X2GoServer on New Ubuntu 15.04
by Robert Dinse 18 Oct '15

18 Oct '15

I just recently put together a new server based on an I7-6700k with Ubuntu 15.04 as the operating system. I am having some difficulties with the x2goserver 4.0.1.19-0~1064~ubuntu15.04.01. My client periodically tells me no response from the remote server and disconnects. I simultaneously have the same workstation with x2go clients connected to other servers, including other Ubuntu 15.04 servers, at the same location and they do not randomly disconnect. The server is not heavily loaded, the responsivenes is good. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Sound Ubuntu 15.04
by Robert Dinse 06 Oct '15

06 Oct '15

The sound problems with X2Go with a Ubuntu 15.04 server turned out to be kernel related. The 3.19.0-30 kernel is problematic for some reason. I installed 4.2.3 and sound works now. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Start Up Scripts Not Being Sourced
by Robert Dinse 05 Oct '15

05 Oct '15

If I connect using NX plugin with Remmina to freenx-server, /etc/profile and related start up scripts all get sourced properly. If I do the same with x2go they do not on some platforms, for example it seems to work on old Centos but not Fedora or Debian derivatives, and I end up with an environment not properly setup. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Warning message about a Xubuntu dist-upgrade
by "BOTZ Franck (Administrateur Systèmes et Résea ux) - DDT 67/SIDSIC/Pôle Infra" 05 Oct '15

05 Oct '15

Hi !! So, i have a curious issue with a system update. I've done a snapshot from my X2Go server wich work on a Xubuntu 14.04 64 bits system at 24/09/2015. Everyting works great on it : Firefox, Thunderbird, Qgis, Libreoffice. Friday 02/10/2015 i've done a dist-upgrade on Xubuntu. A new kernel (65) comes. After that, I've got a i/o error on Firefox, Thunderbird, and Qgis opened but menus don't work. Libreoffice seems to be good. When I restore the snapshot, no problem appear. So next step is to identify the origin of this issue. When I launch an apt-get upgrade, the problems appear again.

Unable to connect to Fedora 21 xfce from Windows
by Joseph L. Casale 04 Oct '15

04 Oct '15

When trying to connect from a Windows 10x64 desktop with the current release and 4.0.5.1 to a Fedora 21x64 xfce workstation running versions: [root@localhost log]# rpm -qa |grep nx nx-libs-3.5.0.31-1.fc21.x86_64 nxagent-3.5.0.31-1.fc21.x86_64 [root@localhost log]# rpm -qa |grep x2go x2goagent-3.5.0.31-1.fc21.x86_64 x2goserver-xsession-4.0.1.19-3.fc21.x86_64 x2goserver-4.0.1.19-3.fc21.x86_64 I get disconnected immediately after initiating a connection with the following in the session file: Loop: PANIC! The remote NX proxy closed the connection. Loop: PANIC! Failure negotiating the session in stage '7'. Loop: PANIC! Wrong version or invalid session authentication cookie. The versions are higher than the releases in bug 406 and 504 so I am not sure what else could be the issue. Is this specific to Windows 8.1 and 10 as they both exhibit the same behavior. The key is correct and using a password doesn't help either. Thanks, jlc

Massive beginner's woes
by Brian Capouch 04 Oct '15

04 Oct '15

I have been trying--without success--to get x2go running, Linux server and Linux client. I tried on my local machines here both Slackware. I have 4.0.1.5 server-side, and the client is 4.0.5.0. and then thought, well maybe I'll be better off with a packaged system, so I spun up a Debian system in the cloud, and used apt-get to install everything. There the server is version 4.0.1.19. I am trying to run the client on a remote machine. Does an X server already have to be running on the physical machine to use x2go? Do I want to be running in Desktop, Rootless, or Shadow mode, and how does one even select such a thing? I am really motivated, but the complexity of the system combined with the limited documentation (e.g. I see there are two x2gostartagent processes running, caused by my ssh connection to the server machine. What should happen next?) may mean that my hopes of using x2go may be dashed. How much does "professional help" run? All the sites linked to the main page are in German. . . Thanks, and sorry this is so long. b.

Make an x2go connexion without the gui

Hi, I need a complet x2go no-gui connexion I have tried using x2go --thinclient. I'm able to connect using profiles, but I notice that each time I call x2go, I open a new instance, what I don't want, and I'm not able for now to recall the already opened instance. I have tried pyhoca-cli, but I'm now not able to connect to a machine.

In x2goclient Session Management
by Robert Dinse 03 Oct '15

03 Oct '15

If you bring up the x2go client session manager and then click on a particular session, Delete is grayed out and one can no longer delete a session. I couldn't find an alternative method in the client and just hand edited the x2goclient/sessions file, but I can't believe this was the intent. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Switching between Desktops
by Robert Dinse 03 Oct '15

03 Oct '15

I had commented earlier about the behavior of X2Go verses NX when it came to switching Desktops when in a session. That X2Go would pass the CTRL + ALT + -> and CTRL + ALT + <- keys to the remote application rather than allowing the local switching of desktops with those keystrokes. It was suggested editing keymaps, but actually the solution turned out to be much simpler. When you create a session you can specify a full screen, a window of some size, or the whole display. If you specify a full screen those keys are passed to the remote and you can't switch desktops locally except by doing CTRL + ALT + M to minimize the x2go session and then switching desktops. And that's a pain if you are working on a bunch of servers and have to switch frequently as if often the case for me. However, if you specify use the whole display rather than full screen then the ALT + CTRL + -> and ALT + CTRL + <- arrows are acted upon locally allowing the easy switching between local desktops (with X2Go sessions to various servers). What would be very nice is if there were a way to switch that setting on the fly. With the Remmina NX client, you have a little one-pixel pull down at the top of the screen, and if you pull it down there is a keyboard symbol. If you push the symbol it visually depresses, then all your keystrokes go to the remote computer, if you undepress it, the CTRL+ALT+ arrow keys are acted upon locally. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Sound Troubleshooting
by Robert Dinse 03 Oct '15

03 Oct '15

I just installed Ubuntu-Mate 15.04 on a new server, installed pretty much all the x2go packages, but for some reason sound does not work over x2go on this machine. The same client receives sound fine on another server with Ubuntu-Mate 15.04. Both have the same version of x2goserver, 4.0.1.19-0~1064~ubuntu15.04.1. One significant difference is the server that works started life as an earlier version of Ubuntu, 14.04 I think and then was upgraded to 14.10 and then 15.04 in place where as the new server was installed from a Ubuntu-Mate 15.04 DVD made from the ISO that is available on ubuntu-mate.org. Any suggestions as to where to start troubleshooting the server? -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.
