X2goclient fullscreen does not adjust screen resolution after update
by christoffer krakou 08 Jan '24

08 Jan '24

Hello list I have recently upgraded the following packages Upgrade package libnx-x11 2:3.5.0.16-0~278~precise1 to 2:3.5.0.17-0~320~precise1 Upgrade package libxcomp3 2:3.5.0.16-0~278~precise1 to 2:3.5.0.17-0~320~precise1 Upgrade package libxcompext3 2:3.5.0.16-0~278~precise1 to 2:3.5.0.17-0~320~precise1 Upgrade package libxcompshad3 2:3.5.0.16-0~278~precise1 to 2:3.5.0.17-0~320~precise1 Upgrade package nxagent 2:3.5.0.16-0~278~precise1 to 2:3.5.0.17-0~320~precise1 Upgrade package nxproxy 2:3.5.0.16-0~278~precise1 to 2:3.5.0.17-0~320~precise1 Upgrade package x2goagent 2:3.5.0.16-0~278~precise1 to 2:3.5.0.17-0~320~precise1 On my Ubuntu 12.04 server. Now, when i connect using the x2goclient, it works well when i select a resolution and run it in a window, but when i select fullscreen, the resolution is 1920 X 1200, no matter the resolution on the client monitor. This results in the Unity controls being unusable. Before the upgrades, there were no trouble. Is anyone else experiencing the same? -- Venlig Hilsen / Best Regards Christoffer Krakou Fleten.net APS

loginctl 'enable-linger' causes systemd --user to respawn on boot
by Montjoy, Robert (montjoy) 28 Sep '23

28 Sep '23

Hi. At one time "loginctl enable-linger" was added to the x2gostartagent to make sure the systemd did not kill the x2go process on disconnect. This has had the probably undesired affect of having systemd --user username being executed on boot for every x2go user. At the last boot about 70 processes (one for systemd and one for pam) were spawned. This is probably not what we want. Is there a better way to handle the systemd termination issue? Should something like systemd-run --scope --user x2goagent ..... be used instead? Or can x2go cleanup this entry on termination? Maybe have x2gocleansessions do it? Note: I will probably cleanup /var/lib/systemd/linger on boot by executing rm -f /var/lib/systemd/linger/* but that it is more of a "hammer" approach than anything else. Thanks in advance. Rob

Bug#1469: X2Go Client connection issue (Socket error)
by Melroy van den Berg 29 Jun '23

29 Jun '23

Package: x2goclient Version: 4.1.2.2 I often get an error message when I try to connect to my Debian buster docker image, running x2goserver and XFCE, via the X2Go Client on my host machine. It will give the following error message (when using the --debug flag on the x2goclient): x2go-DEBUG-../src/sshmasterconnection.cpp:2071> "ssh_channel_open_session failed": "Socket error: No such file or directory" x2go-DEBUG-../src/sshprocess.cpp:478> I/O error: "ssh_channel_open_session failed."" - Socket error: No such file or directory" (0). I created a detailed video, I posted it on YouTube, please take a look at the video: https://youtu.be/LAlLtBNTIUo Logging details, reproducibility and more is explained in the video itself. You'll notice that I can sometimes connect to the XFCE session and sometimes I can't. Although connecting via the ssh cli command is always working without any issues. Meaning there is really some kind of bug in the X2Go Client. I'm afraid. Again, I really hope somebody could help me in finding the root-cause and fixing the issue. Since I really love X2Go. And I would like to use this tool in production. I'm also a software developer so maybe I can help debugging the problem. Similar (same) bug is reported in the past (from 2019): https://lists.x2go.org/pipermail/x2go-user/2019-March/005512.html All the details regarding this Docker image and setup can be found in this git repo: https://gitlab.melroy.org/melroy/xfcevdi See attachments for additional debug logs of the client itself. One when successful and one during the error. Thanks in advance! Kind regards, Melroy van den Berg Ps. You can contact me by mail of course. But I can understand that debugging this issue would be preferable be done via VoIP for example.

Bug#1434: Use login shell for session
by Orion Poplawski 30 May '23

30 May '23

Package: x2goserver Version: 4.1.0.3 Tags: patch X2Go's Xsession file always starts the user's session with /bin/bash (at least on RedHat systems where SHELL is set to /bin/bash via ~/.bashrc calling /etc/bashrc). This patch attempts to determine the user's login shell and use that for launching the session. See also: https://bugzilla.redhat.com/show_bug.cgi?id=1794660 Another option might be the judicious use of the --norc option when launching x2goruncommand on followers but I'm not sure what other effects this will have or where to do that. Effects might not be to bad because I can simulate this by moving away the user's .bash_profile and .bashrc files and then the tcsh is used as expected in this case. However, while $SHELL does not get set in this case, the xfce4-session script still gets launched with bash which triggers some other errors, so this patch may be the best option. --- x2goserver-xsession/etc/Xsession | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/x2goserver-xsession/etc/Xsession b/x2goserver-xsession/etc/Xsession index 270a0b3..522f37e 100755 --- a/x2goserver-xsession/etc/Xsession +++ b/x2goserver-xsession/etc/Xsession @@ -117,6 +117,10 @@ if ! echo "*" >>"$WRITE_TEST"; then fi rm -f "$WRITE_TEST" +# Determine the users login shell and use that to launch the session +SHELL=$(getent passwd $LOGNAME | cut -d: -f7) +# Fallback +[ -z "$SHELL" ] && SHELL=/bin/bash if [ -f /etc/debian_version ] || [ -f /etc/devuan_version ]; then -- 1.8.3.1 -- Orion Poplawski Manager of NWRA Technical Systems 720-772-5637 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion(a)nwra.com Boulder, CO 80301 https://www.nwra.com/

Bug#1357: pyhoca 0.6.0.1 incompatible with x2goserver 4.1.0.3
by Chris Greenshields 30 May '23

30 May '23

Package: Pyhoca Version: 0.6.0.1 I tested all combinations of the following recent releases of the following software from the ppa:x2go/stable and ubuntu repositories: + x2goserver + 4.1.0.0-3 (ubuntu) + 4.1.0.3-0~1708~ubuntu18.04.1 (ppa:x2go/stable) + x2goclient + 4.1.1.1-2 (ubuntu) + 4.1.2.1-0~1788~ubuntu18.04.1 (ppa:x2go/stable) + pyhoca-cli + 0.5.0.4-1 (ubuntu) + 0.6.0.1 (ppa:x2go/stable) There is one combination that did not work: x2goserver 4.1.0.3-0~1708~ubuntu18.04.1 (ppa:x2go/stable) with pyhoca-cli 0.6.0.1 (ppa:x2go/stable) It failed with the following message, which I assume is a bug: " a bytes-like object is required, not 'str' pyhoca-cli: error: the remote server does not have the X2Go Server software installed "
