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)

Pull request: add --nofork option to x2gocleansessions
by Andrew J. Hesford 27 Jun '21

27 Jun '21

Greetings, Following is a pull request against the 4.1.0.x branch that separates the no-fork behavior of x2gocleansessions from the debug output behavior. A new flag, `--nofork` (`-n-` for short) determined whether the program forks; `--debug` only controls the logging verbosity and also forces `$nofork=1` to preserve old behavior. Please let me know if anything should be changed. Thanks, Andrew Hesford The following changes since commit cabad60865be64de219b3b477ddaefa6aef1cf43: Continue development (2018-11-29 08:09:45 +0100) are available in the Git repository at: https://github.com/ahesford/x2goserver.git nofork for you to fetch changes up to 4587d918c138205c252316c007fab31b75b87061: Separate non-forking behavior from --debug into --nofork (2021-05-11 19:27:02 -0400) ---------------------------------------------------------------- Andrew J.

Bug#1487: sftp-server is missing message (I do not need filetransfer)
by Zounp 24 Jun '21

24 Jun '21

Hello, This issue is still applicable. This is not a bug but a safety request. For my application I do not need folder sharing nor printing support. So I did not install: rdesktop, openssh-server nor openssh-sftp-server on the client computer Installing a server is a security risk. I do not want to install servers on my client computer (on which I am running x2goclient) So it is not a big issue but it is still annoying. So it would be so nice if the need for the sftp-server (folder sharing nor printing support) can be made optional via a setting for instance. Thanks for X2Go. Thanks. -- Met vriendelijke groet, Zounp

Re: [X2Go-Dev] X2Go HTML plugin

Hi Alex, On Mi 21 Apr 2021 22:43:53 CEST, Oleksandr Shneyder wrote: > https://wiki.x2go.org/doku.php/wiki:advanced:x2gohtmlclient I am currently trying to provide an out-of-the-box DEB installation of x2gohtmlclient. For this, I need to make some adjustments, mainly these are about wss: traffic becoming optional and defaulting everything to localhost with ws: protocol. Of course, in real world deployments, this needs to SSL'ified again. But I'd really love to provide DEBs that demo x2gohtmlclient out-of-the-box (and SSL certificates are not so much things that come out of the box). This all seems to work fine, only that I get a failure when x2goclient.min.js starts communicating with the x2gokdrive Xserver (via x2gowswrapper, via websockify). I think that my seen bug is caused by my websockify 0.9 which has the text data mode removed (compared to earlier versions). See: https://github.com/novnc/websockify/issues/365#issuecomment-432270758 As I am testing everything on Debian 11, I indeed have websockify 0.9 installed. Where did you test the whole stack of x2gohtmlclient, x2goclient.min.js, x2gowebrpc and x2gowswrapper on? Debian 10, maybe? My symptom in the browser is: - Logon works - X2Go KDrive sessions starts in the background (processes come up, desktop is resumable via native X2Go Client later on) - X2Go Logo appears in the placeholder area in the webbrowser - X2Go session strings is shown at the top of the session window in the browser - and then, the session is immediately closed again. The (error) message(s) I get in the browser console while this happens are/is these/this: ``` WS Open Event {isTrusted: true, type: "open", target: WebSocket, currentTarget: WebSocket, eventPhase: 2, …} x2goclient.min.js:208 Sending geometry event: ArrayBuffer(41) Uint32Array(5) [7, 60294400, 0, 0, 0] Uint16Array(5) [7, 0, 1280, 920, 0] x2goclient.min.js:204 Sending client Version and OS: ArrayBuffer(41)byteLength: (...)__proto__: ArrayBuffer[[Int8Array]]: Int8Array(41)[[Uint8Array]]: Uint8Array(41)[[ArrayBufferByteLength]]: 41[[ArrayBufferData]]: "0x0fc800a0c030" Uint32Array(5) [10, 196612, 0, 0, 0]0: 101: 1966122: 03: 04: 0buffer: (...)byteLength: (...)byteOffset: (...)length: (...)Symbol(Symbol.toStringTag): (...)__proto__: TypedArray Uint16Array(5) [10, 0, 4, 3, 0]0: 101: 02: 43: 34: 0buffer: (...)byteLength: (...)byteOffset: (...)length: (...)Symbol(Symbol.toStringTag): (...)__proto__: TypedArray x2goclient.min.js:265 WS Close CloseEvent {isTrusted: true, wasClean: true, code: 1003, reason: "Unsupported: Text frames are not supported", type: "close", …} ``` Before I dig any deeper, could you try your test setups with websockify 0.9 and report back if you see a similar error popping up or not?

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).

X2Go Client Nightly builds for debian bullseye
by Oleksandr Shneyder 16 Jun '21

16 Jun '21

Hi guys, I just checked the Jenkins and I could see that there are some issues building the X2Go Client heuler packages for bullseye. Looks like the problem is in qt4 build dependencies, which is not available in bullseye anymore. I don't want to get involved in the packaging process, but I think it's very important to have the nightly builds working for debian testing. What do you think about it? 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.
