x2goclient-3.99.2.1 plugin crash

I can get the x2goclient firefox plugin to reproducibly crash. This crash happens once one clicks on the blue X2go splash when the plugin is loaded.

Fullscreen RDP sessions with X2Go
by Mike Gabriel 03 Jul '12

03 Jul '12

Hi John (Sullivan), I currently try to provide Windows 2008 Terminal Services through X2Go and I stumbled over an issue I was not aware of. In fullscreen mode the X2Go client-side does not get a keyboard grab on the rdesktop session window. I can move+click with the mouse, I can view the rdesktop login screen, but I cannot type. This is with pyhoca-gui and x2goclient. The problem does not occur with rdesktop running in a Window (rootless, but not fullscreen). I then hacked PyHoca-GUI a little and launched rdesktop (-f) not as a rootless application (which is the default), but inside an agent desktop session (type "D"). Then the keyboard grab is there. Have you an idea on this? I know that you provide RDP session through X2Go quite often. Thanks for any info, Mike -- DAS-NETZWERKTEAM mike gabriel, rothenstein 5, 24214 neudorf-bornstein fon: +49 (1520) 1976 148 GnuPG Key ID 0xB588399B mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

Cut & Paste between 2 Ubuntu servers
by UWP 03 Jul '12

03 Jul '12

Hi! I have this problem since a long time: cut & paste in the x2goclient itself (same machine to same machine) works perfectly. But to get the clipboard-stuff out of the x2goclient (and vice versa) to the main machine is not possible. Since 1 week I got precise pangolin (12.04) on both of my machines, they have these packages: dpkg -l|grep x2go ii python-x2go 0.2.0.5-0~825~precise1 Python module for X2Go client support ii x2goagent 2:3.5.0.13-0~241~precise1 X2Go agent ii x2goclient 3.99.2.1-0~229~precise1 X2Go Client application (Qt4) ii x2godesktopsharing 3.0.1.4-0~68~precise1 share X2go desktops with other users (via shadow sessions) ii x2goserver 3.1.1.1-0~549~precise1 X2Go server daemon scripts ii x2goserver-extensions 3.1.1.1-0~549~precise1 X2Go server daemon scripts (extensions) The packages are coming from the ubuntu-PPA http://ppa.launchpad.net/x2go/stable/ubuntu I guess this is up2date? But the problem stays. It's a full desktop access. Do you need more informations? Thanx, Udo

The Windows version of PyHoca-GUI will be available within the next 48 hours. The new PyHoca-GUI and Python X2Go versions are mainly bugfixing releases. The new X2Go Gnome(2) Bindings package fixes a problem with unmounting of client-side shares if the user's HOME is mounted via NFS. Note: this package is only installable on GNOME 2 installations (Ubuntu Lucid, Debian squeeze). We are thinking about how to upgrade this package for usage with GNOME 3. light+love, Mike python-x2go (0.2.0.6-0~x2go1) RELEASE; urgency=low * New upstream version (0.2.0.6) - Ignore non-master sessions before calling the foldersharing- not-available hook. - Add several double underscore method aliases in X2goSession class. - Add several double underscore method aliases in X2goClient class. - Avoid double notifications on SSHFS being unavailable for the authenticated user. - X2goSession.HOOK_printing_not_available(): Fix log message. -- Mike Gabriel <mike.gabriel(a)das-netzwerkteam.de> Mon, 02 Jul 2012 20:54:37 +0200 pyhoca-gui (0.2.0.1-0~x2go1) RELEASE; urgency=low * New upstream version (0.2.0.1): - Drop Encoding key from .desktop file (deprecated as of latest FreeDesktop.org specs. - Fix grammatical error in man page. - Let logon window and session title window be positioned at top of screen also for ,,gnome-fallback'' sessions. - Let logon window and session title window be positioned at top of screen also for ,,ubuntu-2d'' sessions. - Provide empty template for the French translation of PyHoca-GUI. - Let logon window and session title window be positioned at top of screen also for ,,openbox-gnome'' sessions. -- Mike Gabriel <mike.gabriel(a)das-netzwerkteam.de> Mon, 02 Jul 2012 20:26:40 +0200 x2gognomebindings (2.0.1.6-0~x2go1) RELEASE; urgency=low * New upstream version (2.0.1.6): - Make sure we run fusermount from within a directory that the user has read access to. * Depend on desktop-file-utils (postinst uses script ,,update-desktop-database''). -- Mike Gabriel <mike.gabriel(a)das-netzwerkteam.de> Mon, 02 Jul 2012 14:31:41 +0200 -- DAS-NETZWERKTEAM mike gabriel, dorfstr. 27, 24245 barmissen fon: +49 (4302) 281418, fax: +49 (4302) 281419 GnuPG Key ID 0xB588399B mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

