x2go and vnc interconnection
by x2go＠karel.tt.ee 03 Apr '12

03 Apr '12

Hello! I am new x2go user. I have one virtual Ubuntu installation (12.04, Gnome) where I have set up x2go server running and I can connect remotly (from other linux or windows desktop systems), have working audio etc, and all this is independent. But also I would like to use any kind of vnc as backup in case where it is not possible to install/use x2go client (ofcourse it is slower, no audio etc) to get and use the same already running x2go session. The best I can with x11vnc is original desktop of this virtual installation but where is nobody logged in most of time. Or with vnc4server I can get a new independent desktop (third one). Does anyone tried and got success in such combination of vnc and x2go virtual sessions? There is also desktop sharing feature in Gnome menu and once activated I can get exactly what I want, but this vnc connection will almost freeze (no more than 2 actions can be done in one minute) after I disconnect my x2go client. Everything is running again after x2go client is reconnected. Yes, I understand, this is vnc related as well as x2go question but...

long delays on Eclipse redisplay
by Dan Halbert 02 Apr '12

02 Apr '12

I'm using x2go Windows client 3.99.2.0-rc2 and also the Ubuntu client, connecting to Ubuntu 64-bit x2go version 2:3.5.0.12-0~234~oneiric1, using both gnome-session-fallback and unity-2d sessions. With certain client programs, especially Eclipse, I have noticed a very long delay when a redisplay of the underlying program window is necessary. For instance, when a dialog box that overlaps the main Eclipse window is closed, or a terminal window is put underneath Eclipse, there can sometimes be a 5-30 second delay before Eclipse redraws itself. During that time the whole x2go session is frozen. I looked in all the relevant logs and see nothing. I am not sure this is an x2go problem at all, but I don't remember similar problems with Eclipse and freenx. I've looked for similar Eclipse bugs, but all the ones I found that sounds similar are quite old and supposedly have been fixed. If you have seen this problem with Eclipse or other client programs, I'd be interested to hear about it and if you have a fix. Thanks, Dan

tce how does --haltbt work
by Stefan 01 Apr '12

01 Apr '12

Hi all, I still try to build a local thinclient environment for laptops using an window manager. This is necessary because I need a graphical interface for network (wicd) and an power-manager (gnome-power-manager). The x2goclient shall be work as an login-manager as transparent as possible - nearly like on the thinclient environment. While I got usb automount running, I still try to get halt button inside the x2goclient working. When I start the x2goclient with the --haltbt option I got the button inside the x2goclient, but without function. Can anybody help me please in understanding the procedure this is working in the thinclient environment? Which is the command the client sends and what I have to configure? Thanks and greetings stefan

x2goserver on vserver guest
by Adèlphe Rafanambinana 31 Mar '12

31 Mar '12

Hi all, I'm using x2go on Ubuntu, and it works well. Starting this week, I'd like to install it on Alpine Linux ( www.alpinelinux.org) which is installed inside a vserver. (There is an x2goserver package for Alpine Linux in edge repository). x2goserver and its dependencies are installed correctly. But when I try to run x2goclient which is installed on my windows desktop, I got the attached error. Do you have an idea for it? I was wondering if it could be related to fuse module, since it coulodn't loaded in vserver guest. Any comments are welcome!, Thank you, Adèlphe Rafanambinana

X2Go on wheezy Xen DomU
by Mirco Schmidt 29 Mar '12

29 Mar '12

Hi all, this is my first Msg to the list. I've setup x2go on one of my DomU's, it's running wheezy with the latest update's. I can connect to KDE, but can't to LXDE and GNOME. But that's not the main prob… I can't continue session's, all I see is a greyed continue button. Client is running on Mac OS X 10.7.3 with modified lib's from a NX… Hope you can gi'me a hand to find a solution! Greetz Mirco

Do you happen to remember what was the latest version before the libssh move? I'll gladly check if there's an old build laying around somewhere. Sent from my ASUS Eee Pad "John A.

