Bug#581: VirtualBox Clipboard Sharing does not work when accessing the host over X2Go
by Michael DePaulo 18 Jun '21

18 Jun '21

Package: nx-libs Version: 3.5.0.27 Severity: normal If you run a VirtualBox VM with its display running under X2Go, the VM's clipboard sharing fails to work in either direction. You cannot copy and paste text between the VM and an app running under X2Go server, nor can you copy and paste text between the VM and an app running on the X2Go Client system. (I believe VirtualBox VMs use SDL to interact with the X server, which in this case is nxagent. This differs from the VirtualBox GUI, which is written in QT.) Specifically, when the X sesssion starts on the guest, a VirtualBox-provided script for X calls "VBoxClient --clipboard" to start the clipboard service. The service runs as the user logged into the guest. However, this service fails to stay running, and thus the clipboard sharing does not work. If you launch the VirtualBox VM on the local X.org X server, the guest's clipboard service stays running and clipboard sharing works. You can also launch the VM in RDP headless mode from x2go (so the VM does not render its display to any nxagent). In this use case, the clipboard service stays running and clipboard sharing works. The strange part is that the configuration of the host affects the behavior of the guest. It makes sense though because it's a bug in the guest's code to integrate with the host. Also, when you do call "VBoxClient --clipboard", it returns 0. And if you call it after the X11 session has already started, the problem still occurs. In x2goclient, I tried turning on and off the following setting, but it had no effect: Options -> Settings -> X-Server settings -> do not use primary clipboard My theory is that this is a bug in nx-libs, and that the bug is probably related to nx-libs being forked from such an old X.org codebase. It is worth looking into whether other SDL apps have clipboard trouble with X2Go on Ubuntu 14.04. (It's also worth testing an older release of Ubuntu as the host OS, since it would have an older release of SDL.) Host system: OS: Ubuntu 14.04.1 64-bit with latest bugfix & security updates nxagent: 2:3.5.0.27-0~446~ubuntu14.04.1 x2goserver: 4.0.1.15-0~847~ubuntu14.04.1 x2goserver-xsession: 4.0.1.15-0~847~ubuntu14.04.1 VirtualBox 4.3.14 (from download.virtualbox.org) "Shared Clipboard" is set to "Bidirectional" for the VM $ cat /etc/x2go/x2goagent.options | grep -v '^#' | grep -v '^$' X2GO_NXAGENT_DEFAULT_OPTIONS="" X2GO_NXAGENT_DEFAULT_OPTIONS+=" -extension XFIXES" X2GO_NXAGENT_DEFAULT_OPTIONS+=" -nolisten tcp" Guest OS: Ubuntu 12.04.5 64-bit with precise HWE stack, the virtual kernel, and all the latest bugfix & security updates OS-provided XFCE virtualbox-guest-dkms: 4.1.12-dfsg-2ubuntu0.6 virtualbox-guest-utils: 4.1.12-dfsg-2ubuntu0.6 virtualbox-guest-x11: 4.1.12-dfsg-2ubuntu0.6 Configured according to: https://github.com/mikedep333/duckpan-vagrant/tree/duckduckhack-vm The aforementioned script is: /etc/X11/Xsession.d/98vboxadd-xclient (I'm sure a different script would be used for distros like CentOS which lack the /etc/X11/Xsession.d/ folder).

Bug#1072: X2Go Client: top 24 pixels in fullscreen session do not respond to mouse clicks
by Chris Martin 09 Feb '21

09 Feb '21

Package: x2goclient Version: 4.0.5.1 I am trying to start a full screen X2Go session which 1. takes up the entire display, and 2. responds to my mouse clicks everywhere in the session, but cannot accomplish this with any combination of settings. Client OS: Debian Jessie / 8 / Stable, GNOME 3 desktop environment Client X2Go Client: 4.0.5.1 and 4.0.3.1 Server OS: Xubuntu 16.04 LTS Server x2goserver version: 4.0.1.19 Server x2goserver-xsession version: 4.0.1.19 When I choose "fullscreen", I get different behavior intermittently: 1. The client spawns across the entire screen but the *top panel inside the X2Go session* does not respond to any mouse clicks. I suspect the panel in my GNOME session running the X2Go client (which occupies the same pixels behind the panel inside the X2Go session) is stealing mouse focus. My mouse pointer turns black instead of white when I hover over the top 24 pixels or so, inside the X2Go session. 2. The client spawns what I would call a "maximized window". The top of the screen is still consumed by the title bar of the X2Go window, and the panel of the enclosing GNOME session in which the X2Go client is running. I have observed both cases 1 (most common) and 2 with X2Go Client 4.0.5.1, and only case 1 with X2Go client 4.0.3.1. When I choose "Display 1" in the Input/Output settings, the X2Go session displays only in the upper-left quadrant of my display; the rest of the screen is black. Thank you, Chris Martin

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#1217: X2GoClient does not auto-resume sessions in public application mode
by Stefan Baur 01 Mar '20

01 Mar '20

package: x2goclient X2Goclient is supposed to auto-resume a suspended session if the following conditions are all met: - The session settings provided by X2GoClient upon connect match the session settings of the suspended session, AND - There is exactly one suspended session with matching settings, AND - X2GoClient was NOT started with --no-autoresume However, this fails for sessions of the "published application" type, and the reconnect session chooser popup is shown. Desktop sessions and single application sessions are not affected. -- 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

Bug#1230: x2go fails unhelpfully when a session fails to start
by Norman Gray 28 Feb '20

28 Feb '20

Package: x2goserver Version: 4.0.1.20 When a username is rejected by the 'valid username' test (see separate bug report<https://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=1229>), the session doesn't fail, but simply seems to hang, giving no feedback about the problem, nor, as far as I can see, reporting anything in the logs. To reproduce, attempt to log in using a username such as '123x'. The session doesn't complete the setup, leaving the user at a blank screen. Suggestion: a user-visible error message should be produced, and an informative message sent to the system log. Best wishes, Norman -- Norman Gray : https://nxg.me.uk

Bug#1320: >=libssh-0.8.0 does not provide libssh_threads.so anymore
by Bernard Cafarelli 12 Feb '20

12 Feb '20

Package: x2goclient Version: 4.1.2.1 With recently released libssh 0.8.0 (and bugfix 0.8.1), everything is now provided in libbsh.so only. The separate libssh_theads.so library was dropped. This breaks x2goclient linking, as the project file explicitly sets: LIBS += -lssh -lssh_threads A proper fix would be to check libssh version and only append "-lssh_threads" for < 0.8. Currently in Gentoo libssh package added a compatibility symlink to workaround the failures in impacted consumers.

Bug#1305: bad window title encoding for Unicode (Cyrillic) session names
by Ivan Zakharyaschev 24 Dec '19

24 Dec '19

Package: x2goclient Version: 4.1.1.1 Tag: patch If the session name is written in Cyrillic (I guess, any Unicode), the window title is displayed incorrectly (as if Unicode was not understood, with strange symbols) in the task bar in the KDE panel. See the attached screenshot (made by mcpain@). Patch (by mcpain@ and zerg@) is attached, too: x2goclient-4.1.1.1-window-title-encoding.patch The client and server OS are: ALT Linux (Sisyphus or p8). The window manager is KDE.
