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

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.

Bug#1344: Versioning in the launchpad ppa
by Jens Reyer 20 Nov '18

20 Nov '18

Package: launchpad.net Hi, the version of e.g. nx-libs in the X2Go nightly PPA at https://launchpad.net/~x2go is technically lower than the one in the official Ubuntu Bionic (18.04) archive: $ dpkg --compare-versions 2:3.5.99.16-0~201811100633~ubuntu18.04.1 gt 2:3.5.99.16-1 && echo "ppa version is bigger" || echo "ppa version is smaller" ppa version is smaller This would be correct if they had the same "upstream" content, so that the official package has precedence over the PPA one. However I assume that the nightly PPA ships newer "upstream" functionality. You may reflect this by changing the versioning to something like this (increase the upstream versioning part before the Debian revision -0): 2:3.5.99.16+201811100633-0~ubuntu18.04.1 $ dpkg --compare-versions 2:3.5.99.16+201811100633-0~ubuntu18.04.1 gt 2:3.5.99.16-1 && echo "ppa version is bigger" || echo "ppa version is smaller" ppa version is bigger Otherwise I have to "downgrade" the packages, in order to use the nightly builds instead of the older official Ubuntu bionic ones. For this to work I currently use apt pinning: $ cat /etc/apt/preferences.d/x2go-ppa Package: * Pin: release o=LP-PPA-x2go Pin-Priority: 1010 Thanks jre

Bug#1171: Create wtmp entry for x2go sessions
by Orion Poplawski 19 Nov '18

19 Nov '18

Package: x2goserver Version: 4.1.0.0 Severity: wishlist X2Go should write an entry to /var/run/utmp and /var/log/wtmp. This would allow currently logged inn users to be seen in the output of 'w', and 'last' would also list previous sessions.

Bug#1341: FreeRDP not working in x2go, requires BIG-REQUESTS extension
by Jens Reyer 19 Nov '18

19 Nov '18

Package: x2goserver-x2goagent Version: 4.1.0.2-0~1642~ubuntu1 Hi, freerdp (freerdp and freerdp2) doesn't work with current default x2go: ~~~~~ $ xfreerdp /size:1700x1000 /u:USER /p:PASS /v:192.168.50.142 /cert-ignore connected to 192.168.50.142:3389 X Error of failed request: BadLength (poly request too large or internal Xlib length error) Major opcode of failed request: 18 (X_ChangeProperty) Serial number of failed request: 41 Current serial number in output stream: 45 ~~~~~ The bug report for FreeRDP (https://github.com/FreeRDP/FreeRDP/issues/4920) came to the conclusion that it requires the BIG-REQUESTS extension, which is disabled in x2go. Indeed removing these lines in /etc/x2go/x2goagent.options fixes the issue: ~~~~~ # Disable BIG-REQUESTS, nx-libs does not implement this extension correctly. # Leads to all sorts of weird crashes if left enabled. X2GO_NXAGENT_DEFAULT_OPTIONS+=" -extension BIG-REQUESTS" ~~~~~ I'm using this for a day now without "weird crashes", but still assume it's probably not the best idea.
