x2gothinclient write problem
by Markus Homburg 12 May '11

12 May '11

Hi there, I have some strange issues with x2gothinclient. For installing I used this manual: http://wiki.x2go.org/installing_x2go_thin_client_environment_debian Because of using squeeze instead of lenny I changed a couple of things: - debootstrap - repos - apt-get install x2gothinclient instead of x2gothinclientsystem But that should not be the problem. The tftp boot works like a charm, but in the NFS "bootsteps" I get come errors/warnings: [...] cannot create /tmp/lean: Read-only file system [...] cannot create /var/run/utmp: Permission denied [...] cannot create /var/run/motd: Permission denied [...] There are some more errors and the problem is, in my opinion, that it is not possible to write on /tmp, /var, etc. The NFS-Share is exported "ro" as described in the documentation. Should be there a "fake" writable /tmp, /var path or a special mountpoint? Best regards Markus

x2go with Gnome 3 ?
by John Williams 05 May '11

05 May '11

Has anyone successfully run x2goserver(-one) with Gnome 3 ? I just upgraded my Archlinux system to Gnome 3, and x2goserver-one stopped working with Gnome. It gave a message about hardware not being suitable and it is reverting to gnome fallback. Unfortunately, it seems it was a one-time message, but I cannot get the message back, otherwise I would post the exact error message. What happens is that I end up with an x2go session with a plain desktop and a couple menus of apps, and that is all. If no one has gotten x2go working with Gnome 3, can anyone suggest where I need to start looking to solve the problem? I don't really know where to start. I already tried /usr/bin/gnome-session as a custom command from the x2go client, but that made no difference, and now I am stuck on what to look at to troubleshoot the problem.

Ubuntu/Debian Try-Out Repositories for X2go packages from Git
by Mike Gabriel 03 May '11

03 May '11

Hi there, X2go Git ======== as many of you might have realized X2go development has moved to Git based development. The Git development site can be found here: http://git.x2go.org Not all X2go packages are available in this Git repository, but we will move more and more packages there whenever we (or you) think that work on it should be continued in Git. We are very happy about people contributing coding work at this point. Projects available as Git projects on git.x2go.org are nightly-built for Ubuntu GNU/Linux (as Moritz has announced a couple of days ago). Thx to Reinhard+Moritz for this...: https://launchpad.net/~x2go/+archive/ppa Ubuntu Packages for Trying-Out X2go =============== So, for Ubuntu we currently _only_ have nightly builds. These nightly builds are for testing purposes during development only. Use them at your own risk or rather do not use them without discussing the state of code on this mailing list first. Nightly-builds might not be stable every once in a while. They are built directly from the X2go Git repos -- no matter how broken the code there might be... Currently, you are lucky, to my knowledge all packages build and install well. We lately have started a discussion if there should be packages at our Launchpad ppa that reflect a rather ,,stable'' state opposed to the nightly-builds. I think we should continue this discussion... Debian Packages for Trying-Out X2go =============== For Debian I have set up a new reprepro package repository at this URL over the weekend: http://code.x2go.org/debian Preferrably, the URL will be renamed to: http://packages.x2go.org/debian ...but I need a DNS entry from Heinz for that. (PING!) On http://code.x2go.org/debian we have to component areas: ,,main'' and ,,heuler''. main: packages reflecting the Git-tag ,,build-main'' (refer to individual projects on git.x2go.org) heuler: nightly-builds (not quite yet, currently I have to start the build process manually) Notes on ,,main'': Packages in the main area we consider as relatively stable. As long as X2go is not available in Debian itself, you probably might try those. Notes on ,,heuler'': you do _NOT_ want to use nightly-builds for your systems, especially not for production systems. These nightly-builds (cf. Ubuntu nightly-builds) are for developmental testing only. The heuler repos is/will be really experimental stuff. Please keep that in mind. BUILDING PROCESS ================= All packages in the new Debian package repos (similar to Launchpad for Ubuntu) get built against clean Debian chroots. They are built with qemubuilder (a pbuilder/cowbuilder derivative). We currently support i386 and amd64 architectures for Debian only. For testing, we currently only need those architectures. If there is need for other archs like powerpc, armel, ... please let us know. We may consider to build the packages in ,,main'' area for these not so common archictectures, too, if there is a need for that (I have never tested if they work on those archs, though). As they are a couple of open issues around package building, I will send a couple of subsequent mails, touching those issues, so stay tuned... light+love, Mike -- DAS-NETZWERKTEAM mike gabriel, dorfstr. 27, 24245 barmissen fon: +49 (4302) 281418, fax: +49 (4302) 281419 GnuPG Key ID 0xB588399B mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