X2Go release: x2goserver
by Mike Gabriel 29 Jun '12

29 Jun '12

Dear all, The X2Go Project is proud to announce another X2Go component releases: - x2goserver (3.1.1.2) The new X2Go server packages will be available in our stable repositories (Debian, Ubuntu) within the next 24h. This release fixes several issues: (1) x2gocleansessions was broken quite a bit. Crashes occurred when sessions have been found running and x2gocleansessions tried to shut them down. Also the occuring zombie processes caused by x2gocleansessions and observed by some of you should now be gone. (2) With PostgreSQL as session db backend, the display would increment and increment and increment and... (3) Fixes session startup failures with pam_tmpdir.so being in use for user sessions. (4) Mount client-side shares to /tmp/.x2go-<user>/{media,spool,mimebox}. So we reduced this to one location. (5) NX session.log get now written to /tmp/.x2go-<user>/<session.log>. This fixes a broken x2gocleansessions script if HOMES are mouted via NFS (+Krb5). light+love, Mike x2goserver (3.1.1.2-0~x2go1) RELEASE; urgency=low [ Mike Gabriel ] * New upstream version (3.1.1.2): - Place session.log into /tmp directory, make x2gocleansessions and x2golistsessions_root work even if home directories are mounted via NFSv4+Krb5 and not accessible by root. - Use -fPIE gcc (position independed executable) for building x2gosqlitewrapper.c (as suggested by Jan Engelhardt). - Clean up session.log tmp directory if empty. - Move all X2Go tmp folders (mount points) to /tmp/.x2go-<user>. Make sure all tmp folders get removed if not used any more. Drop symlink ~/media if no client-side folders are mounted into a session. - Fix crashes of x2gocleansessions due to faulty syslog calls. - Drop redundant hostname calls in x2gocleansessions. - Launch x2goagent with $NX_TEMP=/tmp, otherwise it will fail to create the X11 Unix domain sockets. -- Mike Gabriel <mike.gabriel(a)das-netzwerkteam.de> Fri, 29 Jun 2012 17:44:57 +0200 -- DAS-NETZWERKTEAM mike gabriel, dorfstr. 27, 24245 barmissen fon: +49 (4302) 281418, fax: +49 (4302) 281419 GnuPG Key ID 0xB588399B mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

unscheduled bugfix release of , , NX (redistributed)'': 3.5.0.14
by Mike Gabriel 29 Jun '12

29 Jun '12

Dear all, Today Alex and I could eliminate another bug (introduced by ourselves) in nxagent/x2goagent. A couple of applications had lost their window decorations if the server is Debian wheezy / Ubuntu maverick or newer. Mostly affected were Qt applications. @FreeNX developers: Please note, this bug is also present in current FreeNX nx-X11 code (as found on Launchpad). We have removed the following patch from our patchset to get this fixed: http://code.x2go.org/gitweb?p=nx-libs.git;a=blob;f=debian/patches-refused/1… Still open issue: Unfortunately, there is still no fix for the resume problem in current nx-X11. The Debian+Ubuntu packages of this NX (redistributed) release are already available in the known (http://wiki.x2go.org/doku.php/download:start) repositories. Greets, Mike nx-libs (2:3.5.0.14-0) RELEASE; urgency=low [ Mike Gabriel ] * New upstream release of nxagent (3.5.0-9). * Adapt patch series (all hunks succeeded automatically). * Drop patch: 120_nxagent_libcairo-null-source-drawables.full.patch, the issue has been fixed by NoMachine (TR05J02703). * Drop patch: 109_nxagent_locale-utf8-compound-text.patch, the patch causes Qt applications to be rendered without window decorations when running in rootless window mode. [ Mihai Moldovan ] * Add patch: 052_nxcomp_macos10-nxauth-location.full+lite.patch, change nxauth search location on Mac OS X to $NX_SYSTEM/nxauth to facilitate application bundle building. -- Mike Gabriel <mike.gabriel(a)das-netzwerkteam.de> Thu, 28 Jun 2012 14:52:24 +0200 -- DAS-NETZWERKTEAM mike gabriel, dorfstr. 27, 24245 barmissen fon: +49 (4302) 281418, fax: +49 (4302) 281419 GnuPG Key ID 0xB588399B mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

unscheduled bugfix release of ,,NX (redistributed)''
by Mike Gabriel 27 Jun '12

27 Jun '12

Dear all, due to the great contribution of Jim Burnes we are able to bump an unscheduled bugfix release of NX (redistributed) aka x2goagent that fixes recently observed crashes of X2Go occuring on systems that had been upgraded to libcairo >= 1.12.1. The patch--as stated by its author--is still in alpha development state but it definitely fixes crashes of GTK applications under KDE, resp. startup failures of the GNOME3 fallback desktop of recent Debian wheezy/sid X2Go installations. @Developers: the patch still needs some reviewing and possibly improvements, so please take a look: http://code.x2go.org/gitweb?p=nx-libs.git;a=blob;f=debian/patches/120_nxage… Greets, Mike nx-libs (2:3.5.0.13-0) RELEASE; urgency=low [ Mike Gabriel ] * Let nxagent Debian package depend on xfonts-base.

