Logging x2go connections?
by Grigory Shamov 04 May '17

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?
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

Issues running firefox 45.0.2 remotely with X2go
by Rett D. Walters 17 May '16

17 May '16

Hello: I have been using x2go for a couple of years now (great product), and I have run into an issue with the latest firefox 45.0.2 (archlinux x64) in the last week or so. Firefox opens for a few seconds then crashes. Running from a bash prompt results in the following output: [15311] ###!!! ABORT: Request 131.45: BadRequest (invalid request code or no such operation): file /build/firefox/src/firefox-45.0.2/toolkit/xre/nsX11ErrorHandler.cpp, line 157 [15311] ###!!! ABORT: Request 131.45: BadRequest (invalid request code or no such operation): file /build/firefox/src/firefox-45.0.2/toolkit/xre/nsX11ErrorHandler.cpp, line 157 Segmentation fault (core dumped) The x2go client is archlinux x64, running plasma 5/Kde with latest packages. x2go client version is: 4.0.5.1-1, xorg-server is 1.18.3-1. The x2go server is also archlinux x64, running Xfce4, with latest packages. x2go-agent is 3.5.0.32-2, x2goserver is 4.0.1.19-3. xorg-server is 1.18.3-1. When run on the console of the machine that I am using x2go-client to access, Firefox runs fine under Xfce4 and xwm. The latest Thunderbird works on console and on X2Go. Problem seems to be specifc to firefox 45.0.2 and running it in an X2Go session. Firefox 45.0.1 ran fine with X2Go, backleveling will be difficult as other libs will have to be rolled back as well. Google-Chrome works fine with X2go also. Is anyone else having this issue, or have any ideas on how to address this? Thanks, Rett Walters

Cannot find 4.0.5.1 download link
by Jeffrey Zheng 02 May '16

02 May '16

On the announcement page, it says X2Go Client 4.0.5.1 was released on March 24, 2016, but I could not find the download link to it. The current link to the latest Windows release on the download page is still showing 4.0.5.0 - 2015.07.31, so can you please tell me where is the download link to the 4.0.5.1? Thanks, -- ======================= Jeffrey Zheng The words of the reckless pierce like swords, but the tongue of the wise brings healing.

X2Go Seamless Mode
by Mukul Agrawal 29 Apr '16

29 Apr '16

Hello: I am trying to connect from Windows7 machine to Ubuntu (trusty) server. I will like to use X2Go in "seamless" mode ... meaning that if I start a single application, say xterm, on Ubuntu then I want only single xterm window to show up on my MSwin7 computer.Is that possible? X2Go website says it is a Remote Desktop program, but wikipedia says that you have seamless mode and your client also seam to allow it to attach to single application.If somebody can clarify upfront if this is possible or not ... it will save me a lot of time and effort. Thanks in advance! Regards, Mukul ( https://sites.google.com/site/mukulagrawal )

Ubuntu 16.04 LTS
by Robert Dinse 25 Apr '16

25 Apr '16

After upgrading Ubuntu 15.10 to Ubuntu 16.04, I can no longer connect using x2go. Trying to use either mate or kde, it appears to try to start and then aborts and goes back to the login prompt. I upgraded x2go server and all x2go software to the most recent on the server side, no help. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.
