x2gokdrive
by Christoph Pleger 06 Aug '20

06 Aug '20

Hello, I am currently at a loss with the use of x2gokdrive. I am sure that I had it working on an X2Go server some days ago, but now the session ends very quickly, without any Xession being started. And I cannot remember to have changed anything on the server side in the meanwhile. Unfortunately, log files are neither created on the client nor on the server side, and when I enable "Show details" in X2GoClient, nothing more the "Status: connecting" and "Status: Finished" is shown. Regards Christoph

x2go interferes with lyx
by Neal Becker 06 Aug '20

06 Aug '20

$ rpm -q x2goclient x2goclient-4.1.2.2-2.fc32.x86_64 I've noticed that if x2goclient is running that the UI for lyx running locally (NOT remotely) is very sluggish. Trying to operate menus, scroll windows, etc. are very sluggish. Kill x2goclient and the problem stops. lyx is a QT app. -- *Those who don't understand recursion are doomed to repeat it*

Hello, when using x2gobroker, is it possible to disable the possibility to start a session directly on a specific X2Go-Server, so that users are forced to use the broker? Regards Christoph

X2GoBroker with Kdrive
by Christoph Pleger 03 Aug '20

03 Aug '20

Hello, is it possible to use X2GoBroker with Kdrive? In my x2gobroker- sessionprofiles.conf, I have two sections with identical options, with the exception that the first section contains kdrive=false and the second contains kdrive=true. While non-kdrive connections work successfully with the configuration, kdrive connections are aborted. Direct kdrive connections (without broker) to the same destination host work correctly.

X2Go load balancing
by Christoph Pleger 30 Jul '20

30 Jul '20

Hello, I have three questions regarding X2Go load balancing and the X2Go Broker needed for that. The first question is, if it can be avoided that user login data has to be entered twice, once for the broker and once for the X2Go server. Is it possible to configure x2gobroker-daemon so that it forwards the login data it got before to the X2Go server? The second question is if it is somehow possible that with load balancing it is possible that every user can set his or her own connection parameters, like with x2goclient in non-broker mode, with the remote host as only exception. As for example display sizes and internet connection speeds differ between users, it is quite difficult to create so many profiles on the broker machine so that all user wishes are met. The third question is if a kind of load balancing can be achieved that takes into account a) that possibly not all destination hosts have the same hardware power, for example one host may only have 8 CPU cores and 16GB Memory, while another has 64 CPU cores and 256 GB Memory. b) that the real load of a host is not only decided by the number of logged-in users, but also by what the users are doing. Regards Christoph

Massive number of logfile entries
by Craig Morton 30 Jul '20

30 Jul '20

Hi, Newcomer to X2go, set it up on my workstation in the office so I can work remotely. While it's functioning beautifully, I'm noticing a massive number of entries appearing in my system logs, both the secure and messages files. I'm talking several entries per second. Secure is full of constant pam_unix "session closed" and "session open" messages for active X2go connections. Messages is full of system session start information again for active connections. X2go entries in the logs are relatively few and make sense. Why so many entries, and how do I turn them off? Cheers, Craig.

Setting up passwordless session
by funk minion 24 Jul '20

24 Jul '20

Using windows client 4.1.2.0, I'm wanting to set up passwordless authentication. I've followed these instructions.... https://wiki.x2go.org/doku.php/wiki:advanced:authentication:passwordless-ssh ...but am still receiving a small modal dialog box prompting for an account password."Enter user account password:" In the settings for the session, "Use RSA/DSA key for ssh connection:" points to my local private key file and "Try auto login (via SSH Agent or default SSH key)" is checked Question: Is 'auto login' required for passwordless login? Question: Does the term 'default SSH key' reference the id_rsa key created by the ssh-keygen.exe or something else? Question: Does passwordless login require the use of Pageant or other tools, or can it be accomplished solely with x2go settings? thx.

