I don't run anything like that normally, but I have this feeling that virt-viewer does something that might resemble a clipboard manager so it can capture the selection and send the info about it into the virtual machine. I know the virtual machine needs to be running an "agent" service to talk to the outside world via a virtual serial port (or something like that, anyway - I'm very fuzzy on the details :-). Of course I'm also fuzzy on the details about how x2go deals with selections, so that's fuzzy squared :-).

Issues with resuming session
by Bragg, Richard 16 Nov '16

16 Nov '16

Trying to move from NoMachine as new server is virtual and I'm having some issues with some programmes not resuming with correct colours. Client : 4.0.5.2 (Qt 4.8.6) Windows 7 32 bit Server info - OpenSuse 13.2 KDE 4 On intial startup it works fine. It would be good if it would, like NoMachine, always use the 4:3 moitor if attached whether 1st or 2nd display device. But I set it to use display 2 for testing. Session starts full screen as expected and I can background the screen and bring back to front. On resume : If I use the internal X server a window open then crashes. If I use the latest build of vcsvr it will start up but in a small window and this doesn't resize or rather the window resizes but the display doesn't. I move to larger monitor and the display only takes up half height.

More than emacs crashes now
by Tom Horsley 16 Nov '16

I'm sure I've run virt-manager and virt-viewer under x2go fairly recently, but some update has apparently killed lots of things sometime recently: virt-manager and virt-viewer crash when run under x2go. zooty> gdb /usr/bin/python2 GNU gdb (GDB) Fedora 7.11.1-86.fc24 Copyright (C) 2016 Free Software Foundation, Inc.

Adding old style fonts to X server?
by Tom Horsley 13 Nov '16

13 Nov '16

I use x2go frequently between my fedora linux system at work and my near identical fedora linux system at home. When using X directly on both systems I get a font path like: Font Path: catalogue:/etc/X11/fontpath.d,built-ins And the /etc/X11/fontpath.d directory has lots of symlinks to various font directories (with most of the same fonts installed on both systems). When using x2go, I see the font path is much stupider. Including explicit paths to just the misc, 100dpi, and 75dpi font directories. What the heck is the bast way to fix this so old X programs will see all the same fonts I get when I run native? Can I do something like edit /etc/x2go/x2goagent.options and add -fp catalogue:/etc/X11/fontpath.d,built-ins as an option? (On both source and target systems).

Clipboard and virt-viewer?
by Tom Horsley 13 Nov '16

13 Nov '16

On my native fedora box, if I'm looking at a virtual machine display in virt-viewer, I can use cut&paste to do something like copy the current URL from a web browser running on the host machine, and paste it into a web browser running inside in virtual machine in the virt-viewer display. If I'm connected to the same fedora box remotely via x2go, and I then display a virtual machine inside that remote x2go session, the cut&paste from fedora to virt-viewer doesn't work. Any idea what is going on here and how to make it work?

terminating suspended sessions
by Sebastian T. 04 Nov '16

04 Nov '16

After some time unclosed sessions fill all the memory on the server. It is hard to discipline users to always close sessions -they just close the client instead. Is there any more elegant way of clearing all suspended sessions then the command I have here: for f in `/usr/sbin/x2golistsessions_root |grep \|S\| | cut -c-5`; do /usr/ bin/x2goterminate-session "$f" && kill "$f";done

