Bug#374: Setting keyboard layout in x2gothinclient
by Anders Bruun Olsen 29 Aug '14

29 Aug '14

Package: x2gothinclientmanagement Version: 1.1.0.1 Severity: wishlist After running x2gothinclient_create, the created chroot environment will default to US keyboard layout. This can be fixed by changing /opt/x2gothinclient/chroot/etc/default/keyboard, but it would be nice to have this as an option in /etc/x2go/x2gothinclient_settings, that would be read and effectuated by x2gothinclient_create and x2gothinclient_update. -- Anders Bruun Olsen It-ansvarlig Det Danske Sprog- og Litteraturselskab (Society for Danish Language and Literature)

Bug#457: Fwd: polkit-gnome-authentication-agent-1 fails to start on specific distros
by Michael DePaulo 23 Aug '14

23 Aug '14

Package: x2goserver Version: 4.0.1.13 Notes: 1. I am not sure if this is a bug in x2goserver, x2goserver-xsession, or in nx-libs. 2. This bug is probably in X2Go's integration with ConsoleKit (or lack thereof.) PolicyKit depends on ConsoleKit (and on systemd-logind in newer distros.) 3. RHEL7 beta (systemd-logind) is not affected and pkexec commands do work. However, PolicyKit authentication within apps fails. I will file a separate bug about this. 4. I also tested Ubuntu 12.04.4 LTS 32-bit (ConsoleKit) with Unity and with MATE 1.6. On that distro, polkit-gnome-authentication-agent-1 (Unity) & polkit-mate-authentication-agent-1 do start, but pkexec commands fail for another reason (the app complains that it cannot open the display.) A simple workaround for this case is to export XAUTHORITY 1st, I will file a separate bug about this. 5. polkit-gnome-authentication-agent-1 is started as gdm, but it should be started as the user also. Test system: CentOS 6.5 64-bit x2goserver: 4.0.1.13 x2goserver-xsession: 4.0.1.13 (same behavior when this package is not installed) nx-libs: 3.5.0.22 GNOME (This distro uses ConsoleKit, not systemd-logind) [batmin@mothership-el6 ~]$ pkexec gpk-application Error executing command as another user: No authentication agent was found.

Bug#459: PolicyKit authentication within apps often fails
by Michael DePaulo 22 Aug '14