How to scale remote apps on laptop 4k hidpi displays?
by Leho Kraav 16 Jul '20

16 Jul '20

Hi I'm running a 3840x2400 laptop display in 200% scaled mode, on gnome-shell-3.36. x2goclient-4.1.2.2 UI can be fixed up with QT_AUTO_SCREEN_SCALE_FACTOR=1. But remote apps still launch in native resolution, making everything tiny small. This happens for both Wayland and Xorg-based Gnome session. Is there a solution to getting the remote x2go session match the current scale of local display? Mailing list searches for "hidpi" etc failed to find anything useful. -- Leho Kraav, senior technology & digital marketing architect

Connection failed session ... terminated
by Andrew Munn 13 Jul '20

13 Jul '20

I'm running the Windows client v4.1.2.2. Server is CentOS 8. I connect and double-click on the row here: [image: image.png] Then I get this: [image: image.png] This problem happens frequently on all my servers. I can click "New" and open a session but I can never successfully reconnect to that other listed session. I think deleting something from /tmp fixed this in the past. Sound right? Why does this always happen?

Configure x2go-client to not forward specific key combinations?
by Jonah Benton 10 Jul '20

10 Jul '20

Hi folks, I'm interested in using x2go to: * connect into several individual accounts/machines at the same time * use each remote machine desktop in full screen mode * switch between remote full screen desktops using a specific key combination, which would therefore not be sent to the remote Is this possible? In my initial perusal of man pages and testing I don't see a way to do what seems to me to be the (probably wrong) solution- instruct the x2go-client (in either launch remote desktop mode, or desktop screen sharing mode) to not capture a specific key combination (like control-alt-right arrow and control-alt-left arrow) so that the parent desktop can handle them (e.g. switch between parent-side virtual desktops). I'm using Fedora / XFCE for all systems. Thanks very much in advance! Jonah

Client GUI for connecting to broker
by Iain Hallam 09 Jul '20

09 Jul '20

Hi. I'm considering using X2Go broker to implement load balancing for some Linux servers, but many of our users are on Windows devices. Getting them to run the command line options to connect to a broker is going to be tricky; it would be much more useful if we could get them to click on a button, paste in an address, and then they're off and running. Is there any scope for adding a way in the client to connect to a broker from the GUI? Thanks, Iain Hallam.

x2go session failure because of unknown "localhost"
by flegoff 23 Jun '20

23 Jun '20

Hello list, I have been using x2go without issues for a long time until recently. Both client and server are running on Linux machines. I can connect to the server (via an SSH proxy). I get the "New session started" notification. But the session is apparently terminated because tere is some error resoling the display server. I copy pasted the log messages in the enclosed file. I think the important part is this: Loop: WARNING! Overriding auxiliary X11 port with new value '1'. Warning: Overriding auxiliary X11 port with new value '1'. Info: Using abstract X11 socket in kernel namespace for accessing DISPLAY=:0. Error: Failed to resolve address of 'localhost'. Loop: PANIC! Unknown remote host 'localhost'. Error: Unknown remote host 'localhost'. Session: Session terminated at 'Fri Jun 19 22:50:42 2020'. As far as I remember I haven't changed client or server configuration. I did switch from using Published App sessions to Xfce session to I have installed Xfce on the server. Published App sessions do not work either now. Any idea what is going on here? Or how to debug this? Cheers, Fabrice

keyboard config on wayland

Both client and server are Fedora (31 and 32). I'm running a kde/wayland client, with capslock mapped to ctrl. When I connect to the server (running mate) everything works fine, except I don't have capslock mapped to ctrl. Every time I connect (not every time the session starts) I have to run setxkbmap -option caps:ctrl_modifier Oh actually one thing doesn't work. Cut/paste is totally nonfunctional. -- *Those who don't understand recursion are doomed to repeat it*

