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

Packing methods
by Ulrich Sibiller 06 Apr '21

06 Apr '21

Hi, in the source code of x2goclient you can find the list of supported image compression methods (in res/txt/packs). After checking back with what I documented for nx (see https://github.com/ArcticaProject/nx-libs/issues/802) there are some compression methods that are _not_ supported by nx: 256-rdp 256-rdp-compressed 32k-rdp 32k-rdp-compressed 64k-rdp 64k-rdp-compressed 16m-rdp 16m-rdp-compressed rfb-hextile rfb-tight rfb-tight-compressed 8-tight 64-tight 256-tight 512-tight 4k-tight 32k-tight 64k-tight 256k-tight 2m-tight 16m-tight Judging from their name they seem to be related to Windows Remote Desktops and VNC. I read somewhere that x2goclient once offered rdp support but AFAICS it does no longer offers/supports that. So are these compression methods obsolete or am I missing something here? What about the compression settings for x2gokdrive? Uli

X2go client window misplaced in LXQt
by Kalle Tuulos 02 Apr '21

02 Apr '21

I'm running Lubuntu 20.04, which has LXQt. The X2go client has been installed using apt method, current version is 4.1.2.2. When the X2Go client is opened and closed, on the next time, it will open on 30 pixels higher and 2 pixels left position, than the earlier position. This can be seen from file ~/.x2goclient/sizes: Before opened: [mainwindow] maximized=false pos=@Point(275 170) size=@Size(1017 600) Window is not moved, just closed: [mainwindow] maximized=false pos=@Point(273 140) size=@Size(1017 600) Opened and closed again, not moved: [mainwindow] maximized=false pos=@Point(271 110) size=@Size(1017 600) This same problem is in many Qt based applications, so this is not X2go problem as such, but on the Qt framework. Also, this same problem was already on 18.04 version of Ubuntu, on another computers. I have a workaround for this - the sizes files is overwritten on each login with a valid one. Is there any more clever fix for this? BR, Kalle -- - Kalle

GitLab Install LXC - Update (issue)
by Melroy van den Berg 01 Apr '21

01 Apr '21

Hi all, I tried to omnibus GitLab install on the VM. Failed on: Expected process to exit with [0], but received '255' ---- Begin output of sysctl -e -p /opt/gitlab/embedded/etc/90-omnibus-gitlab-kernel.shmmax.conf ---- STDOUT: STDERR: sysctl: setting key "kernel.shmmax": Read-only file system ---- End output of sysctl -e -p /opt/gitlab/embedded/etc/90-omnibus-gitlab-kernel.shmmax.conf ---- Ran sysctl -e -p /opt/gitlab/embedded/etc/90-omnibus-gitlab-kernel.shmmax.conf returned 255 Due to: command "sysctl -e -p /opt/gitlab/embedded/etc/90-omnibus-gitlab-kernel.shmmax.conf" causing the error: sysctl: setting key "kernel.shmmax": Read-only file system Read-only of the /sys/ directory is typical the case with LCX containers... But the advice value of the shmax is: cat /opt/gitlab/embedded/etc/90-omnibus-gitlab-kernel.shmmax.conf kernel.shmmax = 17179869184 I can complete the setup if you want, by using a workaround by commenting-out the related section in: /opt/gitlab/embedded/cookbooks/cache/cookbooks/package/resources/gitlab_sysctl.rb. And run: gitlab-ctl reconfigure. But I rather like to get this working in a correct manner. Maybe somebody add at this shmmax statement above to the host /etc/sysctl.conf file? Let me know if somebody can help me with this or which direction you want to go. Ps. where are not the only one on the internet: http://letmegooglethat.com/?q=STDERR%3A+sysctl%3A+setting+key+%22kernel.shm… Thx! Kind regards, Melroy van den Berg

x2goagent segfaults with x2goclient from ubuntu 20.10
by Kenneth Johansson 01 Apr '21

01 Apr '21

so I have been using x2go for years and its works fine for what I need but today it stopped working. the error message was not really clear so I deleted and reinstalled (server and client) but still no go. Turns out its the x2goagent that segfaults on the server side. The client is an ubuntu 20.10 and the servers I tested with is debian 10 and ubuntu 20.04. To make sure that there was no version mismatch I then installed the server on the ubuntu 20.10 computer and tried to connect to localhost and still get the segfault. how to debug this ?? what I try to do is use a single application and start "command=/usr/bin/xterm" since its not working even to localhost this should be something that a lot more people have a problem with than just me. I have deleted all configurations for both server and client and the only thing I change when I create a new session is the host login session type. So I do not see how I could have made something wrong here.