Yepp. > [...] About the named details around dependencies you are absolutely right. It is no problem to install Ubuntu lucid packages on Debian squeeze. They should run out-of-the-box. But still: my personal intention about having packages for Debian _and_ Ubuntu at hand is to reduce the questionmarks on the users' side. o you run Ubuntu -> use the x2go ppa o you run Debian -> install from packages.x2go.org/debian. I know that Heinz used to get flooded with personal mails that exactly have pointed to this question: I am using Ubuntu, but I can only see packages for Debian lenny, what shall I do? Or: I use Deb squeeze, but there are only lenny packages... ??? etc.pp. We currently have nightly-built packages available for all current versions of Ubuntu and Debian. These nightly-builds are for developmental testing only. http://wiki.x2go.org/nightly-built_packages_debian_ubuntu For Debian we also have ,,stable'' packages (main area on packages.x2go.org/debian) http://wiki.x2go.org/adding_the_x2go_repository_debian and we should also provide similar packages for Ubuntu, too, in a separate ppa. These are for the users. As long as X2go is not included in Debian (and therefore not in Ubuntu), our main objective around packaging should be providing stable packages to our current user community (I presume that the majority of current X2go users use Debian/Ubuntu). Once X2go is in Debian I would like to reduce package building to nightly builds only, again (speaking for the project internal Debian packaging). Again, I quite like having nightly builds for Debian and Ubuntu. Another current goal is to make X2go code as generic as possible so that people who want to package X2go for other distros may do this at more ease as currently possible (add Makefiles to all packages -> TODO Mike, create tarball releases directly from Git). http://wiki.x2go.org/tarball_releases_of_x2go Note: the packaging for .deb-based systems has two reasons: 1. continue to provide X2go to the current user community until we have X2go in Debian (and conclusively in Ubuntu) 2. developmental testing The first aspect may disappear once the Debian packaging team has started its work. The second aspect we will probably continue ,,forever'' out of our own interests.

Build-Server
by Mike Gabriel 29 Apr '11

29 Apr '11

Hi Morty, Reinhard, Arw, Morty mentioned recently (I think in a Jabber session) that there is a build-server available at Uni Erlangen. Will it be possible to install qemubuilder on that system and use it for building X2go packages? I volunteer to do that, the qemubuilder can be used for other build jobs as well... I have looked at the different systems available for package building and I liked qemubuilder best. However, qemubuilder does only build in kvm-mode on native systems (that is: not on already virtualized systems). In Intel-based kvm-VMs it can not access the VT technology of the CPU (so-called VT nesting). However, AMD Pacifica CPUs support KVM nesting (never tried it out, though). @Morty: if you run VMs on an AMD CPU that would also be great and functional for our needs. Anyone else: if you can provide such a build server, please let me know that, too. I currently use my notebook for building X2go packages (it is a really fast one, but still, it is a notebook). The server behind code.x2go.org also runs a similar qemubuilder setup, but it only falls back to slow qemu software emulation as it already as a virtual machine...

x2goserver still has old version number scheme
by Mike Gabriel 28 Apr '11

28 Apr '11

Hi devs, hi all, @all: as many of you might have realized... we have changed the upstream version numbering scheme for X2go sligthly: version numbers like 1.2.3-4 have been changed into 1.2.3.4 @devs: the only package in Git that still has not been updated to the new scheme is the x2goserver package. Are there any objections to kick a release (3.0.99.6) in Git to make this version numbering scheme conversion complete (regarding projects in Git)? A reason for putting this on the agenda is a dependency fix in the x2goserver package for Debian/Ubuntu (depends on xbase-clients). Heinz, Alex? BTW: this would also affect the x2gomimebox feature recently pushed to Git and the latest patches for x2goprint. Will those be accepted?