Problems using HTML5 kvm console
by Simon Beißer 20 Jun '20

20 Jun '20

Hello everyone, we use x2go in our company and it works really well. However, currently we have noticed two problems that occur in connection with an HTML5 KVM (remote console) client. Maybe one of you has an idea about these issues. 1st question When using the keyboard within the KVM console, we noticed that the arrow down key is incorrectly assigned and triggers an Enter. With the help of a keycode event tool I found that the NumpadEnter is transmitted there, see screenshot in the appendix. It seems that the wrong physical key (key code) is transmitted via x2go/nx. This has nothing directly to do with the keyboard layout used and therefore unfortunately cannot be changed within the virtual console. Is this error known? Is there a fix for it? 2nd question OpenGL/GLX is required for the KVM console. Unfortunately, only GLX1.2 is in use among the current nx-libs, which is why this does not work in Firefox. I have found only VirtualGL as workaround. Do you know other methods to make such applications running? Best regards Simon

Minor Enhancement Request
by Matt Rhodes 19 Jun '20

19 Jun '20

Hi, Short version, we'd like the ~/.ssh/config file to be respected for X2GoClient on Windows. Use case: I've been using X2Go heavily with some colleagues on Windows 10. We also use Git quite a bit, which provides SSH via repackaged MSYS. We frequently use the config file at ~/.ssh/config in order to set up all the hosts and connections we use, as there are a lot to manage. We connect a lot to various machines, including local VMs in Hyper-V using both SSH through Git Bash, as well as with X2Go Client. Pain: The current X2Go Client makes us maintain the configurations for each connection separately from the SSH Config file we already maintain. VM images complicate things as the IPs change on us more than we'd like and exacerbate the pain as we have to make IP updates in more than one location. Any useful workaround suggestions until X2Go client can be made to honor the ~/.ssh/config file? Matt.

OT: key modifiers
by Neal Becker 19 Jun '20

19 Jun '20

I have a nasty problem not related to x2go. My desktop is Fedora 32/KDE (pretty sure doesn't matter if wayland or x11). Sometimes I need to edit a MS office document. I've been using vmware horizon to connect to my work, and fire up powerpoint. After using this, (and after closing down horizon), I find all my modifier keys are gone, ALT, CTRL no longer do anything. I don't know how to recover without logoff/logon. As you can imagine, this is not really acceptable. Anyone know how to fix this? Thanks, Neal -- *Those who don't understand recursion are doomed to repeat it*

Re: [X2Go-User] Matlab graphics performance when running in x2go
by Johannes Töger 18 Jun '20

18 Jun '20

I finally figured it out! Now I can run Matlab R2019b on Ubuntu 18.04 LTS with decent graphics performance over x2go, even with transparency using the Mesa llvmpipe software OpenGL driver. Benchmark for a simple scene: No transparency: ~40 ms per frame With transparency: ~58 ms per frmae So still some performance penalty for transparency, but much better. HOWTO: First install LLVM: sudo apt install llvm-dev I downloaded mesa-20.1.0 (latest version right now) and configured it like this (in the unzipped source directory): mkdir build cd build meson -D glx=gallium-xlib -D gallium-drivers=swrast -D platforms=x11 -D dri3=false -D dri-drivers="" -D vulkan-drivers="" -D buildtype=release -D optimization=3 -Dprefix=/usr/local/mesa-20.1.0/ Then I built and installed it as follows: ninja sudo ninja install Then to make Matlab load the new driver, I needed to modify Matlab's lib search path: cp $MATLAB_DIRECTORY/bin/.matlab7rc.sh ~ Edit the file ~/.matlab7rc.sh, find the glnxa* section and add /usr/local/mesa-20.1.0/lib/x86_64-linux-gnu to LDPATH_PREFIX Add to your .profile: export MESA_GL_VERSION_OVERRIDE=3.0 Seems like anything will work for the version override except for 3.1, but I didn't debug this further. — Johannes Töger Associate Senior Lecturer Cardiac MR Group Department of Clinical Sciences Lund, Clinical Physiology Lund University, Sweden -----Original Message----- From: Ulrich Sibiller <uli42(a)gmx.de> Sent: Wednesday, May 27, 2020 14:29 To: Johannes Töger <johannes.toger(a)med.lu.se> Subject: Re: [X2Go-User] Matlab graphics performance when running in x2go Thanks!