Bug#1535: users randomly (but repeatedly) get a "libx2go-server-db-sqlite3-wrapper insertsession" error at connection attempts
by Enrico Bertocchi 27 Mar '21

27 Mar '21

Package: x2goserver Version: Devuan Beowulf package x2goserver/stable,now 4.1.0.3-4 Dear sirs, I'm currently employing x2go (Devuan Beowulf package x2goserver/stable,now 4.1.0.3-4) to operate a terminal server for computer lab lessons. It randomly happens that some of the students experience sequences of failed connection attempts (usually 5-10 in a row) with the following kind of error (typed from a typical screenshot) [...] n283287-55-1616084795_stDmwm_dp32 at /usr/share/perl5/X2Go/Server/DB.pm line 251. : /usr/lib/x2go/libx2go-server-db-sqlite3-wrapper insertsession 55 x2go-cdm [...] n283287-55-1616084798_stDmwm_dp32 at /usr/share/perl5/X2Go/Server/DB.pm line 251. : /usr/lib/x2go/libx2go-server-db-sqlite3-wrapper insertsession 55 x2go-cdm n283287-55-1616084799_stDmwm_dp32 at /usr/share/perl5/X2Go/Server/DB.pm line 251. Unable to find free display port or insert new sessions into database; parameters: port(55), hostname (x2go-cdm) and session name (n283287-55-1616084799_stDmwm_dp32). A further, subsequent connection attempt randomly succeeds instead. At the same time, other students experience regular login procedures. The student passwd data is taken from a "sssd-ldap" domain, fact this that might cause some of the quirks. Please indicate me which further data on the server side might be relevant for investigating the problem. Thanks. -- Enrico Bertocchi

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>

Bug#1527: native X11 fonts stop being rendered as the desktop is shared; functionality is restored on unsharing.
by Enrico Bertocchi 27 Feb '21

27 Feb '21

Package: x2goserver Version: 4.1.0.3-4 (amd64, devuan Beowulf) Running, let's say "xfd -fn fixed" or any other sofware whose GUI is based on native X11 fonts (mwm) from within a remote x2go session (DISPLAY=:50), strings are rendered correctly until a second connection to such display (via the "x2go/x11 Desktop Sharing" facility) is established on the same :50 display, even with the same user. As soon as the connection is established, X11 fonts rendering stops for both the clients and all X11 clients which rely on such feature (e.g. mwm, or xfd) are shown with blank text boxes; applications which rely on different font technologies (e.g. the sakura terminal) are not affected. As soon the second connection is closed, font rendering is restored for the initial client, and writings reappear on the next window refresh. Such behavior is consistently reproduced at every attempt. Both client connections are originated from the same Centos 8 machine, with x2goclient 4.1.2.2 and disabled "set display DPI setting" option. Sincerely -- Enrico Bertocchi

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

Upcoming Debian 11 freeze
by Mike Gabriel 27 Jan '21

27 Jan '21

Hi Mihai, Stefan, Alex, Uli, etc. the Debian 11 freeze is ahead (last uploads of new upstream releases are possible on Feb 6th/7th). I'd like to see some of the X2Go components released before that date (esp. the x2gothinclient, x2goclient, x2goserver and also nx-libs (already discussed with Uli)). @Mihai: is that a feasible thing to do???

