Re: [X2Go-User] x2go-user Digest, Vol 119, Issue 3

Hi, I can't troubleshoot this issue. I have removed X2goclient from the Debian Stable (Bookworm) install, including all config, but when installing it fresh, it still does crash with a Segsev, is this bug known? I can't use X2go anymore on Linux, it just fails, without a way to find out what breaks. This issue has blocked me for many months now, it works on Windows, but most of my machines are running Linux. Anybody have an idea what I can try next?

ssh connection through bastion host
by Hauke Fath 27 Jun '24

27 Jun '24

Hi, I am trying to connect with the Mac x2goclient (v4.1.2.2) through a bastion host*, essentially as a version of the openssh '-J' option. My setup in ~/.ssh/config works for ssh, but it looks like the x2go client (libssh? Where is that in the source tree?) does not look at config. With an ssh proxy connection configured in x2go, I can see a login on the bastion host, but nothing on the target machine. And what logs x2go has are too quickly replaced by a user/passwd login screen to be readable. How can I have the x2go client log to a file?

How to change X2Go MaxClient setting?
by "Adrián Gibanel" 18 Jun '24

18 Jun '24

1) Maximum number of clients reached So, I'm one of those users that have a lot windows and applications open at the same time for a long period of time. So I reach very easily the default Xorg 256 limit and when I try to open a new Xorg program I get the following error: Maximum number of clients reached . As per a quick search in a local system with Xorg this would be fixed by adding a file changing this limit to either 64, 128, 256, 512, 1024 or 2048. Something like: printf 'Section "ServerFlags"\n\tOption "MaxClients" "512"\nEndSection\n' \ > /etc/X11/xorg.conf.d/99-maxclients.conf and then restarting the Xorg server. 2) X2Go - And Xorg conf files As I am using X2Go I know that I'm not dealing with the usual Xorg server but with an improved one based on older Xorg upstream releases. I was expecting to find an /etc/something/xorg.conf.d/ where I could create a similar .conf but I haven't found any of this. At least, not explicitly documented. If I'm being honest I'm not very sure if it's nxagent, nxproxy or x2agent the one process which it's an actual Xorg server. 3) How to change MaxClients for X2Go? So my question is: - Can I change MaxClients with a conf file or do I have to recompile some program/library ? - If so Where do I create that conf file? 4) X2Go / Library versions This is Debian 12 (Bookworm) using distro's own packages. I also have old .list file disabled. So that means that in the past I used the http://packages.x2go.org/debian repo. I haven't found out an official way of describing/documenting your installed software towards receiving free support here so hopefully this will do it, otherwise just ask whatever you need: dpkg -l | grep -E 'nx|x2go' ii libnx-x11-6:amd64 2:3.5.99.26-5+deb12u1 amd64 nxagent's libNX_X11 client-part library ii libx2go-config-perl 4.1.0.3-7+deb12u1 all Perl X2Go::Config package ii libx2go-log-perl 4.1.0.3-7+deb12u1 all Perl X2Go::Log package ii libx2go-server-db-perl 4.1.0.3-7+deb12u1 amd64 Perl X2Go::Server:DB package ii libx2go-server-perl 4.1.0.3-7+deb12u1 all Perl X2Go::Server package ii libx2go-utils-perl 4.1.0.3-7+deb12u1 all Perl X2Go::Utils package ii nx-x11-common 2:3.5.99.26-5+deb12u1 all nx-X11 (common files) ii nxagent 2:3.5.99.26-5+deb12u1 amd64 Nested Xserver (aka NX Agent) supporting the NX compression protocol ii nxproxy 2:3.5.99.26-5+deb12u1 amd64 NX proxy rc x2goagent 2:3.5.0.33-0x2go1+git20180205.776+9.saimaa.1 all X2Go agent ii x2goclient 4.1.2.2-2+b1 amd64 X2Go Client application (Qt5) ii x2gokdriveclient 0.0.0.1-1+b1 amd64 KDrive graphical client backend for X2Go Client ii x2goserver 4.1.0.3-7+deb12u1 amd64 X2Go Server ii x2goserver-common 4.1.0.3-7+deb12u1 all X2Go Server (common files) ii x2goserver-extensions 4.1.0.3-7+deb12u1 all X2Go Server (extension support) ii x2goserver-fmbindings 4.1.0.3-7+deb12u1 all X2Go Server (file manager bindings) ii x2goserver-printing 4.1.0.3-7+deb12u1 all X2Go Server (printing support) ii x2goserver-x2goagent 4.1.0.3-7+deb12u1 amd64 X2Go Server's X2Go Agent ii x2goserver-xsession 4.1.0.3-7+deb12u1 all X2Go Server (Xsession runner) 5) In case it matters: - I use x2goclient to connect to my own machine (server is localhost) - X2Client is opened in a local Xorg KDE Plasma session with one user - Once I'm inside X2Go I'm using a KDE Plasma with another different user Thank you very much! -- [ http://www.btactic.com/ ] Adrián Gibanel I.T.