[X2Go-Announcement] New X2Go releases: x2goclient, pyhoca-gui, pyhoca-cli, python-x2go
by Mike Gabriel 25 Jun '12

25 Jun '12

Dear all, The X2Go Project is proud to announce a couple of new X2Go component releases: - x2goserver (3.1.1.1) - pinentry-x2go (0.7.5.4) All new packages will be available in our stable repositories (Debian, Ubuntu) within the next 24h. In X2Go server we have put some focus on automatic client keybaord recognition. Put ,,auto'' as keyboard type/model in x2goclient and check your keyboard settings within the X2Go session with ,,setxkbmap -print''. PyHoca-GUI already has a widget in the session profile management window to enable auto-keyboard recognition. Also, this version of X2Go Server now has Unity and GNOME3 session support. Use X2Go Client 3.99.2.1 or PyHoca-GUI 0.2.0.x to enjoy Unity session on Ubuntu servers running X2Go. Also a fix for an error that occurred when unmounting client-side shares on NFS homes has been added to this release. The pinentry-x2go project experienced a very comprehensive code clean up. No new features have been added, but the X2Go pinentry fork has been prepared for upload to Debian. light+love, Mike X2Go Server changes =================== x2goserver (3.1.1.1-0~x2go1) RELEASE; urgency=low [ Mike Gabriel ] * New upstream version (3.1.1.1): - Add/fix Python X2Go folder sharing/unsharing support from Windows. - Handle whitespace in folder names appropriately. - Allow .desktop file parameter Terminal=... to pass through to X2Go client-side. - Avoid error messages in x2gocmdexistmessage if cmdoutput file could not be found. - Provide nx-X11 libraries for applications launched via x2goruncommand. - Add feature X2GO_SERVERSIDE_DESKTOPCOMMANDS. Let client provide a generic desktop shell command (GNOME, UNITRY, KDE, etc.) which then gets translated into an executable command by x2goruncommand. - Detect desktop session mode to use for Ubuntu precise and later. - Complete UNITY/GNOME support for Ubuntu/Debian. - Use ,,-nolisten tcp'' option when evoking x2goagent from within x2gostartagent. - Export NX_ROOT=$HOME/.x2go in x2gostartagent. Makes the keyboard file in X2Go session cache directory. - Add support for client-side keyboard detection. Moved script x2gosetkeyboard from x2goserver-pyhoca into x2goserver package. - Make x2gosetkeyboard set the client-side keyboard on session start and resume if usekbd is set to True and the keyboard type is set ,,auto''. - Reset keyboard settings to pc104/us before setting client-side keyboard parameters. - For finished sessions purge all mount points that still hover in the DB's mounts table. - Make sure we run fusermount from within a directory that the user has read access to. * Depend on x2goagent (>= 2:3.5.0.12), make sure that x2goagent has the patch 105_nxagent_export-remote-keyboard-config.full.patch included. -- Mike Gabriel <mike.gabriel(a)das-netzwerkteam.de> Thu, 21 Jun 2012 14:16:08 +0200 Pinentry X2Go changes ===================== pinentry-x2go (0.7.5.4-0~x2go1) RELEASE; urgency=low * New upstream version (0.7.5.4): - Drop mdate-sh and texinfo.tex from /doc folder (autotools build cruft). -- Mike Gabriel <mike.gabriel(a)das-netzwerkteam.de> Thu, 14 Jun 2012 09:47:09 +0200 pinentry-x2go (0.7.5.3-0~x2go1) unstable; urgency=low * Update of copyright information in several file headers. -- Mike Gabriel <mike.gabriel(a)das-netzwerkteam.de> Wed, 13 Jun 2012 17:11:48 +0200 pinentry-x2go (0.7.5.2-0~x2go1) unstable; urgency=low * New upstream version (0.7.5.2): - Strip code project down to its essentials, remove a lot of unneeded cruft. - Make code tree fully build with autotools, see README file for further info. - Replace string pinentry-qt with pinentry-x2go. * Make dh_clean remove all build cruft. -- Mike Gabriel <mike.gabriel(a)das-netzwerkteam.de> Wed, 13 Jun 2012 15:11:19 +0200 -- DAS-NETZWERKTEAM mike gabriel, dorfstr. 27, 24245 barmissen fon: +49 (4302) 281418, fax: +49 (4302) 281419 GnuPG Key ID 0xB588399B mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…