Bug#1495: x2goclient resumes existing session with wrong X-Server options
by Maarten Boekhold 09 Dec '20

09 Dec '20

Package: x2goclient Version: 4.1.2.2 Windows 10, x2goclient 4.1.2.2 When resuming a "paused" x2Go session, x2goclient is using the wrong X-Server settings. I have configured my x2goclient with the following settings for X.Org Server settings: **X.Org Server settings** [X] use custom X-Server Executable: C:/Program Files (x86)/x2goclient/VcXsrv/vcxsrv.exe [ ] start X-Server on X2Go Client start Window mode: -screen 0 %wx%h -notrayicon -clipboard -keyhook \ -nowinkill -nopn -silent-dup-error Fullscreen mode: -fullscreen -notrayicon -clipboard -keyhook \ -nowinkill -nopn -silent-dup-error Single application: -multiwindow -notrayicon -clipboard \ -keyhook -nowinkill -nopn -silent-dup-error Whole display: -nodecoration -notrayicon -clipboard -keyhook \ -nopn -silent-dup-error -screen 0 @ My x2goclient session is configured as: **Session preferences: Input/Output** [ ] Fullscreen [ ] Custom Width (greyed out 3696) Height (greyed out 2160) [X] Use whole display [ ] Maximum available Display: 2 When I start a new x2Go session, it correctly runs the X-Server with the "Whole display" command (as per Windows Task Manager): "C:\Program Files (x86)\x2goclient\VcXsrv\vcxsrv.exe" \ -nodecoration -notrayicon -clipboard -keyhook -nowinkill \ -nopn -silent-dup-error screen 0 @2 :0 But if I then "pause" this session and reconnect, x2goclient uses the "Window mode" command line options instead: "C:\Program Files (x86)\x2goclient\VcXsrv\vcxsrv.exe" \ -screen 3696x2160 -notrayicon -clipboard -keyhook \ -nowinkill -nopn -silent-dup-error :0 I suspect this has something to do with the code around line 4442 in onmainwindow.cpp, but I've not been able to figure out the exact details yet.

Bug#1510: nx defaults for packing are always overridden
by Ulrich Sibiller 01 Dec '20

Package: x2goclient Version: 4.1.2.2 NX has built-in defaults for the image compression parameter which are based on the selected connection speed. x2goclient does not honor these defaults but always sets the compression method explicitly. This means users who want to improve their performance by lowering the link speed setting (e.g. from wan to adsl) will not get the image compression nx thinks is best for the link speed but the one that is pre-defined by x2goclient, which is always 16m-jpeg-9. So they will not benefit from the best performance. See https://github.com/ArcticaProject/nx-libs/issues/802 for a description of the defaults: ----------------------------------------------- There are some high level compression modes, too, that will map to one from the list above: - "lossy" will map to "16m-jpeg" - "lossless" will map to "16m-rle-9" for link=lan and "16m-bitmap" for all other link types. - "adaptive" will choose lossy or lossless, depending on the characteristics of the image If no pack method is provided it will be set automatically from the link parameter: - modem: adaptive-3 - isdn: adaptive-5 - adsl: adaptive-7 - wan: adaptive-9 - lan: adaptive-9 -----------------------------------------------

Bug#1509: Unsupported pack methods
by Ulrich Sibiller 01 Dec '20

01 Dec '20

Package: x2goclient Version: 4.1.2.2 In the session configuration users can choose compressions methods with "rdp" and "rfb" in the name. Both compression methods are not supported by nx-libs since version 3.0.x and will lead to no image packing being used at all. From the session log: ... Loop: PANIC! Can't identify pack method for string '16m-rdp-compressed'. Error: Can't identify pack method for string '16m-rdp-compressed' ... Info: Using pack method 'none' with session 'unix-kde-depth_32'. ... This is absolutely counter-intuitive. Users selecting a compression method on purpose surely do not want to end up with no image compression at all. So they should be dropped completely.

