Setting up passwordless session
by funk minion 24 Jul '20

24 Jul '20

Using windows client 4.1.2.0, I'm wanting to set up passwordless authentication. I've followed these instructions.... https://wiki.x2go.org/doku.php/wiki:advanced:authentication:passwordless-ssh ...but am still receiving a small modal dialog box prompting for an account password."Enter user account password:" In the settings for the session, "Use RSA/DSA key for ssh connection:" points to my local private key file and "Try auto login (via SSH Agent or default SSH key)" is checked Question: Is 'auto login' required for passwordless login? Question: Does the term 'default SSH key' reference the id_rsa key created by the ssh-keygen.exe or something else? Question: Does passwordless login require the use of Pageant or other tools, or can it be accomplished solely with x2go settings? thx.

How to scale remote apps on laptop 4k hidpi displays?
by Leho Kraav 16 Jul '20

16 Jul '20

Hi I'm running a 3840x2400 laptop display in 200% scaled mode, on gnome-shell-3.36. x2goclient-4.1.2.2 UI can be fixed up with QT_AUTO_SCREEN_SCALE_FACTOR=1. But remote apps still launch in native resolution, making everything tiny small. This happens for both Wayland and Xorg-based Gnome session. Is there a solution to getting the remote x2go session match the current scale of local display? Mailing list searches for "hidpi" etc failed to find anything useful. -- Leho Kraav, senior technology & digital marketing architect

Connection failed session ... terminated
by Andrew Munn 13 Jul '20

13 Jul '20

I'm running the Windows client v4.1.2.2. Server is CentOS 8. I connect and double-click on the row here: [image: image.png] Then I get this: [image: image.png] This problem happens frequently on all my servers. I can click "New" and open a session but I can never successfully reconnect to that other listed session. I think deleting something from /tmp fixed this in the past. Sound right? Why does this always happen?

Hi, I am able to connect from windows x2go client to the broker server (installed in Ubunt 20.04), And I have created a session profile in /etc/x2go/broker/x2gobroker-sessionprofiles.conf file [test-192.168.0.27] user= name=test-192.168.0.27 host=192.168.0.27 command=KDE usebrokerpass=true fullscreen = true broker-session-autologin=true But when I select "test-192.168.0.27" session, it gives Authentication error of Access denied.

Configure x2go-client to not forward specific key combinations?
by Jonah Benton 10 Jul '20

10 Jul '20

Hi folks, I'm interested in using x2go to: * connect into several individual accounts/machines at the same time * use each remote machine desktop in full screen mode * switch between remote full screen desktops using a specific key combination, which would therefore not be sent to the remote Is this possible? In my initial perusal of man pages and testing I don't see a way to do what seems to me to be the (probably wrong) solution- instruct the x2go-client (in either launch remote desktop mode, or desktop screen sharing mode) to not capture a specific key combination (like control-alt-right arrow and control-alt-left arrow) so that the parent desktop can handle them (e.g. switch between parent-side virtual desktops). I'm using Fedora / XFCE for all systems. Thanks very much in advance! Jonah

Client GUI for connecting to broker
by Iain Hallam 09 Jul '20

09 Jul '20

Hi. I'm considering using X2Go broker to implement load balancing for some Linux servers, but many of our users are on Windows devices. Getting them to run the command line options to connect to a broker is going to be tricky; it would be much more useful if we could get them to click on a button, paste in an address, and then they're off and running. Is there any scope for adding a way in the client to connect to a broker from the GUI? Thanks, Iain Hallam.

x2go session failure because of unknown "localhost"
by flegoff 23 Jun '20

23 Jun '20

Hello list, I have been using x2go without issues for a long time until recently. Both client and server are running on Linux machines. I can connect to the server (via an SSH proxy). I get the "New session started" notification. But the session is apparently terminated because tere is some error resoling the display server. I copy pasted the log messages in the enclosed file. I think the important part is this: Loop: WARNING! Overriding auxiliary X11 port with new value '1'. Warning: Overriding auxiliary X11 port with new value '1'. Info: Using abstract X11 socket in kernel namespace for accessing DISPLAY=:0. Error: Failed to resolve address of 'localhost'. Loop: PANIC! Unknown remote host 'localhost'. Error: Unknown remote host 'localhost'. Session: Session terminated at 'Fri Jun 19 22:50:42 2020'. As far as I remember I haven't changed client or server configuration. I did switch from using Published App sessions to Xfce session to I have installed Xfce on the server. Published App sessions do not work either now. Any idea what is going on here? Or how to debug this? Cheers, Fabrice

keyboard config on wayland
by Neal Becker 22 Jun '20

22 Jun '20

Both client and server are Fedora (31 and 32). I'm running a kde/wayland client, with capslock mapped to ctrl. When I connect to the server (running mate) everything works fine, except I don't have capslock mapped to ctrl. Every time I connect (not every time the session starts) I have to run setxkbmap -option caps:ctrl_modifier Oh actually one thing doesn't work. Cut/paste is totally nonfunctional. -- *Those who don't understand recursion are doomed to repeat it*

Problems using HTML5 kvm console
by Simon Beißer 20 Jun '20

20 Jun '20

Hello everyone, we use x2go in our company and it works really well. However, currently we have noticed two problems that occur in connection with an HTML5 KVM (remote console) client. Maybe one of you has an idea about these issues. 1st question When using the keyboard within the KVM console, we noticed that the arrow down key is incorrectly assigned and triggers an Enter. With the help of a keycode event tool I found that the NumpadEnter is transmitted there, see screenshot in the appendix. It seems that the wrong physical key (key code) is transmitted via x2go/nx. This has nothing directly to do with the keyboard layout used and therefore unfortunately cannot be changed within the virtual console. Is this error known? Is there a fix for it? 2nd question OpenGL/GLX is required for the KVM console. Unfortunately, only GLX1.2 is in use among the current nx-libs, which is why this does not work in Firefox. I have found only VirtualGL as workaround. Do you know other methods to make such applications running? Best regards Simon
