Thin/Zero-client solution with desktop feel (video streaming)
by Lars Bonnesen 28 Apr '17

28 Apr '17

Having a setup where I would like to run 10-20 zero-clients (like ThinStation). Users would like to connect to a Windows desktop and stream various videos from services like youtube. I have been setting up ThinStation where a number of test PC's boots directly into FreeRDP and connects to a Windows 2016 RDS-server. It works well except for the streaming part. One single client in full screen fills up 100% of two of the Win2016 RDS 4 Xeon CPUs! I am aware of MS' RemoteFX but this requires HyperV. We are running VMware, and for this, you will have to use Horizon and PCoIP/Blast. Only... the license price for this is simply outrageous. As we would like to keep our VMware virtualization, going to MS' HyperV is something we would be very sad about just because of this. I have been working with NoMachine before, and as I remember, it worked very well with video streaming from the NX client... I was going to try this again, but reading about it, I found numerous places where people wrote "Hey!!! No, no, no... try x2go instead... this is a fork of NoMachine". Ok... this was what I did then. Installed x2go on a CentOS, downloaded the x2go client only to experience that streaming like with FreeRDP and RDS work just as bad. Apart from this, I really liked x2go, and if I am able to get a much better desktop feel with full screen streaming, I would definitely force our users to use this Open Source solution instead. Can anyone in here suggest a way to setup x2go to perform better with streaming like if we used a setup that could handle H.264? Regards, Lars.

Ubuntu-Mate 17.04 Zesty x2go server borked
by nanook＠eskimo.com 26 Apr '17

26 Apr '17

On a fresh install of Ubuntu-Mate 17.04, after doing updates but before installing any other software other than that which installs by default, I installed x2goserver, x2goserver-xsession, and x2goclient per the instructions on the x2go website. The client works fine, the server has the normal issue with modern Linux's wanting a newer version of xrandr and gives me a 800x600 window even if I specify the full display 1. I can resize the screen using xrandr -s 1920x1080 from a terminal window. I tried installing the Arctica Libs for xenial, this worked on servers which I installed as older versions of Ubuntu and upgraded online but does not work for a fresh install. Doing so results in a disconnect before the screen is drawn. At someone's suggestion here, I built nx-libs from source on Zesty and installed, still disconnects before drawing screen. It does give a small screen which then expands to the full screen size but is black save for the letters X2GO, but it disconnects before drawing the desktop. This is using Mate, the 18.01 version that ships with Zesty. I have attached to files of the output of x2goclient --debug, x2go-debug-good-server.out is what happens when I connect to an x2go server on Zesty 17.04 that has been upgraded from an earlier version and has the xenial arctica nx-libs installed and works. x2go-debug.out is when I connect to the server where I've built the Arctica nx-libs from source, they are version 3.5.99.6-0.1. Thanks for your help.

x2goserver on Ubuntu 17.04 Zesty
by Robert Dinse 25 Apr '17

25 Apr '17

I have not been successful at getting x2go to work consistently on machines I have upgraded to Ubuntu 17.04, oddly it works on some and not others. I have two machines on which it appears to work fine and two which it does not, one of those it just gives me a black screen and the other it immediately exits. On the machine that it immediately exits it prints some error messages but the client exits too fast to read them. I can't figure out if and where x2go logs erros. I do see some things in the syslog but indicates it is starting the session successfully when obviously it is not. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Ubuntu 17.04
by Robert Dinse 25 Apr '17

25 Apr '17

On a machine that x2go was not working, I did a fresh install of Ubuntu Mate 17.04 then only did upgrades. Then I installed x2goserver, x2goserver-xsession, and x2goclient. It worked except that it gave me an 800x600 screen unless I manually reset it using xrandr -s 1680x1050 from the command line. I then installed arctica project Sunweaver's Net nx-libraries, and now it exploded when it tried to connect. I backed out those libs and it worked again. So something has changeed, yet, on two other machines I have arctica project's libs installed and all is well. The only difference is that those machines started out life as 14.04 and were upgraded in place to 17.04, as opposed to being fresh installs. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

x2goserver can support mutliple clients?
by Randell Palmer 19 Apr '17

19 Apr '17

I have setup a x2goserver and 2 x2goclients : client1 & client 2 Either of the clients will work when it is the only client receiving service from the x2goserver. I can connect one of the x2goclients, client1, to the x2goserver and it will bring up xfce4 as requested and can play music etc. However when I try to start client2 I get the menu which has 3 options. Suspend Terminate New If I select New then the X2GO screen briefly appears and then it returns to the menu. If I select terminate, it kills the session on client1 and then I can select New and client2 will display XFCE4. Is this expected behavior? All 3 are running freshly installed Arch linux. Thank you

Windows x2go client displays at incorrect resolution
by Davis, Jean-Paul 18 Apr '17

