Error: "Failed to restore all the required visuals"
by Colin E 05 Nov '14

05 Nov '14

*Server: Debian "Jessie" X2Go Server: 4.0.1.18-0x2go1+git20141006.949+wheezy.main.1 Client: Windows 7 Pro 64 bit X2Go Client: 4.0.3.0 (Qt - 4.8.6)* Hi, I am using X2Go to access a headless Debian (Jessie) machine from Windows 7. At some time in the last couple of days I must have closed or aborted the connection from the client without cleanly shutting down the server session. Now when I try to open a session to the machine I get the error- *Failed to restore all the required visuals Can't resume the NX session on this display* I can see XFCE session and a bunch of other X services running on the server. I can of course just log into the server using SSH and kill all the X processes (or reboot the machine) but that will lose any work in windows that are still open on the server. Is X2Go able to reconnect to an existing server session? If not is there a better way to clean things up than just killing server processes? Regards *Colin E *

Local printing fails with Windows client
by David Zafra [KLO] 03 Nov '14

03 Nov '14

Hi everybody We have installed X2Go server and it works fine. When connecting from Linux client everything works fine, remote printing too. But when we try to use remote printing from Windows (XP and 7) client it doesn't work. No error messages shown. Write printing document as a PDF file does work. Here I list server versions * cups-x2go: 3.0.1.0 * x2goagent: 3.5.0.27 * x2golxdebindings: 1.0.2.2 * x2goserver: 4.0.1.15 * x2goserver-extensions: 4.0.1.15 * x2goserver-printing: 4.0.1.15 * x2goserver-xsession: 4.0.1.15 Windows 7 client uses 4.0.2.1 build 4. I would thank so much any help. We are in a hurry! Regards, -- *David Zafra Gómez* KLO Ingeniería Informática ~~--.. www.klo.es <http://www.klo.es/> ..--~~

Usage question - multiple destination sessions?
by Cohen, Neil 30 Oct '14

30 Oct '14

I have x2go configured on a mac system and I use it to connect to a remote Linux system. Works fine. However, I would like to be able to open a second session on a different Linux system. Is this possible? Right now, it appears that everything hangs when I do that. I’m guessing there are ports that are being reused – probably for the display, but I don’t know anything about x2go configuration files…. If this isn’t possible, is there some way to get multiple, simultaneous access to different remote systems using x2go?

Many documentation bugs / old options have been corrected / removed from the man page. @Alex: can you please proof-read the new man page [1] and give feedback / commit fixes? THANKS!

I have seen this once or twice, but it was not reproducible. What are your settings for SSH authentication in the session profile configuration? Can you make a screenshot? Is ssh-agent running and have you loaded your SSH private keys into ssh-agent? Or does pyhoca-gui try to detect some default private key file in ~/.ssh? What hostkey types are configured on the X2Go Server (check /etc/ssh/sshd_config, HostKey parameter).

Packer script and public x2go AMI
by Nick Owen 28 Oct '14

28 Oct '14

Greetings. I recently wrote a tutorial on x2go and have been playing with it some more. I've also started implementing my tutorials as packer scripts. Packer.io is a pretty cool tool that builds various virtual images (amis, vbox, vmware, GCE etc). It allows provisioning via scripts/chef/puppet etc. Anyway, my scripts to create an X2Go server are here: https://github.com/wikidsystems/packer_templates/tree/master/x2go. The AMI is public. It is ami-c854d7a0. Pam-radius is not configured out of the box, you need to do some editing in /etc/pam.d/ssh and /etc/raddb/server for it to work. But with the ami, you can 1. log in as root 2. add a user and have them log in with the x2go client. So, an easy way to play with x2go.

client side printing
by Bernhard J. Mayr 27 Oct '14

27 Oct '14

I am having big trouble administering client side print functionality. I have installed the x2go print package on the server. The user is in the fuse group and there is a spool-dir mounted. In the X2Go Client I configured client side printing. bmayr@127.0.0.1:/home/bmayr/.x2go/S-root-50-1413989095_stDLXDE_dp24/spool on /tmp/.x2go-root/spool/C-root-50-1413989095_stDLXDE_dp24 type fuse.sshfs (rw,nosuid,nodev,default_permissions) When I start a print job, nothing happens. The cups-access log says: localhost - - [22/Oct/2014:17:03:01 +0200] "POST /printers/Virtual_X2Go_Printer HTTP/1.1" 200 21992 Print-Job successful-ok Any ideas what I can do to enable client side printing?