Launchpad PPA, derive more stable packages from nightly-builds

x2goserver depends on xauth?
by Mike Gabriel 27 Apr '11

Hi there, today I installed the x2goserver package (Debian build in main area on code.x2go.org as in Git tag build-main) on a fresh server. After installation I could not login to the X2go server. I then simply installed the xinit package and then log-in worked. However, I think that it rather might have been the xauth package that was missing on the system - and got installed as a dependency of xinit. I think we should add xauth to x2goserver as dependency (or x2goagent?)!?! Or might that issue be also related to any other of the xinit package's dependencies: quote: """ Depends: libc6 (>= 2.3), libx11-6, coreutils (>= 7.4-1), x11-common, xauth Recommends: xserver-xorg | xserver, xterm | x-session-manager | x-window-manager | x-terminal-emulator """ Greets, Mike -- DAS-NETZWERKTEAM mike gabriel, dorfstr. 27, 24245 barmissen fon: +49 (4302) 281418, fax: +49 (4302) 281419 GnuPG Key ID 0xB588399B mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

Hi Reinhard, for Python X2go on Ubuntu lucid two dependencies are not fulfilled with default lucid systems: python-gevent (>=0.13.1-1) python-setproctitle (>=1.0.1-1) If we add the python-x2go & co. packages to the X2go PPA (nightly-builds) can we also add those two as dependencies? They do not need to be build regularly, they just have to be in the same repository. Both packages are available in Maverick, so they may be backported from there.

Nightly Ubuntu packages
by Moritz Struebe 22 Apr '11

22 Apr '11

Hi there, with a bit of help of Reinhard I have set up a ppa [1] containing nightly builds for Ubuntu Lucid and Maverick. Using this ppa allows simple installation and testing of nightly builds. Please remember that these are nightlys, pulled directly from GIT [2], and therefore not necessarily stable builds. There will be a ppa containing releases and it is also might be that there will be another ppa containing "tested" builds in the future (if there someone is willing to maintain it). Currently there are no builds for Karmic Hardy and Dapper, as this might cause some extra work testing. (I personally don't see any trouble adding them, if there is someone willing to test and maintain them.) Also no Natty as nxcompext does not build (Feel free to look into it [3]).

vcxsrv + libssh all set except XP printing
by John A. Sullivan III 21 Apr '11

21 Apr '11

Hello, all. We continue to heavily test 3.0.1-18 and vcxsrv. It all seems ready to go except for one issue - it completely crashes consistently when printing under Windows XP as Phil previously reported. This problem does not exist in Windows7. As this appears to be the last issue before releasing this version and solving the show-stopping problems we have with Xming, I would think this is a high priority. However, has anyone else replicated this problem? We do not have a large test population but it has crashed immediately for both XP testers. So, again, can anyone confirm this critical bug? Thanks - John

local apps on a thin client anyhow?
by Meik Hellmund 21 Apr '11

21 Apr '11

Hi, I am just playing around with the older x2go thinclient debian packages and I wonder if it is possible to add local apps (as in LTSP). I have not yet a clear understanding of the x2go infrastructure, so please be patient. What I tried: I switched to a console on the thin client, mounted the homes via NFS, set DISPLAY=0:0 and started an X app on the client - and voila, it appears in the client's x2go session. But it is not managed by the window manager since the window manager runs on the server. So it has no border and can'tmoved around etc. Is there some better way to do this? Is it possible to somehow stack a local and a server window manager?

x2godropbox renamed to x2gomimebox
by Mike Gabriel 19 Apr '11

19 Apr '11

Hi there, on request from Heinz I have ,,dropped'' the name ,,X2goDropbox'' and thought about a new name that does not confuse with any web service currently offered on the internet. What came to my mind is ,,X2go MIME box''. Again: the MIME box is a feature in PyHoca-GUI that was originally requested by Dick Kniep. It allows to export files from the X2go server session to the client (uni-directional). One use case might be: you have a server application that generates an ODS spread sheet. The application has an export button that will copy this ODS file to the $X2GO_MIMEBOX directory. On the client a thread watches this MIME box and on incoming files and will open the default application for the file's MIME type. I have now renamed everything in the dropbox patch and committed it into Git: x2goserver: http://code.x2go.org/gitweb?p=x2goserver.git;a=commitdiff;h=d352a2b49a9e246… python-x2go: http://code.x2go.org/gitweb?p=python-x2go.git;a=commitdiff;h=6fa45031b5d85c… pyhoca-gui http://code.x2go.org/gitweb?p=pyhoca-gui.git;a=commitdiff;h=eb0b2aa4b6211b0… I hope the new name is now acceptable to everyone.