Bug#1508: non Latin 1 passwords are rejected
by Sylvain Cuaz 27 Nov '20

27 Nov '20

Package: x2goclient Version: 4.1.2.2 Passwords with accents are rejected by x2goclient while working fine directly with ssh. Client OS Ubuntu 20.04.1 LTS with libssh 0.9.3-2ubuntu2.1 Server OS Ubuntu 16.04.6 LTS According to the documentation of ssh_userauth_password(), passwords should be passed as UTF-8. But sshmasterconnection.cpp passes auth_password.toLatin1(). I think just changing to auth_password.toUtf8() should suffice. Same thing goes for ssh_userauth_kbdint_setanswer() and maybe other calls. https://api.libssh.org/stable/group__libssh__auth.html#ga50c0c150f8c4703e7e… https://api.libssh.org/stable/group__libssh__auth.html#ga75e44b1f27059a0008…

Bug#1502: macOS X2GoClient keyboard map updates crash specific server applications, spike server CPU usage
by Yearke, Thomas 03 Nov '20

03 Nov '20

Package: x2goclient Version: 4.1.2.2 Tag: patch When the macOS version of X2GoClient is connected to a server, it updates the session's keyboard map every 10 seconds. Depending on how other programs running on the server respond to keyboard map changes, the repeated updates can cause brief CPU usage spikes or (in the case of one of our applications) they can cause freezes and crashes. The attached patch modifies the macOS client to only run the keyboard map update once on session startup. Testing done on my devices showed that this change resolved the issue without introducing noticeable side effects. However, I was not able to find the reason why the keyboard map is being updated regularly, so this may (re)introduce a problem I'm not aware of. Client OS: macOS 10.14.6 Client Software: X2GoClient 4.1.2.2 Server OS: CentOS 7.8 Server Desktop Environment: XFCE 4 Server x2goserver Version: 4.1.0.3 Server x2goserver-xsession Version: 4.1.0.3 Server nxagent Version: 3.5.99.24 Thank you for your consideration!

Additional image compression algoritms?
by Pär Larsson 26 Oct '20

26 Oct '20

Hi! Thanks for creating x2go, I'm a big fan! In the image compression field there has been progress during recent years. Would there be a point to implementing something like jpeg xl in X2Go? As I understand, it compares favorably to standard jpeg and png in every aspect. But perhaps it would not make a big difference or be difficult? Best, Pär Larsson, Sweden

x2goclient ssh password rejected
by Ian Malone 22 Oct '20

22 Oct '20

Hi, After a password change I found the following being rejected by x2go, logs on the host machine just showed the password failing. This was an AD password (now changed!) and direct access with plain ssh to the same host and other contexts in which it was used worked, only x2go seemed not to handle it (so I'm confident it wasn't being entered wrongly): baggl0beBottlesp£aker I get the "Authentication failed" "Access denied for 'password'. Authentication that can continue: publickey,gssapi-keyex,gss-with-mic,password" error popup. I've found an old unresolved bug report that suggests the £ character may be the problem, the reporter attached a patch which suggests changes from QString::toAsci to QString::toUtf8 in a number of places. https://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=926 looking at git some of these lines are currently using toLatin1 https://code.x2go.org/gitweb?p=x2goclient.git;a=blob;f=src/sshmasterconnect… which I'd have thought would be okay with £, so possibly something else is wrong (too long?). Another from around the same time relates to using cyrillic characters in passwords https://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=754 Client is x2goclient-4.1.2.2-1.fc30.x86_64 (Linux, Fedora 30) Host is x2goserver-common-4.1.0.3-3.el7.noarch x2goserver-4.1.0.3-3.el7.x86_64 (Linux, RHEL 7) Although I also tried an older host. /var/log/secure on the host looks like this (with names and IPs obfuscated): Oct 21 11:35:17 XXX sshd[6207]: pam_sss(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=XXX user=XXX Oct 21 11:35:17 XXX sshd[6207]: pam_sss(sshd:auth): received for user XXX: 17 (Failure setting user credentials) Oct 21 11:35:19 XXX sshd[6207]: Failed password for XXX from x.x.x.x port 45216 ssh2 Oct 21 11:35:19 XXX sshd[6207]: Received disconnect from x.x.x.x port 45216:11: Bye Bye [preauth] Oct 21 11:35:19 XXX sshd[6207]: Disconnected from x.x.x.x port 45216 [preauth] -- imalone

Bug#1500: Wishlist Bug: look for Branding-/Background-SVGs in well-known locations
by Stefan Baur 15 Oct '20

