Bug#1464: x2goclient 4.1.2.2 version does not work with Pageant SSH authentication agent
by saion.chatterjee＠siemens.com 04 Aug '20

04 Aug '20

Package: x2goclient Version: 4.1.2.2 With the latest x2goclient version available as of today ( x2goclient 4.1.2.2-2020.02.13 ), user faces authentication error while trying to login using Pageant SSH agent. The error message received is: "Access denied for 'publickey'. Authentication that can continue: publickey Access denied for 'none'. Authentication that can continue: publickey" The error does not happen with the previous version of x2goclient. Tried and tested with x2goclient 4.1.2.0 and it works fine. Pageant version used is: Pageant Release 0.73 The client's OS: 64-bit x86 Windows 10 The server's OS: Ubuntu 19.04 best regards, Saion

KDrive does not seem to honor compression settings in X2GoClient?
by Stefan Baur 27 Jul '20

27 Jul '20

Hi List, hi Alex, Same environment as for the ten previous issues/oddities ... This time, I tried out "Connect to Windows Terminal Server". In NX mode, I can set the compression to "nopack", and it does have an effect. But it looks like choosing "nopack" when KDrive is selected has no effect. With "16m-jpeg" in NX mode, but not with "nopack", I am getting nasty JPEG artifacts when moving a window around. In KDrive, these artifacts are always there, no matter what I select. I have attached two screenshots, one with the contrast enhanced so the issue is easier to spot. Is this intentional? If so, "compression" should be greyed out in KDrive mode. But, on the other hand, those artifacts are annoying, so we need to make them go away somehow. Should I file a bug?

