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-pam) However, after reboot on the Ubuntu 20.04 system, I see the following output: 4 S username XXXX 1 0 80 0 - XXXX - 20:44 ? 0:00:00 /lib/systemd/systemd --user 5 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 (sd-pam) 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/bin/pulseaudio 0 S username XXXX XXXX 0 99 - - XXXX - 20:44 ? 0:00:00 /usr/libexec/tracker-miner-fs 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/bin/dbus-daemon --session --address=systemd: --nofork --nopidfile --systemd-activation --syslog-only 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/gvfsd 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/gvfsd-fuse /run/user/1020/gvfs -f -o big_writes 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/gvfs-udisks2-volume-monitor 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/gvfs-gphoto2-volume-monitor 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/gvfs-afc-volume-monitor 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/gvfs-mtp-volume-monitor 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/gvfs-goa-volume-monitor 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/goa-daemon 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/goa-identity-service This behavior occurs after login to x2goclient for just one time. The usernames appear in the "top" commmand output with goa-identity-se process despite not logging for a x2goclient session after a reboot. Is there some setting one can change in x2go for Ubuntu 20.04, so these processes aren't running if a person hasn't logged in x2goclient session after reboot? Thanks. h.

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 starting a session. However, this session is closed shortly after the initialization. Unfortunately, I cannot seem to find out, why. May be, someone can help? From start to end of the session, I get the following in the nginx access log: 192.168.122.1 - - [10/May/2021:22:38:57 +0200] "GET /assets/x2go-plugin/IMG/x2gobg.svg HTTP/1.1" 200 10261 "https://192.168.122.126/assets/x2go-plugin/" "Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0" 192.168.122.1 - - [10/May/2021:22:39:04 +0200] "POST /assets/x2go-plugin/RPC/x2gorpc.cgi HTTP/1.1" 200 2180 "https://192.168.122.126/assets/x2go-plugin/" "Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0" 192.168.122.1 - - [10/May/2021:22:39:19 +0200] "GET /x2gows/50001 HTTP/1.1" 101 17 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0" nginxes error log: 2021/05/10 22:38:58 [error] 1516#1516: *2 FastCGI sent in stderr: "Scalar value @out[2] better written as $out[2] at /var/www/html/assets/x2go-plugin/RPC/x2gorpc.cgi line 79.

Move from freenode?

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
by Matteo Guareschi 19 May '21

19 May '21

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. The client reads: Info: Proxy running in server mode with pid '11128'. Session: Starting session at 'Sun May 16 15:24:13 2021'. Info: Using errors file '/home/matteo/.x2go/S-matteo-50-1621203851_stDstartxfce4_dp24/sessions'. Info: Using stats file '/home/matteo/.x2go/S-50/stats'. 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. Info: Connecting to remote host 'localhost:40084'. Info: Connected to remote proxy on FD#5. Info: Connection with remote proxy completed. Loop: WARNING! Unrecognized session type 'unix-kde-depth_24'. Assuming agent session. Warning: Unrecognized session type 'unix-kde-depth_24'. Assuming agent session. Info: Using ADSL link parameters 1408/24/1/0.

And the error files in the S-matteo-50-[...] directory are sessions, options and a spool dir. Sessions only says what versions were found. On the server side in the C-matte-50 directory session.log gives the rather uninteresting errors: Error: keyboard file not created: Is a directory Error: Aborting session with 'Could not open default font 'fixed''. before terminating. The system log itself /var/log/user.log does not report any errors, but only terminates the session. The clients file reports only: error opening security policy file /usr/local/lib/nx/X11/xserver/SecurityPolicy At this point I have exhausted my resources. I have tried the client from a different OS and the result is the same. From what I understand the fixed font error is most likely a red herring, but I have installed xorg-fonts-misc for what it's worth, with no difference. Lastly I should mention that the server runs xfce4 fine on the machine itself (using dbus-launch also makes no difference). I would really appreciate any help. -- Matteo Guareschi

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, removing it most likely isn't necessary. Thanks again. h ________________________________ From: Mike Gabriel Sent: Sunday, May 16, 2021 3:34 PM To: h i Cc: x2go-user(a)lists.x2go.org Subject: Re: [X2Go-User] Removing "Suspend X2go Session.." in Ubuntu Mate desktop System Panel , 20.04 Hi, On So 16 Mai 2021 21:08:45 CEST, h i wrote: > 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.

The "Suspend X2Go Session..." menu item is now coded into the corresponding MATE panel applet (via librda). Currently, there is no "switch" to disable it, but it could be a feature request. The other issue is that X2Go Client does not recognize the session suspension properly when done from inside the session, it seems. If you open a terminal in the X2Go session and issue the command x2gosuspend-session on the command line, do you observe the same behaviour? (i.e. session goes away, but X2Go Client does not get it?)

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 window says the session is still running and doesn't disappear. Thanks. h.

-----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??

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 a smoother install.

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
