Failed messages during startup & small session menu
by Olaf 20 Dec '21

20 Dec '21

Hi! The start process from the boot menu to the session menu takes an extremely long time, several minutes. The three graphic points in the middle on a black background suddenly become confusing characters, then comes: Starting User Login Management... [ OK ] Finished Hold until boot process finished up. [ OK ] Finished Terminate Plymouth Boot Screen. [FAILED] Failed to start User Login Management. See 'systemctl status systemd-logind.service' for details. [FAILED] Failed to start User Login Management. [FAILED] Failed to start Load Kernel Module drm. [FAILED] Failed to start User Login Management. [FAILED] Failed to start Load Kernel Module drm. [FAILED] Failed to start User Login Management. After that Debian GNU/Linux 11 x2gothinclient tty1 x2gothinclient login: After that ultimately, the session menu appears graphically correct in the upper left corner, but much too small, as if the screen size was not recognized. Or is there somewhere a setting option for the size? If you select a session, the session will be opened correctly in full screen. The termination (shutdown) of the session also takes a lot of time, until the small session menu. What can be the reason? Greetings, Olaf (Tested in the preview window of vmware esxi client and locally with a real client.)

pxe-boot: unable to locate configuration file
by Olaf 19 Dec '21

19 Dec '21

Hello! I have set up a new server with an Ubuntu offshoot (bodhi). The client reports correct IP / Mask / DHCP IP / Gateway IP from dhcpd.conf when booting via pxe, but then: "PXELINUX 6.04 PXE 20191223 ... Anvin ... Unable to locate configuration file" /etc/dhcpd.conf: next-server 192.168.3.8; filename "/pxelinux.0"; interface ens160; Connecting from another PC with x2go client works. I've been sitting there for hours and can't get any further. Would be great if someone could help me. /etc/default/isc-dhcp-server: INTERFACESv4 = "ens160" /etc/exports: /opt/x2gothinclient/chroot 192.168.3.0/255.255.255.0(ro,async,no_root_squash,no_subtree_check) /srv/tftp/pxelinux.0 => /usr/lib/PXELINUX/pxelinux.0 Greetings, Olaf

X2Go: The Gathering 2021 AKA "Over 9000!" (2021-12-03 - 2021-12-04) will be an entirely virtual event
by Stefan Baur 01 Dec '21

01 Dec '21

Dear $ALL, As stated in the subject line, X2Go: The Gathering 2021 - AKA "Over 9000!" - will be an entirely virtual event and will take place from Friday afternoon, 2021-12-03, to Sunday afternoon/evening, 2021-12-05. If you're wondering what the “Over 9000!” is about, take a look at <https://en.wikipedia.org/wiki/It%27s_Over_9000!> and at <https://experience.arcgis.com/experience/478220a4c454480e823b17327b2bf1d4>, especially the box titled “COVID-19-Fälle” (active Covid-19 cases), which is way over 9000. Under normal conditions, X2Go: The Gathering would be the annual event where users, admins, and developers (including the i18n volunteers) of X2Go, as well as members from the Arctica project and the orca e.V. nonprofit meet face to face, to discuss current X2Go-related issues, fix open bugs, and have a good time getting to know each other. Sadly, due to the ongoing Covid-19 pandemic, this year's X2Go: The Gathering will have to remain entirely virtual. Due to various reasons, we were unable to schedule the event earlier in the year, where Covid-19 infection numbers were lower and where meeting outside or keeping the windows open all day might have worked, so we're stuck with this late event date, which sadly coincides with the fourth Covid-19 wave here in Germany. This means we will be meeting via Jitsi and we will be live-streaming the event via YouTube. Links to the streams will be posted on <http://wiki.x2go.org/doku.php/events:x2go-gathering-2021> each day before the stream begins. You can join in any time, even on short notice, no sign-up required. We will be updating the Wiki page <http://wiki.x2go.org/doku.php/events:x2go-gathering-2021> as more information becomes available - especially the schedule, which is currently still in the works. We plan to release (at least) three new features for X2Go at or at least shortly after this year's X2Go: The Gathering, namely: - the HTML5 client - server-side X2Go-KDrive support, and - X2Go support in Remmina. The former two are currently already available via nightly builds, but we intend to declare them stable and turn them into a proper release. The latter should become available with the next Remmina release. Also, we intend to present the current state of X2Go-TCE on the Raspberry Pi. If time permits (and the individuals required for this are available for it), we will also attempt to move our bugtracker and git to our own gitlab instance (at least for new bugs). As this year's event is an entirely virtual event, 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> If you're not sure what to sponsor - while the features already mentioned above are ready to be included in a stable release, they could still use some more love and affection. For example: - The HTML5 and Remmina clients don't support file and printer sharing yet - The HTML5 client also lacks sound support - The HTML5 client only works with KDrive, not "classic" X2Go-NX (to be honest, NX inside HTML5 doesn't really make sense since we are about to release KDrive as stable, but if you feel you have a good reason for it, let us know ...) - Remmina only works with "classic" X2Go-NX, not KDrive, and only on a client that still supports X11 (even though Remmina in general also works on a Wayland-only client) -> KDrive support would require a shared library for KDrive, either written in GTK or with more low level rendering toolskits (e.g. Glib-2.0 and Cairo, etc.). - KDrive probably needs some more work on the Windows (and possibly macOS) Client side. - X2Go-TCE on the Pi, while functional in general, still has some untested areas and is a little rough around the edges. - Also, we have been contacted once again regarding USB forwarding support in X2Go, so anyone interested in co-sponsoring this feature should speak up or at least contact me off-list - maybe we can get a co-sponsoring going, lowering the cost for all parties involved. And of course, you can also make donations, either in general or specifically earmarked for X2Go, via orca e.V. The entire schedule, save for the time and date of the orca e.V. meeting on Sunday, is still in a state of flux. We may move some presentations to a Saturday slot, depending on the availability of the speakers involved. If you would like to present something, please contact me via E-Mail (<mailto:X2Go-ML-1@baur-itcs.de>) and let me know the title of your presentation/talk, the expected duration and the times you would be available. Of course, you can also pre-record your presentation/talk if you want, but you will have to upload it to YouTube yourself and let us know the link (it may be unlisted, but must not be marked "private"). Sincerely, Stefan Baur, "X2Go: The Gathering" event organizer PS: Please heed the "reply-to" when replying, and make sure your reply gets sent only to <mailto:x2go-ml-1@baur-itcs.de>, as this message is sent to multiple X2Go mailing lists at once (and it is likely you are not subscribed to all of them, so your replies would clog up the moderation queue for the others). -- 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

