Re: [X2Go-User] libclutter problems (evolution, gnome-nibbles, cheese, ...)
As far as we know, support for GLX 1.4 (rather than GLX 1.2) and support for RandR 1.4 (rather than RandR 1.2)[1] in nx-libs 3.6.x will fix kde5. Hopefully kde5 doesn't require the composite extension also like GNOME3 does. I am not sure if the composite extension will be supported in nx-libs 3.6.x, or 3.7.x. -Mike [1] https://github.com/ArcticaProject/nx-libs/issues/48 On Wed, Jun 3, 2015 at 1:15 AM, Robert Dinse nan...@eskimo.com wrote: I understand there is no ETA, but will this also fix kde5?

If you are using the latest version (4.0.3.1-20141214), you can use a debug build. If you can copy the entire command-line output from the debug build, great. (A command-line window opens when you launch the debug build.) Otherwise, at least tell us the last few/several lines before it fails to connect.

Then Save Private Key. Then when you launch PuTTY: specify the hostname/IP Specify the port (if you never changed the port, 22 is the default). Then: Connection - SSH - Auth - specify the Private key file for authentication Go back to Session. For convenience, give the session a name and click Save. Now click Open (to connect.)

I've done this for ssh agents between linux machines, using ssh-keygen to obtain the keys. Not clear how to do so w/X2GO client running under Windows. Can you provide some instructions? If you have access to a Linux machine, just run ssh-keygen there with the usual parameters, copy the private key file over to the Windows machine, and specify it in the session settings (there's a field where you can specify the path to an RSA/DSA key). On the Linux box, add the public key to the authorized_keys file of the user account you're trying to log in as, and you should be all set. If you want to create your key pair on Windows, you will need to use either ssh-keygen from a cygwin install, or PuttyGen.exe from the PuTTY tool suite - for the latter, you will need to use the export function of PuttyGen's GUI to save the private key, as PuTTY's own *.ppk key storage files are incompatible with standard ssh.

Re: [X2Go-User] Changing the X2Go Client for Windows version numbering
Hi James, Thanks for your feedback. 1st, I should have discussed this earlier. If there was more discussion time, I might have gone with version numbering like 4.0.3.0.0, 4.0.3.0.1 and 4.0.3.0.2 for all Windows hotfixes/builds for 4.0.3.0. I've only ever released 1 hotfix. It was released because there was 1 single commit from the next version that needed to be included, and it was Windows specific. IIRC, it would have been too much work to release a new version for all platforms. Usually a new version, even if it is a 4th digit update, has dozens of commits. I will proceed with using the date for 4.0.3.0. I will release 4.0.3.0-20141021. As you point out, consistency is important. -Mike#2 On Mon, Oct 20, 2014 at 8:27 AM, James M. Pulver jmp...@cornell.edu wrote: Personally, I don't love either build numbering method. That said, I find the date suffix much harder to parse personally, it's too many numbers munged together and I just end up ignoring it. What do you all mean by the numbering anyway - i.e. why would 4.0.3.0+hotfix1 Not be 4.0.3.1? Personally, from a Windows admin / user perspective, I don't care what the build process is in terms of a binary I download. I care if something changed. So if 4.0.3.0+build1 changed the version of gcc but didn't change the output, I doubt anyone would care - maybe somewhere would be a build # for deep debugging, but it wouldn't be in any download name someone would use. If 4.0.3.0+build2 packaged a new library that fixed a bug, I'd expect to see 4.0.3.1 again as it fixed something in the product from my perspective. I'm a fan of MajorChange.MinorFeatureChange.Bugfix.someotherchange sort of software numbering. That all said - I would like to see the numbering be consistent across platforms in terms of code that is shared, and the method also be consistent. -- James Pulver CLASSE Computer Group Cornell University -Original Message- From: x2go-user-boun...@lists.x2go.org [mailto:x2go-user-boun...@lists.x2go.org] On Behalf Of Michael DePaulo Sent: Monday, October 20, 2014 8:16 AM To: x2go-user@lists.x2go.org Subject: [X2Go-User] Changing the X2Go Client for Windows version numbering X2Go Users, I'd like feedback on this topic. I am thinking of switching the X2Go Client for Windows version numbering over to the version numbering that X2Go Client for Mac OS X uses such as: If X2Go Client for Windows 4.0.3.0 were released today: 4.0.3.0-20141020 If I had to make any sort of change, either in the build process or in the source code, on 2014-11-21: 4.0.3.0-20141121 The reason for this change is that I believe these version numbers will be simpler and less confusing. This would be especially true for Windows users who are not used to the version numbering used by Linux distros. Under the current version numbering , if I were to build X2Go Client for Windows 4.0.3.0 when it is released the version number would simply be: 4.0.3.0 Then say I had to make 2 changes to the build process, such as calling different commands during the build process or bundling different 3rd party binaries/libraries (e.g., VcXsrv, OpenSSL). The 2 new version numbers would be: 4.0.3.0+build1 4.0.3.0+build2 If I had to then make a change to the source code, it would be: 4.0.3.0+hotfix1 And if I had to make 2 more changes to the build process, the 2 new version numbers would be: 4.0.3.0+hotfix1+build1 4.0.3.0+hotfix1+build2 -Mike#2 ___ x2go-user mailing list x2go-user@lists.x2go.org http://lists.x2go.org/listinfo/x2go-user ___ x2go-user mailing list x2go-user@lists.x2go.org http://lists.x2go.org/listinfo/x2go-user ___ x2go-user mailing list x2go-user@lists.x2go.org http://lists.x2go.org/listinfo/x2go-user

