Mounting of home dir is failing
by Neal Becker 29 May '22

29 May '22

Just noticed that mounting of my home dir is failing. In journal I see: May 29 08:02:40 nbecker8 /usr/bin/x2gomountdirs[878032]: WARNING: mounting of /home/nbecker failed May 29 08:02:41 nbecker8 /usr/bin/x2gomountdirs[878032]: WARNING: mounting of /home/nbecker/.x2go/S-nbecker-50-1653825344_stDMATE_dp24/spool failed In /home/nbecker/.x2go/C-nbecker-50-1653825344_stDMATE_dp24/sshfs-mounts.log: read: Connection reset by peer read: Connection reset by peer read: Connection reset by peer read: Connection reset by peer I don't know when this started failing as I don't use it much. Perhaps related to upgrade of client to fedora 36? ssh login without password is working fine. Any ideas? Thanks, Neal

GTK4 apps
by Jonah Benton 27 May '22

27 May '22

Hi folks, I recently upgraded to Fedora 36 which includes more gtk4 versions of apps and discovered that they don't work in x2go: [jrb@fedora ~]$ ldd /usr/bin/gnome-chess | grep gtk libgtk-4.so.1 => /lib64/libgtk-4.so.1 (0x00007fb628e7b000) [jrb@fedora ~]$ gnome-chess (gnome-chess:2552687): Gdk-ERROR **: 07:55:29.217: XInput2 support not found on display Trace/breakpoint trap (core dumped) >From a cursory googling around this issue it appears there isn't anything on the user side that can be done about this on an app-by-app basis, is that right? Cheers, thanks, Jonah

Performance on external monitor
by Jonah Benton 25 May '22

25 May '22

Hi folks, Super happy x2go user on a Thinkpad P1 Gen2 with a 4k screen running Fedora with XFCE. I segregate clients and personal work into distinct users and run 5 or 6 x2go sessions at the same time, switching between them with desktop workspace hotkeys monitored by the master session. Performance is great, even video within an x2go session is terrific. Today the Thinkpad's screen decided to start to fail, so I connected the laptop over HDMI to a 4k external monitor. Now, unfortunately, x2go performance is really suffering- window repaints within a session even with only 1 session are so slow as to be essentially unusable. Window repaints and other rendering activity on the master X session seem about the same. All sessions are 3840x2160, using "LAN", "16m-jpeg", image quality 9. I played a little with those settings but nothing made a material difference. I don't know anything about the X display architecture or the hardware path. Any thoughts from anyone who does on any options to improve x2go performance on an external monitor? Thanks, cheers, Jonah

[Debian repository] stable link points to buster instead of bullseye
by richard lucassen 21 May '22

21 May '22

@ the Debian repository admin: When running "apt update" I get this warning: W: Conflicting distribution: http://packages.x2go.org/debian stable InRelease (expected stable but got buster) In /etc/apt/sources.list.d/x2go.list I have: deb http://packages.x2go.org/debian stable main I think there the "stable" link points to buster: http://packages.x2go.org/debian/dists/ R. -- richard lucassen http://contact.xaq.nl/

No connetion after Update to Ubuntu 22.04 (Openssh)
by T. Wirth 16 May '22

16 May '22

Hi, with latest version of Ubuntu I'm getting an error when trying to connect with windows x2go client to Ubuntu 22.04 machine (I think it's not so relevant that it's ubuntu 22.04 but newer openssh version 8.9): "kex error: no match for method kex algos:server [Diffie-hellman-group-exchange-sha256], client [curve255519-sha256(a)libssh.org,ecdh-sha2-nistp256,Diffie-hellman-group14-sha 1,Diffie-hellman-group1-sha1]" I have tried to adapt sshd_config via: "HostKeyAlgorithms ecdsa-sha2-nistp256-cert-v01@openssh.com,ecdsa-sha2-nistp384-cert-v01@openss h.com,ecdsa-sha2-nistp521-cert-v01@openssh.com,ssh-ed25519-cert-v01@openssh. com,ssh-rsa-cert-v01@openssh.com,ssh-dss-cert-v01@openssh.com,ecdsa-sha2-nis tp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,ssh-ed25519,ssh-rsa,ssh-dss" After that I have restarted sshd service but that did not help. I also tried: HostKeyAlgorithms ssh-rsa,ssh-dss PubkeyAcceptedKeyTypes ssh-rsa,ssh-dss The error message is the same. So I assume that the error is not what the message is telling me but I know that with some of the latest openssh versions several other clients run into problems (putty latest versions fixed it, jump desktop - setting PubkeyAcceptedKeyTypes=+ssh-rsa did work) Any ideas?

All windows nightly build .exe file have new time stamps?
by 4dacres＠gmail.com 09 May '22

09 May '22

Was looking at the nightly builds, and noticed that all the .exe files had the same date/time stamp (back to the 2019 builds). Is that expected?

Broker and file sharing
by Brian Sanders 08 May '22

08 May '22

I am looking at the settings in my x2gobroker-sessionprofiles.conf, and it seems to indicate the broker can set some defaults to turn off allowing printers, and filesystems to be shared. useexports=false print=false I have tried turning these on, and I don't believe they are working. Specifically if I connect to the broker, then a server it servs out. Once connected, I can use the x2go Client window's share folder button. In there I can define an export, and then highlight it and press share. This will then show up on the workstation. Am I missing something? What do these options do if not turn on/off the ability for the user to make these shares? If I wanted to disable these shares/printing, and then enable them for specific hosts by overriding it, are there other options I can activate to achieve this?

x2go server on debian: readonly partition
by Vikas Rawal 02 May '22

02 May '22

I am running x2go server on debian testing and connecting to it from another linux machine. Everything works fine but occasionally (approximately after 2-3 days of use over which I connect and disconnect from the client many times), the host machine says the /tmp/... is on a read-only partition, and everything stops working. x2go client does not connect when this happens. I can ssh to the server but nothing works on it. I am unable to even cleanly reboot the machine when that happens. I only need to physically hard-boot the machine. I don't know if this is happening because of x2go, but it never happened before I started dabbling with x2go. Is this a known problem? Any ideas about how to debug? V.

Suspend on disconnect
by Vikas Rawal 30 Apr '22

30 Apr '22

Does x2go cleanly suspend if the client loses connection or the laptop running the client is just suspended by turning the screen shut? Do the user systemd services keep running when x2go session is suspended? Something like what would happen when a tmux/screen session is detached. V.

Unlock screen in KDE
by Klaus Vink Slott 24 Apr '22

24 Apr '22

Not really a X2go problem, but we use X2go at the IT University of Copenhagen. I prefer to use it with KDE, and apart from the slow startup it works really well against our Centos 8 servers. As I mostly like to run full screen to ensure that Alt+Tab and other shortcut operates as expected. But this gives one problem: When I leave my workstation I am used to lock my keyboard by pressing Ctl+Alt+l but this in full screen this locks the remote desktop - and I find no way to unlocking it again. As a workaround I changed the lock keycombination on the remote, but I would like some proper way to unlock the remote. Any suggestions? -- Regards Klaus