Stop pxe-Server
by Olaf Staubus 01 Dec '21

01 Dec '21

Hello! How can I stop the pxe-server (only the pxe function)? I have installed a new Linux server with x2go and would like to test this parallel to the old Linux x2go server, but the new one does not accept the old pxe server. Since at that time I installed the x2go server and the pxe server together on one, I only want to be able to stop / start the pxe-function of the old one to test the new one. Would be great if someone can help. Greetings, Olaf

Dear All, I am new to X2go and to this emailing list. I have used it successfully for a couple of weeks. Then, once, I got the following error message while attempting login (windows10): Failed to start X2Go Agent session with ID xxxxxxx. X2Go Agent terminated unexpectedly. Aborting session startup. I tried to 1. restart PC 2. unistall-reinstall 3. delete session-recreate session 4. exit putty-re-entering I have no more attempts to do. I have used other clients before, and for one of those this sometimes would happen. What I was doing was to -kill geometry in putty and then re-do one. Is there something similar I can do here? I tried to visualize the Archive of this mailing list but I could not find a way to search previous posts. I am lost. Any help would be highly appreciated. Thanks!!!

Hello, I'm trying to repair the packaging of x2go in Mageia. It was functional in Mageia 7, but this is no more the case in Mageia 8 or cauldron (development version). I have tried 2 clients: x2goclient 4.1.2.2 and pyhoca-gui 0.6.1.1 packaged for Mageia 8. For the server, in a virtualbox VM, I tried to install the master version of x2goserver; through make && make install. I had to change the rights to add write credential on /var/lib/x2go and /var/lib/x2go/x2go_session I use also nxagent-3.5.99.25-1.mga8 and nxproxy-3.5.99.25-1.mga8 packaged for Mageia 8. Thus I have linked xgoagent to /usr/lib64/nx/bin/nxagent Using pyhoca, I can establish the session with the VM, either with the main user or with a test user, using password. But when I try to launch the desktop or a single application like Terminal, this fails. In the journal of the server, i get: sshd[96864]: Accepted password for test from 192.168.1.14 port 35740 ssh2 systemd-logind[683]: [🡕] New session c25 of user test. systemd[1]: Started Session c25 of user test. sshd[96864]: pam_unix(sshd:session): session opened for user test by (uid=0) /usr/local/bin/x2gostartagent[97691]: successfully started X2Go Agent session with ID test-93-1636213441_stDLXQt_dp24 sshd[96871]: error: connect_to 127.0.0.1 port 51346: failed. sshd[96871]: error: connect_to 127.0.0.1 port 51346: failed.

