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.

Heads-Up: X2Go: The Gathering 2018 (2018-11-09 - 2018-11-11) will very likely take place at Stuttgart's hackerspace "shackspace"
by Stefan Baur 30 Aug '18

30 Aug '18

Dear $ALL, since nobody has replied to the call for volunteers for the IT-Kongress event (see <https://www.mail-archive.com/x2go-project@lists.x2go.org/msg00278.html>), and since we've lost a sponsor, compared to the previous years, it is very likely that X2Go: The Gathering 2018 will have to take place at Stuttgart's hackerspace "shackspace" (<https://shackspace.de/>) - "will have to" meaning that we're out of suitable alternatives due to both time/volunteer staff as well as financial constraints. Thus, there will be no voting period regarding the location this year, we'll simply have to pick the only option that seems to be left at the moment. The last-resort fallback option would be Ulm's youth hostel (both as an event location as well as for sleeping arrangements), but this would mean groups of 4 people would have to share one room, as they do not offer smaller rooms - which, judging from previous years' feedback, is not a situation most of our participants would be happy with. This is why we're not offering a poll with Stuttgart and Ulm as options. For Stuttgart, we're looking at a hostel-like place that offers single and double rooms, as well as at a hotel nearby, for people that prefer a higher-quality sleeping arrangement. Details will be published on the Wiki at <https://wiki.x2go.org/doku.php/events:x2go-gathering-2018> as soon as the two sites have confirmed room availability and replied with their booking cancellation terms.

keyboard layout driving me insane
by Neal Becker 27 Aug '18

27 Aug '18

On client side, I have layout set to map caps lock to ctrl. I need this also when using x2go! But it seems hard to achieve. In x2go, I try both 'autodetect keyboard' and 'don't configure keyboard'. I try mate, xfce, lxde. On the server side I would like to try also configure keyboard layout, but I don't find any good way to do it on those window managers. Unfortunately, neither KDE nor GNOME will work (both client and server are fedora 28). Sometimes I seem to hit a combination that works, but then when if the connection is terminated and I try again, it's once again not preserving my key remapping. This is driving me nuts! Any recommendations?

x2go client users don't show up in "users" or "who" (Ubuntu 18.04)
by Alan Broder 26 Aug '18

26 Aug '18

When users connect to our server via ssh or mosh, the "users" or "who" command work properly, and you can see the list of logged-in users. However, when users connect via the x2go client (from Windows or Mac) - they do not appear in either "users" or "who". Has anyone observed this problem and know how to fix it? Alan
