpg: keyserver receive failed: No data I have tried using search engines to find some method of resolving this difficulty but I cannot find anything that would fit this circumstance. Please, how do I affect the installation of the site key? Regards Dee

Couple of notes here, I installed x2go server on Zorin. Zorin is yet another Ubuntu derivative with a hopelessly broken Gnome and KDE implementation. I am using Mate or LXDE both of which do work. The Nightly Build connects then immediately disconnects. The Stable works mostly okay. I am having problems with the stable leaving sessions up and not deleting them when I logout. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Forcing connection speed setting based upon IP address
by Steve Bergman 29 May '18

29 May '18

Hi, I have a central LAN, where the X2Go server and many clients live, and several branch offices which connect via the WAN. I used to be able to modify the FreeNX 'nxacl' script to force 'LAN' for local clients, and 'ADSL' for everyone else. Last I looked, there was no such facility in the X2Go server, and the team had posted good reasons (which I can't quite recall) why that file was not coming back. But does X2Go server have a way for me to accomplish what I want? I still find the occasional misconfigured client. Thanks, Steve Bergman

Large latency when opening a new session
by Laurent Pouilloux 29 May '18

29 May '18

Dear X2go-users, for almost 2 years we are using X2GO with VirtualGL to provides visualization tool on our computing facility and it is very efficient tool. However, we are facing a problem with our current setup that seems related to the number of users connected. We have a machine built on a Dell R730 server (40 cores, 512 GB, Quadro P2000) installed on Centos 7. X2go is installed from EPEL repository, in version 4.0.1.22 For about one month, establishing the connection is very slow. As you can see in the log file below, it waits two minutes before to start a first session (lpouillo-1103-1526465870_stDXFCE_dp24) that does not seem to work then create a second one about 10 minutes later(C-lpouillo-1159-1527588238_stDXFCE_dp24) This error seems correlated with the number of active users, including pts (when it is > 80) but I don't see any limits (max pty, max open files, or in x2goserver.conf which is the one by default) that is reached. Do you have any idea on how to diagnose/solve the problem ? Tell me if you need more information. Best regards, Laurent Pouilloux Ex : May 29 11:54:14 visu systemd-logind: New session 17176 of user lpouillo. May 29 11:54:14 visu systemd: Started Session 17176 of user lpouillo.

(Auto) grab keyboard using Windows client and Linux server

23 May '18

I am looking for an option to enable/disable or on mouse click have the X2go windows client grab the keyboard so that all further keystrokes including Alt - Tab combinations would be responded by the remote server. Noticed an issue ((Auto) grab keyboard · Issue #384 · ArcticaProject/nx-libs) logged for this issue that seems to have the fixes committed in Aug 2017. Unable to find any configuration to enable this in the latest X2go client (v 4.1.1.1) downloaded from download:start [X2Go - everywhere@home] Any ideas? Any one got this working?

So, it's a known issue, that eventually will be solved. Thank you for the clarification.

Trouble terminating a kde session
by Joao Roscoe 17 May '18

17 May '18

I Have a fresh, up-to-date install of debian 9 x86-64, including x2go from the repos (the package version is 4.1.0.0-0x2go1). So far kde5 is working pretty well. Sure, not as fast as XFCE, but quite usable. With kde5, however, I'm running into an issue at logout: right after clicking the logout button, the display into the session window goes black, and a few seconds later, it shows a dialog stating that ksmserver segfaulted. Clicking "Close" results a briefly displayed second, similar dialog stating the same about drkonqi, and then, after closing that, yes, the session terminates. Using the "Shutdown" button results in exactly the same behaviour. The client is running on up-to-date debian 8 x86 (32 bits). The client package version is 4.0.3.1-4. Has anyone noticed this issue before? Any hints? Best regards, Joao

