Huge session.log files in user /tmp folder
by Mark Lamers 11 May '21

11 May '21

Hi, We run a x2go server for scientists who while worjk with python and R scripts on large data sets. However some user create immense large session logs in /tmp/.x2go-$user/$user-XX-XXXXXXXXXXX_stDMATE_dp32/session.log. These a sparse files but a certain point fill up out /tmp partition. Is there a way to reduce these files or set a max size per user? Regards Mark

Automatically select New session when there are already other sessions from other client
by Bambang P 07 May '21

07 May '21

How can we force the user to select New session when on connect there are already other sessions from other client? To be clear, here is the scenario 1. HQ computer run the x2go server 2. Computer 1: a supervisor run x2go client and accessiong the server 3. Computer 2 want to access the server, after authenticate the connection he is then presented with Select session form with the computer 1 session listed. If the he double click the computer 1 session, he is hijacking the computer 2 session. How can I prevent this situation? Is there a way to force so he can only create a new session? -- Bambang P http://bpranoto.blogspot.com

Wayland launch scripts being used?
by Jeff Sadowski 04 May '21

04 May '21

So I'm not sure why so many of my desktops in Fedora have stopped working with x2go but I heavily suspect it is them transitioning all desktops to wayland. I know gnome still has an option to select xorg from the console but x2go does not provide any clarification on this kind of selection. Maybe if I understood how the server side selects the script to run to start the desktop depending on the selection from the client side I could help the package maintainers make things easier for x2go users. All I know for certain is: I was using XFCE desktop in Fedora 33 when I upgraded to Fedora 34 XFCE became unusable over x2go. I started trying other desktops and noticed they do not act right. Gnome over x2g on fedora 34 doesn't even start. KDE seems to have some issues. Mate seems to work.

Frozen Login Screen "kscreenlocker_greet"
by Thomas Roebbenack 04 May '21

04 May '21

Is there any problems known about frozen sessions at reopen it after a some time? - This problem occurs since 3 days now, don't know why and what exactly happen (probably system updates). Before it worked without problems. - I working on "Ubuntu 20.04.2 LTS" and KDE Plasma Desktop (5.18.5) (Framework 5.68.0, QT 5.12.8) What exactly happen: - Open a session working as expected (with opened Session/Window the Screenlocker occurs, but I can move the mouse and enter the password) - After closing the window (the session runs in the background), I can reconnect after a short time ~10 Minutes, the screenlocker occurs, but I can move the mouse and enter the password. - But, after a longer time (don't know exactly how long), If I reconnect the screenlocker occurs, but the screens seems to be frozen. I can move the mouse, nothing happen, try to enter some keys, nothing happen. Looks like the screensaver is dead. The CPU load of 1 core is 100% (kscreenlocker_greet + a x11 process). -> The only thing that worked at the moment, try to open a second session gives me the possibility to close the first one, than I can reconnect. But I have to kill (-9) the both running processes to stop feed my CPU load. -> Disable the screensaver is no option, because there exists a directive to use it. Any suggestions? Any Ideas? Thank you in advance. Thomas

mouse 1 cm too low
by richard lucassen 17 Apr '21

17 Apr '21

Hello list, I have run x2go for many years now without any problem. I have two different servers running Debian testing and x2go 4.1.0.3-5, multiple clients running the same OS and x2go client. I run WindowMaker both on client and servers. This has worked for many years. Weird thing: the active clicking point for the mouse is 1 cm above the mouse. Restarting client and server does not make any difference. AFAIK these x2go versions have not changed (underlying libraries might have of course). I tested this on a few clients: same problem. It make x2go almost unusable. Anyone a hint what to test and where to look for this weird issue? R. -- richard lucassen http://contact.xaq.nl/

Multiple connexion with the same user name
by kanssoune.saliya＠external.tractebel.engie.com 06 Apr '21

06 Apr '21

Hello everyone ! I would like to configure remote login to CentOS 7 servers using x2go and allow multiple login with the same user i.e. many users use the same ID and password to log in at the same time. Does x2go allow it? I explain below a little bit more our infra : * We use NIS as user authentication * We have more than 10 different Linux workstations * Each colleague can connect on every workstations * We use generic account for some purpose i.e. many users use the same ID and password Do you thing that this is possible to configure with x2go? If yes, what are the steps to follow? What desktop environment (MATE, XFCE, GNOME ...) will be best adapted? Thanks! ENGIE Mail Disclaimer: http://www.engie.com/disclaimer/

One application (Digikam) fails, apparently randomly
by Chris Green 02 Apr '21

02 Apr '21

Well I'm very confused now, I thought I could see a pattern but I can't. I'll report what I have discovered so far though. I'm running x2gclient 4.1.2.2 (as installed from the Ubuntu repositories) on my xubuntu 20.10 laptop. I'm running the server on my xubuntu 20.10 desktop machine, again just as installed from the Ubuntu repositories:- x2goserver: 4.1.0.3 x2goserver-common: 4.1.0.3 x2goserver-extensions: 4.1.0.3 x2goserver-fmbindings: 4.1.0.3 x2goserver-printing: 4.1.0.3 x2goserver-x2goagent: 3.5.99.24 x2goserver-xsession: 4.1.0.3 I have been trying a mix of three types of session, as follows (with results):- 1 - A small Python GUI program as a 'Single Application', this always runs without any problem at all, it just works every time. 2 - An XFCE session, this works every time and doesn't cause any major issues but it does occasionally pop-up windows in the server session as follows:- A window saying "Authentication is required to create a colour profile" and I have to enter my sudo user password. After the above pop-up I sometimes get a second one saying "Authentication is required to operate a colour managed device" The above two pop-ups only appear occasionally, usually the XFCE session just starts up and runs normally. Once I've entered my sudo password in response the session runs OK. 3 - A Digikam session as a 'Single Application', this does work sometimes but more often it appears to start OK, then xfwm4 on the *client* crashes and the Digikam session disappears even though it is still running on the desktop machine. I can't see any consistent reason for when it does work or when it doesn't work. Digikam is running from a big Appimage. Running digikam in an XFCE session running in x2go works perfectly, or at least I've not managed to crash it ever. It's only when run as a 'Single Application' that it fails. I guess I can just run Digikam in an XFCE session but I'd like to be able to just run Digikam. It's frustrating that it sometimes works but I can't see what is needed for it to work. As I said elsewhere I've run memtest on the desktop machine for two whole passes and it showed no errors. I'm happy to add debug flags to either end to see if it's possible to diagnose this. -- Chris Green

Cant start X.Org Server
by Martti Pitkanen 01 Apr '21

01 Apr '21

Hi, I experimented different settings in my Win X2Go -client, after which I started getting "x2client Cant start X.Org Server. Please check your installation." Afre that X2Go closes. I uninstalled it and removed all references to x2go by using regedit. Any idea what else I can do? Thanks, Martti Pitkanen
