x2go client GUI does not display on Windows 10
by Gladia Hotan 25 Jan '18

25 Jan '18

Hi, When I run x2go client on windows 10, the icon pops up on the taskbar and the process is running, but the GUI window does not display. I tried uninstalling and reinstalling several times and also tried the suggestions at this link <https://askubuntu.com/questions/593046/x2go-client-not-showing-gui>, but the GUI still does not appear. I also tried changing my screen resolution in case the GUI window was being drawn offscreen, but the GUI still does not appear. How can I troubleshoot this further? Best, Gladia

qt5 application window not rendered
by Bernd Schubert 25 Jan '18

25 Jan '18

Hi all, somehow qt5 application windows are not rendered anymore. I think this came with the upgrade to ubuntu 17.10, but I'm not totally sure. My desktop is xfce and I only rarely run qt applications - I recently noticed that qgit is broken and then noticed that not a single qt5 programm works. Applications linked to qt4 seem to work fine. So when I run qt5 programs, it brings up window, but this just shows whatever was under that new window, but not the real not content. Outside of x2go it works fine, of course. I also just updated x2go to the unstable nightly (Version: 2:3.5.99.12-0~201801110901~ubuntu17.10.1), same result. Before updating to the nightly build, it complained about xkb errors when I started qt5 programs, right now nothing except a gtk2 warning comes up. Is there any way to trace what is going on? I'm rather clueless about X debugging. Thanks, Bernd

What are athe difference between connexions
by Alain Aupeix 19 Jan '18

19 Jan '18

Hi, I have made a maintenance tool to easily connect to distant or local computers with different products like vnc, x2go, ssh connections, ... For x2go connexion, I use this command line: cmd="x2goclient --thinclient --kbd-type=pc105/fr --autologin --link=lan --clipboard=both --close-disconnect --session="+trim(sUser)+"@"+trim(sMachine)+" &" To change the connection type, I first modify command in .x2goclient/sessions before connecting If I connect changing command to XFCE, it works directly If I connect changing to SHADOW, if works, but x2go ask me for : display :0 or display :50 , and also if I want complete access (what I want) If I choose 0, it works, and also with 50, but in this case, no shared display as with XFCE In .x2go folder, I have this files : S-alain-50-1516374453_stDXFCE_dp24 which is generated by XFCE connection S-alain-51-1516383729_stS1XSHADalainXSHADPP0_dp24 which is generated by local connectiondisplay :0 S-alain-51-1516383880_stS1XSHADalainXSHADPP50_dp24 which is generated by local connectiondisplay :50 What are the differences between XFCE and local :50 connections ? Is there a way with some parameters to launch directly x2go local session ? Another minor problem: When I open a session from my desktop (1280x1024) on a notepad which has a screen of 1440x900) with x11vnc, I apply a correction of the screen size (about 0.88 for this computer) to have a complete display of the server screen. Is there a way to do such thing with x2go ? I have found the .x2goclient/sizes. [mainwindow] size=@Size(1175 747) pos=@Point(94 113) maximized=false Can I change it in this file or is it better to change it in .x2goclient/sessions ? Thanks for this nice product.

x2go local desktop connection on rpi
by RW 19 Jan '18

19 Jan '18

Hi, I've recently been trying to use X2go to connect to a Rpi3 running the latest ubuntu mate 17.10 This seems to work when selecting xfce or a new session but doesn't work when trying to connect to the local desktop (which is already logged in) I even tried installing / running x2godesktopsharing on the server side then enabling shared desktop, but that didn't have any affect (I think that's only needed for different users normally) * client - Windows 10 / latest X2go client 4.1.0.0 * server - Rpi3 / Ubuntu Mate / latest x2goserver 4.0.1.22-0~1197~ubuntu17.10.1 It just seems to jump out with the following message on the client "The connection with the remote server was shut down. Please check the state of your network connection" * I was able to rule out the client as the problem by connecting from windows to a x64 gentoo vm / local desktop vm which worked fine on the local desktop setting (same version 4.0.1.22 server) * I also tried connecting from a linux client to the rpi but with same results * For the rpi as the server, this only seems to affect connections to the local desktop, connections using a new session in the drop down work okay Logs attached below any ideas on how to get this going? one difference I've spotted with a working setup is the message "state file for this session does not exist" in the server logs client log: NXPROXY - Version 3.5.0 Copyright (C) 2001, 2010 NoMachine.

