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

Hardware Requirements, Stability
by Peter.Seckler＠gmx.net 03 Nov '09

03 Nov '09

Hi everyone, first, I have to say, I am really impressed of what I read about x2go and its features. Even more so bacause it doesn't seem to be sponsored by a big company. Good work! 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. 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: The current X2Go system requirements include a display of 640x800 or more and a client machine with an 800MHz CPU. This said, the Qt engine’s 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? 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? 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? 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. Thanks for reading this lengthy post.

Remote sound/remote USB device access
by Michael Hierweck 02 Nov '09

02 Nov '09

Hi x2go folks, first of all - is there a user mailinglist available? If have just successfully setup x2go on a Debian Lenny based server and a set of diskless remote booting thin clients. (I talked about "hacking" Debian's boot process merging a read-only nfs filesystem and tmpfs in order to easily remote boot x2go clients some months ago.) Nevertheless remote sound and remote USB device access refuses to work. Is there a piece of documentation/howto on this topic? E.g. does pulseaudio has to be installed, enabled as daemon on the server/client side? Howto test, debug...? Do remote sound/USB device access require any configuration on the server/client side? Thanks in advance Michael

But first I have to get sound working. I have tried it yesterday with the GTK X2goclient but Gnome won´t play any sound at all. It just says that there is no Audio device in my machine and that´s it. Do I have to install pulseaudio or any other Packages manually? Greetings -- GRATIS für alle GMX-Mitglieder: Die maxdome Movie-FLAT! Jetzt freischalten unter http://portal.gmx.net/de/go/maxdome01

x2go test
by kamerun＠immerda.ch 02 Nov '09

02 Nov '09

hello, we are testing x2go. we made an installation with debian lenny with xen and an x2goserver as virtual machine without ldap. (with ldap it was never working) it works but the sound is not going. what are the conceptual differences between NX and X2GO concerning the treatement of local device, for example audio card. another problem: in LTSP we have a file lts.conf, where the client can be separetely configured, exist such a file in x2go? we just test test the x2goserver-one as package in a xen virtual machine the client will not start, it says Connection failed 192.168.1.86: cat: /home/a/.x2go/C-a-50-1256917694_stDGNOME_dp32/cmdoutput: No such file or directory i control on the server, this file does not exist. test of x2goserver-home on ubuntu machine ubuntu 9.10 (not as xen virtual machine) client works fine. paul michel
