Bug#1357: pyhoca 0.6.0.1 incompatible with x2goserver 4.1.0.3
by Chris Greenshields 30 May '23

30 May '23

Package: Pyhoca Version: 0.6.0.1 I tested all combinations of the following recent releases of the following software from the ppa:x2go/stable and ubuntu repositories: + x2goserver + 4.1.0.0-3 (ubuntu) + 4.1.0.3-0~1708~ubuntu18.04.1 (ppa:x2go/stable) + x2goclient + 4.1.1.1-2 (ubuntu) + 4.1.2.1-0~1788~ubuntu18.04.1 (ppa:x2go/stable) + pyhoca-cli + 0.5.0.4-1 (ubuntu) + 0.6.0.1 (ppa:x2go/stable) There is one combination that did not work: x2goserver 4.1.0.3-0~1708~ubuntu18.04.1 (ppa:x2go/stable) with pyhoca-cli 0.6.0.1 (ppa:x2go/stable) It failed with the following message, which I assume is a bug: " a bytes-like object is required, not 'str' pyhoca-cli: error: the remote server does not have the X2Go Server software installed "

Bug#1228: Ctrl-Alt-T doesn't terminate connection in "local desktop" sessions
by Alexey Nemov 30 May '23

30 May '23

Package: x2goserver Version: 4.0.1.20 Summary: As stated in the wiki https://wiki.x2go.org/doku.php/wiki:advanced:nx-keyboard-shortcuts The action "close_session" should terminate the session. But, pressing Ctrl-Alt-t in a "local desktop" session does not "terminate" the session. Steps to reproduce: 0. Create a new session profile in x2goclient with session type "Connect to local desktop"; 1. Connect to remote computer using this session profile; 2. Press Ctrl-Alt-t at the client. Expected behaviour: The remote desktop window on the client should close, the connection should be terminated. Actual behaviour: The remote desktop window on the client does not close, the connection is not terminated. The following log entries appears in the server's system journal: ``` Oct 26 13:50:39 localhost /usr/bin/x2gosuspend-session[31790]: session with ID alex-50-1508997021_stS1XSHADalexXSHADPP0_dp24 has been suspended successfully Oct 26 13:50:45 localhost su[31900]: Successful su for alex by root Oct 26 13:50:45 localhost su[31900]: + ??? root:alex Oct 26 13:50:45 localhost su[31900]: pam_unix(su:session): session opened for user alex by (uid=0) Oct 26 13:50:45 localhost systemd-logind[508]: New session c99 of user alex.

Bug#1427: Update Tumbleweed packages for Perl 5.30
by Tristan Miller 28 Sep '21

28 Sep '21

Package: x2goserver Version: 4.1.0.4 Tags: rpm-packages Various openSUSE Tumbleweed packages for the X2Go server are built in such a way that they require Perl 5.28.1. However, Tumbleweed no longer distributes that version of Perl; it now distributes only Perl 5.30.1. This means that it is impossible to install these X2Go server packages on the most recent release of Tumbleweed, and for Tumbleweed systems where those X2Go server packages were already installed, it is impossible to upgrade Tumbleweed without removing the X2Go server: $ sudo zypper dup [sudo] password for root: Loading repository data... Reading installed packages... Warning: You are about to do a distribution upgrade with all enabled repositories. Make sure these repositories are compatible before you continue. See 'man zypper' for more information about this command. Computing distribution upgrade... 9 Problems: Problem: x2goserver-common-4.1.0.4-0.0x2go1.0.git20191106.1811.heuler.x86_64 requires perl(:MODULE_COMPAT_5.28.1), but this requirement cannot be provided Problem: perl-5.28.1-3.4.x86_64 requires perl-base = 5.28.1, but this requirement cannot be provided Problem: perl-X2Go-Server-DB-4.1.0.4-0.0x2go1.0.git20191106.1811.heuler.x86_64 requires perl(:MODULE_COMPAT_5.28.1), but this requirement cannot be provided Problem: perl-X2Go-Server-4.1.0.4-0.0x2go1.0.git20191106.1811.heuler.x86_64 requires perl(:MODULE_COMPAT_5.28.1), but this requirement cannot be provided Problem: perl-X2Go-Log-4.1.0.4-0.0x2go1.0.git20191106.1811.heuler.x86_64 requires perl(:MODULE_COMPAT_5.28.1), but this requirement cannot be provided Problem: x2goserver-4.1.0.4-0.0x2go1.0.git20191106.1811.heuler.x86_64 requires perl(:MODULE_COMPAT_5.28.1), but this requirement cannot be provided Simply telling zypper to keep the obsolete packages doesn't work as this ends up in a rabbit-hole of seemingly irresolvable dependency issues.