15 Oct '20

package: x2goclient priority: wishlist At the moment, X2GoClient has two SVGs "baked in", namely the ones for the background image and the branding in the lower left corner. These can be overridden with command line parameters. I would suggest a folder /usr/share/x2goclient/logos on Linux/macOS, and <programsdir>\x2goclient\logos on Windows, where these SVGs are placed instead. On Linux, /etc/x2goclient/logos should be a symlink to /usr/share/x2goclient/logos. On Client startup, it would then scan /etc/x2goclient/logos (or <programsdir>\x2goclient\logos) for these files, and use them. That way, swapping out these logos does not require adding --background or --branding to the call - on Windows, you would simply overwrite them with the logos of your choice, on Linux/macOS, you would replace the symlink with an actual directory and place your custom logos there - just like we do it for /etc/x2go/applications on the server. The command line parameters should remain in the code to support legacy installations. It MAY make sense to keep a minimum set of logos "baked in" (maybe a black on white "ERROR" text) to indicate when the file-based ones could not be found.

Gazebo 11 on Fedora 32 high CPU utilization via X2Go
by Robert Kudyba 26 Sep '20

Not sure if this is the best place to report this. Is this a X2Go issue, or a Gazebo issue with the Fedora package, or just a straight up Gazebo issue? Gazebo, gzclient, pins the CPU.

Bug#1493: Fullscreen client gets minimized when switching virtual desktops on Windows 10
by Tyler Anderson 06 Sep '20

06 Sep '20

Package: x2go-client Version: 4.1.2.2 I am using the x2go client in full-screen mode on one of my virtual desktops on windows 10. I can swipe through my virtual desktops with a four-fingered swipe on the trackpad or by pressing Win+ctrl+left/right. When I have the client in fullscreen, if I swipe to a different desktop and then back to the desktop containing the client, it has become minimized. It does not maintain its full-screen mode when switching virtual desktops. The same also occurs if I enter task view with a four-finger swipe up, the window is minimized when I return.

03 Sep '20

Hi All, I recently upgraded my x2go client from version 4.1.2.0 (Qt - 4.8.6) to 4.1.2.2 (Qt - 4.8.6). When I try to connect to one of my servers running CentOS 6 with the latest updates, my x2go client on Windows 7 x64 SP1 immediately crashes. In fact, the connection never even makes it to the remote server for processing according to the logs on the remote server, as the client forces the connection closed (due to it crashing). I even installed the debug version of the x2go client, and it doesn't output anything of value before it crashes either. Plus, it doesn't appear to log anything to a file either? After installing the old version of x2go in a different directory than the newest version, I am able to connect just fine to the server using the old x2go client version. Something broke from the update. What I can tell you is that I get this error message when debugging the crash through Visual Studio: https://serv1.dragndropz.com/user_images/2020_09_03/2256_oERSXY_2020-09-031… Also, I was able to replicate this issue in a virtualized instance of Windows 7 x64 SP1 via VirtualBox. The CentOS 6 server I'm trying to connect to isn't running anything special. However, it is one of my oldest servers, and as a result, it is the only server that is still running GNOME (usually I use MATE or XFCE). I'm using a non-standard ssh port, a private key that uses a passphrase, and "Session type" is set to GNOME. I've disabled sound support and client side printing support to make sure the crash didn't have anything to do with these features. Any chance someone could look into this further? For now, I will just run both versions of x2go side-by-side. Thanks OwN

Bug#1476: x2goclient interface code needs refactoring to make it more accessible and make improvements easier to implement and test
by Dave Chamberlin-Kidd 03 Sep '20