I don't understand what goes wrong and what to do to debug or restore the normal behavior.

X2Go server on Fedora 35 KDE
by Michael Eager 08 Nov '21

08 Nov '21

When I try to connect to a F35 LXD VM using x2goclient, I get an error "Cannot Exec startkde". This can be fixed by either running "sudo ln -s /usr/bin/startplasma-x11 /usr/bin/startkde" in the VM or changing the command in x2goclient. When a screen is displayed, it is completely black, with an arrow cursor. I've seen a couple bug reports about black screen, but none seem to be relevant. -- Michael Eager

X2Go on openSUSE
by Peter Keller 08 Nov '21

08 Nov '21

Dear list, The instructions for installing X2Go on openSUSE systems on the wiki page at <https://wiki.x2go.org/doku.php/wiki:repositories:suse> seem very outdated. The X2Go repositories only provide binaries up to openSUSE 15.1. These still worked on 15.2 in my hands, but at the current openSUSE release (15.3) support for Qt4 has been dropped and the X2Go repository binaries will no longer work on this distribution (unless it has been upgraded from 15.2, and the Qt4 libraries retained). The correct location for X2Go on SUSE systems now seems to be https://download.opensuse.org/repositories/X11:/RemoteDesktop:/x2go/<distro-version>/ as mentioned in this forum thread: <https://forums.opensuse.org/showthread.php/555520-x2go-client-shared-librar…>. Perhaps someone with write access to the wiki could update the SUSE page? Regards, P.

X11 fonts
by Michael Eager 04 Nov '21

04 Nov '21

I have been trying to run a legacy Motif application on a Fedora 33 VM, connecting using X2Go. With respect to using X11 core fonts, the Motif app works like the X11 xfontsel application. Connecting to the VM using X2Go, I tried to install the liberation fonts, but was unsuccessful. I installed them system-wide and in a local .fonts directory, but xfontsel did not see them. I updated the font search path to include the liberation fonts directory using "xset -fp", and this appeared to work ("xset q" showed the updated path), running "fc-cache" would list the liberation font directories, but xfontsel did not see the fonts. It appeared that running "fc-cache" reset the font search directory to the default, without the liberation fonts. I found a comment that with X2Go fonts need to be installed on both the client and server. The liberation fonts are on both. When I connect to the VM using "ssh -X" or "vncviewer" I am able to install X11 fonts and xfontsel shows them. (And the legacy Motif application sees them as well.) Can anyone tell me how to install fonts so that applications running under X2Go will see them? -- Michael Eager

How to reduce fonts size?
by nicolas.x2go＠ecarnot.net 28 Oct '21

28 Oct '21

Hello, Though I read https://www.mail-archive.com/x2go-user@lists.x2go.org/msg03049.html and when using 'Single application' or 'Published applications', and running Thunderbird (91.1.2) from a 4.1.0.3-5 x2go server running on an Ubuntu 21.10, to my XUbuntu 21.10 desktop, whatever setting I'm trying to use about the DPI has absolutely no effect on the fonts size in the published Thunderbird. They are significantly bigger, and don't change either when raising nor lowering the DPI setting. Is this something I could check somewhere in the logs, or does anyone has any advice about it? Thank you. -- Nicolas

x2goagent segfaulting on client connect
by Eric Shell 25 Oct '21

25 Oct '21

I have a CentOS 7.9 system on which X2Go was previously working perfectly, but which is now broken. It broke after a typical yum update but I am not sure what changed to break things and I would like some help debugging and resolving this issue. I should mention that as part of my troubleshooting I have begun using NVIDIA kmod drivers from the ELRepo instead of ones installed from NVIDIA's .run file. The behavior I'm seeing in every failed connection produces the following log entries. The system has both XFCE and MATE installed and both produce the same output. - Oct 19 10:21:29 c113256 /usr/bin/x2goruncommand: launching session with Xsession-x2go mechanism, using STARTUP="mate-session" Oct 19 10:21:29 c113256 /usr/bin/x2goruncommand: dbus wrapper available as /usr/bin/dbus-run-session Oct 19 10:21:30 c113256 kernel: resource sanity check: requesting [mem 0x000c0000-0x000fffff], which spans more than PCI Bus 0000:00 [mem 0x000c4000-0x000c7fff window] Oct 19 10:21:30 c113256 kernel: caller os_map_kernel_space.part.6+0x95/0xc0 [nvidia] mapping multiple BARs Oct 19 10:21:31 c113256 kernel: x2goagent[58376]: segfault at 48 ip 0000555fbee349ab sp 00007ffe380702a0 error 4 in nxagent[555fbecd6000+439000] Oct 19 10:21:31 c113256 abrt-hook-ccpp: Process 58376 (nxagent) of user 1001 killed by SIGSEGV - dumping core - Interestingly, x2goagent does not segfault if I have the X2Go client run /bin/xclock.

