postgres session backend, ldap users first login and pam_mkhomedir
by Ja Bi 15 Mar '19

15 Mar '19

Hi, I try to run x2go with postgres as session backend. I have users in ldap database and i would like to use pam_mkhomedir when user connects with x2 goclient/pyhoca for the first time, so i have no $HOME, no $HOME/.x2go and no $HOME/.x2go/sqlpass. I tryied x2godbadmin --addgroup x2gousers from https://wiki.x2go.org/doku.php/wiki:advanced:multi-node:x2goserver- pgsql but 1) group is from ldap/sssd (i think i must switch on sssd enumerate to get members of ldap groups :( ) 2) x2godbadmin does "sub add_user()" so it creates $HOME/.x2go of group members (and it creates it under user who runs x2godbadmin - so $HOME owner is root ) and pam_mkhomedir does not take efect so... How do you set up this scenarios? x2goserver-4.1.0.0-0.0x2go1.1.git20180302.1517.main.x86_64 SUSE Linux Enterprise Server 12 (x86_64) VERSION = 12 PATCHLEVEL = 0 thank you very much H.

Clipboard stops working
by Norm Green 11 Mar '19

11 Mar '19

Hello List, I find that the clipboard stops working after a period of time. Specifically, copying from the windows desktop to the x2go window doesn't work because x2go thinks the clipboard is empty. I am copying from emacs on Windows to emacs on Linux. It doesn't matter how many times I select and copy on windows, x2go does not pass the clipboard contents to emacs on Linux. But if I disconnect from the server and reconnect, it works, using the same emacs windows. This is with x2go client 4.1.1.1 running on Win7, but it also happened on previous x2go client versions (4.0.x) . x2go server 4.0.1.20 is running on Ubuntu 16.04 Is this a known bug? Any way to fix it? Norm Green

Connection timeout over high latency network links
by Brent Roman 08 Mar '19

08 Mar '19

I'm trying to run a remote X-session on a satellite link. The ping latency is typically 800ms. I have no trouble ssh'ing to the remote machine, but, whenever I try to connect a remote session via the x2goclient, it ends within a couple seconds with a dialog box saying: Timeout connecting to raven raven is the remote hostname. Both machines are running Debian Jessie. The x2goclient is version 4.4.1.0 Is there some connection timeout parameter that I could increase to make it possible to use high latency links? Is this fixed in newer versions? Thanks! -- Brent Roman MBARI Software Engineer Tel: (831) 775-1808 7700 Sandholdt Road, Moss Landing, CA 95039 mailto:brent@mbari.org http://www.mbari.org/~brent

Could the desktop session be initiated in batch mode on the server side?
by Pontiggia, Francesco 07 Mar '19

07 Mar '19

Hello, I am trying to understand if x2go can be used for a specific use case I am working on. Our team manages an HPC linux cluster for researchers at our University. We have an interactive computing portal that allows users to schedule interactive jobs on our cluster, including Remote Desktop sessions that are not in the login space, but run as jobs on the compute nodes . At the moment we use VNC + Xfce to setup those sessions. The job gets started by the SLURM scheduler on the compute nodes, and the job script (run as the user who submits the job) starts up a vncserver and xfce4-session. Users can then connect to their sessions either via noVNC or with a regular VNC client. The performance of our current setup does not match the needs of some of our users and I am looking for alternatives for those specific edge cases. >From what I understand from reading the docs and to the extent of my limited personal experience with X2go, X2go is typically setup as a login solution, where the session is typically started from when the client logs in. I was wondering if there was a way in which I could configure the software to match as close as possible our current Remote Desktop session compute jobs setup. In particular, can I have the desktop session started from a batch job and then sit and wait for the client to connect? And could I configure things so that clients connecting will only be able to attach to existing sessions and not initiate new ones? Thanks for any advise you might have. Best Regards Francesco

x2gobroker on CentOS 7
by quetengoqueponeraqui 05 Mar '19

Hi guys, I’m trying to install the broker on a CentOS 7 machine (rpms not on epel, so downloading from x2go’s repos) but it complains about several python3 dependencies. Even with python36 installed it cannot find python3 and related packages. Any idea? Cheers

