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

Autolaunching

I can't find this in any of the docs, wiki, or man page. I want to set up a KDE menu entry to launch x2go sessions automatically. This should involve a command-line something like 'x2goclient Droog' (with Droog being the session I've created), but that doesn't work. # man x2goclient No manual entry for x2goclient See 'man 7 undocumented' for help when manual pages are not available. # x2goclient -h Can't load translator (:/x2goclient_en_us) ! Can't load translator (:/qt_en_US) ! wrong parameter: -h Otherwise, GREAT JOB on x2go peoples! Thank you!

x2goclient X-forwarding-problem
by Stefan 10 Aug '11

10 Aug '11

Hi all, I've the following setup: * a remote Xserver-session on a client via xdmcp and gdm3. * In this session I want to use x2goclient to access a remote server Starting a X2go-session with x2goclient I get the following error: ... ... Info: No suitable cache file found. Info: Forwarding X11 connections to display '192.168.0.50:0.0'. Session: Session started at 'Thu Jul 14 12:12:50 2011'. Warning: X connection failed with error 'Invalid MIT-MAGIC-COOKIE-1 key'. Session: Session started at 'Thu Jul 14 12:12:16 2011'. Warning: X connection failed with error 'Invalid MIT-MAGIC-COOKIE-1 key'. Obviously there is a problem with the access to the xserver. Using kdm (kde4) instead of gdm3 it works (partly). Maybe the difference is, that gdm3 doesn't use ~/.Xauthority any more. See here: http://bugs.debian.org/cgi- bin/bugreport.cgi?bug=586685 Maybe the proposed workaround helps here. I'll try. regards stefan

x2gousers is missing?
by Patrick Willam 30 Jul '11

30 Jul '11

Hi all! :-D <blah> Recently i'm taking my time to get my Personal Computers in a more useable and productive state. A very important part of this process/project is getting X2go to run on my systems. </blah> After installing X2go on my main machine (details: see below) i wanted to use it, of course. But when trying to start a session via x2goclient i get no further than while connecting an error dialog appears with this messeage: "Please install this program as SUID x2gouser!" So i thought: maybe there is an issue with the installation process of the packets, and some rights have to be adjusted manually afterwards. But the problem seems to be that a file called "x2gouser" is missing at all!? $> dpkg -L x2goagent x2goclient x2goserver x2goserver-extension \ | grep x2gouser ...gives nothing. Any help/hints on this is very much appreciated. Best wishes, happy hacking and greetings to Treuchtlingen & Kiel! Patrick ps: I `frankensteined´ the "perl-suid" package from "squeeze" using "Depends: perl (>= 5.10.1), libc6 (>= 2.4), libperl5.10 | libperl5.12 | libperl5.14" and installed this manually to get "x2goserver" installed on wheezy/sid.

x2go Mac OS X Lion 10.7
by Neil Hunt 29 Jul '11

29 Jul '11

Bad news to x2go users who have reliance on a mac client. I upgraded to Lion, which has finally left Rosetta/PowerPC emulation in the dust since Apple has begun moving away from it six years ago, and when I went to connect to my x2go server, I immediately get the error: "You can't open the application nxproxy because PowerPC applications are no longer supported." NoMachine NX 3.5 runs strictly on PowerPC and Rosetta emulation and thus is no longer compatible with Lion. NX4 runs on Intel natively and will run on 10.7 Lion. There is the OpenNX client for Mac which I've tested on Lion and connects to my FreeNX server no problem. So the nxproxy library must somewhere be ported to Intel-based Lion architecture? Please advise, we have quite a few users who use x2go mac client and I need to have a support plan for Lion migrations. Thanks, Neil

x2goclient version bumping -> 3.99.0.0
by Mike Gabriel 22 Jul '11

22 Jul '11

Hi devs, today I had a chat with Alex about x2goclient, the versioning, the next major version (Baikal) of x2goclient, etc. o we have bumped the version to 3.99.0.0 in Git o the next major stable release will be 4.0.0.0 (x2goclient/Baikal) o Oleksandr will build a Windows x2goclient with that same version number Packages for Debian are building currently, they will enter the nightly builds repos as well as the ,,main'' repos. Please go ahead and test these new versions, please. Report issues to the x2go-dev mailing list, so that we get as many issues fixed before calling the thing 4.0.0.0.

core dev-team testing x2goclient during next week
by Mike Gabriel 22 Jul '11

22 Jul '11

Hi all, thanks to everyone (esp. to John) for taking such a meticulous look at the latest x2goclient 3.99.0.0 (Win32 version). There obviously seem to be quite some open issues that we have to cross-check on our own development/testing systems. Alex (the core developer of x2goclient) will do that ASAP, we hope to come up with some feedback, patches, comments by the end of next week. If that gets delayed, I will let you know about the delay and come up with another timeline. Unfortunately, as X2go is not a commercial project, this cannot be any quicker. We apologize for this!!! If there are people out there you can read/write C code, please feel free to clone git://code.x2go.org/x2goclient.git and cross-read the code. Some other problems, however, may arise from x2goagent, as well. So you might use git://code.x2go.org/x2goagent.git for lecture as well...

RDP packing
by John A. Sullivan III 21 Jul '11

21 Jul '11

Hello, all. We are still trying to address the very poor performance of rdesktop sessions transmitted over NX - much slower than native RDP although we were expecting it to be much faster. In reading the NX documentation, we saw that they have a packing algorithm especially for RDP. However, whenever we enable this packing algorithm, the session aborts. Has anyone successfully used it? How do we troubleshoot this issue? Thanks - John
