Broker with multiple hosts on different ports
by Warren, Daniel 14 Sep '15

14 Sep '15

Greetings, I am setting up x2gobroker with multiple backends, and while I can change the port that they all use for ssh, I would need to set a different port per host to NAT them to the same public IP . Is there any way to do this at present ? where can I look for documentation? -dan

Questions regarding mate/video quailty
by Harald Heigl 13 Sep '15

13 Sep '15

Hi everyone, I have following szenario: - server: Fedora 22 with gnome 3.16 (and mate) - client cubietruck (mini client like raspberry) - connected via 1Gb-LAN-cable - using LAN quality and no compression (but I also tried 16MB-jpg with no difference) 1) As I read in the docu, gnome 3.12+ is not supported, are there any plans in the near future? 2) After installing mate on the server, I didn't see an option "mate" on the client (4.0.1), only gnome, kde, lxde, xfce, so I choose "other desktop" (don't know if it's called exactly so, cause I have a german interface) and mate-session as parameter. Is this the correct way to use mate? 3) And this is my main point: Working seems to be fine so far, but when I start a video in mate (over x2go) it opens "parole media player" (seems to use gstreamer) and it says: "gstreamer backend error - Configured videosink video is not working". If I start videos with vlc they come up but are really slow und showing only each 5 seconds or so. If I use nomachine v4 they are not as fluent as if I sit in front of my "server", but at least they are acceptable. I don't have the gstreamer problems there. Is there something I can configure, does someone know this problem? videos I tested with are h.264 encoded if that matters. Thanks in advance, Harald

Problems with x2go
by Chris 13 Sep '15

13 Sep '15

Hi, I'm a long-time VNC user trying out x2go after many people have recommended it, but I can't get it to work well when trying to set up x2go-sessions from Windows, so if anyone can help me out, I'd be grateful. Issue 1: First I tried "X2Go Client" and that one just keeps crashing on me. I only need to enter the "session preferences" dialog and as soon as I press ok (independent if I change anything or not), the program crashes and Windows tells me "x2goclient.exe has stopped working". Similar crash if I try to start a session. This with X2Go Client v. 4.0.5.0 (Qt - 4.8.6) on Windows 7. I tried an older version 4.0.2.x which did not crash so there seems to be something off with the most recent version. Known issue? Issue 2: So I installed PyHoCa-GUI instead. That one is stable and mostly works. But when I choose "custom command" as the session, it refuses to run any command with an absolute path and only accepts things in places like /usr/bin/. Perhaps it is some path-issue, but it also does not accept things in /home/myname/bin/, which is in my $PATH from the shell. Note: I'm using zsh as my login shell. Is this a bug or am I not supposed to be able to run things with absolute paths? (note: I have double-checked file permissions and the things I'm pointing to under /home are +rw for everyone). I don't want to have to put my session script in /usr/bin/ Question 1: No matter if I use the "X2Go client" or "PyHoCa-GUI", I don't get the keyboard behavior I would like. Using VNC, it will just map each keypress from Windows and pass those symbols into the server, which is important since I use a custom keyboard definition. That doesn't seem to work with x2go as I get pc104/us both if I tell it to "do not set" or "automatically detect". And if I choose "use custom keyboard", I can only select a "standard" keymap, I have no idea how to tell it to use a custom keymap. Is it so that x2go can't handle user-defined keymaps and only handles standard keymaps? Question 2: Font handling. I don't get the same set of fonts when I run through x2go as I get when using VNC as some directories are missing from the font path. Trying to manually add those from inside the x2go session ("xset +fp /some/path/that/works/in/vnc/") gives an error. Is there something special with the font handling in x2go that is not compatible with all X11 fonts? Running the same xset command from inside VNC succeeds without problem on the same machine. Version info: the server is running on a Ubuntu machine (14.04) with these x2go libs: x2goagent: 3.5.0.32 x2goserver: 4.0.1.19 x2goserver-extensions: 4.0.1.19 x2goserver-xsession: 4.0.1.19 TIA, Chris

