Clipboard stops working
by Norm Green 11 Mar '19

11 Mar '19

Hello List, I find that the clipboard stops working after a period of time. Specifically, copying from the windows desktop to the x2go window doesn't work because x2go thinks the clipboard is empty. I am copying from emacs on Windows to emacs on Linux. It doesn't matter how many times I select and copy on windows, x2go does not pass the clipboard contents to emacs on Linux. But if I disconnect from the server and reconnect, it works, using the same emacs windows. This is with x2go client 4.1.1.1 running on Win7, but it also happened on previous x2go client versions (4.0.x) . x2go server 4.0.1.20 is running on Ubuntu 16.04 Is this a known bug? Any way to fix it? Norm Green

Connection timeout over high latency network links
by Brent Roman 08 Mar '19

08 Mar '19

I'm trying to run a remote X-session on a satellite link. The ping latency is typically 800ms. I have no trouble ssh'ing to the remote machine, but, whenever I try to connect a remote session via the x2goclient, it ends within a couple seconds with a dialog box saying: Timeout connecting to raven raven is the remote hostname. Both machines are running Debian Jessie. The x2goclient is version 4.4.1.0 Is there some connection timeout parameter that I could increase to make it possible to use high latency links? Is this fixed in newer versions? Thanks! -- Brent Roman MBARI Software Engineer Tel: (831) 775-1808 7700 Sandholdt Road, Moss Landing, CA 95039 mailto:brent@mbari.org http://www.mbari.org/~brent

Local Desktop access crashes client almost immediately
by James M. Pulver 06 Oct '18

06 Oct '18

I'm running Scientific Linux 7.4 on the server, and Windows 7 on the client. I want to access my accounts (non-privileged) local desktop remotely. I log in and select the local desktop option in the client. I get a flash of the desktop (with the wrong screen size remotely anyway - I see a small part of the desktop) and then the Windows X server crashes. x2goserver-4.0.1.20-1.el7.x86_64 X2Go Client v. 4.1.0.0 Any ideas? -- James Pulver CLASSE Computer Group Cornell University

It might be that we already have KDE5/Plasma support ...
by Stefan Baur 01 Oct '18

01 Oct '18

Hi $LIST, According to Mike#1, who currently attends DebConf in Montreal, Debian 9 + X2Go Stable + KDE5/Plasma have been shown to work together. This is a single report so far, though. If anyone is willing and able to test and confirm this, it would be highly appreciated. Another test result we'd be interested in would be what happens if you use Arctica NX-Libs and X2Go Heuler instead of X2Go Stable.

Looking for a Swedish Translator for X2Go Components
by Mihai Moldovan 06 Jul '18

06 Jul '18

Hi Our current active Swedish translator stepped down recently. On behalf of the project, I am looking for someone to replace him and continue the well-maintained Swedish translations. If you are interested to help, please subscribe to the i18n mailing list[0]. More information regarding the translation process can be found on the i18n wiki page[1]. Note that most projects also have a README.i18n file in the source code repository, detailing how translations are done. Since we already have Swedish translations, all steps for adding a new translation can be skipped.

MATE screensaver is not activated when connected via x2go

Hello all, I am working with a fresh X2Go install based on Debian 9. I recently discovered that the MATE screensaver is not activated when connected through X2Go. When I connect to the server locally, it works fine. Any suggestions? Kind regards, Jens

Keyboard doesn't work from Mac OSX to Scientific Linux 7 x2go server
by James M. Pulver 29 Jun '18

29 Jun '18

The keyboard is unusable when launching XFCE on SL7.4 via X2Go from OS X. icewm-session works fine on SL7, and XFCE works fine on SL6. We've tried different versions of the Agent with no change... -- James Pulver CLASSE Computer Group Cornell University

Hi! I wanted to run the x2go client from the command line to display the "username" and "password" fields only, like it happens when using pyHoca-GUI. The problem is that whenever my users hit the "CANCEL" button they always see the list of available sessions at the right of the window, which I wanted to avoid. I've tried a command line such as: x2goclient.exe --no-session-edit --disable-pulse --session=MYSESSION --close-disconnect --hide-foldersharing --no-autoresume --no-menu I don't want to use the pyHoca-GUI because it's too slow to start (at least in our environment) Thanks, alaxa

I had always heard that lxqt did not work with x2go but I just installed it on enso, a Linux distribution based upon Ubuntu Bionic 18.04, and it works fine. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.
