Shared Folders?
by KARL A. WOELFER 25 Jan '17

25 Jan '17

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

Scientific Linux 6 XFCE issue
by James M. Pulver 28 Jan '16

28 Jan '16

It seems that when we run XFCE or custom desktop xfce4-session, we get the same result over X2Go for XFCE - one panel, that is empty. This is not what we get logging into XFCE on the local console of the computer. Google shows this is often an issue on Ubuntu derivatives, or was several years ago. Has anyone else had this issue on RHEL derivatives? Any idea why it doesn't seem to get the expected panel settings? -- James Pulver CLASSE Computer Group Cornell University

x2go in TCE environment
by ECF Solutions 27 Dec '15

27 Dec '15

Dear all, maybe someone can give me a hint ... I tried to set up a client server solution to replace LTSP. Some Background: 1) Server - 2 CPU -> 8 Core - 20 GB RAM - 1G Network / 2 NIC - Ubuntu 14.04 LTS - VirtualBox 2) Client Futro S400 256 MB RAM or HP Thin Client HSTNC-012-TC (1 GB RAM) I set everything up according to "http://wiki.x2go.org/doku.php/wiki:advanced:tce:install" in an virtualbox (actually 2 boxes - one as "server" one as "pxe-boot-server" - both Ubuntu 14.04 server minimal) 1) "sudo x2gothinclient_update" as well as "sudo x2gothinclient_create" both end with a message that he cannot follow / write to symlink - but seems this is a minor problem 2) when I start a client he gets an IP and boots into the menu - if I choose "Thin Clint..." he further boots into the chroot and finally I get a terminal to log in. Within the chroot I gave root a password and can login. With the command "startx x2goclient" the x2goclient is started and I can establish a session and connect to my application-server. So far so good - but - I can't do this (because of x server errors as "normal user") - minor problem - everything is terrible slow - big problem - LTSP is much much faster ... - I can't change screen resolutions I made the experience that x2go is a wonderful piece of software and when I connect to my company server from outside its nearly as fast as when I work in the office via LTSP... so I assume that I made mistakes ?!? Any hints please? Why is it so unacceptable slow and I thought that I won't get a terminal and the clients would boot direct into the x2goclient window? Best regards - Christian

Ctrl key, and clipboard
by Edward Ned Harvey (x2go) 22 Dec '15

22 Dec '15

I am new to x2go. I just created my first ever x2goserver (centos 6.7 x86_64) and connected my first ever client (OSX). I'm really impressed by the speed, and ability to resize and suspend/resume. But I immediately noticed two problems: My ctrl key doesn't go across. In the remote gnome session, I launch a gnome-terminal, and I start something like ping, and when I press Ctrl-C, the other side just gets a 'c' character. I don't see any way to press Ctrl-C or Ctrl-D and so on. The second problem is the clipboard. Although I have the option selected for bidirectional clipboard, when I copy something on the remote side, it doesn't appear in my local clipboard. I didn't test copying something locally and pasting remotely ... If you want, I can do more testing. The client crashes a lot when you make changes to the session config - but I don't care about that as long as it's reliable during normal usage. Thanks for the development of x2go! Is it ready for production yet? Are these things expected to work yet, or is it something for me to just watch for future usage? Thanks again...

sessions won't die
by Michael Stauffer 22 Dec '15

22 Dec '15

x2goagent: 3.5.0.31x2goserver: 4.0.1.19x2goserver-extensions: 4.0.1.19x2goserver-xsession: 4.0.1.19 CentOS Linux release 7.1.1503 (Core) Hi, I've had this issue before but haven't figured it out. It still happens once in a while - I get sessions that won't die after calling x2goterminate. Here's one that's stuck now: 1174|asharma-62-1450478577_stRPUBLISHED_dp32|62|cx2go.uphs.upenn.edu |R|2015-12-18T17:42:57|e016e30d1277cccb5d7360cc8760c01f|170.212.109.160|30045|30046|2015-12-18T17:43:27|asharma|247541|30047| Furthermore, there's no process 1174 running, and the user asharma isn't running any processes either. This user is currently having trouble starting a new session, and I don't know if it's related to this or not. Anyone have any suggestions? Thanks. -M

keys not being passed from MacOS client to x2go session?
by Grigory Shamov 21 Dec '15

21 Dec '15

Hi All, This is probably a trivial question: I have installed x2go server, from EPEL, on CentOS 6.6; I'm using Gnome for the desktop. The problem is when I connect using x2go client for older MacOS (i'm on 10.7) some key combinations apparently do not go through. Like, Ctrl+C or Escape or Shift+Ctrl++, all not working. On Windows VM the Windows x2go client works ok. Are there any settings for MacOS x2go clients that can be used to fix it? Thanks! -- Grigory Shamov Westgrid/ComputeCanada Site Lead University of Manitoba E2-588 EITC Building, (204) 474-9625