Suspending sessions causes performance slowing down
by h i 17 Jun '20

17 Jun '20

Hello, We've been using x2go for a few months. Recent converts from using the old freenx nomachine 3.5. We installed x2goserver on Ubuntu mate 18.04 and have several users connecting through x2goclient 4.1.2.2 I have a question regarding suspended sessions with x2go. When we suspended an open session, we noticed the session stopped running. After resuming the session the next day, the process resumed executing. Thought this was strange and rebooted the server. Ran a few tests and noticed performance slows after suspending a session. Here is output from gxlgears. You can see the FPS decreases when the session suspends. The FPS returns back to normal (633 at the bottom), upon resuming the session. [cid:d252b9bd-2ad8-4a2a-800c-7e6c2a417eef] I searched online and discovered you can change the /etc/x2go/x2goagent.options to X2GO_NXOPTIONS="sleep=0". When doing this, now the performance increases considerably after suspending the session (middle portion of the output). [cid:4ba36847-76fc-4d46-ad13-1f0165a293c2] Is there a way to suspend an x2go session, and have no decrease or increase in performance? Is there some setting we can change to keep things running as is while session is suspended? Thanks in advance. h

Blender 2.83 crashes
by Shoe Off Head 08 Jun '20

08 Jun '20

Hi, I have a legitimate need to use Blender (not a render farm) remotely for short/light work. I tested X2Go but only Blender 2.79 in the softwaregl mode did run (uses llvm-pipe for OpenGL software rendering). Blender 2.79 in normal mode and Blender 2.83 did crash in normal and softwareql mode. I wonder is real OpenGL (not software OpenGL like llvm-pipe) a No-Go for X2Go? Thanks for your help! P.S.: here is the Blender crash message: # backtrace ./blender(BLI_system_backtrace+0x1d) [0x6989e9d] ./blender() [0xc1548f] /lib/x86_64-linux-gnu/libc.so.6(+0x3ef20) [0x7f601308ef20] ./blender(_Z33GHOST_X11_ApplicationErrorHandlerP9_XDisplayP11XErrorEvent+0x11) [0x17304f1] /usr/lib/x86_64-linux-gnu/libX11.so.6(_XError+0x11a) [0x7f60142d18fa] /usr/lib/x86_64-linux-gnu/libX11.so.6(+0x3d82b) [0x7f60142ce82b] /usr/lib/x86_64-linux-gnu/libX11.so.6(+0x3d8d5) [0x7f60142ce8d5] /usr/lib/x86_64-linux-gnu/libX11.so.6(_XReply+0x240) [0x7f60142cf830] /usr/lib/x86_64-linux-gnu/libXi.so.6(XListInputDevices+0x84) [0x7f6014086d44] ./blender(_ZN15GHOST_SystemX1120refreshXInputDevicesEv+0x5f) [0x1731a3f] ./blender(_ZN15GHOST_SystemX11C1Ev+0x453) [0x1732193] ./blender(_ZN13GHOST_ISystem12createSystemEv+0x35) [0x172eda5] ./blender(GHOST_CreateSystem+0x9) [0x172dc29] ./blender(wm_ghost_init+0x2d) [0xee800d] ./blender(WM_init+0x275) [0xed4135] ./blender(main+0x2a3) [0xb4bf53] /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xe7) [0x7f6013071b97] ./blender() [0xc11c0c]

Where are x2go compression options explained?
by Anton Driesse 29 May '20

29 May '20

X2Go offers a long list of compression options, obviously with some system behind them. Can anyone tell me where can I find explanations for these? Many thanks! Anton

how to select single display
by gian sisal 27 May '20

27 May '20

Hi everyone, I already asked about this topic, but no answers until now. So I'm going to ask again: I need to connect to a multi-monitor remote system (CentOS on it), I'm using a windows x2go client: no problems about connection: I'm able to connect to such remote system, but I need to select a single display I want to view on my screen. The actual 4.1.2.0 client version doesn't allow me to do this. Is there any update about this situation? Thanks in advance. Greetings. G

