Re: [X2go-User] Mac client 'Can't connect to X-Server
by Neil Hunt 14 Nov '12

14 Nov '12

Paul, Unfortunately as a regular user of the Mac X2go client, this is something I've seen many times. Unfortunately, I haven't found any fix for it. The good news is that it rarely happens if you keep the X11 application open. Always open X11 before starting your X2go session. From there, you can stop/start X2go sessions, even the X2go client itself, however I almost always keep my X11 app running even when it's not being uses and then I don't get the problem you are describing. If I quit X11, especially if it's accidental during an active X2go session, then I end up with the problem you are describing and the only option is to restart the whole computer. But if I keep it open, I go for days or weeks without rebooting. Ultimately, I think we should look to move to the PyHoca gui, but we haven't been able to find any serious python developers to port it to OS X. Neil -------------------------------------------------------------------------------------------- Date: Wed, 6 Jul 2011 12:14:51 -0700 From: Paul Northug <pnorthug(a)gmail.com> To: x2go-user(a)lists.berlios.de Subject: [X2go-User] Mac client 'Can't connect to X-Server' Message-ID: <CAJAeRZy=KmQsVyoELQ4MrTDHZ8g03x8tXJm_hTL5NK50jQ9QEw(a)mail.gmail.com> Content-Type: text/plain; charset=ISO-8859-1 Thank you to the developers for make this excellent software. Many people at my work use x2go's Mac client. We have never been able to figure out how to resolve the 'Can't connect to X-Server' error without random acts (eg. rebooting). We are not sure why it comes up. This is what I do: 1. Start X11.app 2. ssh -X remotehost 3. xterm & So far this works, I get an xterm so there is nothing wrong with X11 4. Start X2Go client 5. Start a session (port 22, dsa authentication, Gnome...) 6. Client gives the error and hangs (Abort and Terminate don't do anything) and I have to close the application. The closest we got to figuring it out is that the X11.app possibly changes it's DISPLAY on restarts and perhaps the x2go client is expecting display 0. Is there any more debugging information that I could get from the client to see what exactly it is doing prior to giving the error message? We have tried some of the suggestions in the forums, such as changing permissions in X11.app (this is necessary), starting it manually before starting the client. We have also done things like messed with firewall settings, made sure hostname doesn't change on our laptops between work and home, deleted preference files, delete XAuthority files, etc. What seems to work is rebooting. Thanks, P?l

Sound issues in new release
by Frank Schlingmann 14 Feb '12

14 Feb '12

Dear all, I hope this is the right place for my problem as I have started with x2go only e few weeks ago and could not find many resources. I did a test two weeks ago and sound was working well. Now I made a new installation and encountered two problems compared to my last installation: - when I login remotely there is now start-sound - when I use flash (e.g. browser) I can only hear sound in the left speaker. My client is a WinXP and the server is running ubuntu 11.10 in a virtual box. In my first test (two weeks ago) I heard the start-sound when I logged in remotely. I am not quite sure about stereo but I think both channels worked also. Now I made a fresh install of x2go on the server today and faced the problems mentioned above. I made an upgrade on the client from 3.99.0.3 to 3.99.0.4 with no changes, the problems persist. Did I miss something? Any help is appreciated. Frank

Dear all, The Debian X2Go Packaging Team and the X2Go Project proudly announce that x2goclient has entered Debian unstable. http://qa.debian.org/developer.php?login=pkg-x2go-devel%40lists.alioth.debi… Package compatibility is currently tested by Ubuntu developers and we hope to get x2goclient (and nx-libs-lite) into Ubuntu 12.04. The chances are good that this will work out.

Connection fails when connecting windows client
by christoffer krakou 26 Jan '12

26 Jan '12

Hello X2go-people I have a Ubuntu 11.10 server running X2go. From my own ubuntu i can connect fine with the 3.0.99.04 client from the PPA archive. The server's version is 3.0.99.9. When a Windows client connects (v. 3.0.99.4) to my server, the client program seems to hang at "connecting". On the server, a process called x2gostartsession goes completely nuts and takes up all the system resources. The session is owned by the user trying to log in. What can this be caused by? -- Venlig Hilsen / Best Regards Christoffer Krakou Fleten.net APS
