I have a gotten a lot of feedback, that normally a session can be faster started and resumed - but x2go has an completly different handshake. A used compinent can be responsible for the delay. What you really should check, is that the name resolution is working. You should be able to connect to the server over SSH without delay. > There is also a windows 2003 running there where rdp is running extremely > smooth with about 3 people accessing it at any one time.

I get this also not only in windows also when the client is Ubuntu. RDP an NX are working completly diffferent. NX needs to fill up the bitmap cache whenever you are using a screenobject for the first time. This will increase the CPU usage on the server, because the bitmaps are cached and it will increase the bandwith consumption, because those pictures need to be delivered to the client. But the whole user feedback of input devices and the x-server ressources are working local. So it is very typical for NX to have a changing bandwith usage. Please keep in mind, that x2go is not developed to be an NX replacement. There are various Open Source clients and even servers which are completly compatible to NX. The idea of x2go was to develop a complete open Terminal Server by using as much as possible already existing native linux projects. For a typical connection time to a x2go server using WLAN you can watch our youtube video: http://www.youtube.com/watch?v=WxEsngE6qjc If you can give us more information, we'll really try to help you. It would be interesting to have an look on the ssh connection (how long does it take to establish the connection) and what services you are using (printing, file sharing, sound - > which sound system). best regards, Heinz ____________________________________________________________________ WEB.DE MillionenKlick: Kostenlos tippen, täglich 1 Million gewinnen! http://produkte.web.de/go/07/

Hi, This seems better. Ok to ask a proper question is that for login and working in the remote desktop, nxclient seems to be much quicker and responsive than x2go client in windows. Is there a reason or still need to wait for newer versions? Tks, Eric

I really don't have any experience with low power machines as servers. We are developing on a 1,5 GHZ Centrino 2GB device and we can say, that memory is more needed than cpu power. Maybe it is really a good idea to ask Paul about his servers. best regards, Heinz ___________________________________________________________ Preisknaller: WEB.DE DSL Flatrate für nur 16,99 Euro/mtl.! http://produkte.web.de/go/02/

x2go in cameroon

ich habe eine anfrage, ein schulzimmer mit 20 pc einzurichten. ich stelle mir vor, x2go-home (also ubuntu machine) einzusetzen, 2x1 servers (im fall ein austeigt, haben wir trotzdem ein netz mit allen clients) 2x10 pcengines 3x1 switches 1 für internet 2 intranet 20x1 ethernet kabeln 20X1 flach monitor 5X1 distributors warum 2 servers? nach meinen erfahrungen ist es besser 2 servers als ein, im fall der server steigt aus, so ist nicht die gesamte anlage weg. aber ich mache sonst netz mit 5 machinen, mit 10 clients habe ich keine erfharungen. dazu strebe ich low power computer, da ich sonnenenergie anpeile. als client benütze ich die alix board (www.pcengines.ch) jede anregung bin ich dankbar und es pressiert noch dazu michel in cameroon server: es gibt jetzt mini itx mit nano, aber atom 330 ist ok, ist es stark genug für 10 clients?

Hello Cougar, there was/(still is) a forum on berlios. We have decided that it would be better to store all messages regarding x2go in one place. To ease the access the mailing list is registered by gmane. Please read this post and visit : https://lists.berlios.de/pipermail/x2go-dev/2009-December/000221.html If you are using gmane , the mailinglist will just look like a forum and you'll be able to post messages. An overview of all functions can be found here: http://dir.gmane.org/gmane.linux.terminal-server.x2go.devel A very good feature -in my eyes - is the possibility to access the list by rss feed. Welcome on the list! best regards, Heinz > -----Ursprüngliche Nachricht----- > Von: "cougar" <voipster3(a)gmail.com> > Gesendet: 16.01.10 06:30:33 > An: x2go-dev(a)lists.berlios.de > Betreff: [X2go-dev] Forum > Hi all, > Just wondering is there a plan to start a forum? > > Tks Rgds, > Eric > > _______________________________________________ > X2go-dev mailing list > X2go-dev(a)lists.berlios.de > https://lists.berlios.de/mailman/listinfo/x2go-dev > --heinz-m. graesing-- ______________________________________________________ GRATIS für alle WEB.DE-Nutzer: Die maxdome Movie-FLAT!

cups-x2go fails on Ubuntu
by John A. Sullivan III 16 Jan '10

16 Jan '10

Hello, all. I don't think this is a major issue for us as we plan to use a centralized Debian cups server. However, in our initial testing, we attempted to use X2GoPrint with X2GoServer-Home on Ubuntu Hardy. X2GoServer-Home is working fine and x2goprint installed without a problem. However, the cups-x2go installation failed. It complained of a missing dependency of cups-client. I believe the problem may be that Ubuntu calls this package cupsys-client. I thought I'd point it out as I would imagine it is a trivial change to make in the packaging if we want a cups-x2go package to go along with X2GoServer-Home and X2GoServer-One - John

FUSE reFUSEs to install
by John A. Sullivan III 15 Jan '10

15 Jan '10

Hello, all. We are trying to install a Debian Lenny vserver on a CentOS 5.4 host running a custom kernel - 2.6.28.7-vs2.3.0.36.7. We are trying to install fuse-utils and sshfs for use wit X2Go (a great project for those unfamiliar with it - www.x2go.org) We keep getting: Setting up fuse-utils (2.7.4-1.1) ... creating fuse group... udev active, skipping device node creation. udev requires a mounted sysfs, not started. failed! failed! invoke-rc.d: initscript udev, action "reload" failed. dpkg: error processing fuse-utils (--configure): subprocess post-installation script returned error exit status 1 dpkg: dependency problems prevent configuration of sshfs: sshfs depends on fuse-utils (>= 2.7); however: Package fuse-utils is not configured yet. dpkg: error processing sshfs (--configure): dependency problems - leaving unconfigured Errors were encountered while processing: fuse-utils sshfs In the past, we simply created the fuse device manually and added SECURE_MOUNT SECURE_REMOUNT BINARY_MOUNT to ccapabilities Short of giving SYS_ADMIN and running udev, how do we get this to work? Thanks - John

x2go Web client is needed
by brian mullan 09 Jan '10

09 Jan '10

The effort of supporting on 3 different installable clients for Mac, Linux, Windows would seem *lessened* if there was just a single Web client (java/php) for x2go. It would also open x2go's server side capabilities to many more potential users.
