Usability with latency ~200ms
by Stefan.Klingner＠brodos.de 14 Nov '11

14 Nov '11

Hi, we are trying to use X2Go to provide a devolpment environment for our employees in India. The problem is that the connection to India is really bad (latency ~200ms) and so working with X2Go is currently not possible. Is there a way to improve the performance on the X2Go client/server configuration? Does anybody have experience with such a szenario? Please help.

Re: [X2go-User] x2go Client on Mac OS X Lion (10.7) [Workaround]
by Neil Hunt 11 Nov '11

Stephan, Thank you so much for those steps. Indeed, it worked great for me and I can now promote migration to Lion at our company as well as continue to recommend x2go. FYI, I did get that error Invalid MIT-MAGIC-COOKIE-1 key, but your suggested command worked out. Not sure how you figured this all out but I sure do appreciate it!

LAN connection slow
by Ralph Sikau 11 Nov '11

Hi, the x2go clients offer LAN as the fastest connection type. Though we have a gigabit Lan here, this connection type is much slower than DSL or WAN. How comes? Regards, Ralph

NX workaround packages, temporarily SOLVES: crashing X2Go sessions
by Mike Gabriel 09 Nov '11

09 Nov '11

Dear all, (resending this mail to x2go-user, x2go-dev, corrected mail address of announcement list, fixed minor inaccuracies of the first version sent to the lists) as many of you have reported, there are major issues with the version of NoMachine's NX libraries that are currently provided on packages.x2go.org and in X2Go's Ubuntu Launchpad. The occurring crashes of X2Go sessions do not relate to the code itself but to the way the code (from X2Go Git) currently is built (i.e. compiled and packaged). Only five weeks ago, Alex, Reinhard and Mike could narrow the problems down to the build method being used. The issues probably also apply to the way other NX related projects build their (Debian-ic) packages. So, if anyone needs more details on this, feel free to contact us on this list. As a matter of fact, we currently can't consider the available NX libraries provided on packages.x2go.org (with obvious effect on x2goagent) as ,,stable'' at all; session crashes can easily be reproduced on various setups. Certain actions within the X2Go session cause naughty reconnect or disconnect messages for the client user and many times the sessions die seemingly without reason. This problem is due to NX libraries being built against the distribution's X server development files and not against the development files of nx-X11 (Xserver provided by NoMachine). Unfortunately, the former build method, however, has been state-of-the-art for the Debian-like packages ever since. We are working on a new way of building those packages, see below. As there have been many complaints we'll respond by offering intermediate packages that do not contain these problems. However, these packages have been built in a non-Debian state-of-the-art way and the solution provided from us is only a temporary workaround until we have solved the package build method for these packages. Alex has built packages using a non-Git based build environment, one we used before we changed to working with Git. The provided packages have the same package names as found in Git, they also have a slightly higher version number so your systems will upgrade easily if you use the ,,workaround'' package set: libxcomp3 libxcompext3 libxcompshad3 These new packages should do their job well, as we can't reproduce the reported crashes with them anymore. Currently, we are working with high pressure on cleanly-built NX packages (see: Git project nx-libs.git, test branch, also x2goagent.git, test branch), so that we can provide Git based NX packages soon again. DEBIAN ====== If you want to use those packages on Debian, please make sure that you have deb http://packages.x2go.org/debain squeeze main (or wheezy main, sid main) as package source configured in your APT system. If that is the case simply upgrade the above named packages and then you should get the workaround NX packages installed. $ apt-get update $ apt-get install libxcomp3 libxcompext3 libxcompshad3 If encountering errors during installation, also make sure to uninstall all development packages around NX libs before upgrading to the workaround package set: $ apt-get remove libxcomp-dev libxcompshad-dev libxcompext-dev $ apt-get remove libxcomp3-dbg libxcompshad3-dbg libxcompext3-dbg We'll keep the NX workaround packages in the "main" area of our Debian repos as long as needed. You'll still have access to the git based packages using the "heuler" area. (deb http://packages.x2go.org/debian squeeze heuler). UBUNTU ====== For people who use Ubuntu GNU/Linux and install X2Go from Launchpad the solution is not as simple. We have provided tar.gz files containing the needed packages. Download the tar.gz file appropriate for your Ubuntu version from http://packages.x2go.org/nx-3.5-workaround/ubuntu/ Extract your downloaded tarball (=tar.gz file) and install packages manually (e.g. for Ubuntu oneiric): $ mkdir ubuntu-x2go $ cd ubuntu-x2go $ wget http://packages.x2go.org/nx-3.5-workaround/ubuntu/nx-3.5-workaround_ubuntu-… $ tar -xvzf nx-3.5-workaround_ubuntu-oneiric.tar.gz $ eval $(dpkg-architecture -s) $ dpkg -i *${DEB_HOST_ARCH}*.deb When encountering problems, also make sure to remove the development packages around NX before installation of the workaround packages: $ apt-get remove libxcomp-dev libxcompshad-dev libxcompext-dev $ apt-get remove libxcomp3-dbg libxcompshad3-dbg libxcompext3-dbg This is a temporary solution for the time we can't guarantee that the Git based built packages are stable. From our perspective stability should come first, but of course we will try hard to solve the build problem so that we can use our X2Go Git based build environment for NX libs, as well (again).