On CentOS7, it is called x2gocleansessions and is a systemd service. On Ubuntu 14.04, it is called x2goserver and is an init script. That said, I think I see a bug on CentOS 7: x2gocleansessions. does not seem to be enabled. I will look into this. I am using x2goserver 4.0.1.15 from EPEL.

Do you know any difference or limitation between Ubuntu 14.04 and CentOS 7 from X2Go POV? Gabor Hi Gabor, (I will refer to CentOS 7, RHEL 7, Oracle Linux 7, etc as EL 7.) 1. It appears that you can workaround the aforementioned issue with this command: sudo systemctl enable x2gocleansessions.service Based on my initial research [1][2], this might not be a workaround but instead a necessary step for installing X2Go from EPEL or from Fedora/EL RPMs in general. I need to do more research though 2. There might be bugs in x2goserver-xsession in terms of how we handle launching X11 sessions. The Xsession scripts provided by Debian/Ubuntu are very different from those provided by Fedora/EL. I do believe that Mike#1 fixed many of these bugs recently though as part of a contract for improving our EL packages. 3. If you wish to install the X2Go Session Broker, it is not available in EPEL. But it is available in our nightly builds for EL 7: http://wiki.x2go.org/doku.php/wiki:development:nightly-builds?s[]=nightly 4.

