Upcoming Deprecation of (Almost) EOL Distributions
by Mihai Moldovan 07 Feb '18

07 Feb '18

Hi In order to lower resource stress when building packages, I plan to deprecate support for distributions that have (almost) reached End Of Life on December 31th 2017. This includes the following distro versions: - Debian: o 7.0 "wheezy" - Fedora o 23 o 24 o 25 - OpenSuSE o 13.1 o 13.2 o 42.1 Ubuntu builds are ceased automatically after upstream deprecation. After deprecation, no new builds will be published and existing builds will be moved to the archive repositories to discourage users from installing unmaintained software. Mihai

Bug#1213: Missing icons in Eclipse toolbars with GTK2 in Published Apps mode
by Walid MOGHRABI 18 Dec '17

18 Dec '17

Package: x2goserver Version: 4.1.0.0-0~1413~ubuntu16.04.1 Running Eclipse with GTK2 backend in Published Apps mode leads to missing icons in the toolbars. They refreshed once you pass the mouse over or switch from one perspective to another so it's not too annoying but that's not great. This doesn't happens with GTK3.

Bug#1237: libssh issue
by Orion Poplawski 30 Nov '17

30 Nov '17

Looks like it is a libssh issue. I built 0.7.5 locally and the crash went away. I've filed https://bugzilla.redhat.com/show_bug.cgi?id=1519400 upstream to try to get libssh updated. -- Orion Poplawski Manager of NWRA Technical Systems 720-772-5637 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion(a)nwra.com Boulder, CO 80301 https://www.nwra.com/

Bug#1237: x2goclient segfaults on EL7 with libssh 0.7.1
by Orion Poplawski 30 Nov '17

30 Nov '17

Package: x2goclient Version: 4.1.1.0 Testing 4.1.1.0 on EPEL7 with libssh-0.7.1-3.el7. I'm getting segfaults trying to connect to the server. valgrind is reporting some invalid reads and writes. I suspect that something is wrong with the threaded version. I've attached the valgrind output with SSH_DEBUG defined. -- Orion Poplawski Manager of NWRA Technical Systems 720-772-5637 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion(a)nwra.com Boulder, CO 80301 https://www.nwra.com/

X2Go on a Mac using nightly builds to Fedora 26 keystroke problem, LibreOffice menu fonts squished and loss of focus
by Robert Kudyba 29 Nov '17

29 Nov '17

We have a Mac High Sierra user on the nightly builds connecting to a Fedora 26 workstation also on nightly builds with x2goserver-4.1.0.0-0.0x2go1.0.git20171111.1441.heuler.fc26.x86_64 Using MATE, keystrokes don't echo properly. If he types "ls" into a Terminal window, a "k" appears. XFCE works fairly well. The main complaint is that menus on LibreOffice are all squashed together. Screenshot at https://drive.google.com/open?id=1H7RPVP0qxqB_37Slbba8rlqdcITaEiDN Also, he stills getting "loss of focus". At more-or-less random times, the window in which he's typing quits reacting to his keystrokes. Clicking into the window resumes the focus. This is the same user that had the mixed nx-ibs packages issue.

Problem connecting
by Paul Borowicz 27 Nov '17

27 Nov '17

I've always had no problems connecting to x2go with only port 22 open on my router. Just recently I've been unable to connect. I turned on debugging and see my client connecting in the system logs: client X.X.X.X has successfully resumed session with ID paul-50-1511705558_stDXFCE_dp32 However, on the client I get an error that says "could not establish connection to remote proxy" I see this error repeating when I run the client with a --debug flag: 2go-DEBUG-../src/onmainwindow.cpp:10759> "Searching proxy window: X2GO-paul-50-1511705558_stDXFCE_dp32" x2go-DEBUG-../src/onmainwindow.cpp:12465> "Searching window with title: X2GO-paul-50-1511705558_stDXFCE_dp32" I'm not using a proxy for the internet.

Bug#1234: acl-users-allow=ALL superceeds acl-users-deny
by Walid MOGHRABI 26 Nov '17

26 Nov '17

package: x2gobroker priority: normal tags: patch When using ACLs with the session broker, I wanted to give access to a session setting to ALL users EXCEPT some (namely "formation{1..9}"). I tried this but it didn't work : ================================================= [TRAVAUX] fullscreen=true clipboard=none name=TRAVAUX host=tce-server (10.10.10.1) acl-users-allow=ALL acl-users-deny=formation1, formation2, formation3, formation4, formation5, formation6, formation7, formation8, formation9 acl-any-order=deny-allow ================================================= I played with many settings, changing order, using only the "acl-users-deny" option, ... none of them worked as expected. I ended in thinking that there was a bug with acl-users-allow=ALL which was taking over any other setting. I did a little fix that seem to work, at least for this use case.