Ten X2Go-KDrive bugs/oddities
by Stefan Baur 27 Jul '20

27 Jul '20

Hi List, hHi Alex, Lately I was able to test a few more things with X2Go-KDrive, and I encountered some bugs/oddities with it. Maybe you could comment below which issues I should file as a bug, and what further info (like, screenshots, package versions, content of certain config files, ...) I should try to gather before filing it, to make debugging/fixing it easier? All tests were performed with an Ubuntu 18.04 LTS Client; and X2GoClient from the stable repository. The host ran on Debian 10.4, and was using the X2Go heuler repository, with the following X2Go-related packages: ii libx2go-log-perl 4.1.0.4-0x2go1.2~git20200228.1815+10.heuler.1 all Perl X2Go::Log package ii libx2go-server-db-perl 4.1.0.4-0x2go1.2~git20200228.1815+10.heuler.1 amd64 Perl X2Go::Server:DB package ii libx2go-server-perl 4.1.0.4-0x2go1.2~git20200228.1815+10.heuler.1 all Perl X2Go::Server package ii x2go-keyring 2019.08.21~git20190824.119+11.heuler.1 all GnuPG keys of all X2Go developers and the X2Go archive ii x2goserver 4.1.0.4-0x2go1.2~git20200228.1815+10.heuler.1 amd64 X2Go server ii x2goserver-common 4.1.0.4-0x2go1.2~git20200228.1815+10.heuler.1 amd64 X2Go Server (common files) ii x2goserver-extensions 4.1.0.4-0x2go1.2~git20200228.1815+10.heuler.1 all X2Go Server (extension support) ii x2goserver-fmbindings 4.1.0.4-0x2go1.2~git20200228.1815+10.heuler.1 all X2Go Server (file manager bindings) ii x2goserver-printing 4.1.0.4-0x2go1.2~git20200228.1815+10.heuler.1 all X2Go server (printing support) ii x2goserver-x2goagent 4.1.0.4-0x2go1.2~git20200228.1815+10.heuler.1 amd64 X2Go Server's X2Go Agent Xserver ii x2goserver-x2gokdrive 4.1.0.4-0x2go1.2~git20200228.1815+10.heuler.1 amd64 X2Go Server's X2Go KDrive Xserver ii x2goserver-xsession 4.1.0.4-0x2go1.2~git20200228.1815+10.heuler.1 all X2Go Server (Xsession runner) ii xserver-x2gokdrive 0.0.0.1-0x2go1~git20200120.183+10.heuler.1 amd64 KDrive graphical server backend for X2Go Server ii libnx-x11-6:amd64 2:3.5.99.22-0~git20190928.3526+10.heuler.1 amd64 nxagent's libNX_X11 client-part library ii nx-x11-common 2:3.5.99.22-0~git20190928.3526+10.heuler.1 all nx-X11 (common files) ii nxagent 2:3.5.99.22-0~git20190928.3526+10.heuler.1 amd64 Nested Xserver (aka NX Agent) supporting the NX compression protocol First issue/oddity: No matter which Desktop Environment is being used on the remote end, the local client window seems to snap to the top left position in an 800x600 resolution (or maybe even smaller, like 640x480), then it resizes to the requested size. This can be seen during resume, where the resume happens on the 800x600 (or whatever) resolution, then the screen is resized, and you see "garbage" on the screen (cloned sections of the client window content), until it redraws the entire screen after resizing it properly. This takes about a second or so. This may also be the reason why in one particular situation (during another test, on a different setup) I saw the KDrive window getting stuck at that small size in the upper left corner - probably the "maximize" command didn't reach the window manager, or there was no window manager present, or something like that. Second issue/oddity: Only roughly every second attempt to resize the client-side KDrive window using the mouse works. The other attempts have it snap back to where it originally was, once you let go of the mouse button. Third issue: At least in most of the desktop environments tested, both keyboard autodetection AND keyboard manual selection fails, so you're stuck with a US keyboard inside the session. The notable exception is GNOME, here, keyboard settings work, even in autodetection mode! Fourth ... well, oddity: In Fullscreen sessions, the top-of-the-screen Config Bar's Minimize Button does not work unless fullscreen mode has been toggled off and on again. Fifth issue: The modes "Published Application" and "XDMCP" are selectable with KDrive, but do not do anything useful; "Single Application" is only useful together with KDrive when the application in question has a fullscreen mode (like "rdesktop -f") Sixth issue: The top-of-the-screen Config Bar has a button "Disconnect". This should be named "Suspend" (or "Disconnect and suspend"), to be more in line with current X2Go terminology, and to make it more clear to the user that this isn't terminating the session, but rather suspending it. Also, Ctrl-Alt-T should suspend the session just like in classic NX mode, but currently does nothing. Seventh issue: LXQt complains on session startup that "global keyboard shortcut Ctrl-Alt-D for Desktop could not be registered" (Popup message) Eight issue: In Fullscreen mode (but not in windowed mode!), when using LXQt, MATE, XFCE or KDE, clicking the "Disconnect" button in the top-of-the-screen Config Bar does suspend the session, but any attempts at reconnecting lead to a client-side abort. The only way to recover is to either start X2GoClient with --no-autoresume, and terminating the session from the session chooser, or to log in via ssh and issue a x2goterminate-session command with the corresponding session ID. Ninth issue: KDE complains on session startup that I should enter Admin credentials for configuring a system update proxy? Tenth issue: GNOME complains on session startup that I should enter Admin credentials to update system repositories. (This popup appears even twice.)

Bug#1225: x2goclient / pyhoca does not honor ProxyJump in .ssh/config
by Filip Krikava 27 Jul '20

27 Jul '20

Package: x2goclient; Version: 4.1.0.0 Due to the configuration of the university network, I have to first connect to a frontend, then to a node and then to a VM. To make this easy to use, I set ProxyJump in my .ssh/config. This works really well for ssh. However, it does not seem to be recognized by x2go. I have to manually tunnel the ssh port from the VM on my localhost to be able to connect there via x2go. The same is for pyhoca-cli 0.5.0.3.

Bug#1489: Windows x2go client ignores ProxyJump
by Carsten Bockelmann 27 Jul '20

27 Jul '20

Package: x2goclient Version: 4.1.2.2-2020.02.13 Similiar to this old bug https://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=1225 ProxyJump is ignored under windows 10. However, the underlying libssh 0.9.3 now supports ProxyJump and at least in ubuntu 20.04 it works out of the box. This is especially frustrating as host certificates are not supported in libssh which currently blocks any config in x2goclient that directly configures the bastion host as proxy (kex exchange method unsupported).