If you are still having trouble running it, let me know and I'll test gazebo on a KVM/virt-manager Ubuntu 12.04 VM at my home. I will send you in private a virt machine to test. Good news and bad news. :-) Bad News: It looks like nxagent (and therefore X2Go) is too old to run OGRE apps linked against Ubuntu 12.04's libraries. Maybe it could be recompiled against older x server libs and run, but I don't have time to try that . I also was unable to run it under cygwin X11 for some reason. Ok, so as you said, the problem is the nxagent is too old. Good News: I was able to run Gazebo and the OGRE's SampleBrowser under KVM virt-manager using SPICE and QXL. I am not sure if my host system was providing the new (experimantal) virtio-gpu or not. The OGRE SampleBrowser ran surprisingly well. so, may I understand that you connect remotely to the host and run virt- manager and then visualize the box? The architecture you have right now is this: 1. Your host has qemu-kvm hosting the VM. 2. The host has libvirtd managing qemu-kvm. 3. virt-manager can be opened and closed on the server, locally or over x2go, to manage the libvirtd. Your client should run virt-viewer instead of x2go client. virt-viewer is available for both Windows and Linux. virt-viewer (a Red Hat sponsored project) is available not only for Red Hat based distros, but also for Ubuntu, Debian and other distros. The URL to enter in virt-viewer is spice://hostname:59xx, where hostname is the host, and 59xx is the port that virt-manager lists for the display. When you select the display under the VM's hardware details, it should list what port it is on. If the port is not listed, remove and add the display, and configure the display to listen on All interfaces. You could also run virt-manager directly on the client and connect to the server's libvirtd with it. virt-manager is available for Linux, but not for Windows. You do not need libvirtd running on the client, although the OS may make the virt-manager package depend on the libvirtd package. If so, just disable the libvirtd service from running. I successfully did this on both your VM and a VM i created with the original 12.04 HWE stack. On your VM, i first ran this command to make sure that the 13.10 HWE X server and X libraries are installed. You have a bunch of 12.04 HWE X libraries installed, but they are not supported with the 13.10 kernel that you have (kernel 3.11). sudo apt-get install --install-recommends linux-generic-lts-saucy xserver-xorg-lts-saucy libgl1-mesa-glx-lts-saucy Ok To run the OGRE SampleBrowser, I ran this package installation command: sudo apt-get install ogre-samples ogre-tools ogre-doc Then just run: SampleBrowser Screenshots (from my VM, but your's worked too): http://imgur.com/a/zwPz9 Done, worked with virt-manager but not connecting with x2goclient.

The client really ought to show these kinds of errors without you having to kill the process on the server. But there is a bug in the Mac client where you cannot check the show details button until *after* a successful login. Therefore you never get to see the verbose output when your logins fail -- which is when it would be most useful to see it! Is there an existing bug report for this behavior of the Mac client? If not, please report it. Instructions: http://wiki.x2go.org/doku.php/wiki:bugs Anyway after some digging on that error message, I figured out that my problem was that my Bitnami AMI had me signing in as username ubuntu which is really just an alias to the user bitnami. But because I was signed in as a different username than the name of the home folder, it was messing up. When I logged instead using bitnami as the username, then suddenly it worked... kind of. OK. I think I this should be documented on the wiki as under a page like known issues with virtual appliances. Or common configuration issues. I'll take care of that. I want to see if there is an existing page 1st. Thank you for documenting it via this email. gnome-session --session=gnome-fallback does not work for me... I'd see the screen but was not able to click on anything. I thought, maybe I have the wrong bindings installed, so I tried to aptitude install x2gognomebindings but it just kept saying this error: Couldn't find any package matching x2gognomebindings. However, the following packages contain x2gognomebindings in their description: x2goserver-fmbindings So then I installed the x2goserver-fmbindings and I still couldn't get it to respond. I could see the desktop but nothing happens if I click. I could also not get on with just using the GNOME selection. See comment below about UNITY. I did have better luck with gnome-session --session=gnome-classic but it's still unusably slow. Even on 32k JPEG and with bandwidth set to WAN, stuff just happens way too slow, or doesn't happen at all. I know it's not my connection that's the problem. It's probably because it's an Amazon Micro instance, and it's just dog slow. If I use xfce4, I wonder if it would run faster? I'd like to try your xfce4 steps but I've already installed ubuntu-desktop, so will it hurt me to also install xfce4 alongside it? Can I have both installed? I just want to know if I should start over fresh with a new AMI. I don't need anything fancy, just want a GUI for managing files and running basic utilities like a git client. OK, I think I see the problem. ubuntu-desktop. You have the UNITY desktop environment installed, not vanilla GNOME. Please try specifying UNITY as your session type. Our logic in the x2goserver package will make sure Unity runs in Unity 2d mode. This mode is provided by package unity-2d. ubuntu-desktop depends on unity-2d, so you do have unity-2d installed. Also, as for XFCE: It's lightweight and it never tries to use 3d effects, so it runs faster to one degree or another. I recommend installing it according to my instructions. Absolutely, you can have both desktop environments installed. If you had a physical machine, you would select which desktop environment to use at the display manager's greeter (the graphical login screen.)