My client is a 2017 MacBook Pro running the latest X2go client v4.1.1.1 (Qt 4.8.7) and XQuartz 2.7.11. It works pretty well. It runs at fullscreen, 72DPI by default. The fonts are a little tiny. It's a little bit laggy, but it's a development/mediaserver machine in my basement. Just wanted to report the success. One question I've been unable to find a (current) response to is this: is there a way I can suspend my x2go connection rather than logging in from scratch each time? I've got some apps I'd like to leave running on the KDE machine when I'm not connected. I've seen references to a command like "x2gosuspend_session" or something similar, and tried it. I still started from basic login. Even the "pause" button in the OSX client restarts the session. My apps reopen, but my all my Firefox tabs have closed and my terminal windows are blank. Any suggestions?

Ubuntu Nightly Builds Server Problem
by Robert Dinse 14 Jan '18

14 Jan '18

After installing updates today Ubuntu 17.10 server with x2gonightly builds now will not allow me to connect. When I try I get a pop-up that says: Connection failed. /usr/lib/x2go/x2gogetrandomport: line 106: get_random_port: command not found Unable to get (pseudo-) randomized starting port value. The stable build still works except the xrandr version issue which was why I have been using the Nightly Builds on Ubuntu. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

colors of qt5 apps wrong?

I've recently seen problems where colors are totally wrong on some apps. First it was matplotlib. Now I see it on tortoisehg. Both I believe are QT5. Any ideas?

empty published applications list
by Michael Stauffer 07 Jan '18

x2goagent: 3.5.0.32 x2goserver: 4.0.1.20 x2goserver-extensions: 4.0.1.20 x2goserver-xsession: 4.0.1.20 CentOS Linux release 7.4.1708 (Core) Hi, I recently updated my x2go server. Now x2go clients get an empty list for published applications. The one symlink I have in /etc/x2go/applications was bad, so I redirected it: [root@cx2go ~]# ll /etc/x2go/applications/ total 0 lrwxrwxrwx. 1 root root 23 2018-01-06 21:41 gnome-terminal.desktop -> /usr/bin/gnome-terminal /usr/bin/gnome-terminal itself runs In /var/log/messages, I saw ‘x2gogetapps has been called without options” Here's what it returns: [root@cx2go ~]# x2gogetapps <desktop> </desktop> Anyone have any suggestions?

Switching workspaces
by Blake McBride 03 Jan '18

03 Jan '18

Hi, New x2go user. Wow! And thanks! Both my server and client are running x2go 4.1.1.0 and both are 64 bit LinuxMint/MATE. I have two monitors on the client. Mostly, everything works great except I have two problems: 1. When I chose full screen with Xinerama extension it comes up exactly the way I want on both screens. The problem is, I want to be able to switch workspaces on the client host but every time I do it changes workspaces on the client client instead. I tried remapping the Ctl-Alt left and right on the client client, but that didn't matter. How can I switch workspaces on the client host? 2. If I select "Use whole display" (1 or 2), I only get the upper left 25% instead of the entire screen 1 or 2. (This used to work in 4.0.1.1 but I had other problems with that). I really appreciate any help you can offer. Thanks! Blake McBride

Lightdm invalid MIT-MAGIC-COOKIE-1
by May Doušak 01 Jan '18

01 Jan '18

Hi there, I have a problem with a machine that rebooted due to power outage. Debian, lightdm, XFCE. If I want to use the X2go, I need to login locally in lightdm on the server first - if I don't, I get an error of "invalid MIT-MAGIC-COOKIE-1: keyxwininfo: error: unable to open display :0" when I try to login thru x2go remotely. Does anyone have an idea how to make it work without first logging in (=driving there) locally? ps aux | grep X root 1353 0.2 0.7 368172 59736 tty7 Ssl+ 18:25 0:01 /usr/lib/xorg/Xorg :0 -seat seat0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch xauth list (returns nothing) Thanks, May

Ubuntu 17.10 x2goserver
by Robert Dinse 22 Dec '17

22 Dec '17

I removed the nightly build and went back to the main line x2goserver and this works except for the xrandr version issue. I still have to set the screen size manually with xrandr -s 1920x1080 but then I can use the entire desktop. It's a pain but at least servicable. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