extend x2gopath
by Ulrich Sibiller 10 Jul '20

10 Jul '20

Hi, I would like to fix the long-standing bug that x2gostartageni sets NX_CLIENT to x2gosuspend-agent, which is simply wrong. I would like to point it to nxdialog, if available. The best way to find out the correnct nxdialog path is probably using x2gopath. But I am not really sure how all that x2gopath stuff is supposed to work. I mean, depending on the distribution, nxdialog might be on different locations. E.g. the nx-libs Makefile(s) install nxdialog to $BINDIR, which is $PREFIX/bin by default. The packager can redefine BINDIR and/or PREFIX. x2gopath does not know about BINDIR, it only knows PREFIX. So how can I determine the BINDIR used during packaging of nxdialog? Can anyone shine a light on this? Uli PS: nx-libs.spec does not build an nxdialog rpm yet, so that's needs to be fixed, too.

x2goClient code refactoring
by Dave Chamberlin-Kidd 07 Jul '20

07 Jul '20

Hi, Whilst digging through the code in the x2goClient I've come across void ONMainWindow::processSessionConfig() in onmainwindow.cpp but I can't see anywhere where this code is called. Commenting it out along with a stack of associated code doesn't seem to have any affect. So my question is, is there something obvious I'm missing? If not I'll root through the code and find any other associated bits, rip them out and submit a patch. Cheers Dave

Bug#1479: Possible typo in two x2gothinclient scripts
by Stefan Baur 25 Jun '20

25 Jun '20

package: x2gothinclient-common version: 1.5.0.2-0x2go2~git20200109.735+10.heuler.1 x2gothinclient/management/share/etc/x2gothinclient_init.d/010_x2gothinclient-fresh-home and x2gothinclient/management/share/etc/x2gothinclient_init.d/005_x2gothinclient-wipe-home contain a check if the variable X2GO_HANDLE_DAEMON is not empty. However, this variable is never filled, it seems. There is a variable X2GO_HANDLE_DAEMONS (note the extra S at the end) that gets set to "false" in some scripts. My guess is that these two scripts contain a typo and lack the S.

x2go doesnt work from Qubes OS
by bo0od 22 Jun '20

I wonder why x2go doesnt connect using Qubes OS? i have tested x2go from debian it works ok , but when using it from Qubes OS it doesnt connect with message saying "connection refused" though ssh works fine from the same machine on Qubes OS. So is there extra needed package to be installed? or its just unsupported? *Tested on Debian Buster Template ThX!

Bug#1477: x2goclient doesn't prompt for password after authentication failure if server is using google-authenticator
by Toby 18 Jun '20

18 Jun '20

Package: x2goclient Version: 4.1.2.2 I have installed Google Authenticator on my x2go server, and use keyboard-interactive for ssh passwords. If I mistype my password in x2goclient, it won't offer me another password prompt, but repeatedly asks for the Verification code until sshd on the server gets bored and closes the connection. Expected behaviour: if the login is not successful, prompt for both password and verification code again. x2goserver: Scientific Linux 7.7 - 3.10.0-1062.12.1.el7.x86_64 x2goclient: Fedora 32 - 5.6.14-300.fc32.x86_64 Cheers Toby

Fwd: [ArcticaProject/nx-libs] Document compression (#802)

And it means exactly what it says: do not compress images. This setting saves CPU cycles but required more bandwidth. Images are normally cached this so this is relevant only for the tiem an image must be transferred to the other side. All the things I documented are valid for plain NX sessions (without using x2go but other software). In NX - if you don't specify a compression method explicitly but only a link type - the compression method is derived from the link type. For ADSL you correctly expect adaptive-7 as I listed in the document. Using x2go things are a bit different. The NX code is the same and so are the built-in defaults. For ADSL this is still "adaptive-7". But x2go does always provide a compression type in addition to the link type. So that default is never used but overridden by the compression settings the user specifies in x2go's session configuration. So regarding compression you always get what you select there, in your case it is "nopack" (which becomes "none" at some point because of the internal naming of the parameter). In other words: in x2go you always have to select a clever combination of link speed and compression while using plain NX you can stick with the link speed and use the defaults. If you only touch the link speed setting you will always get 16m-jpeg. I am using an own software for connection (which I cannot make public for legal reasons) and always stick with the defaults. I was not aware of this x2go behaviour. But this might explain why I don't see the performance problems I sometimes hear about from other people. So I consider this a bug. Developers: what's your opinion about this?

