Bug#1386: Popup plasmoids flicker and disappear when a remote application is in focus
by Tristan Miller 23 Mar '21

23 Mar '21

Package: x2goclient Version: 4.1.1.1 I use X2Go to run single applications remotely and have them appear on my local Plasma desktop. When such a remote application window has focus, it prevents me from opening most pop-up plasmoids on my local machine. The plasmoids flicker and then disappear. STEPS TO REPRODUCE 1. Use X2Go to launch a single application remotely. 2. Give the remote application focus (for example, by Alt-Tabbing to it or clicking on it). 3. Do some action that causes a local plasmoid window to pop up. For example, click on the Application Launcher to try to show the application list, or click on the Digital Clock to try to show the calendar, or click on a group entry in the Task Manager to try to show the list of windows, or press Alt+F2 to try to bring up KRunner. OBSERVED RESULT 4. The popup window appears for a few milliseconds and then disappears. EXPECTED RESULT 4. The popup window should appear and then persist. SOFTWARE/OS VERSIONS KDE Plasma Version: 5.12.8 KDE Frameworks Version: 5.45.0 Qt Version: 5.9.4 OS: openSUSE Leap 15.0 x2goclient: 4.1.1.1 x2goserver: 4.1.0.4 ADDITIONAL INFORMATION The video at <https://bugs.kde.org/attachment.cgi?id=119625> shows the bug. It shows a portion of my Plasma panel that includes the Application Launcher, the Pager, and part of the Task Manager. Claws Mail is running remotely via X2Go and one of its composer windows has focus. I am clicking repeatedly on the Application Launcher. You can see the pop-up window briefly flickering and disappearing. As far as I can tell, the problem happens only when an application run via X2Go has focus. The problem is not reproducible with applications run remotely via plain SSH. Not sure if this is a KDE/Plasma problem or an X2Go problem, so I have reported this also on the KDE Bugzilla: <https://bugs.kde.org/show_bug.cgi?id=406882>

Bug#1534: session.log fills up root filesystem
by Nico van Vliet 22 Mar '21

22 Mar '21

package: x2goserver version: 4.1.0.3 Cannot write data to system activity file: No space left on device Just use X2Go client on Windows10 (and possibly others) and suspend and reconnect a lot to the server. X2Go keeps writing to the session.log file. Example: # ls -l /tmp/.x2go-deshmane/C-deshmane-79-1615026580_stDXFCE_dp32/session.log -rw------- 1 deshmane dkdvlp 2037804631 Mar 22 12:25 /tmp/.x2go-deshmane/C-deshmane-79-1615026580_stDXFCE_dp32/session.log tail /tmp/.x2go-deshmane/C-deshmane-79-1615026580_stDXFCE_dp32/session.log nxagentPendingEvents: Returning error with display down. nxagentPendingEvents: Returning error with display down. nxagentPendingEvents: Returning error with display down. nxagentPendingEvents: Returning error with display down. nxagentPendingEvents: Returning error with display down. nxagentPendingEvents: Returning error with display down. nxagentPendingEvents: Returning error with display down. nxagentPendingEvents: Returning error with display down. nxagentPendingEvents: Returning error with display down. nxagentPendingEvents: Returning error with display down.

Bug#1530: TLS intermediate certificate seems to be "wrong"
by Tim Landscheidt 08 Mar '21

08 Mar '21

Package: wiki.x2go.org While checking URLs with LWP/curl, I noticed that wiki.x2go.org fails: | [tim@passepartout ~]$ curl https://wiki.x2go.org/ | curl: (60) SSL certificate problem: unable to get local issuer certificate | More details here: https://curl.haxx.se/docs/sslcerts.html | curl failed to verify the legitimacy of the server and therefore could not | establish a secure connection to it. To learn more about this situation and | how to fix it, please visit the web page mentioned above. | [tim@passepartout ~]$ Staring at "openssl s_client -connect wiki.x2go.org:443", https://www.ssllabs.com/ssltest/analyze.html?d=wiki.x2go.org and https://letsencrypt.org/certificates/ suggests to a layman that the server certificate is signed by the R3 certificate, but the X3 certificate is sent along?