New x2go broken on Ubuntu 17.10
by Robert Dinse 21 Dec '17

21 Dec '17

Recent updates to x2go seriously broke it on Ubuntu 17.10. After the update, the first attempt to login resulted in giant fonts, giant terminal windows, giant everything. I went into System->Preferences->Look and Feel and then Fonts, then Advanced and found DPI had been set to 201, set that back to 96 and font size and terminals returned to normal, but I can't use the bottom half or approximately right third of my desktop now. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Having a problem with connecting to remote desktop in Windows
by Kadyrbek Narmamatov 20 Dec '17

20 Dec '17

Hello all, Getting this message while trying to connect to remote desktop: [image: Встроенное изображение 1] I press `Yes` button, but it cannot do anything and asks again this question. I suppose that this message is most probably because of ssh trying to save my machine as `known host` in configuration and not able to find appropriate path for saving the file, because I don't have any problem while connecting with linux machine.

Two servers - one adjusts resolution, the other does not?
by May Doušak 19 Dec '17

19 Dec '17

Hi, I have two machines with x2go server. Both are "debian unstable", both are running XFCE, both have x2go-server 4.0.1.22. But one adjusts resolution according to the window size while the other does not. The server that *does* adjust adds new mode into xrandr mode tables, e.g. 1436x865: xrandr: Failed to get size of gamma for output default Screen 0: minimum 320 x 240, current 1436 x 865, maximum 6400 x 1602 default connected 1436x865+0+0 0mm x 0mm 1920x1200 60.00 (....) 1920x1080 60.00 6400x1602 60.00 1436x865 60.00* may@Dell:~$ The other does not, it only lists modes that monitor can accept, the image is scaled to window size (super-ugly). Same goes for copy-paste - but I have same settings in X2go client for both. Any idea on what should I check? Thanks, May

Yes, this has been an issue for a long time, for csh-based shells anyway. http://lists.x2go.org/pipermail/x2go-user/2015-October/003550.html If you read through that thread, we did find a decent workaround – putting some logic in .cshrc to load the correct keyboard mapping. Darby

I am trying to install the nightly build on Mint Sylvia 18.3, but there is no 'sylvia' in the repo so I tried to install stretch. I've build the nx-libs and installed them without error but attempting to install x2go from stretch (18.1) on sylvia (18.3) results in: apt install x2goserver Reading package lists...

Sorry for the previous mail, blame my thick fingers. Heres the complete mail. Hi everybody, I'm new to x2go and I am trying to set up a thinclient environment and I try to build the live netboot image. I've been following the instructions in https://wiki.x2go.org/doku.php/doc:howto:tce#starting_the_build I did set the following export LBX2GO_CONFIG='https://github.com/LinuxHaus/live-build-x2go::feature/openbox-magic-pixel-w…' export LBX2GO_ARCH='-a amd64 -k amd64' export LBX2GO_SPACE='--apt-indices none --apt-recommends false --cache false --checksums none --firmware-binary false --memtest none --win32-loader false' export LBX2GO_DEFAULTS="--backports true --firmware-chroot true --initsystem sysvinit --security true --updates true --distribution $LBX2GO_DEBVERSION" export LBX2GO_ARCHIVE_AREAS="main contrib non-free" export LBX2GO_LANG='de' export LBX2GO_TCE_SHRINK="true" export LBX2GO_NOSQUASHFS="false" export LBX2GO_IMAGETYPE='netboot' When I run the build script on a debian stretch system (9.2) I run into the following error ...

Client connection not possible

Hi, I reinstalled a machine (SLES 11 SP3) and used the repo http://download.opensuse.org/repositories/X11:/RemoteDesktop:/x2go/SLE_11/ for installing x2go. When I try to connect a session seems to be started, but is closed immediately. There is no helpful log in the moment (see below). Any idea how to check the setup ?

"The remote proxy closed the connection while negotiating"
by Andrew Munn 11 Dec '17

11 Dec '17

I keep getting this message from my x2goclient "The remote proxy closed the connection while negotiating the session. This may be due to the wrong authentication credentials passed to the server." I am shown the usual "Select session:" dialog box with columns display, status, command. And also the normal buttons suspend, terminate, new, resume, cancel. There is 1 session listed. I double click on it and get the error. But the password is correct. I can ssh into the session with no problems. I think this error occurs because I recently deleted x2go related directorys in /tmp or ~/ on the client machine. Is that possible? And if so could we make the error message more helpful? I have uninstalled and re-installed x2goclient including the ~/.x2go* dirs and it does not fix the problem. I'm seeing this in /var/log/secure: Dec 11 12:56:47 herc sshd[60805]: error: connect_to localhost port 59700: failed.