03 Sep '20

Package: x2goclient Version: 4.1.2.3 Severity: wishlist Tag: patch There are a number of minor issues, oddities and limitations with the current x2goclient gui which would be good to fix, resolve and improve on. Like all projects however the core team have more important issues to resolve. The code in its current state is difficult to understand and amend and as it has no tests it is risky for developers to make functional changes unless they spend a lot of time getting to know the code and doing extensive manual testing. Attached are 10 small refactorings which start extracting out some of the code into smaller functions. As the code is separated out it becomes easier to understand and change. There are no functional changes in these patches, nor do they attempt or claim to fix any known issues. On their own the benefit of these patches is limited however the hope is that over time I will be able to submit more refactorings as I learn more and then start fixing issues and improving the UI. Extracting out functions is just one of many techniques that can be used to make code cleaner but in my experience it's a good one to start with. It should also be noted that sometimes code is extracted "as is" even when it is clear further refactoring can be done to improve things, this is by design in order to keep risk and size of patches to a minimum. Cheers Dave

Bug#1492: Package: Multiple monitors / Xinerama crashes
by John Watson 02 Sep '20

02 Sep '20

Package: x2goserver-xsession Version: 4.1.0.3-5 NOTE: this is CentOS8's epel8.playground.noarch package Remove server environment: OS: CentOS 8 - 8.1.1911 (Core) x2goserver-xsession: x2goserver-xsession-4.1.0.3-5.epel8.playground.noarch nx-libs: nx-libs-3.5.99.23-1.epel8.playground.x86_64 Local server environment: OS: MacOS Catalina 10.15.6 x2go: X2Go Client v. 4.1.2.2 (Qt -4.8.7) When I invoke `xterm` or any other X11 app over x2go client on the laptop alone (not connected to any external monitors), everything works without any hiccups. With multiple monitors connected, however, an existing session will only render a blank screen locally, and the mouse pointer will disappear. When *creating* a new session, the remote server process crashes with the following in /var/log/messages (CentOS equivalent of /var/log/syslog) Aug 30 14:08:39 <server host> kernel: [62624.705481] x2goagent[2960736]: segfault at 0 ip 0000000000000000 sp 00007ffd426f92e8 error 14 in nxagent[5655328cb000+437000] This looks strikingly similar to the bug described in https://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=943, but it's now 2020 and I'm on the latest yum repo available to CentOS 8... I've added "+xinerama" to X2GO_NXAGENT_DEFAULT_OPTIONS in /etc/x2go/x2goagent.options and enabled it in the x2go client as well. Should I attempt playing with building nx-libs from source myself and installing?

x2goclient resumes session with wrong X-Server options
by Maarten Boekhold 02 Sep '20

02 Sep '20

Hi all, (I tried to sent this twice to x2go-user, but after more than 24 hours it still hasn't shown up there) Windows 10, x2goclient 4.1.2.2 When resuming a "paused" x2Go session, x2goclient is using the wrong X-Server settings. I have configured my x2goclient with the following settings for X.Org Server settings: **X.Org Server settings** [X] use custom X-Server Executable: C:/Program Files (x86)/x2goclient/VcXsrv/vcxsrv.exe [ ] start X-Server on X2Go Client start Window mode: -screen 0 %wx%h -notrayicon -clipboard -keyhook \ -nowinkill -nopn -silent-dup-error Fullscreen mode: -fullscreen -notrayicon -clipboard -keyhook \ -nowinkill -nopn -silent-dup-error Single application: -multiwindow -notrayicon -clipboard \ -keyhook -nowinkill -nopn -silent-dup-error Whole display: -nodecoration -notrayicon -clipboard -keyhook \ -nopn -silent-dup-error -screen 0 @ My x2goclient session is configured as: **Session preferences: Input/Output** [ ] Fullscreen [ ] Custom Width (greyed out 3696) Height (greyed out 2160) [X] Use whole display [ ] Maximum available Display: 2 When I start a new x2Go session, it correctly runs the X-Server with the "Whole display" command: "C:\Program Files (x86)\x2goclient\VcXsrv\vcxsrv.exe" \ -nodecoration -notrayicon -clipboard -keyhook -nowinkill \ -nopn -silent-dup-error screen 0 @2 :0 But if I then "pause" this session and reconnect, x2goclient uses the "Window mode" command line options instead: "C:\Program Files (x86)\x2goclient\VcXsrv\vcxsrv.exe" \ -screen 3696x2160 -notrayicon -clipboard -keyhook \ -nowinkill -nopn -silent-dup-error :0 This is really annoying. I suspect this has something to do with the code around line 4442 in onmainwindow.cpp, but I've not been able to figure out the exact details yet. I've tried to debug this by running x2goclient.debug.exe --debug, but there's an issue here. When running the debug version, the "Use whole display" option is not available in the session settings tab: **Session Input/Output with x2goclient.debug.exe --debug** [ ] Fullscreen [ ] Custom Width (greyed out 3696) Height (greyed out 2160) [ ] Maximum available See the "Use whole display" option missing in front of the "Maximum available" radio box. It's almost as if the debug build included in this distribution is of an older x2goclient version (but it shows the correct version number in the About dialog). I hope that based on the provided information a fix can be created for this issue? Regards, Maarten

