Where is the openSUSE Tumbleweed repository?
by Tristan Miller 18 Sep '18

18 Sep '18

Greetings. I want to use the X2Go Repository (not the official openSUSE one) to install X2Go on openSUSE Tumbleweed. According to <https://wiki.x2go.org/doku.php/wiki:repositories:suse#adding_the_x2go_repos…> the main and extras repositories should be located at <http://packages.x2go.org/opensuse/tumbleweed/main> and <http://packages.x2go.org/opensuse/tumbleweed/extras>, respectively. The extras repository is there but the main repository is not. Has something happened to it?

Problem restoring connection on Ubuntu 18.04
by EI 13 Sep '18

13 Sep '18

I have a very strange problem with x2goserver running on Ubuntu 18.04. I get an error message on the client side when I try to suspend the connection. I also, can't reconnect to existing connections. I haven't had this problem with 16.04. I tried debugging the problem and I discovered that /var/lib/x2go/x2go_sessions database is not getting updated when connection is created. I tried erasing and re-creating the database, same problem. Even running perl script manually: /usr/lib/x2go/libx2go-server-db-sqlite3-wrapper.pl insertsession,50,blah,blah-50-1536602027_stRkonsole_dp doesn't change the database. I installed x2goserver from ppa:x2go/stable following instructions on x2go page. What could be the reason for this? How do I debug it further? Thank you. Here's version info: ~$ x2goversion x2goserver: 4.1.0.2 x2goserver-common: 4.1.0.2 x2goserver-extensions: 4.1.0.2 x2goserver-fmbindings: 4.1.0.2 x2goserver-printing: 4.1.0.2 x2goserver-x2goagent: 3.5.99.16 x2goserver-xsession: 4.1.0.2

Attention all users of Pale Moon and X2Go
by Stefan Baur 06 Sep '18

06 Sep '18

Hi List, Pale Moon (a Firefox fork) up to version 27 was/is the recommended browser to use via X2Go, as it performs way better than current Firefox and its derivatives, especially over slow links. With version 28, this is no longer true. Something broke during that update, and performance is now about as slow as with a regular, current Firefox. We have at least one commercial offer by a developer to get this investigated and fixed, and currently one customer interested in sponsoring this work. However, they fear that the actual fix might exceed their budget. So, is anyone else out there that needs a fast, and supported/up-to-date browser in an X2Go session? If so, please either reply in this thread or contact me via E-Mail.

What happened to the X2Go Blog?

Dear all, There used to be an X2Go Blog at <http://blog.x2go.org>, which could be read as an RSS feed at <http://blog.x2go.org/index.php/feed/>. They seem to have disappeared a few months ago.

Heads-Up: X2Go: The Gathering 2018 (2018-11-09 - 2018-11-11) will very likely take place at Stuttgart's hackerspace "shackspace"
by Stefan Baur 30 Aug '18

30 Aug '18

Dear $ALL, since nobody has replied to the call for volunteers for the IT-Kongress event (see <https://www.mail-archive.com/x2go-project@lists.x2go.org/msg00278.html>), and since we've lost a sponsor, compared to the previous years, it is very likely that X2Go: The Gathering 2018 will have to take place at Stuttgart's hackerspace "shackspace" (<https://shackspace.de/>) - "will have to" meaning that we're out of suitable alternatives due to both time/volunteer staff as well as financial constraints. Thus, there will be no voting period regarding the location this year, we'll simply have to pick the only option that seems to be left at the moment. The last-resort fallback option would be Ulm's youth hostel (both as an event location as well as for sleeping arrangements), but this would mean groups of 4 people would have to share one room, as they do not offer smaller rooms - which, judging from previous years' feedback, is not a situation most of our participants would be happy with. This is why we're not offering a poll with Stuttgart and Ulm as options. For Stuttgart, we're looking at a hostel-like place that offers single and double rooms, as well as at a hotel nearby, for people that prefer a higher-quality sleeping arrangement. Details will be published on the Wiki at <https://wiki.x2go.org/doku.php/events:x2go-gathering-2018> as soon as the two sites have confirmed room availability and replied with their booking cancellation terms.

keyboard layout driving me insane
by Neal Becker 27 Aug '18

27 Aug '18

On client side, I have layout set to map caps lock to ctrl. I need this also when using x2go! But it seems hard to achieve. In x2go, I try both 'autodetect keyboard' and 'don't configure keyboard'. I try mate, xfce, lxde. On the server side I would like to try also configure keyboard layout, but I don't find any good way to do it on those window managers. Unfortunately, neither KDE nor GNOME will work (both client and server are fedora 28). Sometimes I seem to hit a combination that works, but then when if the connection is terminated and I try again, it's once again not preserving my key remapping. This is driving me nuts! Any recommendations?

x2go client users don't show up in "users" or "who" (Ubuntu 18.04)
by Alan Broder 26 Aug '18

26 Aug '18

When users connect to our server via ssh or mosh, the "users" or "who" command work properly, and you can see the list of logged-in users. However, when users connect via the x2go client (from Windows or Mac) - they do not appear in either "users" or "who". Has anyone observed this problem and know how to fix it? Alan