Problems with java GUI application
by Kevin Kremer 17 May '18

17 May '18

Hi all, I set up an X2Go server to connect to a remote machine and most applications run very well. Unfortunately I rely on one java application where some of its GUI components suffers huge latencies. Here, actions like a click on a button take up to 10 seconds to perform while there is no delay when running the application without X2Go. The latencies can be reduced to 4 seconds by reducing the connection speed to "MODEM" and the image quality to 0. However, the latency is still huge compared to running the application locally. Furthermore, the java application does not re-print its window and it stays blank when minimizing the X2Go window. My setup: I use Xfce as a desktop, the connection speed is set to "MODEM", the compression algorithm is set to 16m-jpeg, the image quality is set to 0 and I use Oracle's JRE 1.8.0_152. The problems also occur when I connect to the host within the same LAN. Maybe someone has encountered similar problem and can give me a few hints for solving them. Best regards, Kevin

installing x2go server on a mostly headless RHEL 7, solving black screen on Windows client
by Heinz Wrobel 08 May '18

08 May '18

Hi, I found a few interesting things when trying to install the x2go server on a somewhat customized and mostly headless RHEL 7 VM in the cloud, specifically in this case on a RHEL 7.2. These findings might help others, so I thought I'd post the details with some side notes. Following the instructions on https://wiki.x2go.org/doku.php/doc:installation:x2goserver for RHEL 7 was not quite enough to install a working server on this specific RHEL 7 VM. Due to the various documented issues with Gnome 3, I had switched the VM to "Server with GUI" with Xfce, but it still didn't help. On installing Xfce I even had to skip a broken dependency regarding sound support to make it install, but that is a side note only in case you also see something like that. I don't care about sound, so that single thing was easy to ignore for me. In any case, when trying to connect with a Windows x2go client, not even the X desktop window on the client showed up initially. Some investigation and log searching revealed that /usr/bin/x2goruncommand relies on dbus-run-session. This RHEL 7 machine only had dbus-launch because its dbus libs are older, and therefore it completely failed to even invoke the Xsession properly. So I hacked x2goruncommand to do the following fallback: ---- typeset dbus_wrapper="$(type -P "dbus-run-session")" typeset dbus_wrapper_args="" if [ -z "${dbus_wrapper}" ]; then typeset dbus_wrapper="$(type -P "dbus-launch")" typeset dbus_wrapper_args="--exit-with-session" fi [...] XSESSION_EXEC="$cmd" STARTUP="/usr/bin/env LD_LIBRARY_PATH=${LD_LIBRARY_PATH} ${STARTUP}" ${dbus_wrapper} ${dbus_wrapper_args} /etc/x2go/Xsession >> "$MESSAGE_FILE" 2>&1 ---- This little hack was good enough to make the client show the server window, but I got a black window only. No remote desktop in sight still. Using htop on the server, I saw that while the x2goagent was running, there was no xfce4 session of any kind or anything else that looked like a process related to any desktop session. After a long set of weird and clueless debug steps I found a problem because I manually invoked "dbus-launch --exit-with-session /etc/x2go/Xsession". It complained about elements in bash-completion.d not being valid identifiers, starting with "_itweb-settings()". Anything bad that can be fixed should be fixed while debugging along, so I started fixing those to see what might happen next. Iteratively I went through the following files in /etc/bash_completion.d to remove the "-" from the function name identifiers only(!) that it was complaining about: - rhn-migrate-classic-to-rhsm - rhsm-debug - rhsm-icon After the manual invocation of the Xsession no longer complained about bash-completion, I tried the client and ... Ta Da! ... the session came up and seems to work well now. I am sure there are other things that may need fixing and your mileage may vary, but all that is for another day. The moral of the story: It's not always just older dbus libs or similar things. Even seemingly unrelated bash completion quirks can make the x2go Xsession script fail to start up ... and not show anything in any obvious log file. BR, Heinz

Desktop sharing: "No shared desktop found"
by Jens Bürger 05 May '18

05 May '18

Dear all, I tried to set up desktop sharing as described here: https://wiki.x2go.org/doku.php/doc:usage:desktop-sharing all locally in the same LAN segment, so forwarding of port 22 shouldn’t be an issue. On a session, I start x2godesktopsharing and active sharing of the session. On another client I try to connect to the server as described but I only get a message „No shared desktop found“. What should I check? Kind regards, Jens