18 Apr '17

I'm hoping that someone out there with more experience will be able to solve this problem! Server = RHEL 7, running local GNOME-3 session at native 3840x2160 (dpi 149) of attached 4K display Installed Packages: x2goagent.x86_64 3.5.0.32-3.el7 @epel x2goclient.x86_64 4.1.0.0-1.el7 @epel-rhel-x86_64-workstation-7 x2goserver.x86_64 4.0.1.20-1.el7 @epel x2goserver-xsession.x86_64 4.0.1.20-1.el7 @epel Settings: /etc/x2go/x2go-agent.options - commented out X2GO_NXAGENT_DEFAULT_OPTIONS+=" -extension XFIXES" /etc/x2go/Xresources - set Xft.dpi: 192 Everything else left at defaults Client = Windows 10, x2go client v4.1.0.0, local native display 2560x1440 (dpi 192) Settings: Session Type = MATE (automatically changes to "Custom desktop" with command "MATE") Display = Fullscreen Set display DPI = 192 The session starts just fine, filling the screen with the MATE desktop, except that the display resolution is incorrect... with following information obtained inside a MATE terminal: jpdavis: xdpyinfo | grep dots resolution: 192x193 dots per inch jpdavis: ps -waux | grep $DISPLAY | grep x2goagent jpdavis 28204 0.2 0.3 217268 57696 ? S 10:05 0:08 /usr/lib64/nx/../x2go/bin/x2goagent -nolisten tcp -nolisten tcp -dpi 192 -D -auth /home/jpdavis/.Xauthority -name X2GO-jpdavis-50-1491062721_stDMATE_dp32 :50 jpdavis: xrandr --prop xrandr: Failed to get size of gamma for output default Screen 0: minimum 320 x 240, current 1280 x 720, maximum 1920 x 1200 default connected 1280x720+0+0 0mm x 0mm Thus the actual dpi being used by the display is 192*1280/2560 = 96, not the 192 sent to x2goagent and reported by xdpyinfo. attempting to change the resolution from inside the session... xrandr --size 1920x1200 works but keeps same actual dpi of 96 (so desktop is larger than my screen) MATE Settings->Hardware->Displays returns error "RANDR extension is too old (must be at least 1.3)" xrandr --version returns xrandr program version 1.4.3 Server reports RandR version 1.2 I get the same behavior if I try sessions with KDE or XFCE instead of MATE. Since the maximum resolution reported by xrandr corresponds to dpi of 192*1920/2560=144 x 192*1200/1440=160, I wondered if it had something to do with the local X session on the server which is at 149 dpi; closing that session, however, makes no difference. Could it be something about the X server that is running on the x2go server? (It is running but with no sessions, just the login greeter). The Windows client generates the following in the file .x2go\<session>\sessions: Loop: WARNING! Unrecognized session type 'unix-kde-depth_32'. Assuming agent session. Auth: WARNING! Failed to read data from the X auth command. Auth: WARNING! Generating a fake cookie for X authentication. Loop: WARNING! Could not retrieve the X server authentication cookie. Fork: WARNING! Function fork failed. Error is 11 'Resource temporarily unavailable'. Retrying... Fork: WARNING! Function fork failed. Error is 11 'Resource temporarily unavailable'. Retrying... Fork: WARNING! Function fork failed. Error is 11 'Resource temporarily unavailable'. Retrying... ... and the following in the file .x2go\<session>\options: nx/nx,root=/cygdrive/C/Users/jpdavis/X2GO~1,connect=localhost,cookie=6f9207806bc4e3206aa5df26759c77bc,port=60732,errors=/cygdrive/C/Users/jpdavis/X2GO~1/S-JPDA~1/sessions:50 Where could it be getting a session type of 'unix-kde-depth_32' when I've set it to use a MATE session? And where exactly do I find the /cygdrive/C/Users/jpdavis/X2GO~1 directory on my Windows machine? I can't find any files where x2go client saves program preferences or session preferences. Under the client settings, I changed to "use custom X server", pointed to the VcXsrv.exe file that comes with x2go, added "-dpi 192" to the command-line options for all cases, and restarted x2go. This had no effect. I also tried using the XMing X server with the same options, this also had no effect. More interesting information... If I simply Putty ssh to the server and run xrandr I get "Can't open display." If I enable X11 forwarding in Putty but don't start a local X server on the Windows machine, then xrandr returns slightly more information: "Can't open display 134.253.62.153:10.0." If I do this again but first start VcXsrv with the same command-line options as I've set in x2go ("C:\Program Files (x86)\x2goclient\VcXsrv\vcxsrv.exe" -fullscreen -notrayicon -clipboard -dpi 192) then xrandr returns "Screen 0: minimum 0 x 0, current 1280 x 720, maximum 4096 x 4096" (and xdpyinfo still says "192x193 dots per inch"). If I also add the command-line options "-screen 0 2056x1440", I get that resolution but much larger than my real display, and text is even larger. Finally, I tried using Putty X11 forwarding with XMing, with XMing options set via it's XLaunch executable. With XMing set to fullscreen and no additional options passed, xdpyinfo says "75x75 dots per inch" and xrandr returns "Screen 0: minimum 1280 x 720, current 1280 x 720, maximum 1280 x 72." Same result with XMing set to multiple windows. In this mode, graphical applications started from inside Putty actually don't look bad (normal text size). Adding command line option "-dpi 192" to XMing makes xdpyinfo return "192x193 dots per inch" but xrandr output remains the same, and the resulting graphical application text is way too large. Using XMing with Putty and X11 forwarding to start mate-session has the same issue, so I guess this is not actually an x2go problem. I'm still posting here in case someone can help, maybe I'll also look for user mail lists relevant to X in general, or VcXsrv/XMing. So what am I missing? Where is it getting the dpi=96 that the display is actually using? The 96 value makes the session fairly useless, as all display elements are huge compared to the screen. I had this working not that long ago, but I wouldn't be able to confirm exactly what changes have been made in the interim because I don't recall exactly _when_ it was working. Jean-Paul Davis

