libclutter problems (evolution, gnome-nibbles, cheese, ...)
by oongi＠web.de 03 Jun '15

Hi! I can't start evolution, gnome-nibbles, cheese in a x2go session: ---(schnipp)--- $ evolution Unable to find suitable fbconfig for the GLX context: Failed to find any compatible fbconfigs $ $ gnome-nibbles (gnome-nibbles:32235): Clutter-CRITICAL **: Unable to initialize Clutter: Unable to find suitable fbconfig for the GLX context: Failed to find any compatible fbconfigs Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged. $ $ cheese (cheese:31089): Clutter-CRITICAL **: Unable to initialize Clutter: Unable to find suitable fbconfig for the GLX context: Failed to find any compatible fbconfigs ** (cheese:31089): ERROR **: cheese-application.vala:86: Unable to initialize libcheese-gtk Trace/Breakpoint ausgelöst $ ---(schnapp)--- Possible there is the same problem with other programs, but these are the ones I found. I use the following setup: x2goserver: 4.0.1.19-0x2go2+git20150326.1064+jessie.main.1 on debian jessie x2goclient: 4.0.4.0-0x2go1+git20150526.1057+jessie.main.1 also on a jessie-system Is there a solution or workaround for this? Thanks!

Help with X2go Session Broker auth
by Michael Gale 26 May '15

26 May '15

Hello, I have been reviewing the docs here: http://wiki.x2go.org/doku.php/doc:installation:x2gobroker and am interested in: "Furthermore, X2Go Session Broker can be extended by other (non-PAM) authentication methods. The currently available authentication mechanisms in X2Go Session Broker are listed here <http://code.x2go.org/gitweb?p=x2gobroker.git;a=tree;f=x2gobroker/authmechs> ." However I am unable to find out how to enable one of the following examples: http://code.x2go.org/gitweb?p=x2gobroker.git;a=tree;f=x2gobroker/authmechs I have a custom web app I need to authenticate users against and would like to use: https_get_authmech.py <http://code.x2go.org/gitweb?p=x2gobroker.git;a=blob;f=x2gobroker/authmechs/…> Thanks Michael

x2goserver on Ubuntu Mate 15.04 with 4k monitor and high font-rendering DPI
by Simon Baev 21 May '15

21 May '15

Hello, I'm looking for a way to run *x2goserver* on *Ubuntu Mate 15.04* which is living on computer with *4k monitor* attached. I changed *DPI* settings in Control Center -> Appearance -> Fonts -> Details to *168* to let all applications look good when I work on that machine locally. When I connect to this machine using *x2goclient* running on another Ubuntu Mate 15.04 (attached monitor has resolution of 1680x1050, fullscreen mode) I am seeing *huge* fonts (as expected) because it also uses dpi of 168 for that remote connection. *My question*: would it be possible to run *pre-connection* (and then post-connection) script(s) to temporally change DPI to "normal" value of 96 before and recover it back to 168 upon completion of the x2go session? I guess it can be done by running "*gsettings set org.mate.font-rendering dpi 96*" command but I'm not sure where to include this command. And also I'm not sure how to protect against abnormal session termination... what if session will terminate without recovering DPI back to 168? Thanks. -- Simon

The remote proxy closed the connection while negotiating the session.
by Kjetil Fleten 21 May '15

21 May '15

I have an issue with a server, that has stopped working. I can log in with ssh, but the x2goclient gives the error "The remote proxy closed the connection while negotiating the session. This may be due to the wrong authentication credentials passed to the server." I have other x2goservers, that works fine from the same client. The affected server has been rebooted, and I have also tried to purge x2goserver and reinstalled. No resolution yet. I can see that the version on the affected server is 4.0.1.19-0~106. On the server that works, it's 4.1.0.0-0~1257. I have tried to: sudo add-apt-repository ppa:x2go/ppa sudo apt-get update sudo apt-get upgrade But it seems like the update command don't fetch the x2go-repository at all. Anyone that has ideas to resolve this ? -- best regards Kjetil

X2Go Client: Where to put RSA key for auto login on Windows
by Schmid Andreas 21 May '15

21 May '15

Hi List I'm trying to use the "Try auto login" feature on Windows, but it's not working (tested with X2Go Client 4.0.3.2). When connecting, I'm always asked for a password to open the key, but I actually didn't set any passphrase at all for my RSA key. I suspect that maybe X2Go Client does not even find the key. Which is the right location to put my RSA key in? Does X2Go Client consider any environment variables? (When I enter the actual path to the key in the "Use RSA/DAS key for ssh connection" field and unset the auto login option, the connection works.) Thanks a lot for your help. Andy

The broker presumes that desktop session commands (command=...) are given in uppercase letters. I have now added code to x2gobroker, that also allows desktop session commands to be lower or mixed case. Nightly builds should be available within the next 24h.