X2go session won't connect
by Paul Borowicz 03 May '18

03 May '18

I've been wrestling with a strange error that only seemed to be affecting my Linux laptop (OpenSUSE Tumbleweed), connecting to my Linux server (OpenSUSE LEAP). Sessions seemed to start, but wouldn't connect. If I tried to connect a 2nd time, it appeared to offer me an existing session, but would not connect. The client scrolled errors related to "unknown remote host 'localhost', and "unable to resolve remote host 'localhost'. Turned out I had removed the localhost entry from my /etc/hosts file. ------------ /etc/hosts 127.0.0.1 localhost --------- Adding this back, fixed this problem. I'm sending this email in case it is helpful to others. I couldn't seem to find any documentation mentioning localhost. Paul Borowicz

X2Go TCE classic fails / use TCE-Live instead?
by Jens Bürger 02 May '18

02 May '18

Dear people of X2Go, I did a fresh install of Debian 9 in a VM. I installed X2Go as stated here: https://wiki.x2go.org/doku.php/doc:installation:x2goserver Then I tried to install the thin client environment as explained here: https://wiki.x2go.org/doku.php/wiki:advanced:tce:install I did not manage to get it running. First, I tried x2gothinclient_create with mainly the default options. The process aborted, in between 404s came up because the x2go-repos apparently don’t have wheezy support anymore. Then I switched to stretch and tried again. This seemed to work out, but the following links in /srv/tftp are broken (i.e. the files are missing) pxelinux.0 -> /usr/lib/syslinux/pxelinux.0 vesamenu.c32 -> /usr/lib/syslinux/vesamenu.c32 memtest86+.bin -> /opt/x2gothinclient/chroot/boot/memtest86+.bin In a third try, I changed the release to jessie and started x2gothinclient_create over. The process then aborts with unmet dependencies of x2goclient-chroot… I meanwhile noticed the existence of TCE Live, but stating "This page is very much Work in Progess. Please leave a note on x2go-user(a)lists.x2go.org if you're interested in trying this out, so we can guide you along if something goes wrong.“ So, here I am :) My first question is: what is the recommended method for thin client environment? What do I need to consider if I want to use the Live method? Kind regards, Jens

Best Linux Distro for x2go server sessions as of April 2018?
by John Stoffel 14 Apr '18

14 Apr '18

Guys, So what's the best linux distro to run x2go on these days, in terms of the server, the system you connect to? Which would people recommend? RHEL 7.x is out, as are probably a bunch of the newer Gnome 3 desktops. Does anything running MATE work well? Running Debian 9.3 with lxde seems to work pretty well, using client 4.1.1.1 to connect. But at my $WORK, where we're mostly RHEL/CentOS based, it looks like sticking with CentOS 6.9 is the best solution currently. Which kinda stinks. Does Fedora work better or at least just as well when running the Mate desktop? John

Problem with X2Go 4.0.1.22-2 on Centos 7.3
by Roger Moye 13 Apr '18

13 Apr '18

We are having trouble getting our X2Go client on Windows to connect to our Linux server. The Linux server is running Centos 7.3 and these RPMs: [root@hre-rsgpul01 admin-rmoye]# rpm -qa |grep -i x2go x2goserver-xsession-4.0.1.22-2.el7.x86_64 x2goagent-3.5.0.33-4.el7.x86_64 x2goserver-4.0.1.22-2.el7.x86_64 The X2Go client is 4.1.1.1 on Windows. When we login to the server, the X2Go window appears as if the Linux desktop is about to appear and then the session is terminated. The only thing I see that is noteworthy in /var/log/messages on the server is: /usr/bin/x2goruncommand: dbus wrapper not available This error does NOT appear on servers where we are able to connect successfully. However, those servers are running an older version of X2Go server. I have not been able to find any explanation for what this error means or how to avoid it. We have tried running different window managers like XFCE and GNOME and all produce the same result. Can anyone shed any light on this?