Running without window/desktop manager
by Marat Khalili 12 Apr '17

12 Apr '17

Dear all, I'm new to X2Go having used FreeNX previously. I've installed x2goserver on Ubuntu 16.04 server from ppa:x2go/stable, and can start published applications successfully. However, I didn't install any window or desktop manager, since I don't think my clients will need it. Neither did I install any bindings. I wonder, what features do I lose this way? Particularly, neither local printing nor shared folders seem to work (tested from Windows and Ubuntu 14.04 stock client), can this be related, or is it a separate problem? Directory ~/media/disk exists, but it is empty; and only "Print to File" is available in remote Firefox. If window/desktop manager is needed, which should I install to handle just this problem? Do I need bindings package too? (I'd prefer not to have unnecessary packages on my server to avoid frequent security updates.) -- -- With Best Regards, Marat Khalili

Sponsorship of X2Go macOS Client Development and of X2Go Linux on POWER Development
by Stefan Baur 07 Apr '17

07 Apr '17

Hi everyone, as previously announced, CFD.direct has decided to sponsor our macOS Client Development, and XCLOUD.me, has jumped right in and offered us a special rebate, so we can run two of their smallest instances for the price of one medium instance. This means that will be able to offer automated X2GoClient for macOS builds both for macOS 10.10 (these should work on 10.9 and 10.8 as well) as well as for macOS 10.12. The machines have been provisioned today, and Mihai will be setting them up over the course of the next few days. Once he's done with that, we'll move on to supporting the POWER platform directly again (at present, some distributions grab our source and turn it into packages for their POWER flavor, but there's no official X2Go repository where you could get stable or nightly builds directly from us). IBM and the Oregon State University's Open Source Lab have teamed up and are providing us with four POWER8 virtual machines (with the option to add more, should the need arise), manageable via an OpenStack WebGUI. Unlike the previous POWER8 virtual machine that we had, these new servers are going to be available for us for the foreseeable future. We intend to run at least two (one for Big-Endian, the other for Little-Endian) of those machines as Jenkins Build Slaves, just as the virtual macOS machines, so we will soon be able to provide automated builds for POWER. The other two we currently intend to run as demo servers and for testing and bugsquashing, though we might repurpose them as Jenkins Build Slaves if it turns out that we need one per Endianess *and* packaging system (DEB vs. RPM). There's one bug that's cropped up on POWER8 LE only, and we're already curious to learn what's causing it, so we're glad we finally have access to a test environment again. Here is a quick overview over the sponsors mentioned above: CFD Direct <https://cfd.direct> are the primary developers of OpenFOAM <https://openfoam.org>, the free, open source software for computational fluid dynamics. XCLOUD.me <https://xcloud.me/> is a hosting company that specializes in providing virtual macOS cloud instances - all 100% legal, as the virtual machines run on top of real Apple hardware. IBM are the original developers of the POWER systems used in midrange computing. You can learn more about the Linux on POWER ecosystem here: <http://www-03.ibm.com/systems/power/software/linux/> Oregon State University's Open Source Lab (OSU/OSL) is a nonprofit organization working for the advancement of open source technologies. They offer various means of support to open source projects, one of them being free hosting on both Intel and POWER servers. To find out more about them, please visit their web site at <http://osuosl.org/> Kind Regards, Stefan Baur X2Go Project/Community Manager -- BAUR-ITCS UG (haftungsbeschränkt) Geschäftsführer: Stefan Baur Eichenäckerweg 10, 89081 Ulm | Registergericht Ulm, HRB 724364 Fon/Fax 0731 40 34 66-36/-35 | USt-IdNr.: DE268653243