Agent Terminated Unexpectedly. Aborting Session Startup
by Ioannis Vlachos 04 Mar '19

04 Mar '19

Hi, I’m using X2Go daily for years now. Today, while using a session, X2go crashed and that’s where it all started. Server is a Centos 7 using XFCE and client is a Mac. 90% of the times a crash happens (rarely), I can resume the session and 10% I have to start a new one. This time it was different and started my ordeal: When trying to reconnect, I got a dbus error (failed to connect to socket, dbus connection refused). Still got some sort of session but windows were all over the place and was unusable. Reinstalled dbus, x2go and removed .x2go from client and server, as well .cache. Reinstalled xfce, removed xfce, and installed MATE. All these did not happen in one go. A trillion of step by step trials and errors (practically only errors) Now, I can connect to MATE via ssh X11 (XQuartz). It works. However, X2go refuses to connect with: Agent Terminated Unexpectedly. Aborting Session Startup Log files are not very informative, since not much seem to be happening (at least to me). I’ve incorporated the debut logging, server-side, while –debug in the client shows the following: x2go-INFO-1> "Starting X2Go Client 4.1.2.1..." x2go-WARNING-1> English language requested, not loading translator. x2go-WARNING-1> English language requested, not loading translator.

Windows x2goclient and space in windows username
by Norman Gaywood 03 Mar '19

03 Mar '19

It seems now that if a windows user of x2goclient has a space in their username on their local windows system, x2goclient will logout immediately after logging in. This bug report I think is reporting this: https://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=1363 "Windows 10 version 1809 breaks X2go, can't read user name with space." I've had a few users experiencing this recently. Wondering if it's new or I've never noticed this. -- Norman Gaywood, Computer Systems Officer School of Science and Technology University of New England Armidale NSW 2351, Australia ngaywood(a)une.edu.au http://turing.une.edu.au/~ngaywood Phone: +61 (0)2 6773 2412 Mobile: +61 (0)4 7862 0062 Please avoid sending me Word or Power Point attachments.

Speed
by Robert Dinse 01 Mar '19

01 Mar '19

Was discussing how used to be able to watch videos on early x2go but not anymore. It was said to be a firefox issue. I found an interesting note in a vnc article but it might be applicable to x2go: On XFree86/Xorg it is actually possible to increase the framebuffer read speed considerably (10-100 times) by using the Shadow Framebuffer (a copy of the framebuffer is kept in main memory and this can be read much more quickly.) To do this one puts the line Option "ShadowFB" "true" in the Device section of the /etc/X11/XF86Config or /etc/X11/xorg.conf file. Note that this disables 2D acceleration at the physical display and so that might be unacceptable if one plays games, etc. on the machine's local display. Nevertheless this could be handy in some circumstances, e.g. if the slower speed while sitting at the physical display was acceptable (this seems to be true for most video cards these days.) Unfortunately it does not seem shadowfb can be turned on and off dynamically... Wonder if tweaking with this could benefit x2go response? -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

x2go and Ubuntu 18.04 server

Hi all, I'm trying to use x2go-server on a headless machine for virt-manager with x2go-client on Win10. I did not install any desktop environment. x2go terminates the connection immediately, no window is shown. If I use VcXsrv with putty, virt-manager is working fine. Here are some logs from the server: ==> auth.log <== Feb 28 10:27:14 ignite sshd[27502]: Accepted password for username from 10.8.20.10 port 62833 ssh2 Feb 28 10:27:14 ignite sshd[27502]: pam_unix(sshd:session): session opened for user username by (uid=0) Feb 28 10:27:14 ignite systemd-logind[709]: New session 24 of user username. ==> syslog <== Feb 28 10:27:14 ignite systemd[1]: Started Session 24 of user username.

Do I need to install a window manager on Ubuntu to run just a single apllication with x2go? Thanks!
