Hi, some time passed, but finally I found the time to do a testrun on a dedicated setup based on upstream arctica libraries my colleague compiled to deb packages and installed on a VM. The currently tested version is a bit outdated from branch 3.6.x: ---- snip ---- nx-libs$ git log -1 commit 9acd13e50c3bde9105f6143922028f0de0d4ae50 Author: Mike Gabriel <mike.gabriel(a)das-netzwerkteam.de> Date: Mon Dec 19 15:03:09 2016 +0100 release 3.5.99.3 nx-libs$ git remote -v origin git://github.com/ArcticaProject/nx-libs.git (fetch) origin git://github.com/ArcticaProject/nx-libs.git (push) ---- snip ---- The behavior is the same as before, the session dies at some time during some interaction with the tools window.

Bug#873: Drop Xinerama / LD_LIBRARY_PATH related code from x2goruncommand for nxagent >= 3.5.99.0
by Mike Gabriel 21 Nov '18

21 Nov '18

Package: x2goserver Severity: normal Version: 4.1.0.0-preview As the Xinerama magic will be soon moved from libNX_Xinerama.so into the programs/Xserver/hw/nxagent code, all Xinerama specifc stuff in x2goruncommand becomes obsolete if nxagent >= 3.5.99.0 is used server-side. The nxagent >= 3.5.99.0 will be able to handle Xinerama stuff all by itself. No external xinerama.conf is required, applications running server-side can use the X.Org client libraries, no hack for injecting libNX_X11, libNX_Xext and libNX_Xinerama into the library path is needed anymore. In fact, the libNX_Xinerama library will be dropped completely in nx-libs >= 3.5.99.0 (aka 3.6.x).

Bug#818: x2goserver: client-side folder sharing broken on Ubuntu 10.04
by Mike Gabriel 21 Nov '18

21 Nov '18

Package: x2goserver Severity: normal Version: 4.0.1.19 Hi all, x2goserver: client-side folder sharing is broken on Ubuntu 10.04 since X2Go Server 4.0.1.19. REASON: ------- I just discovered that the "timeout" command that we have started using in /usr/bin/x2gomountdirs since 4.0.1.19 of X2Go Server is normally shipped via the essential .deb package "coreutils". Normally, it is not necessary to add dependencies for essential packages. However, on Ubuntu 10.04, the timeout command is not shipped with the coreutils package but with a separate package called "timeout". There you have to explicitly install the "timeout" .deb package. So, basically in X2Go Server's debian/control file we need to add timeout | coreutils, under Depends: of bin:package x2goserver. However, as Ubuntu 10.04 will reach End of Life probably before the next X2Go Server release will come out, I am unsure if we should still change this. Please other devs give feedback, Mike -- DAS-NETZWERKTEAM mike gabriel, herweg 7, 24357 fleckeby fon: +49 (1520) 1976 148 GnuPG Key ID 0x25771B31 mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

Bug#627: X2Go Server fails to start Trinity when it is installed under /opt/trinity/
by Michael DePaulo 21 Nov '18

21 Nov '18

package: x2goserver version: 4.0.1.16 severity: normal If you install the Trinity Desktop Environment on Ubuntu 12.04 from the official Trinity project's repo[1], x2goruncommand assumes that for the "TRINITY" session it needs to run: /usr/bin/starttrinity However, the session fails to start because that file exists at this path instead: /opt/trinity/bin/startkde I am about to commit a fix for this. x2goruncommand will check for /opt/trinity/bin/startkde and run that if it exists. Otherwise, it will default to running /usr/bin/starttrinity . [1] https://www.trinitydesktop.org/wiki/bin/view/Documentation/UbuntuBinaryInst…

Bug#873: suggestion for how to handle Xinerama from NX 3.6.x in X2Go
by Mike Gabriel 21 Nov '18

21 Nov '18

Hi Mihai, hi Alex, the new RandR based Xinerama is about to be merged to the nx-libs 3.6.x branch. Here are some ideas how to make the feature addressable in X2Go. 1. X2Go Client can server-side query x2gofeaturelist, it outputs the string X2GOAGENT_RANDRXINERAMA. If that string is in x2gofeaturelist, then the new Xinerama code is present in x2goagent/nxagent. 2. We are about to add a xinerama={0,1} NX option for the NX options file (Ulrich is probably reviewing right now...). This should be used through NX proxy (I guess) for setting up Xinerama in X2Go Agent. It works on session startup and session resumption. 3. One can disable Xinerama completely via cmdline switch for x2goagent: -disablexineramaextension. My suggestion is: o you keep the xinerama.conf file with X2GOAGENT_RANDRXINERAMA, but put "enabled" or "disabled" into it o the "enabled" switch is rather for human beings, because the real enabling takes place via NX options o if "disabled" is set, then x2gostartagent should notice that and add -disablexineramaextension Also, -disablexineramaextension should be added (commented out, of course, thus for reference) to /etc/x2go/x2goagent.options. So far from Uli's and Mike's Xinerama hacking frontier...

Bug#28: Seems to be fixed in newer versions
by Ulrich Sibiller 21 Nov '18

21 Nov '18

Well, looking at the source of the current libxfixes (of Ubuntu Trusty) I can find no XFIXES version 6 code. Additionally libxfixes_5.0.1-1ubuntu1.diff.gz contains this changelog update: + -- Julien Cristau <jcristau(a)debian.org> Tue, 14 May 2013 10:12:48 +0200 + +libxfixes (1:5.0-4ubuntu6) raring; urgency=low + + * Drop the v6 protocol. + I cannot test a full KDE setup here but I think at least the speculation that v6 could be the reason can be dropped. Do the kwin crashes still happen with Raring or any later release of (K)Ubuntu? (For Precise a backport might be necessary.)

Bug#1035: capture x2goruncommand debug output for x2gofeature X2GO_XSESSION
by Tor Perkins 21 Nov '18

21 Nov '18

Package: x2goserver Version: 4.0.1.19 Tags: patch Hello, I had recently had a problem with my /etc/xprofile file that prevented session startup. The details are not too important; it had to do with a difference of default shell (/bin/sh) being either /bin/dash or /bin/bash. After enabling the 'debug' loglevel on the server, I still had no helpful output indicating what the problem might be... I did some ferreting about and noticed that x2goruncommand was not capturing cmd output when using x2gofeature X2GO_XSESSION (/etc/x2go/Xsession). The client side invocation of x2goruncommand (via sshlib) redirects remote command output to /dev/null, so it is also not preserved when using the client's --debug option... This small patch appends the missing output to an already existing debug file in x2goruncommand ($MESSAGE_FILE). With this in place, I was able to see the "smoking gun": cat ~/.x2go/C-user-50-1463156913_stD.Xclients_dp24/cmdoutput exec /root/.Xclients Loading profile from /etc/profile Loading profile from /root/.profile Loading profile from /etc/xprofile /etc/xprofile: 14: Bad substitution <-- whoop! The file is deleted (as before) if not at loglevel debug. Thanks for your consideration. - Tor

Bug#1274: x2goagent shows NoMachine logo in taskbar
by Mike Gabriel 21 Nov '18

Package: x2goserver-x2goagent Version: 4.1.0.0 Severity: serious When trying X2Go on MS Windows, the X2Go Agent window shows the NoMachine logo instead of the X2Go logo. Filing this against X2Go Server's agent wrapper, as it is not clear to me OTOH, if this needs fixing in the agent wrapper or in nx-libs's nxagent code itself.
