X2Goplugin
by Vasilica Petcu 21 Feb '12

21 Feb '12

Greetings, I use to play with x2go plugin some time ago, when it was available as a xpi firefox extension. I have visited your wiki page about the plugin, but as you know, it is not updated. Could you give me some hints how can I make a page where the user access it and download automatically the plugin, install it on the client machine ? This option is still available, right ? Thank you

Preferred settings for X2go LAN use
by newsgroups.mail2＠stefanbaur.de 21 Feb '12

21 Feb '12

Hi everyone, any recommendations on what settings I should use in X2go-Client when the server is on the same LAN as the clients, and I want to watch youtube (with Pulseaudio sound) via X2Go? The default settings already look (and sound) promising, but it seems there are a few glitches... and I'm wondering if they are real bugs or just side effects of a less-than-ideal session setting. I'm currently using a 100MBit switched LAN, with the option to upgrade to 1 GBit LAN if that would make a major difference. -Stefan

Traffic shaping nightmare - missing SSH TOS bits
by John A. Sullivan III 21 Feb '12

21 Feb '12

Hello, all. I've been working on a project to implement traffic shaping to conform to 95th percentile billing including our X2Go virtual desktops. One of the challenges is prioritizing the interactive X2Go traffic (screen, keyboard, mouse) differently from bulk traffic like local share transfers, printing, and possibly sound. I thought this would be trivial because of the SSH transport since SSH sets the minimize-delay bit for interactive traffic and the maximize-throughput bit for bulk transfers. Thus we could distinguish the packets by looking at the TOS bits. This is how the default Linux pfifo_fast qdisc does it anyway. I took a packet trace just to confirm it and, to my horror, I see that we are not setting any of the TOS bits and thus not prioritizing interactive traffic even with the default traffic shaping. I'm guessing this is a casualty of moving to libssh. Is there any way to set the TOS bits for interactive to 0x10, bulk to 0x08 as it is in OpenSSH?. It would be really nice if sound could be configured either way according the the administrator's preference. Unfortunately, I did not see anything in the libssh documentation to show how to do this although I do not claim to understand it. This is a critical issue for any WAN based deployments like ours. Thanks - John

Font colour in x2goclient in case of dark system theme
by Milan Knížek 20 Feb '12

20 Feb '12

Hello, the x2goclient has hardcoded light appearance for the various widgets (main window, session list, login window, progress of logging in), which does not work well with dark system theme: the white font is not distinquishable from the background. I have checked the Qt documentation and there seems to be more ways on how to accomplish that. So far, I have used three various methods: labelname->setStyleSheet("QLabel { color : black; }"); or cpal.setColor ( QPalette::Text, Qt::black); or QString fonttemplate=("<font color='black'>%1</font>"); nameLabel->setTextFormat ( Qt::RichText ); nameLabel->setText ( fonttemplate.arg( text ) ); which kind of works, though it requires to be written repeatedly throughout the code (sessionbutton.cpp, onmainwindow.cpp, onmainwindow_part4.cpp) for individual widgets and so far I am not able to use a single approach for all widget types (QLabel, QMenu, QPushButton, etc.). The first method seems to be the most general and simplest, however. Is there a way to set application-wide font colour for anything that appears in the widgets, but not in app menu and other windows (Settings, Session Settings, etc.), because these are styled with the system-wide dark theme? Where in the code? P.S. Sorry for possibly stupid question, but since I am not a coder, it is rather a trial & error approach and a lot of googling...

I18n - how to do it
by Moritz Struebe 20 Feb '12

20 Feb '12

X-Posting to i18n and dev (Please make sure we continue this) Hi there, as i18n is getting more dynamic at the moment, I remembered our discussion from September last year. One of the things we looked at was www.transifex.net. I think we should reconsider looking at this, as it will allow to translate x2go without the need of using git, but using a web interface. And they have an API, as well as a simple client, so we can script the up- and download of translation files. As it is just used as a tool for translation, we take no risks. In the worst case, we can just switch to a different service or go back to the current workflow. Any comments? Cheers Morty -- Dipl.-Ing.

