Bug#923: .xsession-x2go-errors improvements
by Orion Poplawski 22 Oct '15

22 Oct '15

Package: x2goserver Version: 4.0.1.19 First issue is that ~/.xsession-x2go-errors is always appended to so it grows forever. It should at least get rotated to .old file. Second is with shared NFS home directories, multiple X2Go sessions get logged to the same file which is confusing. I would suggest putting the host name into the log file name. -- Orion Poplawski Technical Manager 303-415-9701 x222 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion(a)nwra.com Boulder, CO 80301 http://www.nwra.com

x2go client session kicks user back to the session login screen
by Real, Elizabeth (392K) 21 Oct '15

21 Oct '15

Hello, I have a user who is not able to connect to an x2go server using x2go client for Mac. When I connect to the x2go server in question I am able to successfully connect and login. I’ve compared settings between the user’s and my Mac x2go client and they are identical. I’ve attached screen shots of the client session details. The last messages in the session are: * Info: Your session was closed before reaching a usable state. * Info: This can be due to the local X server refusing access to the client. * Info: Please check authorization provided by the remote X application. * Session: Session terminated at x2go client: v4.0.4.0 xquarts: v2.7.7 Tried uninstalling the x2go client and installing it again but that did not help. Same errors while attempt is made to connect to x2go server. Please advise. Thank you, Liz

I had a similar issue while connecting from X2Go Client v. 4.0.5.0 on MS Windows to X2Go Server v. 4.0.1.19-0~1064~ubuntu14.04.1 on Linux Mint 17.2 (using MATE session): the user was kicked back to the session login screen. The problem was in the .Xauthority* files in the user's home directory on the server side. One of the files was owned by the root, which was a problem. The user solved the issue by running the following command on the X2Go server: sudo rm ~/.Xauthority* Hope this helps. -- rpr.

Failing package and GPG Keys
by Real, Elizabeth (392K) 20 Oct '15

Hello, I need help to setup x2go server on a RHEL7 system. I configured the needed repos and installed perl modules file::which, config::simple, capture::tiny. However when I yum install x2goserver x2goserver-xsession I get an error/warning about the GPG keys not being correct, the repo is looking at http://packages.x2go.org/pub.key. If that does not work, where else can I go to get the keys? # yum install x2goserver x2goserver-xsession Loaded plugins: langpacks, product-id, subscription-manager Resolving Dependencies --> Running

Bug#958: Xsession startup: LD_LIBRARY_PATH in STARTUP var breaks Debian/Ubuntu/Mint session startups
by Mike Gabriel 19 Oct '15

19 Oct '15

Package: xserver-xsession Severity: important Version: 4.0.1.19 Several /etc/X11/Xsession.d scripts on Debian and Ubuntu (and other derivatives) fail (don't get executed), because they try to detect a variable $BASESTARTUP from $STARTUP which gets set during the Xsession startup mechanism. The detection code expects the session command (mate-session, startkde, xfce4-session, etc.) as the first element in $STARTUP when splitting the $STARTUP string at every blank. As x2goruncommand prepends a LD_LIBRARY_PATH to the STARTUP command (for enabling Xinerama in X2Go sessions), this distro-specific detection mechanism fails. Why report this issue to X2Go then (and not to Debian). Easy reasoning... With nx-libs 3.6.x, the Xinerama code will be completely rewritten and it won't be necessary to set a customer LD_LIBRARY_PATH anymore. Thus, we should make sure, your X2Go Xsession startups get aligned with distro-specific expectations.