Segfault on some applications
by Thackeray, Neil L 04 Nov '16

04 Nov '16

I just upgraded Ubuntu from 14 to 16.04, and I really regret it now. Many things now don't work within X2go. I've completely lost KDE, which I see is a known issue, but for some reason now Firefox and many other applications don't work. I even tried gnome-calculator and it doesn't work now, but LibreOffice does. I'm not sure if it's because of the graphical toolset used or not. The most important app not working for us is Eclipse. All of the applications that don't work function fine with an exported X session, but there is just something in X2go that is keeping it from working. kernel: [12762.555968] firefox[65546]: segfault at 0 ip 00007f9d91f649bf sp 00007ffecd72a238 error 4 in libc-2.23.so[7f9d91ecf000+1bf000] kernel: [12762.572675] crashreporter[65553]: segfault at 0 ip 00007f4bf9c009bf sp 00007ffe73a9d248 error 4 in libc-2.23.so[7f4bf9b6b000+1bf000] kernel: [12787.466816] [UFW BLOCK] IN=eth0 OUT= MAC=01:00:5e:00:00:01:00:25:00:ef:46:fb:08:00 SRC=128.174.227.254 DST=224.0.0.1 LEN=44 TOS=0x00 PREC=0x00 TTL=1 ID=63656 PROTO=UDP SPT=52742 DPT=8612 LEN=24 kernel: [12800.095585] gnome-calculato[65714]: segfault at 0 ip 00007fcfab8999bf sp 00007ffd744e1ff8 error 4 in libc-2.23.so[7fcfab804000+1bf000] kernel: [13492.855643] eclipse[68620]: segfault at 0 ip 00007f4bca47c9bf sp 00007ffd8d26b2b8 error 4 in libc-2.23.so[7f4bca3e7000+1bf000]

Blowing Up
by Robert Dinse 03 Nov '16

03 Nov '16

For some reason x2go seems to be blowing up randomly a lot today. That is the session just exits without warning and when I connect the old session is gone, I can't reconnect to it. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Upcoming Deprecation of EOL Distributions
by Mihai Moldovan 03 Nov '16

03 Nov '16

Hi In order to lower resource stress when building packages, I plan to deprecate support for distributions that have reached End Of Life on September 4th 2016. This includes the following distro versions: - Debian: o 6.0 "squeeze" - Fedora o 19 o 20 o 21 o 22 - OpenSuSE o 12.2 o 12.3 o 13.1 - SuSE Linux Enterprise Desktop (not Server!) o 11.2 o 11.3 After deprecation, no new builds will be published and existing builds will be deleted from the repositories to discourage users from installing unmaintained software.

USB webcam does not work
by olafs6＠gmx.de 31 Oct '16

31 Oct '16

Hi! From my webcam (Microsoft lifecam 3000 HD) works under x2go TCE only the microphone, but no picture. I can also not check anything and come no further, since the webcam is not shown with lsusb in shell. (By the way, other USB devices are full not recognized, as my external hdd and a BlueRay drive. Via USB, only the microphone of the webcam and USB sticks works so far.) How do I get the webcam to run? Bye, Olaf

Installation Instructions for mTelePlayer/Telekinesis?
by Rudolf Mayer 31 Oct '16

31 Oct '16

Hi! First of all, let me say thanks for providing X2Go, it's really great, I am now using it everywhere instead of nomachine/freenx, which I have enjoyed using for more than 10 years.. Now, I do have a recent use-case where I'd like to play-back video over x2go, and I came across the mTelePlayer project; I saw that there are Ubuntu packages in a PPA, but I am not totally sure how to set it up - when I just start mTelePlayer on my remote x2go desktop, it just gives me this message: "No Telekinesis local socket available at: <someDir> Is Telekinesis even running?" Now, I am not sure where I have to run what; on my x2go server, I installed mteleplayer, and then also both telekinesis-client and -server. I then further installed both telekinesis also on the machine I use as a client, and opened a new x2go session - still the same message. I searched around, but couldn't find any Howto/readme. Could you help me out with some short instructions? Thanks, Rudolf

I'm trying to add a quick launcher for someone on his desktop, a Windows system. Any pointers as to how to do this? When I try to add a launcher, it launches X2go and then he has to click further. I want a launcher that just logs him straight in. I've set up certificate based login.