Matlab graphics performance when running in x2go
by Johannes Töger 27 May '20

27 May '20

Hi everyone, We're running x2go on a compute server. Some of our apps are written in Matlab with interactive GUI:s. We are seeing quite poor graphics performance after moving from Matlab R2014a to R2019a, especially when using transparency in 3D graphics. This might be connected to the fact that Matlab goes into a software OpenGL mode. Does anyone have experience with this? Any solutions? Ubuntu 18.04 LTS MATE desktop environment Matlab R2019a x2goserver 4.1.0.3-0~1708~ubuntu1 libnx-x11-6:amd64 2:3.5.99.22-0+git20190 nxagent 2:3.5.99.22-0+git20190 - Johannes Töger Associate Senior Lecturer Cardiac MR Group Department of Clinical Sciences Lund, Clinical Physiology Lund University, Sweden

Server/Client Timeout
by brian 26 May '20

26 May '20

I'm using x2go to log into a server that I have woken from a suspended state using a wake-on-lan command. It appears that the server pc is not aware of the x2go connection, and returns to a suspended state shortly after I connect with the x2go client. About 10 minutes. Are there keep-alive settings or time-out parameters, or other means that can be configured is x2go to prevent this from happening? Thanks, brian, ny

x2goversion problem affecting pyhoca-cli, and a solution
by Michael Ashley 26 May '20

26 May '20

Hi folks, While trying to get pyhoca-cli to work, I noticed that x2goversion on the server was printing out the version numbers without the leading component names. E.g., : 4.1.0.3 : 4.1.0.3 : 4.1.0.3 : 4.1.0.3 : 4.1.0.3 : 3.5.99.23 : 4.1.0.3 instead of: x2goserver: 4.1.0.3 x2goserver-common: 4.1.0.3 x2goserver-extensions: 4.1.0.3 x2goserver-fmbindings: 4.1.0.3 x2goserver-printing: 4.1.0.3 x2goserver-x2goagent: 3.5.99.23 x2goserver-xsession: 4.1.0.3 The problem was that my X2GO_VERSIONS_BASEPATH had a ".." in it, which caused the following line in x2goversion to fail: X2GO_COMPONENT="$(echo "${compfile}" | cut -d '.' -f '2')" A fix is to replace the line with: X2GO_COMPONENT=${compfile#*VERSION.} Finally, to have a working pyhoca-cli, you need to use the version from 11 March 2020 or later https://code.x2go.org/gitweb?p=pyhoca-cli.git;a=tree Regards, Michael

x2gokdrive: disable menu bar
by Martin Lange 21 May '20

21 May '20

Hello, I am experimenting with x2gokdrive right now. It works great, much faster than nx in a local network. I have only one problem: Is there an option to disable the kdrive menu bar overlay in an active session? I didn't found anything in the wiki. This menu is useful on fat clients, but on thinclients (with x2gothinclient and x2gobroker) it is unnecessary and would confuse my users. Thanks in advance! Martin

SSH compression
by Simon Reiter 17 May '20

17 May '20

Hi, I already read a few information about the compression used in x2go at https://github.com/ArcticaProject/nx-libs/issues/802. My naive assumption would be that using the compression in x2go makes any compression in the SSH config obsolete, because the compression is only a general one and the one in x2go should suite better for what to be transmitted. Since x2go reads my SSH config, I am now wondering, if the “Compression” option in the config file is ignored when establishing the connection or not. On my current setup, the x2go server requires a ProxyJump, which I set up in the x2go session settings. Does it provide better performance to do it like this or rather open manually a SSH connection to the target host with some local forwarding? And also here with or without compression? I am very happy for some recommendations. Best regards, Simon Reiter

x2go occasionally stops responding
by Andrew Munn 12 May '20

12 May '20

I can connect to my x2go session running XFCE on CentOS 8.1. The x2go client runs on Windows. Screen updates are still pushed to my client correctly (on-screen clock shows correct time), however sometimes my kb and mouse actions start being ignored. I can disconnect and reconnect to the same session from another windows PC and the results are the same. So something on the CentOS server appears to be the issue, The only way I know to recover is kill the x2go session on the server and reconnect.

