Bug#1281: Ctrl-Alt-M echoed to server
by Roland Kaufmann 04 Apr '18

04 Apr '18

Package: x2goclient Version: 4.1.1.1 When connecting to an X2Go server (version 4.1.0.0-0~1517~ubuntu12.04.1; arch x86_64, with nxagent version 2:3.5.99.16-0~201803162252~ubuntu12.04.1) using X2Go client (version 4.1.1.1-0~1719~ubuntu16.04.1; arch x86_64), in fullscreen mode, the keyboard shortcut Ctrl-Alt-M does not only minimize the client window, but it is also echoed into the application currently running on the server (as if it was pressed locally on that machine). I would expect the Ctrl-Alt-M shortcut key to be swallowed by the client, so that it does not reach the server.

Unable to execute: mate-session on new Fedora 27 install with nightly builds enabled
by Robert Kudyba 03 Apr '18

I’m hoping I don’t have the same situation I had before mixing old nx-libs with new ones perhaps these logs and version numbers will help find something I’m missing. X2Go from a Mac fails with Unable to execute: mate-session Apr 3 10:51:19 erdos systemd-logind[1858]: New session 592 of user kudyba.

Bug#1276: VcXsrv windows xserver crashes when trying to resume a fullscreen session
by x2go＠0bl.net 29 Mar '18

29 Mar '18

I have the same problem even with a single monitor system. Environment: - x2goserver 4.1.0.0 (ArchLinux) - Client: Windows 10 Build 1709 - Desktop: xfce4 Steps to reproduce: - Open Windows client (4.1.1.1), start a new session with "Connect to local desktop" (resolution does not seem to matter, but I'm using windowed 1650x1010) - Click "Full access" - As soon as the "New session" window appears, x2goclient crashes. Older versions of both the client and server (tried different hardware/distros on the server also) exhibit the same issue. Backtrace from Dr. Mingw of the debug exe: vcxsrv.exe caused an Access Violation at location 000000006E34F608 in module MSVCR120.dll Reading from location 0000000006E04648.

Bug#1279: Idle connection crashes and is unable to resume
by Michael Schneider 28 Mar '18

28 Mar '18

Package: x2goserver Version: 4.1.0.0 I recently upgraded x2goserver for Ubuntu 16.04.1. The output of x2goversion is below x2golxdebindings: 1.0.2.4 x2gomatebindings: 0.0.1.5 x2goserver: 4.1.0.0 x2goserver-common: 4.1.0.0 x2goserver-extensions: 4.1.0.0 x2goserver-fmbindings: 4.1.0.0 x2goserver-printing: 4.1.0.0 x2goserver-x2goagent: 3.5.99.16 x2goserver-xsession: 4.1.0.0 After doing so now Idle sessions crash and are unable to resume. The `nxagent` process for the user begins eating up 100% CPU. When I log in I get a pulse audio error. If I suspend the session (close the client without logging out) then reopen it right away (with just a few minutes) I am able to successfully resume the session. However, if I leave the connection active but idle for sometimes 15 minutes sometimes a few hours, the connection terminates. The client displays an error about the connection being terminated. When I try to log back in. The client pops up an error about the remote proxy and won't let me connect. To reconnect I have to log in with putty and manually terminate the session using: $ x2goterminatesession <session_id> Below are excerpts from syslog and session.log *Syslog* Mar 27 14:23:39 myhost systemd[1]: Started Session 5372 of user <user>.

Hi, sorry for the late reply. I was on vacation last week. I solved it with the configuration change of Samba Server. Following parameters have been set in /etc/smb/smb.conf: template homedir = /home/%U winbind use default domain = yes the plus "+" in the username is just shortened and the real username has no plus in it. It is all about the "\" The error I got was not so clear, that it is a problem with the backslashes in the username. A hint in the client or elsewhere would be fine.

A backslash is the default winbind separator *, and a plus sign very common to use. I didn't see any other characters used (yet), but making it a config variable would indeed help for these rare cases and gives admins some flexibility.

Bug#1277: fix default keyboard shortcut of viewport_move_left
by René Genz 21 Mar '18

21 Mar '18

Package: x2goagent Version: 3.5.0.33 Tag: patch The viewport keyboard shortcuts are bound to: * Ctrl+Alt+arrow keys for up, right, down * Ctrl+Shift+Alt+arrow keys for left This patch removes the '+Shift' for moving left. Hence, all viewport movement shortcuts use the same set of keys. I guess the '+Shift' was a copy-paste error. I dare not to open dedicated bug reports for these minor problems: On the website: https://wiki.x2go.org/doku.php/wiki:advanced:nx-keyboard-shortcuts please, rename the file: keystroke.cfg to: keystrokes.cfg For the bug submission I noticed on the website: https://wiki.x2go.org/doku.php/wiki:development:join-the-team you can read: Whenever you find a bug, an improvement, try to fix it, try to implement it. what you come up with → Send it as a patch to the developers' mailing list for reviewing.

Effective username not correct in Session ID because of plus sign in user names (Windows AD / Samba4)
by j.rohde＠nederlandlive.nl 20 Mar '18

20 Mar '18

Hi All, I've encountered a problem with the latest ppa packages (stable: 4.1.0.0-0~1517~ubuntu14.04.1). My system runs a samba4 server and my users are named: "DOMAIN+user" (the plus sign is a literal plus / AD style). When the session ID for x2go is formed/created the plus sign is stripped from the user name apparently. This gives (at least) a problem when changing the state in de DB: In /usr/share/perl5/X2Go/Server/DB/SQLite3.pm line 403 an attempt is made to get the 'effective' user name, but that will never happen because of the stripped out plus sign. As a consequence sessions are not terminated/suspended/etc.. For now i've made it so my $effective_user == $realuser, but this breaks desktop sharing functionality. Sort of the same bug was present in earlier versions, but was fixed later on. I've tried to find the script/code where the session id is formed, but could not find it yet. I guess that's where this should be fixed though. Is it possible to get support for these style of user names?! Best, Joost