Desktop does not resize
by Nigra Truo 08 Oct '16

08 Oct '16

I'm having the exact same problem: http://unix.stackexchange.com/questions/233163/how-to-fix-x2go-desktop-that… Except that I erased the .kde config, to start fresh and it did not improve the situation. I also specified 800 x 600 as window size, but x2go resizes the window without me asking to do so to full display size and it is still not enough to display everything, the task bar for example (kde) is off screen. Thanks Markus -- *Por sperto kaj lerno ne sufiĉas eterno.*

Nightly Builds

Is there a nightly builds repository for Mint 18? Trying to figure out how to get things installed, it seems I've somehow managed to break perl with the upgrade from Mint 17 to 18. I've yet to have a Mint upgrade go well, I really hate the OS but unfortunately some of my customers like it. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Re: [X2Go-User] Upgrading to nx-libs 3.5.99.1
by Mike DePaulo 03 Oct '16

03 Oct '16

Hi Robert, 1. I updated the email subject to make it more clear. 2. For those who do not know, this is a reply to Robert's nx-libs 3.5.99.1 upgrade issue as listed in: http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=1089 3. Software installer is the wrong tool for the job. "dpkg -i" does not work with apt repos. It also doesn't handle dependency resolution. 4. To add this apt repo on Ubuntu 16.04, you would create a file with a name like this: /etc/apt/sources.list.d/nx-libs-beta.list ("nx-libs-beta" can differ. The folder path and the ".list" extension must be the same.) with these contents: deb http://packages.arctica-project.org/ubuntu xenial main You also run this command: wget -qO - http://packages.arctica-project.org/archive.key | sudo apt-key add - 5. To recover your system, I recommend the following: a. Run `apt-get update` b. Run `apt-cache search libnx` c. Uninstall all the libnx packages, such as by running: sudo apt-get purge <package-list> Note that this step (or the next one) will result in x2goclient and x2goserver being uninstalled. That should be OK, see step f. d. Also remove "nxproxy" if it is still installed. e. Add the nx-libs 3.5.99.1 repo from #4. f. Install x2goclient or x2goserver (+ any other client/server packages.) This should pull in nx-libs 3.5.99.1. 6. For those who are wondering why this upgrade issue can occur when using "dpkg -i" on all the nx-libs deb packages, it is because nx-libs 3.6 drops many of the X11 libraries that were part of nx-libs 3.5 in favor of the system's X11 libraries. Thus those library packages no longer exist, and the entire upgrade process needs to involve removing those libraries. -Mike On Sun, Sep 18, 2016 at 10:12 PM, Robert Dinse <nanook(a)eskimo.com> wrote: > > I used dpkg -i file, same as the software installer.

While speeds shows a 70/70Mbps upload/download testing with a server not far from here, against other in my country is much more than a 1Mbps. x2goclient refuses to connect "no data received from proxy". I've tried ISDN/MODEM/ADSL etc... -- Luciano Andino Ing. en Sistemas de Información UTN Frsf

X2goclient DPI setting
by Michael Eager 28 Sep '16

28 Sep '16

Hi -- What does the "Set display DPI" session preferences do? I have a new 4K high-dpi display (161 dpi) and I'm connecting to a remote X2go session. The window to the remote is small and any window I open in the remote has fonts scaled to 96 dpi, which makes them hard to read. In the remote session, I can set Xrdb:dpi in .Xdefaults and this helps with the font scaling issue. -- Michael Eager eager(a)eagercon.com 1960 Park Blvd., Palo Alto, CA 94306 650-325-8077

Problem running audio applications in TCE mode
by Walid MOGHRABI 23 Sep '16

23 Sep '16

Hi, I'm still struggling to make my TCE setup work correctly. I managed to fix about every bits here and there but there is still one important part that I can't get to fix which is managing audio applications to work in TCE mode. To be clear, what I call "TCE mode" is pxe booting an diskless station with x2gothinclient (per the doc setup with default settings, Debian wheezy based with heuler x2go client) When I open a X2Go session with a local x2go client on my Ubuntu laptop (or even with x2goclient under windows), no problem, I have sound with PulseAudio fully working, I can play videos on youtube, hear MP3s with totem or any other audio application. Running the same session with a TCE client works great until I want to hear a sound ... youtube videos are hanging with no sound, playing MP3s don't even start. Anything related to PulseAudio seems broken in TCE mode and this is very annoying to me because we'd like to deploy TCEs in my company to replace about 150 Windows PCs but this is for a call center so if audio is not working, this is a no go. I'm pretty sure this can be fixed with some PulseAudio configuration tuning but I must admit that I'm totally confused by PA and I don't understand a bit of the beast so any help would be gladly welcomed !

