Bug#1135: MySQL Database backend support
by Walid MOGHRABI 13 Jun '17

13 Jun '17

package: x2goserver priority: wishlist tags: patch This is a proposal patch for a MySQL session storage database backend for X2Go Server. I did this simply because : 1) I'm not used to PostgreSQL and much more skilled with MySQL 2) I do believe MySQL is pretty common on Linux and is widely spread so I guess this can be useful for many other people willing to build a strong TCE setup and not willing to dig into PostgreSQL 3) I find it a lot easier to build a multi-master replication scenario with MySQL than with PostgreSQL (but as I said, I'm much more skilled wih MySQL) This backend is tightly inspired by the PostgreSQL backend and work exactly the same so this is a drop in replacement for it, til now, all my tests seems to work correctly, feel free to test by yourself and report errors.

Bug#618: KDE panel and LXDE panel are hidden after login to x2go session
by Aki Ketolainen 29 May '17

29 May '17

Package: x2goagent Version: 2:3.5.0.27-0~446~ubuntu14.04.1 Package: x2goserver Version: 4.0.1.15-0~847~ubuntu14.04.1 Package: x2goserver-extensions Version: 4.0.1.15-0~847~ubuntu14.04.1 Package: x2goclient Version: 4.0.2.1+hotfix1+build4 Server = Ubuntu 14.04.1 LTS (x86) Client = Windows 8.1 (x86_64) After logging into x2go Server, I see either KDE or LXDE start up, as configured. Start up finishes but the panel in either KDE or LXDE is not shown. I press Alt+F2 to open the 'Run' application and start xterm. I run 'xrandr -s 1280x720', the x2go/X11 window size changes OK and the menu in either KDE or LXDE shows up automatically. I saw that someone had ran into this bug in 2012: http://readlist.com/lists/gentoo.org/gentoo-user/33/169010.html but there was just a temporary resolution to the problem.

Bug#1182: nxagent 3.6 and KDE4 causes X2Go Client for Windows's session window to "jump" up and down
by Mike DePaulo 29 May '17

29 May '17

Package: x2goclient Version: 4.1.0.0 Note: It is unclear whether this is a bug in nx-libs or x2goclient/VcXsrv Note: This bug does not occur with nxagent 3.5 (& x2goserver 4.0.1.20-1.el7 from EPEL) Note: This bug does not occur for Linux clients. Steps: 1. Start a KDE4 session in windowed mode. 2. Maximize the session. 3. Observe that the session window "jumps" up and down by tens of pixels. This happens repeatedly and very quickly. It has the appearance of it flickering almost. It makes it largely unusable. Note: This seems to go away on its own after seconds on my Windows 10 client, but it lasted indefinitely on my Windows 7 client. Server: CentOS 7.3 with KDE4 & x2goserver 4.1.0.0 nightly & nx-libs 3.5.99.7 (from copr repo mikedep333/nx-libs-3.6) Client 1: Windows 7 x64 SP1 with X2Go Client 4.1.0.0-2017.03.11 Client 2 Configuration 1: Windows 10 1703 x64 with X2Go Client 4.1.0.0-2017.03.11 (This has nx-libs 3.5.0.32) Client 2 Configuration 2: Windows 10 1703 x64 with X2Go Client 4.1.0.0-2017.03.11 & VcXsrv 1.19.2.0 (I replaced the VcXsrv subfolder) (This has nx-libs 3.5.0.32)

Heads-Up: X2Go: The Gathering 2017 will be taking place 2017-09-22 to 2017-09-24
by Stefan Baur 29 May '17

29 May '17

+++ Attention +++ Attention +++ Attention +++ Attention +++ X2Go: The Gathering 2017 will be taking place 2017-09-22 to 2017-09-24 We currently have two possible locations (Linuxhotel, and a hacker space in the southwest of Germany) that already confirmed they can host our event in the given timeframe, and are currently evaluating a third (in the city where X2Go was created, Treuchtlingen, Germany). A Wiki page with all available options will get linked and mentioned on the X2Go-Project Mailing List shortly after 2017-05-15 (our Decision Day for the Treuchtlingen location), along with a list of Pros and Cons for each location. We intend to have a public vote amongst all potential participants regarding the location from when said wiki page goes live until 2017-06-15. Note that we reserve the right to deviate from the poll result if it turns out that it would mean an undue hardship for one or more of the core X2Go team members or our sponsors, or if something happens after the end of the polling timeframe that requires us to reconsider, like, a location suddenly increasing prices, strikes, natural disasters, etc. Please mark the date in your calendars already, as while we haven't decided on the location yet, *the date is fixed* - as it is the only weekend where we have enough "critical mass" regarding the core X2Go team members.