Semi-Offtopic: The sorry state of Landline and Mobile Internet in Germany
by Stefan Baur 11 May '20

11 May '20

Hi List, in an adjacent thread, Alex made a statement that low-bandwidth internet connections are a thing of the past, and thus NX is basically obsolete. I have personal experience to share which proves him wrong. The following internet speeds were recorded in a suburb of a metropolitan area with more than 185 000 residents. And yes, I have the screenshots to prove it, I just don't want to burden the list with them. Residential DSL: Downstream: 5.435 MBit/s max, 5.233 MBit/s average Upstream: 0.465 MBit/s max, 0.427 MBit/s average Ping latency: 23.00 ms min, 28.94 ms average Residential Cable: Downstream: 35.14 MBit/s max, 28.06 MBit/s average Upstream: 2625 MBit/s max, 2.426 MBit/s average Ping latency: 32.00 ms min, 39,38 ms average (iow, higher throughput than DSL, but higher latency) -> This will, however, get worse, as Cable is a shared medium and people in the area are getting fed up with their DSL speeds and are switching over to Cable as their contracts expire. LTE, 1st of 2 providers: 3 out of 5 bars Downstream: 4.715 MBit/s max, 2.029 MBit/s average Upstream: 3.923 MBit/s max, 3.706 MBit/s average Ping latency: 48.00 ms min, 60.50 ms average LTE, 2nd of 2 providers: 2 out of 5 bars Downstream: 0.325 MBit/s max, 0.214 MBit/s average Upstream: 0.325 MBit/s max, 0.225 MBit/s average Ping latency: 64.00 ms min, 79.25 ms average Now step outside and move another 800 meters towards the city limits, and LTE provider 1 drops to UMTS/EDGE (and GSM on a bad day), while LTE provider 2 actually goes up to 3-4 bars and gets 3-7 MBit/s peak rates - but they are short peaks/bursts in an otherwise very mediocre reception. Nothing you want to rely on. Again, this isn't Mooville, West Virgina, with 100 inhabitants and 75 of them cattle, but a larger city in the self-proclaimed high-tech nation Germany. Even Finnish rural areas have better UMTS and LTE coverage than we in Germany have, at the outskirts of our cities. And no, I'm not making this up, I've been to such areas in Finland in the last two years, and I know what the reception there was like. So NX will be here for quite some time, there is a need for it, and for less fancy, but lightweight desktops that work well with it. -Stefan -- BAUR-ITCS UG (haftungsbeschränkt) Geschäftsführer: Stefan Baur Eichenäckerweg 10, 89081 Ulm | Registergericht Ulm, HRB 724364 Fon/Fax 0731 40 34 66-36/-35 | USt-IdNr.: DE268653243

The procedure was simple, but is of course not 100% reproducible because the mouse movements can be different each time. But the import condition is that the window is only **moved** by clicking on the top bar and dragging it somewhat to the right and a bit down. After the move, keep the mouse down and keep it there for two or three seconds. Three remote desktops: (standard) Ubuntu, Gnome Classic, MATE. The remote session size is 800x600. The local desktop is 1440x900. To start I have only grepped the lines with "nxagentChangeScreenConfig:" In the case of MATE the bug does not show up, but in the other two cases it does. ===============MATE====================

new x2go client for windows
by Paul Borowicz 08 May '20

08 May '20

I've been using the 4.1.2.0 windows client with no issues aside from the clipboard occasionally getting messed up. I usually restart the client and it fixes the problem. I just tried the 4.1.2.2 client, hoping it fixed this. It works fine when I access my OpenSuse server, but when I try to access my Red Hat 7 server it drops with no error output. I tried using the debug console and it also crashes. I can't seem to find a way to output the debug info somewhere I can capture it. Can you point me at the files necessary for to submit a bug report? I see this on the server: Session: Resuming session at 'Wed May 6 08:56:15 2020'.