Programs opening on wrong xserver

Hi all I'm having an issue where some apps open on the wrong screen. If I'm logged in locally on the physical machine, then log in via x2go, and start some software it opens (or tries to) on the physical display on the locally logged in account. I sshed in and made a new user, then connected via x2go and saw no issues. Has anyone seen behaviour like this before? It's very strange, and didn't happen before I upgraded to Ubuntu 21.10. Jake

I'm new to the mailing list and long time user of X2Go on the same HP Notebook. Windows 10. X2go is running over Pulse Secure as the VPN to a Remote Server. When starting X2go on my notebook there is no message other than an Application Event Log Error. Faulting application name: x2goclient.exe, version: 0.0.0.0, time stamp: 0x057066f0 Faulting module name: ntdll.dll, version: 10.0.19041.1202, time stamp: 0xef8beaeb Exception code: 0xc0000005 Fault offset: 0x00087470 Faulting process id: 0x378c Faulting application start time: 0x01d7ba7ea3b2ccb2 Faulting application path: C:\Program Files (x86)\x2goclient\x2goclient.exe Faulting module path: C:\Windows\SYSTEM32\ntdll.dll Report Id: 515a0295-b6ef-4134-804b-6b7f245dda43 I've tried removing and reinstalling X2Go without any change. I had a look for an X2Go Log file or dump that might give me a further lead to follow. I've attached that to the email. I also Had a look at the properties of the ntdll.dll That shows a fresh version - so that may be a pointer. Are there special compatibilities to be aware of ? Would be grateful for suggestions where next to look. Thanks Peter

Speed up inital x2go connection - takes about 10 sec to connect
by Alexander Baader 05 Oct '21

05 Oct '21

Hi all, I installed the latest x2go windows client (on windows 10) and one x2go server on RHEL 8. I installed all necessary packages from RHEL and EPEL Repos and generally it’s working fine. I use ssh keys for password less authentification. All is currently on the same lan, no wan or something like this. It disabled sound, file sharing, printing and all on the x2go client (serverside all is default) and launch a single application .. firefox. When I click on the x2go Icon to start the connection, the client shows „connecting“ („Verbinde“ on german) and nothing happens inside the details log panel. After about 10 sec. a lot of messages are appearing and firefox starts in about 1 sec. Is there any possibilty to improve the inital connection? If I connect via putty all is fast without any delays. I searched a while the archive and just found this post: https://lists.x2go.org/pipermail/x2go-user/2020-October/006319.html <https://lists.x2go.org/pipermail/x2go-user/2020-October/006319.html> My nxagent is higher then the mentioned version: # dnf list | grep nxagent nxagent.x86_64 3.5.99.26-1.el8 @epel Are there any further possibilties? Thanks a lot! Regards Alex

Expedite Windows x2go client close on loss of connection?
by James Bowery 23 Sep '21

23 Sep '21

I frequently encounter connection interruptions. Each such interruption results in the x2go client freezing for about a minute before the notification window pops up to ask if I want to terminate the session or not. Upon confirming, it then takes another minute before the x2go window closes. Is there any way grab the x2go client by the scruff of the neck and make it go away the moment I notice it isn't responding to keypresses?

desktop sharing: would like to share (groups of) windows
by Jos Huisken 14 Sep '21

14 Sep '21

I'm a new user and trying to share a session on different machines/displays. So, on the server I start a session, say DISPLAY=:50 from a client with a regular 1960x1280 screen. When I move to another machine/display, for instance using a 4K screen, I can share the desktop. I'm getting a 1960x1280 desktop with the windows on :50. That's not really what I want. Instead, I would like to get all :50 windows -without- having a special window for the desktop. Ideally I would like to move the windows :50 independently of the original session. Since, on the 4K screen, I prefer a different placement of windows. Ideally I would like to share a group of windows belonging to one part of the process-tree. Essentially this means that window positions should become client specific. Is something like this possible at all? Please note I'm not subscribed on this mailing list, I will watch the mail-archive now and then. P.S. desktop sharing leaves echoes of a moved window in the desktop, this is a bug I guess