Folks: I've switched my desktop and server to Freebsd. And am looking for an x2go like experience. I see that the x2go client is in ports/pkgs but the x2go server is not. Seems like an incomplete match if you ask me. This setup will allow me to control my work machines from home, but not allow me to control my home machines from work. vnc tunneled over vpn/ssh is rather slow and awkward in some cases. Suggestions welcome.

X2Go crashes when I run Thunderbird
by Tristan Miller 05 Apr '18

05 Apr '18

Dear all, Lately whenever I try to run Thunderbird through X2Go, the session suddenly closes. The session doesn't get suspended, since when I reconnect I need to create a new session rather than resuming the old one. I assume that the server is crashing or otherwise failing, since the client remains open. Any idea what the problem is or how I can go about diagnosing this? I'm running x2goclient 4.1.0.0 on openSUSE Leap 42.3 and x2goserver 4.0.1.20 on openSUSE Tumbleweed.

X2Go Client suddenly failing to connect
by Ivan Gomez 29 Mar '18

29 Mar '18

Dear all, I have been using X2Go client in the current environment for quite a while now without issues. Seemingly all of sudden today an outage happened where X2Go will no longer launch any applications. The connection seems to succeed in the backend: [cid:image001.png@01D3C558.EB0F51C0] However, the client closes the connection before anything happens. Running the client with the debug terminal shows these messages: [cid:image002.png@01D3C559.58693F10] I've validated that I can SSH to the server using other tools and start the X11 applications from command line directly. Any guidance or pointers to figure out why X2Go stopped working would be greatly appreciated. Thank you, Ivan G.

line editing not enabled, Connection Failed (Xiki)
by Karl A. Woelfer 27 Mar '18

27 Mar '18

We have a user who is unable to launch X2go, receiving the following errors: Conection Failed ~/Xiki/bin/.xsh line (...) bind : warning : line editing not enabled Is this maybe a known conflict between key mappings ? I am not very familiar with the Xiki shell. Are there any workarounds people can offer? Thanks for your collective expertise, - Karl

x2go stops working on some Ubuntu 14.04 boxes
by Qianqian Fang 26 Mar '18

26 Mar '18

Dear list, I run a small cluster for my lab, including about 12 Linux boxes running Ubuntu 14.04 (1x with 16.04). We have been using x2go and ssh as the primary tool to access these computing resources. Recently (started a month ago), I noticed there were package updates of x2go server (now 4.1.0.0-0-1517), client (now 4.1.1.1-0-1719) and the nx11 libraries, on the other hand, I started having difficulty log on to some of my servers, and this list starts to grow. I am not sure if this was the result of the recent package upgrade, or the reason motivated the package updates, but I started seeing the below two types of messages: For some of the machines, I saw the below message initially: *The remote proxy closed the connection while negotiating* ** *the session. This may be due to the wrong authentication* ** *credentials passed to the server.* for some other servers, I am getting the below message: *Connection failed.**Failed to start X2Go Agent session with ID account-xxxxxx_stDXFCE_dp24. X2Go Agent terminated unexpectedly. Aborting session startup. * The 1st message appeared first, after I tried to restart x2goserver or rebooting the machine, or apply the updates, deleting the ~/.x2go folder, or a reboot, those machines typically display the 2nd message; none of those were fixed using the above procedures. right now, I have about 2/3 of the my servers are not accessible via x2go. I would like to know if there is a workaround. thanks Qianqian

x2go - Problems (flicker) with fullscreen on Windows 10 after x2go server update
by Johannes Kind 26 Mar '18