Bug#1180: "Failed to restore all the required visuals" when switching from VcXsrv 1.19.2.0 to 1.17.0.0-3
by Mike DePaulo 28 May '17

28 May '17

Package: x2goclient Version: 4.1.0.0 Tags: +build-win32 When you do the following: 1. Replace x2goclient's VcXsrv folder with that upstream VcXsrv 1.19.2.0 2. Start an X2Go session 3. Suspend the session. 4. Replace x2goclient's VcXsrv folder with its default version, 1.17.0.0-3 (X2Go/Arctica builds) 5. Reconnect & resume the X2Go session You get the error message: Failed to restore all the required visuals And the session fails to resume. Yes, this is the same symptom as bug #891, but under different circumstances. https://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=891 I am sure it could be reproduced if you were to specify VcXsrv 1.19.2.0 as an external X server instead. Server: RHEL 7.3 with EPEL's x2goserver 4.0.1.20-1.el7 & nxagent 3.5.0.32-3.el7 & xfce 4.12.1 Client System: Windows 10 1703 x64

Bug#1181: Unable to logout of KDE4 when a PolicyKit prompt is up
by Mike DePaulo 27 May '17

27 May '17

Package: nx-libs Version: 3.5.0.32 Note: This bug might actually be in x2goserver instead. Steps: 1. You connect to a KDE4 server 2. You maximize the session 3. #2 This triggers a PolicyKit prompt "Authentication is required to create a color managed device" 4. You select to log out of KDE 5. The screen does not turn black. There is a log out dialog, but it is actually hidden behind the PolicyKit prompt. 6. You are unable to click the log out button in the log out dialog because it is not visible. Hitting escape does not help either. You are unable to move the PolicyKit prompt. Note: In the absence of the PolicyKit dialog, the screen still does not turn black. Note: #3. Is a nuisance in and of itself. It is related to the fact that PolicyKit applies different rules for physical logins (active) vs remote logins (inactive.) It is especially a nuisance because you have to click "cancel" repeatedly. However, it is not what I am reporting as a bug. If you have a local session, this bug does not occur: 3. Trigger a PolicyKit prompt by opening up a terminal and running `pkexec vi` for example. 5. The screen turns black, and the log out dialog appears. 6. You click the log out button and all is well. This can be worked around by moving the PolicyKit prompt before logging out, or by hitting "cancel" repeatedly. I am confident this can be worked around also by writing new PolicyKit rules that prevent the "color managed device" prompt. I will post how soon. However, other PolicyKit prompts can presumably still cause this issue. Server configuration 1: CentOS 7.3 with KDE4 & EPEL's x2goserver 4.0.1.20-1.el7 & nxagent 3.5.0.32-3.el7 Server configuration 2: CentOS 7.3 with KDE4 & nightly x2goserver 4.1.0.0 & nxagent 3.5.99.7 (from the copr repo mikedep333/nx-libs-3.6) Client 1: Fedora 25 x64 with Fedora's x2goclient 4.1.0.0-1.fc25 & nxproxy 3.5.0.32-4.fc24 Client 2: Windows 10 1703 x64 with X2Go Client 4.1.0.0-2017.03.11

However, from Session Preferences, I cannot select it. The similar options such as "fullscreen" and "maximum available" are not the same behavior. (For example, "maximum available" exhibits bug #618, and "fullscreen" exhibits bug #1178, but "Display 1" exhibits neither of those.) Note: This is a single monitor client.

Bug#1177: Sound does not work from EL6 clients with both pulse cookies
by Mike DePaulo 24 May '17

24 May '17

Package: x2goclient Version: 4.1.0.1 PulseAudio Sound fails to work when the following conditions are met: 1. The client is running RHEL 6/CentOS 6/etc 2. The client has both ~/.pulse-cookie ~/.config/pulse/cookie . For example, when the home directory is an NFS export mounted by both EL6 and EL7 systems. Running commands like `pactl list` on the X2Go server yields "Connection failure: Access denied". This is because the X2Go client system is using ~/.pulse-cookie with its PulseAudio server, but X2Go Client copied over ~/.config/pulse/cookie and is having the X2Go server system use it with its PulseAudio client libraries. This can be worked around by symlinking .pulse-cookie to .config/pulse/cookie .