Black screen with Fedora 34 KDE
by Michael Eager 09 Sep '21

09 Sep '21

I've created an LXD container with Fedora 34 and KDE. When I connect using x2go, I initially see a login screen (SDDM, I believe). After I log in, all I see is a black screen. No menu bars, no cursor. There's nothing interesting in the system log, but a .xsession-errors file was generated. There's an XIO error: $ cat .xsession-x2go-fedora34-errors XSession-x2go: X session started for eager at Sat Sep 4 18:59:28 UTC 2021 xsettingsd: Loaded 0 settings from /home/eager/.config/xsettingsd/xsettingsd.conf xsettingsd: Created window 0xe00001 on screen 0 with timestamp 2989364519 xsettingsd: Selection _XSETTINGS_S0 is owned by 0x0 xsettingsd: Took ownership of selection _XSETTINGS_S0 xsettingsd: Reloading configuration xsettingsd: Loaded 10 settings from /home/eager/.config/xsettingsd/xsettingsd.conf xsettingsd: Reloading configuration xsettingsd: Loaded 10 settings from /home/eager/.config/xsettingsd/xsettingsd.conf xsettingsd: Reloading configuration xsettingsd: Loaded 10 settings from /home/eager/.config/xsettingsd/xsettingsd.conf xsettingsd: Reloading configuration xsettingsd: Loaded 10 settings from /home/eager/.config/xsettingsd/xsettingsd.conf xsettingsd: Reloading configuration xsettingsd: Loaded 10 settings from /home/eager/.config/xsettingsd/xsettingsd.conf xsettingsd: Reloading configuration xsettingsd: Loaded 10 settings from /home/eager/.config/xsettingsd/xsettingsd.conf xsettingsd: Reloading configuration xsettingsd: Loaded 10 settings from /home/eager/.config/xsettingsd/xsettingsd.conf xsettingsd: Reloading configuration xsettingsd: Loaded 10 settings from /home/eager/.config/xsettingsd/xsettingsd.conf xsettingsd: Reloading configuration xsettingsd: Loaded 10 settings from /home/eager/.config/xsettingsd/xsettingsd.conf vmware-user: could not open /proc/fs/vmblock/dev Error: /usr/bin/vmtoolsd must be run inside a virtual machine on a VMware hypervisor product.

x2go error after updating from Ubuntu 16.04 to 20.04
by Dr. Tobias Holzmann 09 Sep '21

09 Sep '21

Dear everybody, yesterday I updated a server which is used by my team using x2go. The Linux update (Ubuntu 16.04 to 20.04) went well and everything is up and running. x2go works fine too but opening e.g., graphic user interface programs such as blender, paraview, or salome/freecad. The error for e.g., paraview, is: qt.qpa.xcb: X server does not support XInput 2. And a lot of other error messages. However, locally everything works quite well and hence, it should be related to x2go. Probably a lot of info is missing to get into the problem. In any case, I will provide any information one needs. Thanks in advance for any support/hint. -- Glück Auf | Kind Regard Tobi

Re: [X2Go-User] Big problem with keyboard/layout
by webman＠manfbraun.de 06 Sep '21

06 Sep '21

Hello! Many thanks for your reply. I'll try to check that all out in the next days. I thought, "you are pretty sure" wrong and re-testet it immidiately - it is the same for xterm, like I remembered from older tests (to avoid issues with mate-/xfce-/konsole terms). Manfred ----- Original Message ----- From: Ulrich Sibiller [mailto:uli42@gmx.de] To: <webman(a)manfbraun.de> Cc: x2go-user(a)lists.x2go.org Sent: Sun, 5 Sep 2021 21:06:30 +0200 Subject: Re: [X2Go-User] Big problem with keyboard/layout This is most likely because your desktop environment (xfce) is setting the keyboard itself AFTER x2go does. x2go determines the keyboard using this or a similar command and passes the keyboard to the other side where it calls setxkbmap (there's also an option to let x2goagent do all this itself without setxkbmap, see man nxagent; but for this problem it will probably not help). If the desktop environment kicks it AFTER the x2go setting will be gone. You can check by running setxkbmap -query both INSIDE the session and locally. And you can fix it (temporarily) by running INSIDE the session "setxkbmap -model ... - layout ... -rules ... -variant ... -option ..." based on the values from your local setxkbmap. (leave out parameters your setxkbmap -query does not print). You can also run an test session where you just specify xterm as your "desktop environment". I am pretty sure the keyboard will be correct then. Can you confirm?