X2Go Kdrive, current status? Ready for official release?
by Mike Gabriel 27 May '20

27 May '20

Hi Alex, I wonder when would be a good point to get X2Go Kdrive to the majority of X2Go users. I will plan some X2Go work for July and this would be a good occasion to get a new X2Go Server version out containing the X2Go Kdrive wrapper code. What's the maturity status of X2Go Kdrive? Is it releasable? If not, we should get an X2Go server release out anyway and make sure it behaves well, if no X2Go Kdrive Xserver ist installed server-side. What do people think about this?

Q: What kind of content do you plan to add to the X2Go wiki? A: I'm not sure yet. I'm interested in looking at the x2go client and will hopefully be able to submit some patches to help out. As I get to know the code and wiki I'm sure I'll find some info I can add to improve the docs.

x2goClient GUI code refactoring
by Dave Chamberlin-Kidd 24 May '20

24 May '20

Hi, I'd like to have a go at bug fixing, tidying up and adding features to the x2goClient and to start with I have spent a bit of time looking at the sessionbutton code to try to get to know it a bit. Having done so I think it would be useful to submit some refactoring patches. Once I've done this, I would then like to take the same approach with some of the other classes (onmainwindow being the next obvious candidate) This is the sort of thing that I can imagine isn't high priority for the core devs but it will, I think, make future improvements much easier to code, review and test. I don't want to stand on any toes so thought I would ask the following before submitting anything... 1: Is the above proposal acceptable? 2: If so is there a particular approach you would like me to take? (my plan is to start by extracting code into smaller functions in a series of small commits) 3: Do the dev team have any other thoughts/suggestions as to things they would like to see as part of a refactoring that I might be able to pick up Just to be clear, to start with my intention is to make the code easier to understand and follow without changing any functionality. Cheers Dave

Bug#1474: keyboard and mouse stop working after a few minutes of inactivity
by K. Kirsa 24 May '20

24 May '20

Package: x2goserver Version: 4.1.0.3-5 Ubuntu server 20.04 lts with xubuntu-desktop, installed on actual hardware, not a vm. No physical keyboard or mouse connected. After a while of inactivitiy (neither keyboard nor mouse are being used for a few minutes), the keyboard and mouse controls are lost. The session itself does not freeze: Windows with constantly updating contents or panel plugins still work. Resizing the x2go client window correctly resizes the remote xfce desktop. It's just like the keyboard and mouse are being disconnected somehow. It does not matter, if the x2go client (ms windows) stays connected or if I disnonnect and reconnect the client after a few minutes to resume the session: Keyboard and mouse even get lost during my "absence". The problem seems to be independent of the client. A new session suffers the same fate after a few minutes of inactivity. I disabled the screensaver and session locking in xfce settings. There's nothing I'm aware of happening in xfce that could act as a trigger for the keyborad and mouse loss. I searched the logs but did not manage to find any errors. Any ideas on where to look or what to try next? BTW: The same machine works perfectly fine with 18.04 lts, xubuntu-desktop and x2goserver.

Confusing Debian/Ubuntu versions
by Kees Bakker 22 May '20

22 May '20

Hey, The latest Ubuntu (focal) package has version 2:3.5.99.23-1build1. The first few lines in debian/changelog are: nx-libs (2:3.5.99.23-1build1) focal; urgency=medium * No-change rebuild for libgcc-s1 package name change. -- Matthias Klose <doko(a)ubuntu.com> Mon, 23 Mar 2020 07:21:04 +0100 nx-libs (2:3.5.99.23-1) unstable; urgency=medium * New upstream release. * debian/control: + Bump Standards-Version: to 4.5.0. No changes needed. * debian/nxagent.install: + Drop nxagent.xpm from pixmaps/ folder. Not shipped upstream anymore. * debian/rules: + Some extra quotes. Reduce delta between upstream DEB packaging and official Debian package. * debian/copyright: + Update copyright attributions. -- Mike Gabriel <sunweaver(a)debian.org> Thu, 30 Jan 2020 12:01:07 +0100 But debian/changelog in arctica/nx-libs (in the branch that was used for the release contains: nx-libs (2:3.5.99.23-0) unstable; urgency=medium * Upstream-provided Debian package for nx-libs. See upstream ChangeLog for recent changes. -- Mike Gabriel <mike.gabriel(a)das-netzwerkteam.de> Thu, 30 Jan 2020 10:59:43 +0100 nx-libs (2:3.5.99.22-0) unstable; urgency=medium * Upstream-provided Debian package for nx-libs. See upstream ChangeLog for recent changes. -- Mike Gabriel <mike.gabriel(a)das-netzwerkteam.de> Tue, 27 Aug 2019 15:44:17 +0200 This is confusing. 2:3.5.99.23-0 is the latest from arctica, but Ubuntu focal already has 2:3.5.99.23-1. Mike, what's going on? -- Kees

