username sessions begin even after reboot without login on Ubuntu 20.04
by h i 26 May '21

26 May '21

Hello, Recently working on a new system using x2go on Ubuntu 20.04 linux. Noticed something different that we never experienced previously on 18.04. Reboots usually clear all sessions per user. After reboot on 18.04, you would see the following output from the linux command: %ps -elf | grep username 4 S username xxxx 1 0 80 0 - xxxxx - 15:20 ? 00:00:00 /lib/systemd/systemd --user 5 S username xxxx xxxx 0 80 0 - xxxxx - 15:20 ? 00:00:00 (sd-… [View More]

Request for assistance - x2go HTML client
by Jan Bergner 22 May '21

22 May '21

Hello all, I am trying to set up the x2go HTML client on a Debian server following this instruction: https://wiki.x2go.org/doku.php/wiki:advanced:x2gohtmlclient My setup is done with Ansible, so the setup can be reproduced. The git repo containing the role can be found here: https://gitlab.com/jbergner/ansible-x2go-htmlclient Right now, it should be considered a BETA version (using snakeoil-certificates, etc.), but that is not the point. The x2go HTML client is accessible and it seems to be … [View More]starting a session. However, this session is closed shortly after the initialization. Unfortunately, I cannot seem to find out, why.

AFAIKS freenode is not the network of choice anymore: https://mniip.com/freenode.txt So should we move to libera? Or elsewhere? Or drop the chat altogether? Uli

Session terminated instantly, seemingly with no errors

Hello, I have been trying to figure this out for a while now. Every time I start a session from my client (arch) to my server (arch xfce), the session seems to start fine, but terminates instantly.

Re: [X2Go-User] Removing "Suspend X2go Session.." in Ubuntu Mate desktop System Panel , 20.04
by h i 16 May '21

16 May '21

Okay, Thanks. I was able to get it to suspend using both methods. That was a mistake on my part. Too many x2go client windows open. Using the command line x2gosuspend-session worked and properly suspended the session. Clicking on the item from the mate desktop menu worked as well. Thanks for providing insight on how this menu item is now coded in the Mate-panel applet with 20.04. It looks like it can't be removed easily. Since it just provides an additional option for suspending the session,… [View More]

Removing "Suspend X2go Session.." in Ubuntu Mate desktop System Panel , 20.04
by h i 16 May '21

16 May '21

Hello, How can you remove the "Suspend X2Go Sesseion..." item from the Ubuntu Mate System panel? [cid:8d0d43b2-6e97-4a50-87a4-d76edbc29ab6] In Ubuntu 18.04, this was linked with x2gomatebindings. Uninstalling the bindings removed it. However, with Ubuntu 20.04, I could not locate x2gomatebindings in the Ubuntu repository. I want to remove it because we don't need it and it doesn't work well with x2go client. Clicking on the item makes the desktop session disappear, but the x2go client … [View More]

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Handbrake itself is probably fixed for me , but x2go is still troubling me, now I _can_not_ reconnect to running session anymore, instead there is a small Window, indicating there is a running x2go session, but the Resume button is greyed out... I wonder, whether you should continue to provide stable packages for Debian bulls-eye, since the native Debian packages are not usable, or could it be I was not testing them thoroughly enough?? … [View More]

Re: [X2Go-User] x2goserver Requires: base64

Thanks, Mike, I already had the executable so the "yum update --skip-broken" it proposed did the trick but I was flagging it as a possible package dependency issue. I've never done package building but for folks who build the x2go rpms, changing the dependency from it needing the "base64" package to it needing the "coreutils" package would resolve the: > x2goserver-4.1.0.4-0.0x2go1.0.git20210418.1930.heuler.el7.x86_64 > (x2go-nightly-epel) > Requires: base64 resulting in … [View More]a smoother install.