Xinerama buggy?
by Ulrich Sibiller 15 May '17

15 May '17

Hi, in x2goclient's ONMainWindow::slotConfigXinerama you can find the following code that calculates the values for xinerama.conf. We see a race condition here where sometimes (well, quite often) this leads to negative x/y coordinates in xinerama.conf (size is ok) for new sessions when run from the thinclient setup. The code below contains annotations by me in [] with the variables' values that lead to the wrong xinerama.conf. I believe x2goclient sometimes catches the nxagent window too early before it is resized accordingly (maybe the window manager is too slow) thus getting a window of size 1x1 in the center of the screen (line 12): 1 void ONMainWindow::slotConfigXinerama() 2 { 3 QRect newGeometry=proxyWinGeometry(); [1x1@511,393] 4 if (newGeometry.isNull()) 5 { 6 x2goWarningf(7)<< tr("Error getting window geometry. (Did you close the window?)"); 7 xineramaTimer->stop(); 8 return; 9 } 10 if (newGeometry==lastDisplayGeometry) 11 return; 12 lastDisplayGeometry=newGeometry; [1x1@511,393] 13 QString geoStr = 14 "(x: " + QString("%1").arg(lastDisplayGeometry.x()) + 15 ", y: "+ QString("%1").arg(lastDisplayGeometry.y()) + 16 ", w: "+ QString("%1").arg(lastDisplayGeometry.width()) + 17 ", h: "+ QString("%1").arg(lastDisplayGeometry.height()); 18 x2goDebug<<"New proxy geometry: " + geoStr; 19 QDesktopWidget* root=QApplication::desktop(); 20 QList<QRect> newXineramaScreens; 21 for (int i=0; i< root->numScreens(); ++i) 22 { 23 QRect intersection; 24 if (resumingSession.fullscreen) 25 intersection=root->screenGeometry(i); [1024x768@0,0] 26 else 27 intersection=root->screenGeometry(i).intersected(lastDisplayGeometry); [ not executed ] 28 if (!intersection.isNull()) 29 { 30 // x2goDebug<<"intersected with "<<i<<": "<<intersection<<endl; 31 intersection.moveLeft(intersection.x()-lastDisplayGeometry.x()); [1024x768@-511,0] <- [0]-[511] 32 intersection.moveTop(intersection.y()-lastDisplayGeometry.y()); [1024x768@-511,-393] <- [0]-[393] 33 // x2goDebug<<"xinerama screen: "<<intersection<<endl; 34 newXineramaScreens<<intersection; 35 } 36 } 37 if (xineramaScreens != newXineramaScreens) 38 { 39 xineramaScreens=newXineramaScreens; 40 // x2goDebug<<"xinerama screen changed, new screens: "<<xineramaScreens<<endl; 41 xineramaTimer->stop(); 42 QStringList screens; 43 foreach (QRect disp, xineramaScreens) 44 screens<<QString::number(disp.x())+" "+QString::number(disp.y())+" "+QString::number(disp.width())+ 45 " "+QString::number(disp.height()); ["-511 -393 1024 768"] 46 QString cmd="export DISPLAY=:"+resumingSession.display+" ;printf %b '\\''"+screens.join("\\n")+"'\\'' > $HOME/.x2go/C-"+ 47 resumingSession.sessionId+"/xinerama.conf"; 48 sshConnection->executeCommand(cmd, this, SLOT(slotXineramaConfigured())); 49 } 50 } I am not really sure about the intentions behind this code. It looks to me that the if block (lines 28-35} should not run for the fullscreen case. Can anyone confirm this? Uli