Re: [X2Go-User] X2Go Windows Client on Windows 8
Hi James, Can you confirm that you get no further details when you attempt to launch VcXsrv from the command-line? Here's an example of an error I get when launching it from the command line. (In this case, the workaround would be to add specify display :2 because I already have X2Go's VcXsrv instances running on :0 and :1). http://imgur.com/YjPJuJy -Mike#2 On Tue, Jun 10, 2014 at 2:07 PM, James M.

Re: [X2Go-User] X2Go Windows Client on Windows 8
3.x used Xming (XMing Public Domain Release) instead of VcXsrv. Please help us debug this by doing what you said. In the meantime though, you might want to try specifying Cygwin X11 or Xming (Xming Public Domain Release) as the external X server. You specify an external X server under: Options - Settings - X-Server settings. Note this bug though. At least you can workaround the bug: http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=109 If you need help figuring out the arguments to pass to Cygwin X11 or Xming, I can probably help you later today or tomorrow. -Mike#2 On Wed, Jun 11, 2014 at 8:41 AM, James M.

Re: [X2Go-User] ubuntu 14.04 desktop black screen on connect

I choose gnome as session and when I try to connect I obtain a black screen. Help me please!! :-) Thanks Cristina Hi Cristina, Sorry that you are running into the issue. 1st of all, because you are on Ubuntu 14.04, it would be easiest if you would use a desktop environment other than GNOME3 or UNITY. KDE, XFCE and LXDE are included in Ubuntu 14.04 and work fine with X2Go. You can also install MATE (the fork of GNOME2) from http://mate-desktop.org/ . There are other desktop environments that I haven't listed. However, it is possible to make GNOME3 work on Ubuntu 14.04. GNOME3 will use gnome-panel, not gnome-shell. There will also be bugs. For example, the desktop wallpaper does not show up The email is not showing up on lists.x2go.org or gmane.org, but Eugene San sent the email forwarded below with the currently available fix for GNOME3. His email is written from a developer's perspective. So below are user instructions I just wrote that you can follow. 1. Add this PPA: https://launchpad.net/~eugenesan/+archive/ppa?field.series_filter=trusty 2. Install all available updates from the PPA (if need be, I can narrow down which exact packages you need to update.) 3. Install the following packages: gnome-panel gnome-applets gnome-session-flashback 4. create the file /usr/local/bin/gnome-flashback.sh with the following contents: gnome-session --session=gnome-flashback 5. Make that file executable 6. In X2Go Client's session preferences, specify a custom desktop with the following command: gnome-flashback.sh Steps 1-2 are due to a bug in Ubuntu that we hope to fix soon. (The bug is that gnome-session checks for 3D acceleration, even though gnome-flashback doesn't require it.) Step 3 will be required until we develop an easier solution for installing those packages. We are thinking of creating a metapackage that depends on them. Steps 4-6 are due to a bug in x2goserver that has already been fixed in our git repo. When x2goserver 4.0.1.16 is released, it will contain the fix, and you will merely need to select GNOME as the session type in X2Go Client instead. -Mike -- Forwarded message -- From: Eugene San eugene...@gmail.com Date: Sun, Apr 20, 2014 at 7:52 AM Subject: Re: [X2Go-Dev] FYI: I am working on x2go GNOME3 compatibility in Ubuntu 14.04 To: Michael DePaulo mikedep...@gmail.com Cc: x2go-...@lists.x2go.org Hi all, Reading Michael's message and Andrew's article (http://www.webupd8.org/2014/04/how-to-install-and-tweak-gnome.html) inspired me to attempt to revive gnome-fallback (flashback) using x2go on Ubuntu14.04.

Install gnome-applets-window and add it's applet to panel. 2. Install metacity and disable window decoration in full screen by invoking: gsettings set org.gnome.metacity show-maximized-titlebars false Note, there are some minor visual glitches, at which I might look later.