pending/x2godropbox patch
by Mike Gabriel 19 Apr '11

19 Apr '11

Another hi-devs, I would also like to see my dropbox patch (needed for the X2goDropbox in Pyhoca-GUI) in the x2gomountdirs script of x2goserver/master. If I do not here a veto within the next four days, I will push the patch to code.x2go.org... http://code.x2go.org/gitweb?p=x2goserver.git;a=commitdiff;h=050bc008107fe2b… The X2goDropbox provides an export spool mechanism (similar to the cups-x2go/x2goprint duo) for any MIME type you allow (client-side-wise) to be dropped into that X2goDropbox. On the server-side you simply have to copy a file into $X2GO_DROPBOX which points to ~/.x2go/C-<session_id>/dropbox The file will arrive on the client side (SSHFS) and the default application for this file will be opened (locally on the client).

The nightly-builds (heuler) will always use the HEAD in Git. The should-be-rather-stable-builds shall be packages that have already been built by Launchpad and represent a state that is also marked in Git (either by tag or branch-off). So a Launchpad automation I think of could be: 1a. we tag a project in Git with a special tag, e.g. build-main 1b. alternatively, when we tag a release version, we branch-off from master in a branch called build-main 2.

Tagging in X2go Git
by Mike Gabriel 19 Apr '11

19 Apr '11

Hi esp. Reinhard, I have just discussed with Morty a good strategy to always have a ,,latest'' tag in X2go Git projects that refers to the newest tag. The idea is to provide nightly-builds as well as ,,stable'' builds (which refers to the latest tag in Git). Would it be sensible to add some script part to one of our update scripts on the Git server that maintains a ,,latest'' tag: if a new tag is pushed remove tag ,,latest'' and set ,,latest'' tag after push again? How could this or some smimilar mechanism be achieved?

What is happening is that the Perl script, x2goprint, moves the PDF from /var/spool/x2goprint into the users mounted spool directory and then creates the .ready file. The x2goclient looks for any new files in that directory and if it sees the .ready file it pops up the x2go print dialogue window. Now, looking at the code it appears to remove the file as-well; in 3.01-18 the pertinent code is in onmainwindow_part4.cpp line 200. I am thinking this is a timing issue with respect to the .ready file being written and the slot which monitors the local spool directory firing off an event. Just not sure how to solve it yet :( -- Thanks, Phil

X11 connection rejected because of wrong authentication

But X gives: "X11 connection rejected because of wrong authentication" X apps open with manual ssh connection. On one update of xorg, X2go started working but only for the first session. I tried removing the .Xauthority file and it gets recreated, but still the same.

x2gothinclinet / tmpfs
by Moritz Struebe 11 Apr '11

Hi there as there has been some talk about tmpfs on the list, I decided to start the tmpfs branch on the official server. You can find it here: http://code.x2go.org/gitweb?p=x2gothinclient.git;a=shortlog;h=refs/heads/tm… The interesting folder is the x2gothinclientmanagement. There is a short README explaining what the different scripts do. Please remember, that this is work in progress and not very well tested. None the less it should speedup your thin-client creation.

