It may well be, that the issue is solved in python-x2go 0.5.0.3. But not sure. Please report back what exact exception is thrown. Can I test pyhoca-gui on the WinBuilder machine?

Testers Wanted: PyHoca-GUI for Windows 0.5.0.3-20150124
by Michael DePaulo 24 Jan '15

24 Jan '15

Hello X2Go users, It's been a long time since a stable version of PyHoca-GUI for Windows was released. (.0.4.0.8 was released on 2013-08-27) I have started maintaining PyHoca-GUI for Windows. I managed to build 0.5.0.3 successfully. I am making a build available today, so its version string is 0.5.0.3-20150124 http://code.x2go.org/releases/binary-win32/pyhoca-gui/releases/0.5.0.3-2015… Please test and provide feedback (via either replies or by reporting bugs). Since it is has been so long, I am concerned that there might be Windows-specific regressions. If no new "grave" or "critical" bugs are reported within a few days, I will announce this as a release on x2go-announcements & I will update the link on the X2Go home page. If anyone would like to contribute or inspect the source, this build was built from the 0.5.0.3-mswin branch. http://code.x2go.org/gitweb?p=pyhoca-gui.git;a=shortlog;h=refs/heads/0.5.0.… -Mike#2

connection failed DBI
by Brent S. Elmer Ph.D. 23 Jan '15

23 Jan '15

I have a new x2go server setup on a Red Hat 6.3 system. When I try to connect to it I get the following: Connection failed DBI connect('dbname=/home/x2gouser/x2go_sessions','',...) failed: unable to open database file at /usr/lib64/x2go/x2gosqlitewrapper.pl line 89 [limit users] at /usr/lib64/x2go/x2gosqlitewrapper.pl line 89. On the server, I tried to do a x2godbadmin --createdb and I got: Can not find user (x2gouser) So, I added user x2gouser and redid the x2godbadmin. Now I get the error above. I normally run Debian machines and have never had to do the adduser or x2godbadmin that I can remember. What do I need to do to get the x2go server working? Brent

X2Go on submarine control system

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, this is a forwarded message from Peter Brodsky, partially abridged and adapted so it makes sense to publish on the list. (He has stated that he's okay with it being made public, in message http://lists.x2go.org/pipermail/x2go-user/2015-January/002798.html) Expect my reply in a few minutes. - -Stefan - -------- Weitergeleitete Nachricht -------- Betreff: X2Go on submarine control system Datum: Fri, 09 Jan 2015 15:27:02 -0800 Von: Peter Brodsky <brodsky(a)apl.washington.edu> An: Stefan Baur <X2Go-ML-1(a)baur-itcs.de> [...] Looking ahead: The operational setup is the control system running on the Mint machine with a Windows box displaying sonar and video data. I want to put the display for the former on the latter; thus X2Go. I've got a GB switch between the 2 machines. Now: My user account on the Linux side has no password (before you have a heart attack about security, remember this is a completely isolated network). I boot up and the desktop for that account simply appears. And brings up the control display panel with it. The sub pilot doesn't want to mess around with logging in, etc. Given that - is there a particular order to which I should fire up the X2Go client vs. booting up the linux server? AND - if I also have a monitor (& keyboard & mouse) on the linux server - - what happens? (Thinking about, say, Windows Remote Desktop - I think I recall the console display just going away when a remote user brought it up - but I can't remember). OK; any suggestions helpful. Regards, - - Pete PS: Years ago I used a commercial product called Exceed, from a Canadian company called Hummingbird. Is X2GO something like that? -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (MingW32) iQEcBAEBAgAGBQJUs/9GAAoJEG7d9BjNvlEZrjsH/iM140eYpWBuE2+H8DtwIe4s fabFx+tNPEUFwnsMg0xCCkMMKML9mPhM+AxnMxm5pzt5bxJx5EP56BNAsa1ItUTd UcqnjqUOY4t7b4+2J/VU1j8A2GcvryQZ5+zLFVr40xdGnvYonpiuyfY2AtJDVu0g JvZ9d4XwQXHBp5Cx3k+kMb6QCKkrOU0R8vc4kPBcOMWVIoorSj1wRKeIgrIpsA/B xC/m9UL+im/aRv+/xI75tgR6emevS+5b2F1IJ6Fv9sftoXQ+Mkfbmh3cqUvhmJU/ n8jf81SpHzEt1Pf1JAyNQ5YPHIDwH9TvEqyi1++1oU0qGTm1KGCihDXIjlBwGtI= =qoO8 -----END PGP SIGNATURE-----