26 Mar '18

Hi, I'm running x2goserver on Xubuntu 14.04. After updating x2go server via "apt-get --dist-upgrade" we have problems using x2go-client on MS Windows. We usually start the session in window-mode and by double-click on the head bar the window goes to fullscreen. After last upgrade fullscreen does not work anymore, the window flickers and is not really usable. Could anyone help? Which additional information do you need? I wanted to revert installation, but in cache there is just the current version: (f8-automation) johannesk@mgn-wx-rd-sit:~/dev/f8-automation$ apt-cache showpkg x2goserver Package: x2goserver Versions: 4.1.0.0-0~1517~ubuntu14.04.1 (/var/lib/apt/lists/ppa.launchpad.net_x2go_stable_ubuntu_dists_trusty_main_binary-amd64_Packages) (/var/lib/dpkg/status) Description Language: File: /var/lib/apt/lists/ppa.launchpad.net_x2go_stable_ubuntu_dists_trusty_main_binary-amd64_Packages MD5: e785564ddcdc9f9013b7175366b891a0 Description Language: en File: /var/lib/apt/lists/ppa.launchpad.net_x2go_stable_ubuntu_dists_trusty_main_i18n_Translation-en MD5: e785564ddcdc9f9013b7175366b891a0 Reverse Depends: x2goserver-common:i386,x2goserver 4.1.0.0-0~ x2goserver-common:i386,x2goserver 4.1.0.0-0~ libx2go-server-db-perl:i386,x2goserver 4.1.0.0-0~ libx2go-server-db-perl:i386,x2goserver 4.1.0.0-0~ x2goserver:i386,x2goserver x2goserver-x2goagent,x2goserver 4.0.1.20~ x2goserver-x2goagent,x2goserver 4.0.1.20~ x2goserver-x2goagent,x2goserver x2gomatebindings,x2goserver 4.0.1.4-0~ x2gobroker-agent,x2goserver 4.0.1.16-0~ x2goserver-common,x2goserver 4.1.0.0-0~ x2goserver-common,x2goserver 4.1.0.0-0~ libx2go-server-db-perl,x2goserver 4.1.0.0-0~ libx2go-server-db-perl,x2goserver 4.1.0.0-0~ x2goserver-fmbindings,x2goserver 4.1.0.0-0~1517~ubuntu14.04.1.1~ x2goserver-fmbindings,x2goserver 4.1.0.0-0~1517~ubuntu14.04.1 x2goserver-pyhoca,x2goserver 4.0.1.22-0~1197~ubuntu14.04.1.1~ x2goserver-pyhoca,x2goserver 4.0.1.22-0~1197~ubuntu14.04.1 x2goserver-xsession,x2goserver 4.1.0.0-0~1517~ubuntu14.04.1.1~ x2goserver-xsession,x2goserver 4.1.0.0-0~1517~ubuntu14.04.1 x2goserver-printing,x2goserver 4.1.0.0-0~1517~ubuntu14.04.1.1~ x2goserver-printing,x2goserver 4.1.0.0-0~1517~ubuntu14.04.1 x2golxdebindings,x2goserver 3.0.99.6-0~ x2goserver-compat,x2goserver 4.0.1.22-0~1197~ubuntu14.04.1.1~ x2goserver-compat,x2goserver 4.0.1.22-0~1197~ubuntu14.04.1 plasma-widget-x2go,x2goserver 3.1.1.2-0~ x2goserver-extensions,x2goserver 