Bug#1527: native X11 fonts stop being rendered as the desktop is shared; functionality is restored on unsharing.
by Enrico Bertocchi 27 Feb '21

27 Feb '21

Package: x2goserver Version: 4.1.0.3-4 (amd64, devuan Beowulf) Running, let's say "xfd -fn fixed" or any other sofware whose GUI is based on native X11 fonts (mwm) from within a remote x2go session (DISPLAY=:50), strings are rendered correctly until a second connection to such display (via the "x2go/x11 Desktop Sharing" facility) is established on the same :50 display, even with the same user. As soon as the connection is established, X11 fonts rendering stops for both the clients and all X11 clients which rely on such feature (e.g. mwm, or xfd) are shown with blank text boxes; applications which rely on different font technologies (e.g. the sakura terminal) are not affected. As soon the second connection is closed, font rendering is restored for the initial client, and writings reappear on the next window refresh. Such behavior is consistently reproduced at every attempt. Both client connections are originated from the same Centos 8 machine, with x2goclient 4.1.2.2 and disabled "set display DPI setting" option. Sincerely -- Enrico Bertocchi

Bug#1072: X2Go Client: top 24 pixels in fullscreen session do not respond to mouse clicks
by Chris Martin 09 Feb '21

09 Feb '21

Package: x2goclient Version: 4.0.5.1 I am trying to start a full screen X2Go session which 1. takes up the entire display, and 2. responds to my mouse clicks everywhere in the session, but cannot accomplish this with any combination of settings. Client OS: Debian Jessie / 8 / Stable, GNOME 3 desktop environment Client X2Go Client: 4.0.5.1 and 4.0.3.1 Server OS: Xubuntu 16.04 LTS Server x2goserver version: 4.0.1.19 Server x2goserver-xsession version: 4.0.1.19 When I choose "fullscreen", I get different behavior intermittently: 1. The client spawns across the entire screen but the *top panel inside the X2Go session* does not respond to any mouse clicks. I suspect the panel in my GNOME session running the X2Go client (which occupies the same pixels behind the panel inside the X2Go session) is stealing mouse focus. My mouse pointer turns black instead of white when I hover over the top 24 pixels or so, inside the X2Go session. 2. The client spawns what I would call a "maximized window". The top of the screen is still consumed by the title bar of the X2Go window, and the panel of the enclosing GNOME session in which the X2Go client is running. I have observed both cases 1 (most common) and 2 with X2Go Client 4.0.5.1, and only case 1 with X2Go client 4.0.3.1. When I choose "Display 1" in the Input/Output settings, the X2Go session displays only in the upper-left quadrant of my display; the rest of the screen is black. Thank you, Chris Martin

Bug#1518: x2go is aborted: unable to open display
by simona bellavista 06 Feb '21

06 Feb '21

Package: X2Go Client Version: 4.1.2.2 I work on OSX client. I try to connect to a remote server, and the connection fails. I was able to connect until 3 days ago, I did not change anything that I can remember. I get the following error message: Error: Aborting session with 'Unable to open display 'nx/nx,options=/tmp/.x2go-user/C-user-173-1610379165_stDXFCE_dp32/options:173''.

Upcoming Debian 11 freeze
by Mike Gabriel 27 Jan '21

27 Jan '21

Hi Mihai, Stefan, Alex, Uli, etc. the Debian 11 freeze is ahead (last uploads of new upstream releases are possible on Feb 6th/7th). I'd like to see some of the X2Go components released before that date (esp. the x2gothinclient, x2goclient, x2goserver and also nx-libs (already discussed with Uli)). @Mihai: is that a feasible thing to do???