Failed to restore all required visuals, can't resume NX session on this display
by Nigra Truo 22 Jan '15

Hi, I heard that this bug should be fixed, but I still have it: When resuming a session on a Linux machine that was created on Windows. X2go server version: 4.0.1.18-0x2go1+git20141006.949+wheezy.main.1 X2go windows client version: 4.0.3.1-20141214 <http://code.x2go.org/releases/binary-win32/x2goclient/releases/4.0.3.1-2014…> X2go Linux client version: V. 4.0.3.1 Is there an error log that could give some information what is going wrong here? Thanks, Markus

Segfault of QDialog in a PyQt application
by PAILLAT Olivier SOPRA GROUP 22 Jan '15

22 Jan '15

Package: x2go Version: 4.0.3.0 Qt 4.8.6 When we run our PyQt application on our Debian Wheezy computer with an ssh -X connection it work fine But when we use X2Go to access the computer and we run our application we've got a segmentation fault at the first QDialog opening. (when we run QDialog.exec_). We recently update the X2Go version and before that update it was working fine. We found at least one post that describe the same problem in January 2014 on your bug report site : X2Go Bug report logs - #410 Segfault of _X11TransWritev in libNX_X11.so.6 with libQtGui Like suggested in this report if we run a simple application to test an opening of a dialog box it work fine with X2Go >From your experience of this bugs is there any way to solve this problem ?

Desktop sharing like "screen -x" with X2GO?
by Gabriele Santilli 22 Jan '15

22 Jan '15

Hello, I tried asking this question on IRC but I must have chosen a time when everyone was busy or away. I'm not subscribed to the list so I appreciate a CC to my address for replies. Is it possible with X2GO to connect to the same session from two different machines at the same time? Like you would do using "screen -x" for a terminal. - The two machines log in via SSH to the X2GO server using the same user - If a session is started from the first machine, it seems to me (hopefully I'm wrong!) that from the second machine I can only suspend that session (kicking out the first machine) and then resume it. I would like both machines to be connected at the same time This is actually for two different users collaborating on the same screen, but they access the same user on the server so I don't think it matters; in any case I don't want user B to disconnect user A when they connect, and they need to be on the same session because they are working together on the same application. Any help is greatly appreciated, thanks in advance.

x2go login error
by Rance Hall 20 Jan '15

20 Jan '15

My x2go server is my desktop at work and there is a .bashrc that launches keychain and loads my ~/.ssh/id_dsa into the session environment. the terminal gets the following output before the prompt: * keychain 2.7.1 ~ http://www.funtoo.org * Found existing ssh-agent: 1829 * Known ssh key: /home/rhall/.ssh/id_dsa Then you get a bash prompt. This output becomes the text of the error message when I try to connect to this same box via x2go-client. The relevant lines in .bashrc are: /usr/bin/keychain ~/.ssh/id_dsa source ~/.keychain/rhall-sh

Stuck in Fullscreen
by Nigra Truo 17 Jan '15

17 Jan '15

Hi, I use X2go from a Windows 7 machine and have noticed that now one session with one user always goes into full screen mode, although I don't want this. Is there a way to set this anywhere in the client config? CTRL ALT F does not work and has no discernable function in this session. Thanks, Markus