X2Go: The Gathering 2020 AKA V/RUS (2020-09-18 - 2020-09-20) will take place at Stuttgart's hackerspace "shackspace"
by Stefan Baur 18 Aug '20

18 Aug '20

Dear $ALL, As stated in the subject line, X2Go: The Gathering 2020 - AKA V/RUS, the Virtual/Remote User Symposium - will take place at Stuttgart's hackerspace "shackspace", from Friday afternoon, 2020-09-18, to Sunday afternoon/evening, 2020-09-20. X2Go: The Gathering is the annual event where users, admins, and developers (including the i18n volunteers) of X2Go meet face to face, to discuss current X2Go-related issues, fix open bugs, and have a good time getting to know each other. As there is some overlap between X2Go, Arctica, and orca e.V., you can expect to meet members of those groups as well. Due to the Covid-19 pandemic, this year's X2Go: The Gathering will be a hybrid event with minimal on-site participation. We will be live-streaming the event, probably via Jitsi or BigBlueButton, and most likely we will have a YouTube stream going on as well. Links to the streams will be posted on <http://wiki.x2go.org/doku.php/events:x2go-gathering-2020> each day before the stream begins. *ATTENTION!* If you're interested in joining us *physically*, please contact <mailto:X2Go-ML-1@baur-itcs.de> with the text "The Gathering" somewhere in the subject and bug me publicly on the X2Go-Project list if you don't receive a confirmation by e-mail after a day or two. We will not be providing accomodation this year (so if you cannot commute daily, you will have to look for a hotel/hostel room yourself), *but we still need your contact info* if you wish to take part in person, due to current Covid-19 health regulations. Also, you will be required to wear a non-medical everyday mask or comparable mouth and nose cover (of course, better masks like N95/KN95/FFP2/FFP3 are okay as well, as long as they do not have an exhalation valve), both when using public transport (and while waiting at the platforms/stops), as well as inside shackspace (you will likely be allowed to take the mask off while sitting at your desk, but we cannot guarantee that yet). For joining us *virtually*, you can join in any time, even on short notice, no sign-up required (it would still be nice if you'd let us know in advance, so we can make sure we have sufficient server and streaming capacity). We will be updating the Wiki page <http://wiki.x2go.org/doku.php/events:x2go-gathering-2020> as more information becomes available. As this year's event is a hybrid event with minimal on-site participation, there is not really a need for event sponsorships. However, if you're a company that had planned to sponsor the event, we'd appreciate it if you'd redirect the money to some paid work on X2Go instead. A list of companies/individuals available for this can be found here: <https://wiki.x2go.org/doku.php/doc:professional-support> CFD.direct, one of our long-time sponsors (<https://wiki.x2go.org/doku.php/doc:sponsors>), has already done so - and not only that, they have increased their funding from 700 EUR, as originally planned, to 1000 EUR, as you can read here: <https://wiki.x2go.org/doku.php/events:x2go-gathering-2020#sponsoring>. We will be pooling their sponsorship money with another donation by KLO Ingeniería Informática, so we will have 1100 EUR at our disposal. This money will be used to try to tackle the long-standing clipboard issues in the NX-libraries. If you want to add money into that pool, or want to sponsor other X2Go-related work, again, please see the above list of companies/individuals available for such work. Sincerely, Stefan Baur, "X2Go: The Gathering" event organizer -- 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