Plans for a 4th X2Go Developer Online Meeting

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 [please respect the Reply-To header and do not crosspost to x2go-dev] Hi everyone, it's been a while since the last X2Go developer online meeting took place. I've talked to h1, who is in charge of coordinating these events, and he has indicated that 2015-10-22 would be the earliest date possible for him. Would you all please have a look at your calendars and keep that date in mind? I'm sure an official doodle listing this date as well as some alternatives will follow soon. With a little bit of luck, I will be able to attend it as well, undisturbed this time. Topics that I would like to see on the agenda: - - Call for Translations - seems like we need one, there's English-language text showing up in the German menus, which isn't good - who will handle: - the actual CfT? - merging the translations into the repo? - - Minor-Number client release - blocker: missing translations - release TBD when translations are complete - should happen soon - - Bug Triaging - we should browse through the list of open bugs - check for appropriate severities - see who's willing and able to tackle bugs (AKA "activity check") - come up with a list of who-does-what-by-when -> Intent: Public Roadmap for next releases Feel free to add more, in case I missed something. - -Stefan X2Go Project/Community Coordinator - -- BAUR-ITCS UG (haftungsbeschränkt) Geschäftsführer: Stefan Baur Eichenäckerweg 10, 89081 Ulm | Registergericht Ulm, HRB 724364 Fon/Fax 0731 40 34 66-36/-35 | USt-IdNr.: DE268653243 -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJWAu74AAoJEG7d9BjNvlEZwMoH/Rl/nTZSflQc2i7AhT6YgWQa D4txq6sQTAPNfYeMz8gVskxwFkoQxv0YlPKCQLdaCqdO8NmbpYIQ17uSRNc2R7Oi 99cHTqgiTSt/3RGaRMk47lSr+mrnxsV+5lRThC/HpKTMGTzNMwFIlzFiUDRFegIz ZIYHsBftEvsz6VwUUbhsm3uP/G0hI3GFxMpHzcTMYHsoSyIZm51/VEG5Az0xWD7Z SmKtexB+ThD74CsthYSH9f301peHj+pfvsOXIsuUqCmcXEKEoHeMhaFpM5BBVMFh 9Cu+V5q98Wu1PrlOnNTveKYzMzU01Z85XAISJxQTkvs7PPXhMqkUEdmwDOhzT2M= =lqiY -----END PGP SIGNATURE-----

Bug in Upgrade Process - Debian Wheezy/Jessie
by Stefan Baur 16 Oct '15

16 Oct '15

Hi everyone, I just stumbled over a nasty bug, but I'm not sure if it is a bug that is limited to X2Go, or if Debian/apt/dpkg is at fault here. Situation: I would like to upgrade a system from wheezy to jessie. This system is running X2Go stable. Step 1: s/wheezy/jessie/ in sources.list Step 2: apt-get update Step 3: Try any of the following: apt-get install x2goserver # when it's already present in # it's wheezy incarnation apt-get upgrade apt-get dist-upgrade and you will see that all X2Go packages remain in their wheezy state. Step 4: Force the installation of the exact version of x2goserver. apt-get -t jessie install x2goserver=4.0.1.19-0x2go2+git20150608.1064+jessie.main.1 And tadaa, we get a hint at what's going on: Reading package lists... Building dependency tree... Reading state information... The following packages were automatically installed and are no longer required: libfile-readbackwards-perl libglib1.2ldbl libgtk1.2 libgtk1.2-common libmozjs24d libnet-daemon-perl libnx-x11 libplrpc-perl libtommath0 xulrunner-24.0 Use 'apt-get autoremove' to remove them. Suggested packages: x2goserver-compat x2goserver-fmbindings x2goserver-pyhoca The following packages will be REMOVED: x2goserver-extensions x2goserver-printing x2goserver-xsession The following packages will be DOWNGRADED: x2goserver 0 upgraded, 0 newly installed, 1 downgraded, 3 to remove and 782 not upgraded. Need to get 85.5 kB of archives. After this operation, 360 kB disk space will be freed. Do you want to continue [Y/n]? apt-get believes it is DOWNGRADING even though we're actually trying to perform an update. Looking at the version numbers given... 4.0.1.19-0x2go2+git20150608.1064+jessie.main.1 4.0.1.19-0x2go2+git20150608.1064+wheezy.main.1 ... it becomes obvious - apt does a numerical/alphabetic sort, and the only difference in those two version strings is "jessie" vs. "wheezy", with the "w" in wheezy being "higher" than the "j" in jessie. Is this something we can fix on our own, by using numeric release numbers (7 for wheezy, 8 for jessie), or is this actually a bug that needs to be reported upstream, because maybe apt shouldn't act that way, and "latch" onto the release name instead of adding it to the numerical/alphabetic sort? If it is entirely our own bug, what should I file it against? Picking out a particular package doesn't seem to make sense, they will all be affected. Do we have a meta-category for that?
