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.

Odp: opensuse client - reverse tunnel problem
by Sebastian Turzański 07 Nov '17

Hi I still experience this problem Can anybody take a look at the debug output (pastebin link below) I suspect this can have something to do with x2goclient not generating the content of ~./.x2go/etc the directory itself is not created either. https://pastebin.com/uRzQnKcc Dnia Sobota, 22 Października 2016 20:54 Sebastian Turzański <dpbasti(a)wp.pl> napisał(a) > Is anybody able to use x2go client with reverse tunel (folder sharing and/or client side printing) om Opensuse > > I get the same server with reverse ssh tunnel working perfectly well when connected from ubuntu > and failing if used from Opensuse Leap 42.1 nor Tumbleweed > > > _______________________________________________ > x2go-user mailing list > x2go-user(a)lists.x2go.org > http://lists.x2go.org/listinfo/x2go-user

ssh-keygen.exe loads the processor every time the client starts
by Max A. 07 Nov '17

07 Nov '17

Hello. I'm using a x2go server on CentOS 6.9 (the latest version from EPEL, 4.0.1.20), clients use Windows XP/7 and the latest version of X2Go Client (4.1.0.0-2017.03.11). Each time the client connects, ssh-keygen.exe (C:\Program Files\x2goclient\ssh-keygen.exe) starts with the parameters "-t rsa -b 4096 -N" "-C" X2Go Client RSA user key "-f C: /Users/max/.x2go/ssh/gen/key.fl1416 ". On not very powerful computers, this causes a delay of a few seconds with each connection and irritates users. Tell me please, if it is possible to generate this key once and for all? -- M.

Two problems: Right click delayed and audio not working
by Michael Eager 28 Oct '17

28 Oct '17

Both of these problems appeared a few days ago in what used to be a functioning X2go client/server. The server is CentOS 7, x2goserver-4.0.1.20, the client is Fedora 25, x2goclient-4.1.0.0. Previously, when I started a KDE session, the startup music would play and I was able to play sound files and have the audio on the client. Now this does not work. Running mplayer gives messages saying that it failed to initialize audio driver pulse. When I right-click on a button in email or on a web page to display a menu, the application hangs for maybe 20 seconds before the menu appears. A left-click on a menu item also has a long delay. This happens with both Thunderbird and Firefox. I can run Thunderbird remotely using "ssh -X" and none of this behavior occurs. One odd thing is that this was happening a couple weeks ago and then disappeared. I don't know what caused the problem before or what changed to cure it. Any ideas? -- Michael Eager eager(a)eagerm.com 1960 Park Blvd., Palo Alto, CA 94306

Firefox Browser Performance via X2Go - and a call for help on behalf of X2Go and Pale Moon
by Stefan Baur 28 Oct '17

28 Oct '17

[crossposting this to x2go-dev/x2go-user; please reply to x2go-dev only] Hi $LIST, there have been numerous complaints in the past about Firefox' lack of performance when used in an X2Go session, especially over WAN connections. During some extensive testing and comparison of browser engines, we discovered that setting the following three values in about:config bring some improvement to current Firefox versions: gfx.xrender.enabled (boolean) true gfx.canvas.azure.backends (string) cairo gfx.content.azure.backends (string) cairo Note that xrender support is going away soon. What we also discovered is that the KDE3-fork Trinity <https://www.trinitydesktop.org/> brings a Konqueror browser version that performs way better than Firefox, even with the above three parameters enabled. Next, we discovered an actively maintained fork of Firefox 28 - named Pale Moon <https://www.palemoon.org/>. This gives comparable performance to Trinity-Konqueror, with the advantage of being way closer to Firefox in both UI design and codebase, so pages that work fine in Firefox should work fine in Pale Moon as well - something I wouldn't want to take for granted with Trinity-Konqueror. I have uploaded two demo videos showing the performance of Firefox (with XRENDER only, not cairo) vs. Trinity-Konqueror and vs. Pale Moon: Firefox (left) vs. TDE-Konqueror (right): https://youtu.be/GfTVhX0UT8M Firefox (left) vs. Pale Moon (right): https://youtu.be/kilDivhvMZw I decided to talk to the Pale Moon developers on IRC and it turns out they plan to revamp their core component <http://personal.mattatobin.com/image/capture/c4d873f0-9048-4523-8abf-ba5763…> some time next year ("port Pale Moon to the up and coming Unified XUL Platform from the current platform code we have now"). The one person I talked to in particular, Matt A. Tobin, suggested that the drop in performance came with the drop of support for GTK2. The Pale Moon developers would be interested in keeping GTK2 support even in their new core component, but would need some cash and especially some additional manpower in the form of skilled coders. So this is a call for help: - If you're a company that uses X2Go and is interested in supporting Pale Moon development, either financially or by assigning your own coders to the project, please let me know. - If you're a professional coder interested in working on Pale Moon as long as you get paid for it, please let me know. - If you're a volunteer coder that wants to work on Pale Moon just for the greater good of all, please let me know too. -> I will be coordinating all efforts from the X2Go side of things. Any questions, suggestions, comments, etc. please follow up either in X2Go-Dev or via PM.