Log-in problem after NVIDIA card update
by Alec Bayo 20 Aug '18

20 Aug '18

Hi all, Asking for help please troubleshooting an issue with x2go. Inbound connections stopped working after I updated the kernel and nvidia drivers on my centos workstation (the x2go server). On the client, the error message says "Connection failed. Failed to start X2Go Agent session with ID account-_____. X2Go Agent terminated unexpectedly. Aborting session startup." [If I attempt a connecion again the client shows a previous apparently pre-existing connection, but I cannot resume it.] On the server, the session log says "Error: Aborting session with 'Unable to open display 'nx/nx,options=...". I have attempted uninstalling and reinstalling x2goserver from epel. This symptoms are similar to an issue Mihai Moldovan resolved for Qianqian Fang in April: https://www.mail-archive.com/x2go-user@lists.x2go.org/msg02809.html However, I do not have the offending line set in LD_LIBRARY_PATH which solved the issue for Qianqian. #Contents of LD_LIBRARY_PATH (this is from env after ssh-in). LD_LIBRARY_PATH=/usr/local/cuda/lib64:/home/[...]/caffe/distribute/lib/::/usr/lib:/usr/lib/python2.7 I also attempted commenting out this setting from .bashrc, and that did not fix it. I've copied below answers to some questions Mihai asked Qianqian. The only strange thing I noticed is that Mihai asked for the contents of /usr/lib64/nx/X11 , and this is empty. The library Qianqian listed in there is located at /usr/lib64 on my server. Some more details below, answering questions that were made on this earlier, similar troubleshooting request.

Problem with SHIFT, Linux server, Mac client

Clipboard copy paste keeps being unreliable for years now
by Nigra Truo 10 Aug '18

10 Aug '18

Hi, I have been using X2go with a Debian Server and Linux Debian and Windows 7 clients for ages now. Most of the time it works flawlessly, but one thing that bugs the hell out of me is that copy paste via clipboard from Client to server does not work reliably. It works most of the time, but then it just fails, when I copy something, and paste in the target machine, nothing gets pasted. Now I want to troubleshoot and fix this once and for all. What causes this problem, why does copy paste fail sometimes? Thanks, Markus -- *Por sperto kaj lerno ne sufiĉas eterno.*

client name
by richard lucassen 03 Aug '18

03 Aug '18

Hello list, I use "Custom desktop" as windowmanager, I start the session with a script with the client name as parameter. In this way I'm able to find the client name of the station which /initialized/ the session. But is there a way to see which client /resumes/ an already existing session?

Debugging Server Side Issues
by Robert Dinse 01 Aug '18

I've installed x2goserver on Enso, a Ubuntu derived Linux. It works find as root, but as a non-root user it fails. In syslog on the server I see the following: Jul 28 18:44:08 enso /usr/bin/x2gostartagent: no free display number available, cannot start new session. Retrying (run 1).

execute xmodmap on resume
by richard lucassen 31 Jul '18

31 Jul '18

Hello list, Not an x2go problem, but maybe someone might be able to guess what is happening here. I made a chmod 755 shell script: $ cat /usr/lib/x2go/extensions/post-resume.d/010-xmodmap #!/bin/dash test -f ~/.Xmodmap || exit 0 /usr/bin/xmodmap -display $DISPLAY ~/.Xmodmap When resuming an x2go session, the script is executed, but x2go session starts but does not show up. The problem is that in one or another way, the xmodmap executable is waiting for something, but I have no idea what. Putting the xmodmap line to the background using an "&" makes the x2go session start, but the xmodmap mappings are not set. I still have to set the key mappings manually by invoking "xmodmap ~/.Xmodmap". Anyone a hint on what's going on here? R. -- richard lucassen http://contact.xaq.nl/

If you are a novice X2Go user, and you can read German, this might be of interest for you.
by Stefan Baur 20 Jul '18

20 Jul '18

Hi List, X2Go has been covered by one of Germany's most well-known and well-renowned computer magazines, namely c't. The issue will hit the newsstands today, Saturday, July 21, 2018. It's the 16/2018 issue and the article starts on page 154. This article is meant for beginners; it covers the basics of setting up X2GoServer (on Ubuntu 18.04 LTS) and X2GoClient (on Ubuntu 18.04 LTS as well as on Windows 10), and shows you how to use X2GoClient's single application, published application, and desktop environment modes, as well as its built-in file sharing feature. It also teaches you how to kill, or suspend and resume, a session, and how to get better browser performance than with regular Firefox or Chrome. If you prefer to buy and/or read it online, there are several ways of doing so: You can click on <http://ct.de/y9y2>, where you can access the link list and comment section for free - so it's worth clicking even if you don't intend to buy the article/the magazine. If you scroll up on that page, you will find a button to buy the single article using a credit card, and another button for paypal payments. Scroll up even further, and you can read the teaser text for the article. Or, you can visit <https://shop.heise.de/ct_1coa1807> and sign up for a free three-issue digital subscription (Warning: It will turn into a paid subscription if you don't cancel it in time) of the full c't magazine, Last, you can buy the full c't magazine, limited to the current edition, no unwanted subscription, online, either in PDF form by clicking here <https://shop.heise.de/katalog/c-t-16-2018-pdf?wt_pdsrc=category_c_t_magazin…>, or in paper, delivered to your postal address, by clicking here <https://shop.heise.de/zeitschriften/ct/magazin>. Assuming sufficient reader interest, there may be follow-up articles covering: * the various connection options and connection types, * using SSH key files, SSH Agents, and 2FA with one-time passwords like Google Authenticator or OATH TOTP, * using SSH proxies (Jump Hosts) as well as HTTP proxies, * the use of custom published application menus, * Session Shadowing, * Xinerama, * the various clipboard and keyboard settings, * Desktop Icons, * Client-Side Printing, * X2Go-TCE, and, last but not least, * the Session Broker. So if you're interested in learning more about any of these topics, in German, please either register a free account and leave a comment in the comment section on <http://ct.de/y9y2>, or send an E-Mail to the editor we've been assigned, Merlin Schumacher, <mls(a)ct.de>, and let him know which X2Go topics you would like to see covered in one of the next editions.

disappearing X window
by Andrew Munn 19 Jul '18

19 Jul '18

When reconnecting to a session the window appears briefly then disappears. The ssh session is still up. The only way I can get back into the session is if I go in the client and change it to fullscreen and then reconnect.
