Hi
What I can contribute is that I have been using X2go for more than 6 months now and very successfully. I run the server on Debian Squeeze (and Lenny before) and connect to it from Windows 7 and Ubuntu 10.04 and Debian Squeeze (Laptops). So far I have had some issues, but it is very stable. So stable in fact that I am often working remotely on my server at home (connect over the internet via SSH). Resuming works almost always and I have to say, I am surprised how well it works. I would like to extend my congratulations and thanks for this nice piece of software to you developers! I have used Nxserver and NXfree (or freenx, I always confuse them) and that used to work much worse, with suspending and resuming spotty at best.
(I have to admit that this does not comment the commercial version of NXserver, which must be much better I am sure)
It is unfortunate that you have having so much trouble getting it to work, I can relate to this, as your question indicates, like "is this working ANYWHERE?" and yes it does, very well. So I am sure there must be some way that you can get it to work. But when it comes to open source, yes, the documentation can be lacking and sometimes it takes a long time and strains the patience. What I can say is that it is worth the work, since the software works very nice and I am glad that finally I can use my server at home as the unlimited (no more 2 or 3 user limit) terminal server that I have always wanted. Even audio forwarding works (on Windows, so I can hear the pulseaudio on my server session, EVEN THOUGH I have Jackd audio deamon running on it. How this can work is beyond me, a positive surprise to be sure. And filesharing works also.
I also understand and write German, but I understand that this mailing list should be kept in English, so I hope you can understand me. I know that my configuration is kinda simplified, as I am not using LDAP or any kind of complex user authentication mechanism. It might be easier to get it working simple, before trying to tacke these. The repository that I am using currently are these, just in case this helps:
deb http://x2go.obviously-nice.de/deb/ lenny main
(I actually went to my open terminal session window and copy pasted it (even this works))
As you see, I am still using the lenny repository (in case there is a newer one) and use the server
and here are the packages that I have currently installed:
pinentry-x2go install pinentry-x2go-gtk install x2goagent install x2gocdmanager install x2goclient install x2goclient-cli install x2goclient-gtk install x2gokdebindings install x2goserver install x2goserver-home install x2goserver-one install x2gospyglass install x2gousbmount install
Just in case this helps...
as you can see I am using the x2goserver-home or one version which is simplified without all the bells of whistles of authentication, if I understand it correctly.
I remember one issue that I had was about Xming not running in Windows (which is the component that acts as Xserver). In my case it was not started automatically.
Another thing is my /etc/sudoers config
### X2GO section %x2gousers ALL=(ALL) NOPASSWD: /usr/bin/x2gopgwrapper
#### X2GOPRINT section x2goprint ALL=(ALL) NOPASSWD: /usr/bin/x2goprint
And I remember having an issue with that.
These settings might be too insecure for your taste, but it is easiest to first open things up and circle the problem wide, to see where it is located at.
Hope this helps..
