You can test this for example with audaciuos (has a pulseaudio output plugin). Furthermore you've need to make sure, that the local (client side) pulseaudio device can be used and the local user has the rights to use it. You can test this, by using a local installed application. The server side flashplayer needs to be configured to use pulseaudio - this is not a preconfigured feature.

We are working on a new implementation of pulseaudio which will start an own instance for every user. This will be part of a new release which will include a input field for the client dpi value too.

Thinclient doesn't work any more
by Sven Strickroth 27 Nov '09

27 Nov '09

Hi, after the package update the thinclient doesn't work any more. It boots up correctly and displays the X2GoClient-Login. But when I enter any credentials and press "OK" a white box appears (for a few milli seconds) and then I'm back to the login screen. How can I fix this? Best regards, Sven

Single client multiple silmultaneous server connections...
by Douglas Stanley 26 Nov '09

26 Nov '09

I've been running into some trouble and it seems like this is not possible. I'm using x2goserver on multiple servers (one at home, one at work) and it doesn't seem to be possible to connect to both at the same time. Is there a work around to allow this, or do I have to suspend one and resume the other all the time? The problem seems to be when the reverse ssh connection is set up. It always seems to use the same port (perhaps dependant on the remote display number, which is 50 on both machines I'm connecting to since I'm the only user). I apologize if this was already discussed on the list, but I couldn't find any info in the archives. Thanks, Doug

x2go in bestehende LDAP Installation einbinden
by Sven Winkelmann 20 Nov '09

20 Nov '09

Moin ich hab es inzwischen geschafft das x1go läuft und auch das alle Einträge im LDAP vorhanden sind, so das der x2goclient nicht meckert. aber ich würde gerne wissen, wie ich per ldiff neue Server unter ou=server,ou=ON,... hinzufüge. da die kde tools ja leider unter kde4 den dienst verweigern und ich eh kein freund von kde bin ;)

Hi Admins, this is my first post here. It is not possible to login. If I start the session and enter my password, the desktop remains blue with two images in the bottom corners. In the message box of Xwing appears, "There are currently 0 clients connected. Thanks for your help. Cheers --

X2go and Debian Etch
by Paul van der Vlis 10 Nov '09

10 Nov '09

Hello, I have installed x2goserver on a Debian Etch machine and I added myself to the x2gousers group. But I cannot get contact from a client on Debian Lenny. I don't see an error. Is it possible to connect from a new client to a X2goserver on Debian Etch? Is it possible to install the X2go version for Lenny on Etch? With regards, Paul van der Vlis.

I think this is a pulseaudio related thing. If you use Pulseaudio, you need to make sure, that the remote aapplications use pulseaudio as audio output. You can test this for example with audaciuos (has a pulseaudio output plugin). Furthermore you've need to make sure, that the local (client side) pulseaudio device can be used and the local user has the rights to use it. You can test this, by using a local installed application. The server side flashplayer needs to be configured to use pulseaudio - this is not a preconfigured feature.

Even more so bacause it doesn't seem to be sponsored by a big company. Good work! Thank you! > I'm about to set up a lan with a single server and 15 clients in a nursing home for older and mentaly ill people and I have a few questions. It's not development related, but since there is no other mailing list, i'll post it here. No Problem - we've decided to keep everyting here on one place. > 1. Hardware requirements for the clients: I haven't found anything on the site or in the docs, except in the "linux pro magazine" article where it says: > > This said, the Qt engineâs SVG renderer > will take 5 seconds to display the > login manager under these circumstances. > > So, if 800 MHz is not enough, what would be enough? What about RAM? It is not easy to define real limits. The Nokia N810 for example has a CPU (arm) with 400Mhz and is working perfectly. But I've seen to a Via Thin Client with 1 GHZ performing really poor because of it's GPU. If you use the GTK Client, you won't need time to render SVG, but I don't think it is a real problem, if the initial display with the user information would take 4-5 seconds. More important would be, if the local device has enough power to encode and display the remote screen. Because I don't have a hardware DB with user experiences linked to devices, I only can say - please test your device. Paul has already answered so thank you Paul! > 2. Hardware requirements for the server: any advice concerning cpu and RAM for 15 clients, running, say, KDE (pretty basic, without most of the bells and whistles), firefox and openoffice? KDE has a very small footprint, but OOo and FF can really stress a server - especially if you use flash. The number of instances will be mainly limited by your RAM. You can ignore the needed ressources for the terminal server and only count the numbers of application instances. A typical setup would be 25 users on a Dualcore/8GB system, but again - the result will be based on your applications and document sizes. > 3. I'd like to use diskless clients which get their boot environmnet and their kernel from the server at boot time and using x2go as the display manager. Do I have to install the regular x2go server or would the x2go server ONE be enough? We've only described the Installation with LDAP but you also can use x2goserver-one for the boot environment. The diffference would be, that you won't have a user browser. > 4. And finally, how stable is x2go? Do you guys use it in a production environment? I have no problem filing a bug report here and there for minor things in a project like this, but those shouldn't be serious issues. If bad things happen in any significant frequency, I'd have to use nomachines nx, although I am an open source fan and would rather use x2go. X2go is used in bigger schools (1200 students) in enterprises and companies. Some of them are using a supporting company for help. Linux4afrika and Linux4paraguy are supporting a lot of schools - some even in germany. > Thanks for reading this lengthy post. I hope you find the time to answer some (or all) of my questions.

Re: [X2go-dev] General question`s

Hi, I have had some time to test a bit around with the sound issue`s I had. After I have filled in what`s described here http://www.pro-linux.de/berichte/x2go-ubuntu.html at the end of the Page. It works now with the x2goclient for Windows. They are able to use the sound. When I try to connect from a Debian Machine for example it won`t work. I have no idea why but if Im trying to log in as the same user from a Windows client it works fine. At least a bit oft it ;). YouTube and other video platforms won`t work. I think this is a pulseaudio related thing. Unfortunately Videos are too slow. Would it help to install the commercial Graphics driver from ATI for instance on the server? Or are there any other possibilities to speed things a bit up? Greetings -- GRATIS für alle GMX-Mitglieder: Die maxdome Movie-FLAT! Jetzt freischalten unter http://portal.gmx.net/de/go/maxdome01