Re: [X2Go-User] x2go Rocks! - just think of next steps...
by brian mullan 29 Mar '12

nigra... now that you have x2go working. Here is something else to add to the mix. you want a "cloud" desktop but it has to support linux & windows. in the cloud (I use aws's ec2) create a linux desktop server. (I use ubuntu) I create an ubuntu server instance on AWS's EC2 cloud by: - ssh into the instance - install a default ubuntu desktop (apt-get install ubuntu-desktop) - add the x2go ppa sudo add-apt-repository ppa:x2go/stable - refresh the repository cache (debian/ubuntu) sudo apt-get update - install x2go server sudo apt-get install x2goserver - add yourself to the x2gouser group sudo adduser <yourID> x2gouser after that ... you should be able to go back to your local machine and start your x2goclient and point it to your AWS EC2 cloud PUBLIC IP address and get to logged-in. BUT... what if you want Windows apps too.. On the "cloud" x2goserver think about setting up FreeRDP (http://www.freerdp.com/) In whatever "cloud" you use... start a Windows 2008 v2 server. - On that Windows server as Admin ... - install and setup whatever RemoteApp applications you want - and publish them <http://www.youtube.com/watch?v=Nf20-76dMcg>. (demo'd at UDS in Orlando http://www.youtube.com/watch?v=Qnh7f36xkRA and I've done it locally myself to aws servers) Back on your Linux/Ubuntu machine use FreeRDP to execute the Windows "RemoteApp" application. Big picture... - you are on a remote pc/laptop/tablet etc running an x2goclient - you connect to your "cloud" x2goserver machine and login - your login has a menu or some desktop icons that when clicked - uses FreeRDP to execute the Windows Apps off of the Windows "cloud" server as just another xwindow. - That uses the RDP protocal. But since its all "intra-cloud" between instances (the windows cloud instance and the linux/ubuntu cloud instance) - the I/O is very high bandwidth (on AWS it would be 1-10Gbps) links. - Now since you (the x2go client) are remotely connected to the "cloud" linux/ubuntu server and utilizing the great compression of x2go/nx - the remote windows & linux apps "appear" to have the same good performance. Lastly, because freerdp lets the windows apps appear as just "any other" linux app the end user only has one "look-and-feel" etc to deal with which can be a big issue in end-user training and acceptance with just a single desktop & user interface.

Hi, I just wanted to say thank you for the great thing that X2Go has become. I use it on a daily basis on several systems and could not think how I would work anymore without it. It provides a functionality that I have looked for so many years, but could never find. I always thought that a Linux server would be perfect to be used as a terminal server, but was always amazed and confused at the total lack of any application that provided this functionality. Then, Windows RDP came along and I did not understand how Linux with X and that network-ability of it failed to provide something similar. And finally, we got it! I hope that X2Go will find it's way into all Linux Distros. I wish there was a CentOS and RedHat package so I could load it onto each customers machine that I have to support, instead of having to use sucky VNC or putty or be limited to using a remote shell, instead of the rich GUI experience that KDE and Gnome can offer.

Composite extension
by Ralph Sikau 29 Mar '12

29 Mar '12

Hi, we connect to a gnome session on a x2go host. This gnome session has cairo-dock installed which unfortunately cannot make use of the composite function included in metacity for real transparency. When I start xcompmgr it says "no composite extension". The x2go windows client uses vcxsrv which is supposed to be even opengl capable. Where is the handicap here? Best, Ralph

x2go server & client on Ubuntu 12.04 beta fails
by brian mullan 29 Mar '12

29 Mar '12

I have not been able to get x2go server/client to work on Ubuntu 12.04 client/server machines. I installed the x2go ppa for ubuntu sudo add-apt-repository ppa:x2go/stable I installed on the server the x2goserver: sudo apt-get install x2goserver on the client I installed the x2goclient: sudo apt-get install x2goclient On ubuntu 12.04 I have installed the 'fallback' gnome desktop support but in previous versions both Unity or gnome worked. Now when attempting to start an x2go client session (see below): ssh connection gets established public/private keypair are generated search for proxy starts session aborts/terminates Anyone got any ideas what the problem might be or how I can troubleshoot further?