The future of x2gokdrive
by Oleksandr Shneyder 07 May '20

07 May '20

Hello guys, this is for those of you how is wondering in which direction development of x2gokdrive is going. As you may know, I mostly working now on the development of x2go kdrive, which will be used parallel to NX. The client part of x2go kdrive is quite simple and not depends on Xorg, which makes possible to create the clients for mobile and web platforms. I made some proof of concept and quickly developed a simple HTML5 client which is connecting to x2gokdrive over websockets. I used websockify to connect ws to tcp socket. The client has limited support for mouse and keyboard events, no support for cursors, but it's enough to create the image how it'll work. I attached the screenshot of plasma5 session running in browser tab with libreoffice and youtube video running in browser. regards, Alex -- ----------------------------------------------------------- Oleksandr Shneyder | Email: o.shneyder(a)phoca-gmbh.de phoca GmbH | Tel. : 0911 - 14870374 0 Schleiermacherstr. 2 | Fax. : 0911 - 14870374 9 D-90491 Nürnberg | Mobil: 0163 - 49 64 461 Geschäftsführung: Dipl.-Inf.

Resizing bug
by Kees Bakker 07 May '20

07 May '20

Hi, The client shows a weird resizing bug. I want to know what I can do to analyse this further and report it as a bug. I've mentioned this already earlier on the [X2Go-User] mailing list [1]. I'm surprised that I'm the only one seeing this, because I see it on all the environments that I work on. That is, on all PCs where I am logged in with the standard Ubuntu desktop. My client is Ubuntu (with Ubuntu desktop) and the server side is Ubuntu with a Mate (or Openbox or XFCE) session. Also worthwhile to mention that I don't have my x2go client full screen. When I move(!) the X2GO window, it resizes(!). And when I keep the mouse clicked on the top bar for the move, (and even if I don't move anymore) it keeps resizing until it reaches the maximum height of my local monitor. BTW. That maximum monitor height is not(!) the maximum height of my local window manager. The maximum height for the X2GO client window is the monitor height minus the height of the top bar. What I also noticed is that the height increments in steps of 37 pixels. I'm not sure, but I think the the height of the top bar in the Ubuntu desktop is 37. Here are the last few lines of the remote session.log. I start with a session of 800x600 Info: Screen [0] resized to geometry [799x600] fullscreen [0]. Info: Screen [0] resized to geometry [799x674] fullscreen [0]. Info: Screen [0] resized to geometry [798x674] fullscreen [0]. Info: Screen [0] resized to geometry [798x711] fullscreen [0].

Stefan: Well you are correct in that it doesn't seem to be needed. I disabled it as a start-up application and it makes no difference on my ability to log in to the remote machine. Thinking about it now, I'm not sure of it's intended use; if I'm logging into an unattended remote machine and starting a new session, then desktop sharing is not required. If I'm logging in to a remote machine to share a desktop with someone local to it at the other end, they can always start the desktop sharing service manually. Either way it's not an issue. Never the less, thank you for your informative responses. brian > Message: 3 > Date: Mon, 4 May 2020 19:17:15 +0200 > From: Stefan Baur <X2Go-ML-1(a)baur-itcs.de> > To: x2go-user(a)lists.x2go.org > Subject: Re: [X2Go-User] multiple instances of x2go server appearing > in tray > Message-ID: <78d6d9c8-83c6-adba-c4cf-45197237add2(a)baur-itcs.de> > Content-Type: text/plain; charset=utf-8 > > Am 04.05.20 um 19:03 schrieb b salzano: > > Stephan: Abject apologies - I misstated the issue.

Stephan: Abject apologies - I misstated the issue. The tray icon is indeed for x2go desktopsharing, and that is exactly the function that I need to use. So the question I meant to ask, then, is whether there is a config file somewhere that will prevent more than one instance of desktopsharing to run in a particular account. Xfce (what I normally use) doesn't provide any options to manage that aspect. Perhaps someone knows what config file to look at?

