Emacs crashes on start
by Roderick Johnstone 18 Sep '17

18 Sep '17

Hi I'm connecting from a Mac (X2Go Client v. 4.0.5.1 (Qt - 4.8.7)) to Fedora 24 with a xfce session using the x2goserver-4.0.1.19-11.fc24.x86_64 packages from the fedora repos. On starting emacs, I get the error below. This issue seems to have been around for a while in similar forms, but didn't affect me under Fedora 22. Is anyone in a position to confirm this issue on Fedora 24 and suggest a work around? I tried setting various environment variables suggested on various web pages for similar issues and in the bug report noted in the error message (and checked /etc/PROBLEMS), but nothing was effective. emacs starts fine in an xfce session at the console. Thanks Roderick Johnstone X protocol error: BadRequest (invalid request code or no such operation) on protocol request 131 When compiled with GTK, Emacs cannot recover from X disconnects. This is a GTK bug: https://bugzilla.gnome.org/show_bug.cgi?id=85715 For details, see etc/PROBLEMS.

Logging x2go connections?

Hi All, This perhaps is a trivial question: but is it possible to somehow log/check history of past x2go session on the server? -- Grigory Shamov Westgrid/ComputeCanada Site Lead University of Manitoba E2-588 EITC Building, (204) 474-9625

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

suppress GUI dialog when calling x2goclient --version from subshell
by Seth Galitzer 27 Mar '17

27 Mar '17

I'd like to be able to capture the version of x2goclient in a script and report it back to the user externally. Use case for this would be an external info dialog when running x2goclient in a thin client environment. Bash script would look something like this: #!/bin/bash VER=$(x2goclient --version) echo Your version is $VER The client generates lots of additional info and warning messages to stderr, which I can suppress using grep -v. I can get a clean version number if I call it standalone on the cli: $ x2goclient --version 2>&1 | grep -v x2go When I do this, however, I get "Terminated" added to the output. But as soon as I try to capture the output in a subshell per the first snippet, the client can't get the tty and so opens the GUI About dialog. I've tried using the --hide option, but this doesn't help. I would like to just be able to invoke the client and get just the version number with no additional output. I could just query the OS package manager to get the installed version, but this doesn't give an accurate result if I'm running from a binary I've compiled from source. I'm working on hacking the code to get the result I want, but wonder if there is an easier solution. Any suggestion? Please let me know. Thanks.

Frozen x2go session
by Thackeray, Neil L 27 Mar '17

27 Mar '17

I have a user with a frozen x2go session. In the logs I get the following message for the users session: usr/bin/x2gosetkeyboard: Waiting for /home/username/.x2go/C-username-50-1490056089_stDKDE_dp32/keyboard to appear. I'm thinking this might be the problem, but does anyone have any experience with this? I'm thinking I may have to terminate their session, which isn't great since they were crunching data for research. The server version is: x2goagent: 3.5.0.32 x2goserver: 4.0.1.20 x2goserver-extensions: 4.0.1.20 x2goserver-fmbindings: 4.0.1.20 x2goserver-printing: 4.0.1.20 x2goserver-xsession: 4.0.1.20 This is all running on RHEL 6.8. I don't know which client version the user has.