Bug#1473: Cinnamon icon is loaded as a cog not the official Cinnamon logo
by Dave Chamberlin-Kidd 20 May '20

20 May '20

Package: x2goclient Version: 4.1.2.3 Severity: wishlist Tag: patch When the original code to load the Cinnamon icon was implemented it appears there wasn't an official icon. There is now. There is no error message as the code works as is but an incorrect icon is used for Cinnamon. This patch replaces the cog icon and removes the comment explaining why it was used. Cheers Dave

X2Go Client connection issue (Socket error)
by Melroy van den Berg 18 May '20

18 May '20

Hi X2go devs, Package: x2goclient Version: 4.1.2.2 (Linux Mint based on Ubuntu Bionic, using PPA) I often get an error message when I try to connect to my Debian buster docker image, running x2goserver and XFCE, via the X2Go Client on my host machine. It will give the following error message (when using the --debug flag on the x2goclient): x2go-DEBUG-../src/sshmasterconnection.cpp:2071> "ssh_channel_open_session failed": "Socket error: No such file or directory" x2go-DEBUG-../src/sshprocess.cpp:478> I/O error: "ssh_channel_open_session failed."" - Socket error: No such file or directory" (0). I created a detailed video, I posted it on YouTube, please take a look at the video: https://youtu.be/LAlLtBNTIUo Logging details, reproducibility and more is explained in the video itself. You'll notice that I can sometimes connect to the XFCE session and sometimes I can't. Although connecting via the ssh cli command is always working without any issues. Meaning there is really some kind of bug in the X2Go Client. I'm afraid. Again, I really hope somebody could help me in finding the root-cause and fixing the issue. Since I really love X2Go. And I would like to use this tool in production. I'm also a software developer so maybe I can help debugging the problem. Similar (same) bug is reported in the past (from 2019): https://lists.x2go.org/pipermail/x2go-user/2019-March/005512.html All the details regarding this Docker image and setup can be found in this git repo: https://gitlab.melroy.org/melroy/xfcevdi See attachments for additional debug logs of the client itself. One when successful and one during the error. Thanks in advance! Kind regards, Melroy van den Berg Ps. You can contact me by mail of course. But I can understand that debugging this issue would be preferable be done via VoIP for example.

Bug#1451: Issue with some GUI elements not being drawn
by Costanzo, Ian M. 06 May '20

06 May '20

Package: x2go-client Version: 4.1.2.2 Client Setup: Manjaro Linux 19.0.2 x2go-client 4.1.2.2 Server setup: CentOS Linux 7.7.1908 (Core) x2goserver 4.1.0.3 x2goserver-xsession 4.1.0.3 NXagent 3.5.99.17c Hello, I have been experiencing an issue where some gui elements (dropdown menus or popup windows) are not being drawn. In some instances (dropdown menu) it is still navigable and submenus will (sometimes) be drawn. Other instances like pop-up menus are not accessible if not drawn. Checking application logs, it appears the window was successfully launched but the X server isn't drawing it? Not sure, any insight would be appreciated.

Bug#1465: Allow running with restricted shell (rbash), or limit applications that can be run.
by Vladislav Kurz 04 May '20

