Thanks a lot for contributing to X2Go!!! light+love X2Go Git Admin (on behalf of the sender of this mail) --- X2Go Component: src:x2goserver Version: 4.0.1.16-0x2go1 Status: RELEASE Date: Fri, 26 Sep 2014 00:36:32 +0200 Fixes: 122 302 397 406 407 458 468 495 506 511 520 523 524 543 547 558 569 572 573 574 599 605 606 617 619 Changes: x2goserver (4.0.1.16-0x2go1) RELEASED; urgency=low . [ Mike DePaulo ] * New upstream release (4.0.1.16): - Make X2Go Server aware of the Openbox desktop environment (Command: OPENBOX) (Fixes: #605) - Make X2Go Server aware of the IceWM desktop environment (Command: ICEWM) (Fixes: #606) - Support GNOME Flashback session (GNOME 3.8+) on distro releases such as Ubuntu 13.10+ and debian Jessie (NOTE: For most users, GNOME Flashback currently will not work. This requires that gnome-flashback.session actually be installed. Not every Linux distro has it available. It also requires that the gnome-session binary not require hardware 3D acceleration for said session. Currently, upstream GNOME and GNOME 3.8+ in all Linux distros do require this, only 3rd party builds do not. See X2Go bug #599 for example.) (Thanks Eugene San (eugenesan@gmail.com)) - Fix launching GNOME 3 Fallback session (GNOME 3.4 & 3.6) on distros other than Ubuntu and Debian (Fixes: #599) - Fix support for Cinnamon 1.4 (Linux Mint 13) (Fixes: #569) - Fix the logic for launching Cinnamon 2.0 and 2.2 (Linux Mint 17). (Fixes: #572) NOTE: Fixing this bug in x2goserver is not sufficient to make Cinnamon 2.0 & 2.2 to work properly with X2Go. Bug #150 in nx-libs is still a problem. Fixing this bug enables Cinnamon 2.0 and 2.2 to launch to their "fallback mode", which has many bugs and missing features when compared to "software rendering" mode (cinnamon2d), but is still better than nothing. * debian/rules: + Improve dh_auto_clean override. . [ Mike Gabriel ] * New upstream version (4.0.1.16): - Let x2goversion exit with an error if the X2Go component cannot be found. - Detect terminated sessions from NX log file. Also interpret a session as terminated if terminating just has started. - Detect started/starting/resumed/resuming sessions by explicitly scanning the NX session log file for those keywords. - Interpret NX sessions marked as "aborting session" as (not yet) terminated sessions. - Provide config option for server-side/global clipboard behaviour in x2goagent.options. (Fixes: #506). - Be aware of poly-instantiated /tmp directories bind-mounted under /tmp-inst. (Fixes: #406). - On suspend: Call x2goumount-session before sending SIGHUP to x2goagent. - Refuse client communcation if server-side hostname is not set up correctly (Fixes: #468). - Fix string comparison in x2goumount-session. - Fix problems with unmounting shared folders on session suspension/ termination. Remove extra parentheses from the fusermount execution call. (Fixes: #407). - Use type -p instead of which in x2goumount-session. Suppress output to stdout properly. - Use if--then--else--fi during x2goagent resuming in x2goresume-session script. - More reliably sync the NX session state with the status information in the X2Go session DB. - x2golistdesktops: Also detect sharable desktop sessions behind abstract kernel namespace sockets. - Add logcheck rules for X2Go Server. Thanks to Frank Werner for sending them in. - Correctly use diversions from stderr to stdout in shell commands. (Fixes: #520). - Don't die if no session state file is found, as it will break X2Go completely after upgrading from versions << 4.0.1.16 if sessions are still running/suspended during package upgrade. - Provide support for client-side choice of clipboard security. (Fixes: #524). - Use more quotes in x2goruncommand. - Detect the exit of rootless applications that forked to background on application execution. (Fixes: #122). - Make x2goruncommand more robust. - Don't fail Xsession startup if any of the profile scripts returns with an error. - Silently timeout in x2golistdesktops if calls to x2golistsessions and/or xwininfo don't produce output within one second. (Fixes: #543). - Allow email addresses as login usernames. (Fixes: #573). - Abort session startup if env var $USER or $SSH_CLIENT are not set. (Fixes: #558). - Allow length of username up to 48 characters (was: 32 characters). (Fixes: #574). - Abort session if env var $HOME is not set or if $HOME contains non-ASCII characters. (Fixes: #397). - Export XAUTHORITY env var in x2goruncommand to enable privilege upgrade for applications started via pkexec. (Fixes: #458). - x2gocleansessions: Don't print to stderr if the session state file cannot be found. This can happen during session startups. Report to system log instead. - Don't use Perl package File::ReadBackwards anymore. - Fix x2gormforward for 4.0.1.x release series (the X2Go::Log Perl module only exists in X2Go Server >= 4.1.0.0, the 4.0.1.x release series has to use x2gologlevel.pm in `x2gopath lib`. (Fixes: #617). - Pick x2gogetagentstate from 4.1.0.0 release series and adapt to usage with X2Go Server 4.0.1.x. (Fixes: #619). * debian/control, x2goserver.spec: + Update versioned D: x2goagent (>= 3.5.0.25). This assures that X2Go works with poly-instantiated /tmp directories. + Make sure x2gogetagentstate gets packaged in bin:package x2goserver. + Bump Standards: to 3.9.5. No changes needed. + Mark x2goserver-pyhoca bin:package as deprecated. + Drop D (x2goserver): libfile-readbackwards-perl. * x2goserver.spec: + Install {libdir}/x2go/x2gormforward into bin:package x2goserver. + Drop R (x2goserver): perl(File::ReadBackwards). . [ Oleksandr Shneyder ] * New upstream version (4.0.1.16): - x2gostartagent, x2golistsession, x2gosuspend-session and x2goresume-session getting agent state from ~/.x2go/C-$SID/state. This should help to avoid session damage. Remove nxcleanup. (Fixes: #302, #511). - Move session file to /tmp/.x2go-$USER. (Fixes: #523). - Fix x2gostartagent failures if kbd is not "auto". Remove comma at end of options file. - Set default value for clipboard to "both" in x2gostartagent and x2goresume-session. - Clean user SSHD process if connection between server and client lost. This should fix error "Global request tcpip-forward failed". (Fixes: #495, #547). . [ Orion Paplowski ] * x2goserver.spec: + Sync Fedora .spec file with our upstream-provided x2goserver.spec. ------------=_1411685138-21663-0 Content-Type: message/rfc822 Content-Disposition: inline Content-Transfer-Encoding: 7bit Received: (at submit) by bugs.x2go.org; 9 Jul 2014 21:57:25 +0000 X-Spam-Checker-Version: SpamAssassin 3.3.2 (2011-06-06) on ymir.das-netzwerkteam.de X-Spam-Level: X-Spam-Status: No, score=0.8 required=5.0 tests=BAYES_50,HTML_MESSAGE autolearn=ham version=3.3.2 Received: from mail-vc0-f170.google.com (mail-vc0-f170.google.com [209.85.220.170]) by ymir.das-netzwerkteam.de (Postfix) with ESMTPS id C88F65DB24 for ; Wed, 9 Jul 2014 23:57:21 +0200 (CEST) Received: by mail-vc0-f170.google.com with SMTP id hy10so8781315vcb.29 for ; Wed, 09 Jul 2014 14:57:19 -0700 (PDT) X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20130820; h=x-gm-message-state:from:content-type:subject:message-id:date:to :mime-version; bh=CM1H/QdzwcUufuX1NKoMpVTRxgTLuMJUDOxmuRSr3RY=; b=byRf5Xk95MYrgKSv9BDaSKuQkSSpdDmuvYhYybUo9RKT8hurMXCS80jCG+Jhn3+c/d dqCZfmQtE2XJeCaiKfaLNrOwVvD16ps5+Q3STVMawdqrp4inB/BALK5WLQH4stLomAfb vb0ItYDJbsHkcpyY/03LIkBWqeh/Nd5ULPM/GCgFnEkXA/ShNylq3TaOKkd0uNSF4OEl VOBJuPkr3SPAT6I/aF6x9UpytIj/jdrLR3zcW7wud3fIG8soTL33qEjJUpg5quc6ANk5 6aypsDfOu9TBja3MxiZSAmqhhWi4vxhntJoJYEoaD/bzavCr3oVhfFouS8GLFILwHF1n 0zUA== X-Gm-Message-State: ALoCoQnsvHoGPqMWwLSkeiZfeJ+G7u7XJ0vSmCVNjSgku6QcFv9ImY0BlMfVegN4CGUerOOzQb9u X-Received: by 10.52.157.164 with SMTP id wn4mr397250vdb.81.1404943039657; Wed, 09 Jul 2014 14:57:19 -0700 (PDT) Received: from [10.59.27.114] (97-64-141-154.client.mchsi.com.

Hi,  my = server had a =91weird=92 file in /tmp/.X11-unix/ for which xwininfo = would never return, locking up x2golistdesktops.

The = solution is to provide a timeout for the shell call to xwininfo. =  This can be accomplished either using the shell command =91timeout=92= or the Perl IPC::Run module = (as described in the first response to http://stackoverflow.com/questions/16918005/time-out-whe= n-using-system-cmd-in-perl).

For my = purpose, I=92ve used the shell timeout command. Patch = below.
