Logging x2go connections?
by Grigory Shamov 04 May '17

Hi All, This perhaps is a trivial question: but is it possible to somehow log/check history of past x2go session on the server? -- Grigory Shamov Westgrid/ComputeCanada Site Lead University of Manitoba E2-588 EITC Building, (204) 474-9625

Shared Folders?

I am not able to get the basic Shared Folder capability to run. Debian 7 Linux OS on client and server, X2go V 4.0.3.0, and XFCE Desktop. Is there something fundamental preventing this from working? Thanks in advance, - KarlW

Num Lock key in windows agent
by Olivier BILHAUT 24 Nov '16

24 Nov '16

Hi all. First of all, I'd like to congratulate all the contributors for this great work. X2go is a professional class tool for remote desktop. However... I ran into a really special thing using the windows agent in its last version (4.0.5). Sometimes, when you open the session, the "Num Lock" is usable, sometimes not. I mean, sometimes you may push the caps lock button and switch from arrows to Numeric keys, and sometimes the Key Pad is fully unusable. It happens only on windows agent as far as I know. All that I tried did not solve the issue. Did you already encounter that? Thanks. -- OB SySAdmin Fondation Hospitalière de la Miséricorde

x2goclient session icons not working
by Will Wagner 23 Nov '16

23 Nov '16

Hello, I have upgraded to 4.0.4.0 on win32. It's a minor thing but if I now set a session icon for a connection it is not displayed and I get blank instead. Is there something I need to do to get this to work? Thanks Will

Video
by Orion Poplawski 30 Mar '16

30 Mar '16

I'm having a lot of trouble getting a gstreamer based video player to work under X2Go. First off it looks like Xv is not supported. Is that something that ever will be? Next thing I'm seeing with the parole player is that the video frame goes black when I pause it. I'm also trying to use the fluendo gstreamer codecs and seeing segfaults (apparently in the fluendo code) when using dragon player to watch videos. I'm running with current nx-libs git from https://github.com/ArcticaProject/nx-libs. EL7 server and client. Any ideas or suggestions? Thanks. -- Orion Poplawski Technical Manager 303-415-9701 x222 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion(a)nwra.com Boulder, CO 80301 http://www.nwra.com

x2go overwrites LD_LIBRARY_PATH
by Thomas Stephan 11 Mar '16

11 Mar '16

Hi, I am using x2go to connect to machines running Ubuntu 14.04.3 LTS. I had trouble running commands that rely on finding libraries via the environment variable LD_LIBRARY_PATH. LD_LIBRARY_PATH is set in a script in /etc/profile.d because this is a system wide configuration and it needs to be performed once per login. Using ssh to remote login, LD_LIBRARY_PATH is correct: echo $LD_LIBRARY_PATH /usr/lib/fsl/5.0 When I login using x2go, LD_LIBRARY_PATH seems to be reset and contains only the entries regarding x2go: echo $LD_LIBRARY_PATH /usr/lib/nx/X11/Xinerama:/usr/lib/nx/X11 My guess is that there is probably an error in /usr/bin/x2goruncommand, along these lines: test -n "$LD_LIBRARY_PATH" && \ LD_LIBRARY_PATH="$NX_XINERAMA_LIBS:$NX_LIBS:$LD_LIBRARY_PATH" || \ LD_LIBRARY_PATH="$NX_XINERAMA_LIBS:$NX_LIBS" "$X2GO_LIB_PATH/x2gosyslog" "$0" "debug" "exporting LD_LIBRARY_PATH=$LD_LIBRARY_PATH" export LD_LIBRARY_PATH But I can not see why it is that my path only contains $NX_XINERAMA_LIBS:$NX_LIBS, and not $NX_XINERAMA_LIBS:$NX_LIBS:$LD_LIBRARY_PATH. Thank you for your help!

x2go-client depends on xorg-xauth?
by Bruno Pagani 09 Mar '16

09 Mar '16

Hi, I’m currently using x2go-client on a (Arch) Linux desktop (connecting to a Ubuntu x2go server, on which I’m not admin), and I’ve found out that it apparently needs xorg-xauth to work properly. Is that indeed the case? Because I can’t found a list of dependencies outside of nx, qt4 and libssh, and the current ArchLinux or Fedora packages (for instance) do not depend on it. Thanks, Bruno P.S.: Since I’m not suscribed to this list, please be sure to keep me in CC when you answer this. ;)

Reconnect to session
by Michael Eager 09 Mar '16

09 Mar '16

Hi -- I'm trying to reconnect to an existing session using the x2goclient GUI, or using the pyhoca-cli command line. This does not work. I'm also not able to suspend a running session. When I use x2goclient to re-connect to a server, the old session is listed as running. This is also displayed by the CLI: $ pyhoca-cli -L --server qc pyhoca-cli[18645] NOTICE: preparing requested X2Go session pyhoca-cli[18645] (PyHocaCLI) NOTICE: preparing requested X2Go session pyhoca-cli[18645] (x2gosessregistry-pylib) NOTICE: registering X2Go session Pyhoca-Client_Session... pyhoca-cli[18645] (x2goclient-pylib) NOTICE: initializing X2Go session... pyhoca-cli[18645] (x2gocontrolsession-pylib) NOTICE: connecting to [qc]:22 pyhoca-cli[18645] (x2gosession-pylib) NOTICE: SSH host key verification for host [qc]:22 with SSH-RSA fingerprint ,,32:90:4a:a5:9e:ee:a6:0a:c9:6a:8c:b5:b3:64:0c:28'' initiated.

When I tried to connect to the suspended session, nothing happened. The GUI went blank and no X screen was displayed. Questions: 1 -- How can I connect to a session which is marked as running? 2 -- How can I suspend a session which is running? 3 -- How can I connect to a suspended session on a server? 4 -- How can I specify the session to connect to using the pyhoca-cli CLI?