Fedora 24
by Robert Dinse 17 Sep '16

17 Sep '16

Puzzling stuff with Fedora 24 and x2go, it has the same issue as Ubuntu 16.04 with respect to xrandr being 1.2 and needing 1.3 (command line version is 1.5), yet it somehow manages to update the screen size anyway. Another problem, no /var/run/utmp entry made with x2go logins, not even if you open up a terminal. It allows me or other users to be completely invisible without examining processes. Both who and w return nothing. I am using Mate desktop with lightdm desktop manager. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Trying to get x2go working properly from NoMachine
by Bragg, Richard 16 Sep '16

16 Sep '16

Hi All I am trying to get x2go working on a virtual (headless) OpenSuse 13.2 KDE server. I have used NoMachine in the past on a hardware Workstation with no issues. It starts the session and reconnects fine when the line drops. On the new server though the graphics are slow and on reconnect the colours on some applications are incorrect, (Eclipse - white on white isn't readable). I've pulled the latest x2go client for the Windows laptop and installed x2go via Yast. Now to side track a little. I mostly use this virtual desktop from my laptop which can have 3 possible monitor situations. 1)On own - smallish widescreen 2)With internal screen and single external monitor at 1280x1024 (external is Display 2) 3)With 2 external monitors - Display 1 is the 1280x1024 I want to use Sometimes I will pull laptop from docking station effectively switching to 1) above. Then put back and need the display to be handled appropriately. NoMachine player does very well. It seems to remember where I put the display and sends to the correct monitor, even on resume. Issues Using x2go client the fonts are too big. Nomachine and PyHoca-GUI get it right. Xlsfont on NoMachine and PyHoca show thousands of entries, x2go client has around 700. I installed the fonts with the application. X2go client crashes on resume. I create session OK, full screen on the 1280x1200 monitor. On resume it tries to open a smallish window and then the xserver crashes. The PyHoca does work as intended if I use "Maximise" but then the "window" takes over the monitor and I can't easily switch to other apps on that screen and back again. CTRL-ALT-M will let me access other apps but then it's hard to switch back. PyHoca full screen tries to use both screens on laptop - not what I want. Sometimes I can't resume. I get errors about nxproxy or no permission to display in error log. Then I usually have to go to server and manually remove old session files and try to get a new session. This hasn't been an issue so far but could be if I got disconnected while editing. I really hope to get x2go to work as it seems far quicker than NoMachine in this circumstance. But I do need it to be stable and reliable. Nomachine server 3 (last one with virtual desktops) has worked great. I can resume sessions in different resolutions and on different client machines and all my programmes are there, including remote apps throwing screens back to the "workstation".

Web browser performance over X2Go
by Jordan Sokolic 27 Aug '16

27 Aug '16

Hello, I use a web frontend for work that runs locally on my server over X2Go for about one year with success. Some months ago I noticed a significant decrease in performance when using Firefox. My server is running Ubuntu 16.04 with MATE desktop, Windows 10 client. Up to Firefox version 39.0.3 performance of loading pages, scrolling, browsing etc. was nearly flawless over a 5Mbit WAN link (with the exception of embedded video elements). However it seems the release of Firefox version 40.0 introduced some changes in rendering (see https://www.mozilla.org/en-US/firefox/40.0/releasenotes/) that do not play nice with X2Go. Further reduction in performance was noticed in versions 46.0 and 48.0. The current release (48.0) even has trouble rendering a plain text document without lag and choppiness. I have tried toggling various flags relating to graphics, compositing, rendering, etc. to no avail. To work around this problem the only solution I have found is to forward ports over a separate SSH tunnel and browse locally, but this is cumbersome to set up every time I need to connect. I have preferred Firefox to Chrome over X2Go because the latter has always been unusably slow; now they are both similarly choppy and slow. Has anyone else noticed this? Any advice or help would be appreciated. Regards Jordan