04 May '20

Package: x2goserver Version: 4.1.0.3-0~1708~ubuntu16.04.1 Severity: wishlist Hello all, we are using x2go to run a single application on remote server, and we want to lock all other access as much as possible. Essentially, we'd like to ensure that even if the user connects via SSH, he could start only one (or limited set) of applications. I found this guide https://wiki.x2go.org/doku.php/wiki:security:rbash but it seems to be somewhat outdated. I followed the instructions, created the wrapper command, set up the symlinks, and configured ssh, but then I get this error: Connection failed. rbash: bash: command not found Apparently x2go client is trying to execute "bash /usr/bin/x2goruncommand" instead of just "x2goruncommand". If I add bash to the path with allowed commands, it starts working. But it makes the whole use of rbash pointless. Also it allows me to run anything via x2go anyway - as x2goruncommand is a bash script, it escapes the restrictions of rbash. Is it possible to update that wiki page with current requirements - what commands are necessary in $PATH for restricted shell ? I found that at least nxagent should be there too. And to modify the login sequence so that bash is not needed in $PATH ? BTW is that defined on server or client? Where exactly? I also found a nice feature "published applications" https://wiki.x2go.org/doku.php/wiki:advanced:published-applications It would be nice, if the x2go server had a config option, allowing users to run only the "published applications", or use some other list of allowed commands. So far my attempts at limiting the access to other applications was not very successful. There's a lot of stuff needed internally by x2go, so I cannot just remove execute bit from many commands in (/usr)/bin/ Thanks for any advice or hotfix. Best Regards Vladislav Kurz

Bug#1454: Better explain fullscreen keyboard shortcuts usage on multi display setup
by Olivier Gauthier 04 May '20

04 May '20

Package: wiki.x2go.org Add missing keyboard shortcut Shift + Ctrl + Alt + F to x2goclient documentation. I spent an hour trying to figure why my X2Go session would not want to go fullscreen over all my screens like I normally do. I realized I always used Ctrl + Alt + F to go fullscreen as explained at https://wiki.x2go.org/doku.php/doc:usage:x2goclient. That gave me fullscreen session spanning over all multi display screens as expected. However, without noticing it, I started using Shift + Ctrl + Alt + F this morning because my muscle memory have been trained while using Guacamole menu shortcut (uses Shift-Ctrl-Alt keys to toggle menu). I did not notice at first, because Shift + Ctrl + Alt + F also works on X2Go Client, but it only go fullscreen on current display screen. It puzzled me for a while today, so I went back to wiki page, to figure I have been using wrong shortcut. I verified code for key bindings (https://code.x2go.org/gitweb?p=nx-libs.git;a=blob;f=etc/keystrokes.cfg;hb=H…) and it effectively offers two clever options to go full screen on multi displays. > 4 <keystroke action="switch_all_screens" Control="1" AltMeta="1" key="f" /> > 5 <keystroke action="fullscreen" Control="1" Shift="1" AltMeta="1" key="f" /> Here is two wiki patches to help clarify documentation around full screen usage on multi display setups. Feel free to rephrase any way you want. -- Olivier -- doc/usage/x2goclient.txt 70c70,71 < * Ctrl + Alt + F: toggle fullscreen/windowed --- > * Ctrl + Alt + F: toggle windowed/fullscreen over all screens > * Shift + Ctrl + Alt + F: toggle windowed/fullscreen on current screen only doc/usage/multi-display.txt 19a20,26 > > ===== Use keyboard shortcuts to go fullscreen over one or all displays ===== > > There is two different ways to enter fullscreen from keyboard shortcuts. One goes fullscreen over all screens, the other goes fullscreen only on current screen. > > * Ctrl + Alt + F: toggle windowed/fullscreen over all screens > * Shift + Ctrl + Alt + F: toggle windowed/fullscreen on current screen only

Bug#1450: Fwd: Arrow keys randomly stop working in x2go
by stivstivsti . 03 May '20

03 May '20

Package: x2goclient Version: 4.1.2.2 I am connecting from Ubuntu Linux 18 to another Ubuntu linux machine with x2go. Connection works, but some keys don't, especially arrow keys. When I press up arrow, it starts screen capture: [image: image.png] I tried some recipes from this question: https://serverfault.com/questions/582552/x2go-arrow-key-is-not-working-prop… but they don't help. *setxkbmap us -print | xkbcomp - $DISPLAY* -- doesn't fix the problem. I tried to play with keyboard settings here: [image: image.png] but it doesn't help also. How can I fix it? I've followed instruction from wiki.x2go.org updating x2goclient to 4.1.2.2-0~1913~ubuntu18.04.1 and x2goserver to 4.1.0.3-0~1708~ubuntu18.04.1. The problem is still there.