no session resume
by Ralph Sikau 05 Nov '11

05 Nov '11

Hello, I'm using the x2goserver (latest version) on a virtual xen machine running an LMDE desktop. The strange behavior is that the x2go sessions are never resumed but whenever I login, a new session is created and all programs have to be started again. The client is a Windows XP PC, and it makes no difference whether I use the windows client or the pyhoca gui to connect. Can anybody tell me what is going wrong here? Regards, Ralph

x2gothinclient: compression and sound
by Michael Hierweck 05 Nov '11

05 Nov '11

Hi all, I'm trying to (re)migrate our thin clients (Intel Atom 1.6 GHz) from plain X11/XDMCP to x2go again using the latestet Debian Packages (Squeeze). First of all I wonder about the recommended compression mode and level. With link type LAN and compression nopack I experience heavy CPU usage on the (thin) client side (20% Xorg and 30% x2goclient) while reading mails and even more latency than I experienced with plain X11 before. Furthermore sound forwarding does not work even though it is active in the session setup. pulseaudio configuration and cookie has been set: $ export |grep PULSE declare -x PULSE_CLIENTCONFIG="/home/michael/.x2go/C-michael-53-1320436144_stDGNOME_dp16/.pulse-client.conf" $ cat $PULSE_CLIENTCONFIG default-server=localhost:30002 cookie-file=.x2go/C-michael-53-1320436144_stDGNOME_dp16/.pulse-cookie x2go seems to bind to some ports, 30002, too: # netstat -tupen |grep 1004 tcp 0 8 127.0.0.1:38073 127.0.0.1:30001 ESTABLISHED 1004 3080993 18624/sshd: michael tcp 0 0 127.0.0.1:38338 127.0.0.1:30002 ESTABLISHED 1004 3083062 19032/gnome-volume- tcp 0 0 127.0.0.1:30001 127.0.0.1:38073 ESTABLISHED 1004 3080994 18815/x2goagent tcp 0 0 127.0.0.1:30002 127.0.0.1:38338 ESTABLISHED 1004 3083063 18887/sshd: michael But this is what paplay tells when invoked from a terminal inside the x2go session: $ paplay -v /usr/share/sounds/KDE_Startup_new.wav Opening a playback stream with sample specification 's16le 2ch 22050Hz' and channel map 'front-left,front-right'.

Documentation needed and error
by Sebastian Gödecke 04 Nov '11

04 Nov '11

hi there, i want to use x2go on a sles11 and opensuse 11.4 system. I've installed it from repositories but now i need a documentation how to configure x2go. Is there anything ? I get an erro if i try to connect from my client to the server: Verbindung fehlgeschlagen Schreibfehler: /home/username/.x2go/ssh/socaskpassFGIS4V But this file would be randomized created so it won't work to "touch" it. Next file could be named "socaskpassHSDF6K" Foldersettings are 700 Are there some spezial settings for running x2goclient_gtk ? what to do here ? regards sebastian

HI Sebastian, changing over to x2go-user ML... Installation issues are better off there. @Sebastian: if not subscribed to x2go-user, please do so.

First thought is: checkout why there is a write error on the given file. (disk full, permissions, is the folder /home/username/.x2go/ssh being created?)