i ran into this issue on ubuntu 16.04 (64 bit), and i can confirm that both workarounds (using Nouveau and setting LD_LIBRARY_PATH=/usr/lib/nvidia-375 ) fix the issue. to add a bit more info, it seems that in the failing case, glxinfo (or presumably the other apps), can't find the GLX_indirect library that it trys to load dynamically, which has something to glvnd: https://github.com/NVIDIA/libglvnd looking at ldd, you can see that glxinfo is finding the GL libraries fine, using the system-set ld.so.conf settings that the nvidia driver sets up: moskewcz@mari:/etc/ld.so.conf.d$ ldd /usr/bin/glxinfo linux-vdso.so.1 => (0x00007ffe4779c000) libGL.so.1 => /usr/lib/nvidia-375/libGL.so.1 (0x00007fcd87f35000) libX11.so.6 => /usr/lib/x86_64-linux-gnu/libX11.so.6 (0x00007fcd87bfb000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fcd87831000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007fcd8762d000) libGLX.so.0 => /usr/lib/nvidia-375/libGLX.so.0 (0x00007fcd873fd000) ... the paths are set here: moskewcz@mari:/etc/ld.so.conf.d$ cat /etc/ld.so.conf.d/x86_64-linux-gnu_EGL.conf /usr/lib/nvidia-375 /usr/lib32/nvidia-375 using strace, we can see the difference that setting LD_LIBRARY_PATH makes: # working case, opens the correct lib: moskewcz@mari:/etc/ld.so.conf.d$ LD_LIBRARY_PATH=/usr/lib/nvidia-375 strace glxinfo 2>&1 | grep GLX_ind open("/usr/lib/nvidia-375/tls/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) open("/usr/lib/nvidia-375/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = 4 # non-working case, fails to open libGLX_indirect.so: moskewcz@mari:/etc/ld.so.conf.d$ strace glxinfo 2>&1 | grep GLX_ind open("/lib/x86_64-linux-gnu/tls/x86_64/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) open("/lib/x86_64-linux-gnu/tls/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) open("/lib/x86_64-linux-gnu/x86_64/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) open("/lib/x86_64-linux-gnu/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) open("/usr/lib/x86_64-linux-gnu/tls/x86_64/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) open("/usr/lib/x86_64-linux-gnu/tls/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) open("/usr/lib/x86_64-linux-gnu/x86_64/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) open("/usr/lib/x86_64-linux-gnu/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) open("/lib/tls/x86_64/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) open("/lib/tls/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) open("/lib/x86_64/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) open("/lib/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) open("/usr/lib/tls/x86_64/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) open("/usr/lib/tls/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) open("/usr/lib/x86_64/libGLX_indirect.so.0", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) [...snip many more repeats of failed-to-load libGLX_indirect...] however, it's not clear why, under x2go, the nvidia code isn't searching in /usr/lib/nvidia-375 -- but it's not clear what code it uses for the DL loading, maybe it is somewhere in the glvnd code. mwm

> It is not "unusable". But nx offers an old version of GLX only. And > there seem to be some applications that don't care for the version the > X server (nxagent in this case) reports. So what should we do? You're right, I'm probably a bit to0 rude with this but it's far too old and most applications just test if GLX is enabled without testing it's version or correct support for each extensions which leads to crashes at times. Since there is no gain in keeping it "as is" (at least, I did see more problems than gains) and until GLX support is updated through Lib-NX, I personnaly would recommend disabling GLX by default (which let the possibility to the user to activate it if he really needs it but don't make this the default behaviour). Since applications are checking if GLX is enabled, disabling it force them to fallback on software renderers only (or don't run at all but I prefer that to crashes for unknown reasons). > It is possible to implement a newer GLX version but that would need > some investing quite some time. Unfortunately the current nx > development staff does not have that time... I know and I upvote for that as top priority since more and more applications needs this.

Bug#1172: ThunderBird crashes in PubApp mode on amd64
by Stefan Baur 09 May '17

09 May '17

package: nx-libs Hi, since Debian Jessie (stable) switched from IceDove back to ThunderBird, TB crashes when the host is an amd64 machine and X2GoClient is running in PubApp mode. i386 is unaffected. It happens with X2GoClient on Windows as well as on Linux, so it's not a matter of VcXsrv being too old/broken/whatever. It also happens when all X2Go server components are installed from heuler. It does NOT happen when you build nx-libs from source using the Debian Experimental repository. So there's something in the stable nx-libs that's broken on amd64 only, and got fixed in the nx-libs version that is available via Debian Experimental. Core-Devs, please advise how to fix this - should we dare making a new nx-libs release and declare it stable, based on what is in Debian Experimental (arguing that everything is better than what we currently have)? Or should we try to hunt down the offending code part and only patch that? If the latter, who's willing to take a stab at it? (We don't have a business case ATM, as all my TB-PubApp-users are still on i386, so no funding as of now.)

Bug#1174: file is blocked (stDXFCE_dp24)
by Felix B. Müller 05 May '17

05 May '17

Package: x2go-server Version: 4.0.1.20 Dear all, I have an Ubuntu 16.04.2 LTS (Server) which is integrated in the Windows Active Directory (AD). The user authentification is done via Kerberos followed here: https://help.ubuntu.com/community/ActiveDirectoryWinbindHowto The directories are also mounted automatically every time the user logs on via pam_mount: <volume user="*" fstype="cifs" server="fileserver1" path="home/%(DOMAIN_USER)" mountpoint="/home/%(DOMAIN_USER)"/> This works quite nice and I can login via ssh with the user names of the AD. I also would like to use x2go for the AD users. However, it works fine when I try to connect to the server (called ssh or ssh2) from the internal network (192.168.0.0). The users get their remote desktops. However, if they try to login remotely from another subnet the session could not be initialized. I was looking for the problem the last 3 weeks. Of course the first idea was due to a misconfigured firewall. The configuration is as follows: INTERNET ----- NAT1 -----(192.168.183.0)------ NAT2 ----(192.168.0.0)------ ssh-server I replaced the firewall, I put the PC (ssh-server) directly after the NAT. I had a look in all network connections with wireshark. I opened all ports. None of these things solved the problem. However, I can login with a local user (user account on the ssh-server) on the ssh-server but not with a user of the AD (username test01). I set the logging to the debug mode and I see that a file is always blocked. I do not understand why this file is blocked if I login from another subnet. Maybe this is not a bug I do not know and I do not understand this behavior.