In fact, X2GoServer doesn't display any icons in your tray (X2GoClient does that on the client side, obviously). What you're seeing there looks like the applet belonging to the X2Go package <https://packages.debian.org/buster/x2godesktopsharing>, from what I can tell. If you don't need that particular feature, it should be safe to simply uninstall that package. If you do want to use it, you need to find out why the applet is being started multiple times. -Stefan -- BAUR-ITCS UG (haftungsbeschränkt) Geschäftsführer: Stefan Baur Eichenäckerweg 10, 89081 Ulm | Registergericht Ulm, HRB 724364 Fon/Fax 0731 40 34 66-36/-35 | USt-IdNr.: DE268653243

How to start a specific program from the client command line?
by Chris Green 03 May '20

03 May '20

I have been using x2go for a while now to run a couple of desktop programs on my laptop, I also use it to run the whole of the desktop's xfce session sometimes. It's excellent, thank you all. I currently have an icon in my panel which runs the following:- x2goclient --session=<session name> This brings up the x2go client GUI with the appropriate session loaded and asks for my password. Being a command line junkie I'd quite like to bypass the GUI if I can, so is there any way to get x2go[client] to ask for the password on the command line and go on to run the session? Alternatively can I get x2go to use ssh's ControlMaster setting as I nearly always have an ssh session running to my desktop so further ssh connections don't ask for my password again. -- Chris Green

The only strange thing I'm encountering is that my tray will display up to 8 or 9 instances of x2goserver running at any one time. Only one will show OK (green check mark), the others will show with a red 'x' instead. The number of x-ed out server instances vary. Might be one. Might be 8. Entirely random. See attached photo. I can close each x-ed out entry indivdually and x2goserver still works just fine after that. In fact it shows no problems at all; works perfectly. I'm running on linux, Debian, Buster 10. A hardinfo report on the OS, kernel, and environment is also attached. Is there any config file I can go to to eliminate this one little quirk? Thanks for the help. brian

Question about the change in proxy/nx3.py
by Pavel 30 Apr '20

30 Apr '20

Hi, I am using my own small python application which is based on X2GoClient class from python-x2go. The application runs on windows, so it is necessary to start nxproxy.exe. The binary sits in C:\Users\user\win_apps\nxproxy\nxproxy.exe and in my app I set the environment variable NXPROXY_BINARY pointing to this path. This whole thing worked very well with python-x2go==0.5.0.6. Now I am on my way from Python2 to Python3, so I noticed, the newer version of python-x2go is also trying to be Python3 compatible. I made the necessary changes in my app and updated python-x2go to 0.6.1.3. But my application stopped to work. The reason was, nxproxy.exe didn't start. I tried to find out the problem and noticed there is an error log file in C:\users\user\.x2go\S-user-50-1588199962_stRxterm_dp32 containing: Loop: PANIC! Can't open options file '.\..\S-user-50-1588199962_stRxterm_dp32\options'. Error is 2 'No such file or directory'. Error: Can't open options file '.\..\S-user-50-1588199962_stRxterm_dp32\options'. Error is 2 'No such file or directory'. So I looked further and noticed this change in nx3.py between 0.6.0.2 and 0.6.1.0: - self.PROXY_OPTIONS= [ 'nx/nx', 'options=%s' % os.path.join("\\", "..", "S-%s" % self.session_info.name, 'options'), ] + self.PROXY_OPTIONS= [ 'nx/nx', 'options=%s' % os.path.join(".", "..", "S-%s" % self.session_info.name, 'options'), ] I reverted this change and my app worked correctly again. Now my question is: what is the motivation to change the path to options file and eventually, if the change is correct, what should I do in my app to be able to start nxproxy.exe again? The path to options file look as relative path, but to what? To nxproxy binary, or to nxproxy directory, or to session_id directory? The explanation would be very welcome. Thanks in advance. Pavel