Bug#913: Inaccurate scaling of dialog boxes and fonts for large DPI screen in Windows 10
by Alves-Foss, James (jimaf＠uidaho.edu) 02 Aug '21

02 Aug '21

Package: x2goclient for windows Version: 4.0.5.0 Downloaded new version of x2goclient for a new Dell Laptop. Screen resolution 3200x1800. OS Windows 10 (just checked, same problem on similar machine in Windows 8.1) When I open the main program, the fonts and windows do not scale well in the session selection boxes When I create a new session and try to open it, I can not see the list of open sessions to connect to. This appears to be a scaling issue for high DPI systems. I tried Windows 7, Windows 8 compatibility modes. I tries to disable display scaling on high DPI systems (see attached images)

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#1369: Keys do not release when using Emacs in X2GO Client
by Yan Zhang 03 May '21

03 May '21

Package: x2goclient Version: 4.1.2.0 I am using Emacs 24.5.1 with x2go client version 4.1.2.0 in Windows 10. My server OS is Ubuntu 16.04 and the x2goserver comes from the PPA repo. The problem happens if I hit "ctrl+space" to start mark region in Emacs and then press down "ctrl+n" to scroll down the region for a few seconds. Usually after I release "ctrl+n", Emacs will leave the currently marked region for further commands. But in the reported version of client, Emacs keeps scrolling down until it reaches the end of the file. There is no way to stop it within Emacs (e.g., "ctrl+g"). I have tried to move the cursor by keeping "ctrl+n" pressed down. This issue does not happen after I release the key. This issue happens when the session type is either "XFCE" or "published application". I have not tested other session types as I do not have an environment for that. And client version 4.1.1.1 does not seem to have this issue. Thanks and regards, Yan

Bug#1386: Popup plasmoids flicker and disappear when a remote application is in focus
by Tristan Miller 23 Mar '21

23 Mar '21

Package: x2goclient Version: 4.1.1.1 I use X2Go to run single applications remotely and have them appear on my local Plasma desktop. When such a remote application window has focus, it prevents me from opening most pop-up plasmoids on my local machine. The plasmoids flicker and then disappear. STEPS TO REPRODUCE 1. Use X2Go to launch a single application remotely. 2. Give the remote application focus (for example, by Alt-Tabbing to it or clicking on it). 3. Do some action that causes a local plasmoid window to pop up. For example, click on the Application Launcher to try to show the application list, or click on the Digital Clock to try to show the calendar, or click on a group entry in the Task Manager to try to show the list of windows, or press Alt+F2 to try to bring up KRunner. OBSERVED RESULT 4. The popup window appears for a few milliseconds and then disappears. EXPECTED RESULT 4. The popup window should appear and then persist. SOFTWARE/OS VERSIONS KDE Plasma Version: 5.12.8 KDE Frameworks Version: 5.45.0 Qt Version: 5.9.4 OS: openSUSE Leap 15.0 x2goclient: 4.1.1.1 x2goserver: 4.1.0.4 ADDITIONAL INFORMATION The video at <https://bugs.kde.org/attachment.cgi?id=119625> shows the bug. It shows a portion of my Plasma panel that includes the Application Launcher, the Pager, and part of the Task Manager. Claws Mail is running remotely via X2Go and one of its composer windows has focus. I am clicking repeatedly on the Application Launcher. You can see the pop-up window briefly flickering and disappearing. As far as I can tell, the problem happens only when an application run via X2Go has focus. The problem is not reproducible with applications run remotely via plain SSH. Not sure if this is a KDE/Plasma problem or an X2Go problem, so I have reported this also on the KDE Bugzilla: <https://bugs.kde.org/show_bug.cgi?id=406882>