x2goclient crashes gnome-session
by Live System User 28 Apr '17

28 Apr '17

Hi, It appears that invoking x2goclient crashes my gnome-session on Fedora 24 with my custom setup (gnome-session-test). After the black x2go box comes up, it quickly disappears along with the gnome-session that was there before I invoked x2go client. The only thing left on the screen is the wallpaper. I can't bring up a gnome-terminal from the "Activities" menu (the cursor spins for a moment and then nothing happens). The only thing I can do is to logout. Here is some info from /var/log/messages. Let me know if (and how to obtain) any additional info that I need to provide. Thanks.

Bug#1164: proposed patch for 2800-x2go-thinclientconfig in live-build-x2go overlay to handle custom image urls passed in as kernel boot options
by Seth Galitzer 25 Apr '17

25 Apr '17

Package: live-build-x2go, feature/openbox branch Version: git commit e4cfc12441e587d89d0b2b90021ee5fb5799a46f Tag: patch The attached patch updates the 2800-x2go-thinclientconfig hook file in the overlay tree from the feature/openbox branch of live-build-x2go used to build live boot images for the Thin Client Environment for X2Goclient. Full path in the tree is [live-build-x2go.git]/config/includes.chroot/lib/live/config/2800-x2go-thinclientconfig. It provides two things: 1) handle backgroundurl option as passed in as a kernel boot option and used by --background flag when invoking x2goclient on the commandline 2) handle brandingurl option as passed in as a kernel boot option and used by --branding flag when invoking x2goclient on the commandline per patch provided in bug #1162 This patch was built and tested against the most recent commit to the branch with id e4cfc12441e587d89d0b2b90021ee5fb5799a46f and timestamped Sun, 29 Jan 2017 13:53:42 +0000 (14:53 +0100).

Bug#1168: x2go slowdown after a few hours of using Cadence

Package: x2goserver Version: 4.0.1.20 The client machine's OS: Windows 10 The client machine's version of X2GoClient: 4.1.0.0-2017.03.11 Any relevant session settings in X2GoClient: XFCE or KDE session The server's OS: Centos (3.10.0-514.el7.x86_64) 7 The server's version of the x2goserver package: 4.0.1.20 After a few hours of running a certain tool (Cadence - unfortunately not open source), we see a sudden slowdown where the whole session reacts very very slowly and screen refreshes also very slowly. The load on the server is not significant and the server also has plenty of memory. Sometimes, if we leave it alone for a few minutes, it can recover, but not always. If we open another session in parallel, that new session is fine. --Kartik Movandi Corporation CONFIDENTIALITY NOTICE: This email may contain confidential and/or privileged information for the sole use of the intended recipient.

Sponsorship of X2Go macOS Client Development and of X2Go Linux on POWER Development
by Stefan Baur 09 Apr '17

09 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

X2Go client to search for server?
by John Cobo 01 Apr '17

01 Apr '17

Hello, I am considering X2Go for a project which involves non-technical people using X2Go to connect to a Raspberry Pi which does not have a screen and so the user will not know the Pi's IP address. I could set an SSH port on the Pi to an obscure number such as 2432 or something. Would it be feasible for the X2Go clients have a new option to scan a range of IPs (eg. 192.168.0.1 - 192.168.0.255) for a given port (eg. 2432) on which to connect? Such a feature could solve the generic problem of how to connect for the first time to something new on your local network. Thank you, John Cobo

Bug#1109: Print all In new window Long delays (i.e. several minutes) waiting for redraw ONLY in seamless window mode
by Aki Ketolainen 31 Mar '17

31 Mar '17

Hi, I noticed yesterday that disabling "show window contents while moving" in Mate desktop and XFCE fix this behaviour. I haven't found the setting to do this in Unity, though. Also KDE, LXDE and Windows on the client side don't show this behaviour. @sunweaver on #x2go on freenode commented that "21:55 <@sunweaver> I guess a sustainabe fix is grabbing the window content client side and keep that static pixmap until movement is over." Best regards, Aki