4.1.0.0-0~1517~ubuntu14.04.1.1~ x2goserver-extensions,x2goserver 4.1.0.0-0~1517~ubuntu14.04.1 x2godesktopsharing,x2goserver 4.0.0.0-0~ x2goagent,x2goserver x2goagent,x2goserver 4.0.1.21-0~ x2goagent,x2goserver 4.0.1.21-0~ x2goagent,x2goserver Dependencies: 4.1.0.0-0~1517~ubuntu14.04.1 - x2goserver-common (2 4.1.0.0-0~1517~ubuntu14.04.1) x2goserver-common (3 4.1.0.0-0~1517~ubuntu14.04.1.1~) debconf (18 0.5) debconf-2.0 (0 (null)) init-system-helpers (2 1.13~) libfile-basedir-perl (0 (null)) libfile-which-perl (0 (null)) libtry-tiny-perl (0 (null)) libswitch-perl (0 (null)) libx2go-server-perl (2 4.1.0.0-0~1517~ubuntu14.04.1) libx2go-server-perl (3 4.1.0.0-0~1517~ubuntu14.04.1.1~) x2goserver-x2goagent (2 4.1.0.0-0~1517~ubuntu14.04.1) x2goserver-x2goagent (3 4.1.0.0-0~1517~ubuntu14.04.1.1~) bash (0 (null)) lsof (0 (null)) bc (0 (null)) openssh-client (0 (null)) openssh-server (0 (null)) pwgen (0 (null)) xauth (0 (null)) psmisc (0 (null)) net-tools (0 (null)) xfonts-base (0 (null)) xkb-data (0 (null)) rdesktop (0 (null)) pulseaudio-utils (0 (null)) sshfs (0 (null)) x11-apps (0 (null)) x11-session-utils (0 (null)) x11-utils (0 (null)) x11-xfs-utils (0 (null)) x11-xkb-utils (0 (null)) x11-xserver-utils (0 (null)) fontconfig (0 (null)) xinit (0 (null)) x2goserver-extensions (2 4.1.0.0-0~1517~ubuntu14.04.1) x2goserver-extensions (3 4.1.0.0-0~1517~ubuntu14.04.1.1~) x2goserver-xsession (2 4.1.0.0-0~1517~ubuntu14.04.1) x2goserver-xsession (3 4.1.0.0-0~1517~ubuntu14.04.1.1~) x2goserver-fmbindings (2 4.1.0.0-0~1517~ubuntu14.04.1) x2goserver-fmbindings (3 4.1.0.0-0~1517~ubuntu14.04.1.1~) x2goserver-printing (2 4.1.0.0-0~1517~ubuntu14.04.1) x2goserver-printing (3 4.1.0.0-0~1517~ubuntu14.04.1.1~) x2godesktopsharing (3 3.1.1.2-0~) x2godesktopsharing:i386 (3 3.1.1.2-0~) x2goserver-compat (0 (null)) x2goserver-compat:i386 (0 (null)) x2goserver-home (0 (null)) x2goserver-home:i386 (0 (null)) x2goserver-one (0 (null)) x2goserver-one:i386 (0 (null)) x2goserver-pyhoca (0 (null)) x2goserver-pyhoca:i386 (0 (null)) x2goserver-compat (0 (null)) x2goserver-compat:i386 (0 (null)) x2goserver-home (0 (null)) x2goserver-home:i386 (0 (null)) x2goserver-one (0 (null)) x2goserver-one:i386 (0 (null)) x2goserver-pyhoca (0 (null)) x2goserver-pyhoca:i386 (0 (null)) x2goserver:i386 (0 (null)) Provides: 4.1.0.0-0~1517~ubuntu14.04.1 - Reverse Provides: Thanks in advance and best regards, Johannes Kind ADVA SE Märzenquelle 1-3 98617 Meiningen Germany +49 3693 450 325