Bug#1456: Local window manager misbehaves when X2Go windows are open.
by Itay Chamiel 01 May '20

01 May '20

Package: x2goclient Version: 4.1.2.2 or 4.1.1.1 Environment: Client: Ubuntu 18.04 LTS, 64-bit, freshly installed and fully updated, running X2Go Client v. 4.1.2.2 (Qt - 4.8.7). Machine is a Dell Vostro 15 3000 laptop, with an external monitor connected and the lid shut. Server OS: Ubuntu 16.04.1 LTS, x2goserver 4.1.0.3 Steps to reproduce: 1. Start with a typical local desktop session (tested on default Ubuntu desktop as well as Cinnamon), with at least one window open (say, a web browser or email client). 2. In X2Go define a session: set the session name, host, login, check "try auto login". Session type: Single application, choose "Terminal" from the drop-down. 3. Start this session. X2Go will connect and a "Konsole" window will appear. [note: if you get a different terminal, go back to step 2 and type "konsole" as the requested remote application. Konsole is not the only terminal to exhibit this bug but is the easiest to reproduce it with.] 4. Type something in the terminal, "hello", whatever. 5. Now try to switch to another window using Alt-Tab or clicking on the task bar icon representing that window. When I perform these steps the requested window does not appear and the Konsole remains on top and in focus. The only way to return to normal behavior is to minimize the Konsole window.

Bug#1466: x2gokdriveclient not packaged for windows
by Михайло Падалка 24 Apr '20

24 Apr '20

Package: x2goclient Version: 4.1.2.2 X2GoClient installer for windows has no x2gokdriveclient.exe packaged, but has an option "Run in X2GoKDrive (experimental)" available. That's at least confusing, as it will never work. Either x2gokdriveclient should be packaged (preffered, as X2GoKDrive works better for modern desktops), or that option should be not available on Windows.

Bug#1458: unattended Debian installations (using preseed) fail when x2gobroker-ssh is involved
by Stefan Baur 21 Apr '20

21 Apr '20

package: x2gobroker-ssh version 0.0.4.1 severity: important The postinst file for x2gobroker-ssh contains a check to see if the nscd binary is somewhere in the path. If it is, then nscd -i group is called, to purge the group cache (which makes sense, as a new group has been added in a previous step, so the cached information is outdated). If it is not, then it is assumed that nscd is not installed, thus, no group information is cached, and thus, no purge is needed. This fails to take into account that nscd might be (freshly) installed, but not running. Which is the case during a preseeded Debian installation (and probably when running debootstrap as well). The result is that "nscd -i group" is called even though nscd isn't active at the moment. Which triggers a return code of "1". Which in turn causes the postinst script to report "1" as its return code. This, of course, gets passed back up to the debian-installer, which decides to abort the installation, as it seems that something went wrong during installation of the package. The patch is rather simple: Instead of checking for the presence of the executable in the file system, check if it is currently running: - if which nscd 1>/dev/null; then + if ps -C nscd 1>/dev/null; then As this is currently breaking all automated x2gobroker-ssh installs, I would suggest releasing a new version containing only this patch ASAP, if a full release with all changes since the last proper release of x2gobroker-ssh would bring too many changes at once for a timely release.

Bug#1459: X2GoMiniSSHBroker
by Stefan Baur 20 Apr '20

20 Apr '20

package: x2gobroker priority: wishlist Hi everyone, A while ago, I wrote a small broker demo in bash. I would like to get this added to X2Go's official repository, in the x2gobroker.git tree, as a separate binpkg (maybe called x2gobroker-ssh-mini). Limitations: 1) This script is not suitable for a multi-server setup. It needs to run on the only X2GoServer there is. (There's an idea in the comments how to overcome this limitation, though.) This is, however, also its advantage: You don't need to mess with LDAP, postgres and NFS just to be able to use a central configuration for your X2GoClients. 2) It does not offer all the ACL options of the "big" broker implementations. Problems: 1) There's currently no manpage for it. All documentation is in the comments in the bash script. 2) IIRC, Alex made some changes to X2GoClient and/or X2GoServer that will cause this script to break - however, these changes are not part of our stable release yet. So it should be possible to release this package right now, but it needs to be kept in mind that it will have to be adapted once Alex' changes make it to stable. This was related to more "chatter" about "Access granted" and similar status messages being exchanged between server/broker/client. Script attached.