22 Aug '14

Package: x2goserver Version: 4.0.1.13 Notes: 1. I am not sure if this is a bug in x2goserver, x2goserver-xsession, or in nx-libs. 2. PolicyKit depends on ConsoleKit (and on systemd-logind in newer distros.) 3. The behavior seems to be distro-specific and/or app-specific. 4. This bug report differs from 458 because PolicyKit authentication is being called within an app, not when launching the app. This is part of the PolilcyKit architecture: The apps run unprivileged and rely on PolicyKit in order to speak to privileged processes that do the actual task. For example, in test case 2, gpk-application is launched unprivileged. It uses PolicyKit to speak to the PackageKit backend, and the PackageKit backend does the package install. Test system: Fedora 20 64-bit MATE Desktop 1.6.2.1.fc20 - used for all 3 test cases x2goserver 4.0.1.13.2.fc20 x2goserver-xsession 4.0.1.13.2.fc20 nxlibs 3.5.0.22.1-fc20 (This distro uses logind) (/usr/libexec/polkit-mate-authentication-agent-1 is launched automatically when I login over X2Go. This distro is not affected by bug 457) Test Case 1: Steps: 1. Launch yumex (from start menu or from console) 2. Switch to the yumex's "history" tab on the left.. Expected result: A policykit authentication window opens up, I select a user to authenticate as (myself or root), enter my password, and then the history is populated within yumex. Here is an image of that policykit authentication window: http://imgur.com/JUZTBHo Actual result: The authentication window does not open up and the history is no populated. Instead, I get an error message windows. When I click "Close" on the window, yumex closes. Error message: Fatal Error: polkit-not-authorized Could not get polkit autherisation to start backend Yum Extender will terminate Here's an image of the error message window http://imgur.com/ABYETM0 >From the command-line, I can see this output when I select the history tab: 15:53:07 : INFO - YUM: Error executing command as another user: Not authorized 15:53:14 : INFO - yum backend process is ended 15:53:14 : INFO - yum backend process is ended Test Case 2: Steps: 1. Launch gpk-application (GNOME "Software Install" AKA "Add/Remove Software") 2. Select to install a single package. 3. Click "Apply Changes" Expected result: A policykit authentication window opens up, I select a user to authenticate as (myself or root), enter my password, and then the package is downloaded & installed (over the course of at least a few seconds), during which a progress bar is displayed. Screenshot: http://imgur.com/lLNof08 Actual result: The authentication window does not open up. The progress bar for the install completes in about 1 second. The package is not installed. (Interestingly enough, the package is still selected to be installed, but the "Apply Changes" and "cancel" button are hidden. This is a bug in gpk-application, it does not know how to handle policykit having an error. But this gpk-application bug is besides the point.) Screenshot: http://i.imgur.com/28lCZF5.png Also, the command-line does not show any relevant output. Test Case 3: Steps: 1. Launch virt-manager (AKA "Virtual Machine Manager") This test case actually passes! Expected & Actual result: A policykit authentication window opens up, I select a user to authenticate as (e.g., myself or root), enter my password, and then I am connected to the local libvirtd instance and see the VMs running. Screenshot: http://imgur.com/mZSgdMW Also, the command-line output does not include any details about PolicyKit (succeeding.) Note: Test case 3 fails on CentOS 6.5 64-bit. However, CentOS 6.5 64-bit is affected by bug 457, so that precludes running this test case.

Bug#262: Color issue with some programs GUI when used with X2GO (ok with NX)
by Edouard Villeneuve 30 Jun '14

30 Jun '14

Package: not_applicable Hello, We are trying to move from NX to X2Go. One of our tools is called Questa Sim (EDA tool from Mentor Graphics). When we used to run it from NX, no issues. When we use it with X2Go, we have color issues: · What was white or yellow text on a black background, now shows as … black text on a black background, hence not readable. · While we can change colors in a preferences menu, unlike in NX, changing the text color in X2Go environment does not work Below are two screenshots: · One from NX, where yellow bar and text is readable · One from X2Go, where this bar and text have become black (on black background) Thanks, - Edouard [image: cid:image001.png@01CE7ED3.3A9ED4D0] [image: cid:image002.png@01CE7ED3.C3C30420] Edouard Villeneuve | IS Manager | PLDA Group | Cell : +33 (0) 670 409 549 | http://www.plda.com/

Bug#122: x2goclient takes about 30s to detect if application was closed
by Christoph Mathys 29 Jun '14

29 Jun '14

Package: x2goclient Version: 4.0.0.3 I forward a single application using from Ubuntu 12.04 to Windows 7. When I close this application, the window disappears almost instantly. But x2goclient continues to show the session as active for about 30s after I closed the application. I tested this with gedit and kdiff3. The server uses x2goserver 4.0.0.0-0~640~precise1.

Bug#169: Usability: Too easy to start a session by clicking anywhere in the profile box
by Dan Halbert 29 Jun '14

29 Jun '14

Package: x2goclient Version: 4.0.0.3 It's a little too easy to start a session in the X2Go client window. A click anywhere in a profile box (it's sort of a gian button) will start a session, unless one clicks on one of the narrow setting lines or the lower right-hand pull-down-menu triangle. If I'm aiming for one of those spots but miss, a session starts. I'd rather not have the whole profile box sensitive like that. A "Connect" button or icon would be a little safer. I also remember the first time I tried to use X2GoClient, I was surprised there was no "Connect" button, and had to guess that a click on the profile box would start a session.

Package: x2goserver Version: 4.0.1.6-0~712~precise1 Hello, It is not possible to resume the session with windows X2Go client V.4.0.1.0 , even if it is correctly suspended before.