timeout connecting to new server
by Michael Stauffer 24 Mar '18

24 Mar '18

CentOS 7.4 Hi, I've installed x2go using yum on a new server (yum --enablerepo="epel" install x2goserver, and yum --enablerepo="epel" install x2goserver-xsession) and rebooted it. I also installed MATE and Xfce packages. However when I try to connect with x2go client (4.1.1.1 on windows 10), I get a timeout. Connecting to our old x2go server works. I've disabled the firewall for testing but it still times out. I can successfully ssh using x-forwarding to the new x2go server. /var/log/messages doesn't show anything useful. Any thoughts about what might be happening? Thanks -M

Mouse clicks delayed
by Michael Eager 23 Mar '18

23 Mar '18

I'm running Thunderbird on a remote server. Whenever I click on a dropdown menu, it takes about 30 seconds for the application to respond. I can't tell if the delay is in sending the mouse event or in displaying the menu. This does not happen when clicking on buttons (like Print or Reply), but only when there is a dropdown, like ReplyAll or the settings dropdown, or in the menus in a composition window. I don't notice this delay with other applications. There is no delay when I run Thunderbird remotely using "ssh -X". The server is running CentOS 7, kernel-4.15, x2goagent-3.5.0 x2goserver-4.0.1 The client is running Fedora 27, kernel-4.15, x2goclient-4.1.1. -- Michael Eager eager(a)eagerm.com 1960 Park Blvd., Palo Alto, CA 94306

Best client/server pairings for RHEL 6 server and linux/windows clients?
by John Stoffel 20 Mar '18

20 Mar '18

Guys, I'm using x2go server on a CentOS 6.9 box, kept quite upto date, and I have no problems connecting to it from both the desktop of that system, and from home when I'm connecting in from a Linux desktop. My versions are: Server (Linux CentOS 6.9): x2goclient-4.0.1.4-1.el6.x86_64 x2goserver-4.0.1.20-1.el6.x86_64 x2golxdebindings-debuginfo-1.0.2.4-1.1.x86_64 x2goserver-xsession-4.0.1.20-1.el6.x86_64 python-x2go-0.5.0.3-1.el6.noarch x2goagent-3.5.0.32-3.1.x86_64 Linux Client (Linux Mint 18.3): ii nxproxy 2:3.5.0.33-0x2go1+git20180204.776+8.main.1 amd64 NX proxy ii x2go-keyring 2012.07.23~jessie~main~17~build1 all GnuPG keys of all X2Go developers and the X2Go archive ii x2goclient 4.1.1.1-0x2go1+git20180302.1732+8.main.1 amd64 X2Go Client application (Qt4) But when I try to use the latest client stuff from my Windows 7 system, I just get a connection which shows up for a second, then disconnects and returns me to the connection screen. I can't figure out what I'm doing wrong. But I'm loathe to upgrade my server just in case I break a working setup. In the meantime I've built a new CentOS-7.4 system, which is using the same packages as my CentOS 6.9 server, but for some reason I just can't reliably connect there either. Been following the mailing list for a while, since this is really my best option to be able to have my linux sessions travel around with me. But debugging has been a chore, since there are so many files and places which need to be looked into. And it's not clear WHY connections fail. And actually, does RHEL/CentOS 7 with a Gnome desktop even work? Is there an issue with OpenGL like there is with VNC desktops? Thanks, John

x2go problems - Ubuntu 16.04 - before and after new version upgrade
by Steven Spencer 19 Mar '18

19 Mar '18

Greetings, I sent this yesterday, but was not a member of the list, so wasn't sure if it would end up being approved and posted or not. Here's the content of that message and I apologize if this is a duplicate: We use x2go extensively for some access to some Ubuntu based LTSP servers. Suddenly over the last two days, we get the following in the client: "The remote proxy closed the connection while negotiating the session. This may be due to the wrong authentication credentials passed to the server." And on the server we are trying to connect to, we see this in the logs: /usr/bin/x2goresume-session: client [ip.address.of.client] has successfully resumed session with ID kscadmin-51-1520534328_stDMATE_dp24 /usr/bin/x2gosetkeyboard: /home/ksca0dmin/.x2go/C-kscadmin-51-1520534328_stDMATE_dp24/keyboard did not appear within 30s after agent startup We are never able to connect. This happens even on all servers that we connect to and includes older server versions: x2goagent: 3.5.0.33 x2goserver: 4.0.1.22 x2goserver-extensions: 4.0.1.22 x2goserver-xsession: 4.0.1.22 As well as newer ones: x2goserver: 4.1.0.0 x2goserver-common: 4.1.0.0 x2goserver-extensions: 4.1.0.0 x2goserver-fmbindings: 4.1.0.0 x2goserver-printing: 4.1.0.0 x2goserver-x2goagent: 3.5.99.14 x2goserver-xsession: 4.1.0.0 Unfortunately, the clients are now updated as well trying to fix this issue, but they were failing on the older client version as well: X2Go Client v. 4.1.1.1 (Qt - 4.8.7) Any help would be appreciated.