New guy, new OBS repo and some issues
by Hans-Peter Jansen 27 Oct '17

27 Oct '17

Hello everybody, after noticing this wonderful project, I started with a new openSUSE Build Service repo for x2go today: https://build.opensuse.org/project/show/home:frispete:RemoteDesktop:x2go since RemoteDesktop:x2go is somewhat orphaned and suffers from serious bit rot in some auxiliary packages. While at it, I've updated x2goclient to 4.1.0.1 already, and plan to update the other packages, that saw new releases, soon. Being a heavy remote user of all kinds (ssh, vnc, rdp), this project is a perfect fit. I never got NX to cooperate nicely, but always thought, that the basic concepts are sound. Anyway, I was able to install the x2goserver and x2goplasmabindings packages on a remote system (Leap 42.3 Virtualbox VM on a 42.3 host), and successfully connect to it with the x2goclient package, reaching out a nice and fresh KDE desktop. So far for the good news. After login, powerdevil crashes with signal 6 (related to non existing DimDisplay action). This in turn results in a drkonqi crash (sig 11). Probably related to these, the X2Go PLasma Bindings failed to remove the shut down and reboot actions in the K menu. Immediately logging out results in a ksmserver crash, that effectively prevents a successful log out, hence the session can only be terminated the hard way from the X2Go client UI. Parallel ssh sessions to the server appear locked at some point (not immediately after login, but somewhat later on). There are some konsole related issues, resulting in a delay by 1 to 6 seconds from any pressed key. Interestingly, xterm doesn't suffer from this behaviour. Are these effects known already? Any ideas/mitigations/workarounds? The "unboxing" experience is very nice already. The performance is great. Filing these issues as bugs starts with the question, what package they relate to? Are you guys still using a patched libssh package? Thanks in advance. Cheers, Pete

Ubuntu pulseaudio configuration
by Jamie Allen 27 Oct '17

27 Oct '17

Greetings I am using X2GO to access and Ubuntu 17 server running Mate. I am having mixed success with the redirected audio to the client (which is running pulseaudio). I can aplay soundfile.wav and it successfully plays on the client. However, pavucontrol on the server core dumps, and any application other than aplay (eg mpg123) fails to send the audio (with no error reported at the server end). I wonder if anyone could advise on the correct Ubuntu pulseaudio configuration.... or has experienced this strange partly-working situation? With grateful thanks, Jamie

X2goClient with SSH key
by Jean Tinguely 24 Oct '17

24 Oct '17

Hello, I follow this tutoriel https://wiki.x2go.org/doku.php/wiki:advanced:authentication:passwordless-ssh but it does not work. I'm on Ubunut 16.04.3 LTS with kernel 4.4.0-97-generic. When I make a ssh user(a)my.server.com it's ok, I reach my server and connect immediatly. But when I use X2GoClient then I have a message : "Connection refused". I put the path of my private key on the field path for the sessions. I don't understand. Where did I miss a step?