Hi dears, I'm new to XGO TCE and following this tutorial http://wiki.x2go.org/doku.php/wiki:advanced:tce:install and everything works fine from the installation of the X2GO server and X2GO PXE server to the boot process of the thine clients BUT after the thine client boots its asks for a username and password. I'm NOT using LDAP for authenticating the thine clients so i tried to create a session for the thine client by editing the file " x2gothinclient_sessions " BUT i do NOT know which parameter i need to change to set the username and password for the thine client authentication and how to associate this configuration with the client MAC address ? so can someone explain that please....Thanks in advance...

x2gobroker suspend mode
by CORDIER Nicolas NEURONES IT 07 Sep '15

07 Sep '15

Hi, Sorry to my English .. I just finish a x2gobroker configuration with 2 x2goserver under RHEL 6_x64 associated with postgres databases. Broker works well to connect on each other but when we use "suspend mode" , x2goclent close windows and we can't access to suspended sessions. If I look in the databases the session status is ok on "s" , and a x2goclient direct access ( without broker) show me suspended session. What wrong , do I need to add options agent on the x2gosbroker-agent configuration ? Thanks Nicolas. Nicolas CORDIER Infogérance CEA CADARACHE Equipe Unix-Linux 0442257952

Running application for multiple users
by Peter Schulz 05 Sep '15

05 Sep '15

I have set up x2go on an Ubuntu 14.04 machine, and it connects and creates a new session fine. However, when I have the first session running an application like Firefox or Thunderbird, then have a 2nd user log in, the 2nd user cannot run Firefox. He gets a message "Firefox is already running". I thought I can connect with multiple users to the same host? It would not be useful if I can only have one connection. Or do I need a session broker for that? Regards Peter

Ctrl+Alt shortcut does not pass into Linux
by Myrice Li 01 Sep '15

01 Sep '15

Hi All, I am using x2go under Windows 7 with the latest VcXsrv. I connect to an Arch server and mainly using Emacs. In Emacs there are shortcut keys like Ctrl+Alt+A and Ctrl+Alt+K. But it seems like Emacs does not aware of these keys. I found I need to change the default shortcut by changing the ~/.x2go/config/keystrokes.cfg So I changed them to the Ctrl+Alt+Fn key like: <!DOCTYPE NXKeystroke> <keystrokes> <keystroke action="close_session" Control="1" AltMeta= "1" Shift="1" key="F4" /> <keystroke action="switch_all_screens" Control="1" AltMeta= "1" key="F11" /> <keystroke action="minimize" Control="1" AltMeta= "1" key="F4" /> <keystroke action="resize" Control="1" AltMeta= "1" key="F10" /> <keystroke action="defer" Control="1" AltMeta= "1" key="F3" /> <keystroke action="ignore" Control="1" AltMeta= "1" key="F12" /> <keystroke action="force_synchronization" Control="1" AltMeta= "1" key="F5" /> <keystroke action="debug_tree" Control="1" AltMeta= "1" key="F6" /> <keystroke action="regions_on_screen" Control="1" AltMeta= "1" key="F9" /> <keystroke action="test_input" Control="1" AltMeta= "1" key="F1" /> <keystroke action="deactivate_input_devices_grab" Control="1" AltMeta= "1" key="F2" /> <keystroke action="fullscreen" Control="1" Shift="1" AltMeta= "1" key="F10" /> <keystroke action="viewport_move_left" Control="1" Shift="1" AltMeta= "1" key="Left" /> <keystroke action="viewport_move_up" Control="1" Shift="1" AltMeta= "1" key="Up" /> <keystroke action="viewport_move_right" Control="1" Shift="1" AltMeta= "1" key="Right" /> <keystroke action="viewport_move_down" Control="1" Shift="1" AltMeta= "1" key="Down" /> </keystrokes> Even after doing this, the Ctrl+Alt+A does not work still. But it seems this file actually take effects. Because the Ctrl+Alt+F does not work like before. Can you give me some hint for this?