open another customizing Port Forward thought the SSH Connection to the x2go Server
by Feustel, Thomas 19 Mar '18

19 Mar '18

Hi, Is it possible to open an induvial port forward from the client machine to the x2go server? I need this for a windows software to connect to the Linux server. My first approach wars to use on the client a ssh_config, but the client creates the connection directly from the x2go client application with some ssh libs. So ok, the next approach wars to use the ssh_config on the Linux site, because for the printer and the file connection, the server open a ssh connection to a ssh-Daemon on the Client site. But the ssh connection use the option "ClearAllForwardings", so the forwards on a config-file are not working. So someone have an idea for this topic? Greetings

Some questions about X2go
by Torsten Kupke 19 Mar '18

19 Mar '18

Hi all, on my working PC there is running Ubuntu 16.04 with MATE Desktop (isn't the same as Ubuntu MATE, right?) and a X2go Server with Desktop Sharing extension. On my home PC with Windows 10 I have installed the X2go Client and inside it configured a session connecting to the Ubuntu host according to https://wiki.x2go.org/doku.php/doc:usage:desktop-sharing. The connection is successful, but there are some issues: 1. The Ubuntu host's desktop is spread over two 4/3 screens. But The Windows PC only has one screen with 1680x1050 Pixels. So the display from the Ubuntu host is highly horizontally compressed, so that the texts are nearly unreadable. OK, this behaviour is documented, but is there a way to get it more readable? 2. If I (to solve the above issue) switch to something other than full screen mode in the session settings, the session crashes, when started. I have to close and restart the X2go Client. And then with settings set back to full screen mode the session runs again. Is there a way to avoid the crash without full screen mode? 3. In full screen mode I cannot see any mouse cursor. So hitting any user elements inside or on the windows inside the display from the Ubuntu host is very difficult, since they are reduced to half the width. Is there a way to see a mouse cursor? Or is this due to the compressed display? 4. Since mouse using is so difficult, I tried to close the windows from the Ubuntu host by pressing <Alt><F4>. But then I get a question from X2go to close the session. Is there a way to propagate key combinitions like <Alt><F4> to the remote host? Sincerely tkansgar

Deprecation and removal of X2Go Plugin
by Mihai Moldovan 19 Mar '18

19 Mar '18

Hi Since most browsers either stopped supporting NPAPI (or will be dropping support with the next ESR version) and Qt 5 does not feature a browser plugin architecture any longer, I will be ripping out code related to the X2Go Plugin in the development version of X2Go Client soonish. Expect the next version to not supply X2Go Plugin binaries. Mihai

Problems with X2go keyboard layout
by Thomas Stephan 15 Mar '18

15 Mar '18

Dear X2golist, we are using X2go to connect to our Ubuntu workstations from various clients. Since some days we had problems to get connected, now after updating client and server we can connect again. After connecting to the server we see the window with the desktop, and are able to start programs as usual. However, the keyboard seems to deliver random results, e.g. the keys 1,2,3,4,5,6 map to e,r,t,z,<enter> in a terminal on the remote-server. Here is our setup: Client is MAC OSX 10.11, running x2goclient 4.1.1.1 for MAC OS X 10.10 Server: Ubuntu 16.04.4 LTS (Xenial Xerus) output from x2goversion on the server is cups-x2go: 3.0.1.3 x2godesktopsharing: 3.1.1.4 x2goserver: 4.1.0.0 x2goserver-common: 4.1.0.0 x2goserver-extensions: 4.1.0.0 x2goserver-fmbindings: 4.1.0.0 x2goserver-printing: 4.1.0.0 x2goserver-x2goagent: 3.5.99.15 x2goserver-xsession: 4.1.0.0 Any ideas?