I already had a look at the printing code in x2go some time ago. There basically are three components: o cups-x2go o x2goprint o x2goclient If I recall it corrently the interaction between cups-x2go and x2goprint was not optimal then. I guess it was cups-x2go that left over some print job files whenever a print job was sent to the client, but I am not sure anymore. A person that was not in the x2goprint group also created orphaned print jobs in /, because they were not picked up properly by x2goprint. My observations all were a little odd. Whenever I have time, I will take a look at the mechanism and come up with some patches. The x2goprint <-> x2goclient communication is rather simple: x2goprint drops two job files in the spool dir: <job>.pdf and <job>.pdf.ready. The X2go client has to run a thread that watches this spool dir (it's in the x2go session cache folder under ~/.x2go/C-.../spooll). On each incoming print job it has to wake up and take over the task of processing the print job. My Python implementation of this printqueue can be found here (if you prefer Python to Perl for a lecture...): http://code.x2go.org/gitweb?p=python-x2go.git;a=blob;f=x2go/printqueue.py;h… Greets, Mike -- DAS-NETZWERKTEAM mike gabriel, dorfstr. 27, 24245 barmissen fon: +49 (4302) 281418, fax: +49 (4302) 281419 GnuPG Key ID 0xB588399B mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

Please note that I have also patched x2goprint that's stil pending for inclusion in x2goserver (we will drop the separate x2goprint project): http://code.x2go.org/gitweb?p=x2goserver.git;a=shortlog;h=refs/heads/pendin… The patch makes x2goprint usable on NFS mounted home directories. Furthermore, I guess it needs patches of cups-x2go as well. Because there are indeed some lost jobs and also zombie files that collect up (e.g. in /). I guess the best approach for providing patches and share your work would be to work on the code base in Git on code.x2go.org.

VcXsrv clipboard issue
by Dick Kniep 08 Apr '11

08 Apr '11

Hi list, Mike has developed a very nice python gui client. We are going to use this with our product. However it seems that with the latest version of VcXsrv (1.10.0) there is an issue with the clipboard. Copying from my PC to the X-session works OK. However, the other way around does not. There is a new parameter --clipboardprimary that should alter the behaviour of the clipboard. However it does not seem to make any difference. Anyone else seen this behaviour and hopefully knows something to solve this? Dick Kniep Lindix BV tel. 036-5215580 mob. 06-50991858

x2gothinclient w/o LDAP
by Mike Gabriel 08 Apr '11

08 Apr '11

Hi Morty, I have a customer that has patched the x2gothinclient to use local session profile files. On the way he discovered that X2go thin client systems do not have the loop network device set up. Could you give your opinion on that? File: "/etc/init.d/ramdrive" after: cat /proc/mounts> /ramdrive/mtab # setup lo interface ifconfig lo 127.0.0.1 netmask 255.0.0.0 He also has modified the thinclient script in a way that you can run x2goclient on the thin client without LDAP. He provides a session profile ,,sessions file'' and puts that into ~/.x2goclient/sessions. But he also need some fixes for that. Maybe we see an option to incorporate this in the x2gothinclient, so that both methods are available in the code and it merely needs some commenting and uncommenting or whatsoever to enable/disable LDAP/sessions-file.

Help us with the X2go-Wiki
by Mike Gabriel 07 Apr '11

07 Apr '11

Hi all, many of you have implemented many features and use cases of X2go. This set of brilliant ideas is still not in public and it will be scattered over the internet (in newsgroups archives etc.) or even lost if we do not take our time to bundle this valuable knowledge. So I may ask from you all: Please help us fill or Wiki. May I ask people to become active and help documenting X2go? We are esp. interested in your modifications and adaptations of X2go? Please send a request mail to either of these lists (x2go-user, x2go-dev) to get a Wiki account and your request will be processed ASAP. The developers (Heinz, Alex, Morty, Reinhard, Arw, Mike, ...) are also going to use the wiki more intensively in the future. For the current roadmap you can visit this page: http://wiki.x2go.org/roadmap Looking forward for more collaboration!!!

libjpeg-turbo
by brian mullan 07 Apr '11

07 Apr '11

Mike I've been using libjpeg-turbo for months now on both ubuntu 10.04 and 10.10 (x2go clients & servers). I put it on both client machine & on server assuming it would benefit jpeg cpu utilization and although I don't have the info handy now I thought I'd sent out a couple screen shots of cpu utilization with and with-out libjpeg-turbo installed. Sorry I can't remember the number off-hand but there was a pretty significant difference On the client machine that may or may not mean much but on a server hosting a lot of desktop users I figure its a good cheap performance (or capacity) bump depending on how you looked at it. I "think" the new debian and the upcoming ubuntu may it in their repositories now. I'm assuming other distro's too? http://libjpeg-turbo.virtualgl.org/ Brian