X2Go: The Gathering 2024 (2024-06-28 to 2024-06-30) will take place at Linuxhotel, Essen, Germany
by Vorstand ORCA e.V. 23 May '24

23 May '24

Dear $ALL, As stated in the subject line, X2Go: The Gathering 2024 will take place at Linuxhotel, Essen, Germany, from Friday afternoon, 2024-06-28, to Sunday afternoon/evening, 2024-06-30 and will, again, be a three-day "work and play" (coding, chatting, sightseeing, socializing) event. 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 see members of those groups as well. After 4 years spent "in exile" (with a skeleton crew of volunteers meeting at shackspace in 2020, and going completely virtual in the years 2021-2023) due to the pandemic situation, we are finally returning to a full real-life event at Linuxhotel (though we will be streaming/recording our sessions, so you can join in remotely as well). Note that while we do not require masks to be worn, it is still recommended and endorsed, especially in indoor areas. At the time of writing this invitation, and using some educated guesses regarding under-reporting and wastewater analysis, Covid infection rate in Germany is roughly somewhere between 1 out of 1000 and 1 out of 500 people per week. *ATTENTION!* If you want to join us *and* want to sleep in one of the hotel rooms at the Linuxhotel, we need the number of beds and nights you want to reserve, as well as *your full name* (as printed on your passport) and *your nationality* by *2024-06-07* *23:59:59* *CEST*!!! Very important!!! After that date, we cannot guarantee that we will still be able to reserve a room for you! First come, first serve! As single rooms are in short supply, please book your bed in a 2- or 3-bed room, unless you absolutely have to use a single room. Please send your reservation request to <mailto:vorstand@orca-ev.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. If for some reason or other you do *not* need a place to sleep at Linuxhotel, but *do* want to join us, please *still* let us know in advance that you're planning to visit. There's no such hard deadline as for the room reservations, but you will need to "check in" (and there will be an "Admission fee") for our gathering with the Linuxhotel staff, so please *do* let us know in advance. We will be updating the Wiki page <http://wiki.x2go.org/doku.php/events:x2go-gathering-2024> as more information becomes available. We already have one sponsor for the event - CFD.direct have kindly offered to sponsor the Pizzas on Friday evening - but the more, the merrier, so if you know someone willing and able to co-sponsor the event, please let us know at <mailto:vorstand@orca-ev.de> as well. Whether they wish to send us some "swag" with their company branding, or pledge money that we can use to lower dining and lodging costs for our participants (or to lower their health risks by providing masks, sanitizers and free testing), their sponsorship is greatly appreciated. Sincerely, Stefan Baur, "X2Go: The Gathering" event organizer

x2go for wayland
by Neal Becker 29 Apr '24

29 Apr '24

I'm curious if there will be something like x2go for wayland. I've been playing with waypipe. It does appear to at least work for allowing a remote application running on wayland to be used on my local machine. Not sure if it performs as well on low-bandwidth connections as x2go using NX, but at least seems usable in some limited testing. What's missing is persistent sessions and remote desktop. While waypipe allows running a remote app, it doesn't AFAIK allow a remote desktop, nor persistence. A bit of googling found nothing useful. Anyone know if there is work in this area? Thanks, Neal

How to Pass SSH Options From X2goclient?
by Jon Forrest 29 Apr '24

29 Apr '24

Due to reasons too sad to describe, I need to X2go from a modern Fedora 40 system to a Ubuntu 10.04 (!) system. Running ssh from the command line fails with the message Unable to negotiate with XX.XX.XX.XX port 22: no matching host key type found. Their offer: ssh-rsa,ssh-dss After some work I got this to work by adding -oHostKeyAlgorithms=+ssh-rsa -oPubkeyAcceptedAlgorithms=+ssh-rsa to the ssh command line. My question is how can I add these options to the ssh command that X2go executes on the client? Cordially, Jon Forrest

Lots of artifacts with deb12 server
by E. N. 29 Apr '24

29 Apr '24

Hi all, getting a lot of artifacts on a machine I upgraded from deb11+x2go repos server packages to deb12+x2go distro packages. (v4.1.0.3-7). I though about going for x2go repos, but deb12/bookworm isn't mentioned, should I go for the x2go repos or stick to the deb packages? Client is Ubuntu 22.04LTS with v4.1.2.2 which has worked alright for various x2go servers so far. Server hardware changed, too, before was Ryzen 3000, now is intel N100 in case that matters. Connection settings are LAN plus default compression method 16m-jpeg, tried 2m-jpeg, too. (Too many options btw or too little explanation on differences) Appreciate any advice.

Mounting USB drives in remote computer
by Kalle Tuulos 20 Apr '24

20 Apr '24

Hello I'm using Ubuntu 20.04 with LXQt (i.e., Lubuntu) on the remote computer. When I'm using the computer locally and plug in an USB drive, It will be automatically mounted and shown in file explorer. But when I'm using the computer remotely, I'll just get a prompt saying "Error: Not authorized to perform operation" Could someone help me to configure the remote computer so that when I plug in an USB drive, it would behave as I would use the computer locally? Best regards and greetings from Finland Kalle