translating X2Go
by Mike Gabriel 20 Feb '12

20 Feb '12

Hi all, over the weekend Daniel Lindgren and Terje Andersen have added Swedish and Norwegian translations to X2Go Client and Pyhoca-GUI. We have set up a wiki page together that explains how translating X2Go works: http://wiki.x2go.org/wiki:development:i18n The translators communicate on: x2go-i18n(a)lists.berlios.de We currently need help with any language apart from: German Bokmal (Norway) Swedish The following language we have translators for, but the teams could grow here: Dutch Russian Spanish (currently only for PyHoca-GUI) Apart from the named language no other languages are supported within X2Go components. If you are shy with coding but speak a language that is not on the list here (or that is on the bottom list), then do not hesitate to support the i18n team of X2Go. Join the list... http://lists.berlios.de/mailman/listinfo/x2go-i18n ... and start translating X2Go into your regional language!!! Welcome everyone!

New major distribution builds available for X2go
by Michael Kromer 20 Feb '12

20 Feb '12

Hi all, as announced previously I have good news: We have a very large set of packages for the following distributions: - openSUSE 12.1 & Factory (12.2) - Fedora 15 - Fedora 16 And now we can say x2go is enterprise-ready: - SLES 11 - RHEL 5 - RHEL 6 At this point I would like to thank Jan Engelhardt - Without him this wouldn't had been possible in such a short period of time. To see the full OBS project please take a look at: https://build.opensuse.org/project/monitor?project=home%3Ajengelh%3Abranche… To add the repositories, please navigate to: http://download.opensuse.org/repositories/home:/jengelh:/branches:/X11:/Rem… The SUSE based packages have been tested and are working great. All distributions have been built to only depend on what is included within the base distro packages. We are _not_ amused by the behaviour like Red Hat works with extended packages they don't want to give support for (like by calling EPEL "a well-maintained" repository [1]). We also must say, that the "modern" versions have been a lot "easier" than the rest, just because of the dependency stuff. All packages have been verified through all kind of (and sometimes also super weird stict) brpchecks and rpmlint checks, so the package format should be fine with about any distro which takes care of clean buildroot-based package building. There has been a lot of effort to generalize the packages to have just one single SPEC-file for on package on all distros. This resulted in various patches we kindly request to get upstream, as we really think these patches are a great enhancement. As a result of what we had as a code base and the build requirements we were not able to provide x2goplasmabindings for the older (enterprise) distributions, for example. Now about what's coming next: - Please test, test, test. Just send us any feedback back to this list, as we really want x2go to work on more than debian/ubuntu. - For the moment we concentrated on the SQLite based stuff, although PostgreSQL should also work - We hope to see some tarballs regarding the plugins which have been created some time ago (http://plugin.x2go.org is offline :() to get them packaged as well. - Looking to get all our patches upstream with X2Go main development (Alex, Heinz-Markus) - Get all packages to the (broke) upstream OBS project X11:RemoteDesktop:x2go Feel free to comment, suggest, whatever - Thanks!

[PATCH] xauth file location mismatch in x2gostartagent
by Milan Knížek 20 Feb '12

20 Feb '12

Hello, the /usr/bin/x2gostartagent script does not sufficiently specify the location of $XAUTHORITY file for the xauth command, while the command line for starting x2goagent refers to a specific location $HOME/.Xauthority. Usually, this works, because if nothing is specified on the command line for xauth and the $XAUTHORITY variable is not defined, it falls back to $HOME/.Xauthority. Nonetheless, recent GDM versions set XAUTHORITY to /var/run/gdm/auth-for-$USER-blabla/database. As a result, when opening a shadow session as another user, /usr/bin/x2gostartagent adds the cookie to $XAUTHORITY (/var/run/gdm...) and then starts x2goagent -auth $HOME/.Xauthority, which fails obviously. The attached patch removes the -f $HOME/.Xauthority parameter from the x2goagent command line to resolve the problem. It also removes a redundant '-S' parameter (there is already $SESSION_TYPE there). Can users of other distributions or display managers test if it does not break something else? (It works on Arch Linux with GDM and Xfce.) Regards, Milan -- http://www.milan-knizek.net/ About linux and photography (Czech only) O linuxu a fotografování
