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. Kind Regards, Stefan Baur -- BAUR-ITCS UG (haftungsbeschränkt) Geschäftsführer: Stefan … [View More]

X2Go crashes when I run Thunderbird
by Tristan Miller 05 Apr '18

05 Apr '18

Dear all, Lately whenever I try to run Thunderbird through X2Go, the session suddenly closes. The session doesn't get suspended, since when I reconnect I need to create a new session rather than resuming the old one. I assume that the server is crashing or otherwise failing, since the client remains open. Any idea what the problem is or how I can go about diagnosing this? I'm running x2goclient 4.1.0.0 on openSUSE Leap 42.3 and x2goserver 4.0.1.20 on openSUSE Tumbleweed. Regards, Tristan -… [View More]

x2go Windows Client: Strange Issue with Screen Update
by Michael Klemm 10 Mar '18

10 Mar '18

Dear x2go-user list, I'm having trouble with the x2go Windows client on one of my machines. It seems that it misses some screen updates (see the attached screen shot). The screen was made after a I typed "ls" a few times. After I reconnect the session, the screen is updated properly once and then subsequent updates are missing again. This is on Windows 10 Pro (version 1709) and x2go client 4.1.1.1 (nightly build 2017-11-14). The error also happens with the 4.1.0 client. The server … [View More]

X2go on Zorin
by Robert Dinse 24 Feb '18

24 Feb '18

The stable build of x2go presently works on Zorin except xrandr version issues but the Nightly Builds does not. Nightly builds nxagent core dumps when the session tries to start. Got to go now but will provide more details, try to get a backtrace if I can, later when I get back. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Re: [X2Go-User] unable to start Qt/KDE apps under x2go
by Bernd Schubert 23 Feb '18

Hmm, yes, xwayland is installed, but I didn't update it yet to the version on bionic. For me it seems to be a pure qt issue on ubuntu 17.10.

Attention: All X2Go Server Admins! Upcoming major X2Go (Server) Release
by Stefan Baur 23 Feb '18

23 Feb '18

Hi! We would like to inform you that a new X2Go stable version is about to be released, most likely around March 1st, 2018. In fact, the release is already ready - we are actively holding back the binary package builds at the moment so you have a chance to react. If you have set all your servers to automatically update to new releases, we suggest that you disable this mechanism now until you have verified that the new version works for you. If, on the other hand, you test and deploy updates … [View More]

WARNING: unable to send SIGTERM to process group '9507': No such process ------------------------------------------------------------- My program offers the choice of the session mode: SHADOW or XFCE/UNITY/.... The program choice is validated by modifying the parameter command of session in .x2goclient It has worked, by I have sometimes (and often) problems to open the session in the required mode. It often, even the parameter command has been changed, opens in the last used mode, and when the session is opened, in this case, I have a notification which says that the session is restored. I have tried removing the corresponding files in .x2go, but it doesn't solves anything. Do I use the good way to close the session ? Is there another way to close it ? Is there another way to open a session, and avoid this problem or can my launching command be improved ?
