X2Go release day: x2goserver, x2goclient (adds support for Published Applications)
by Mike Gabriel 04 Apr '12

04 Apr '12

Dear all, The X2Go Project is proud to announce two new X2Go component releases: - x2goserver (3.1.1.0) - x2goclient (3.99.2.0) The new packages will be available in our stable repositories (Debian, Ubuntu) within the next 24h. The windows and Mac OS versions of x2goclient will probably be available tomorrow, as well. (PING: @Mihai, @Oleksandr). The Windows binary may get delay a little longer, as we are currently migrating the Windows development machine to another hoster, so we have to ask for your patience here. Sources and binary releases will be downloadable under this URL as soon as they are provided by the packagers. http://code.x2go.org/releases/ The new X2Go Server and Client versions add X2Go Published Applications support. This feature was sponsored/contracted by Stefan Baur (http://www.baur-itcs.de) The feature allows to export a server-side, user-individual as well as system-wide applications menu to the X2Go Client. We expect this feature to become higly attractive to Linux SaaS providers. Published Applications support will also be available in the next release of PyHoca-GUI, this (and also stabilizing PyHoca-GUI on Windows 7) is currently work in progress, sponsored by Dick Kniep (http://www.lindix.nl) light+love, Mike x2goserver (3.1.1.0-0~x2go1) RELEASE; urgency=low [ Mike Gabriel ] * New upstream version (3.1.1.0): - Syslog warnings have to be named ,,warning'' not ,,warn''. - Add usage output to x2goserver-run-extensions. - Fix syslog output of x2goserver-run-exentions. - Fix x2goserver extension calls in x2goruncommand. - Add feature name ,,X2GO_PUBLISHED_APPLICATIONS''. - Add new command ,,x2gofeaturelist''. This command can be used by X2Go client applications to retrieve a list of server-side supported X2Go features. - Update date and version number in man pages. - Fix race condition between session.log of x2goagent and x2gocleansessions. The old situation was: in cases that x2goagent was not fast enough with appending the new session state to the session.log file, the x2gocleansessions script marked the session as suspended during the session resuming process. - Wait one second for x2goagent to write to session.log before updating the session state from 'S' to 'R' in the X2Go session database. - Add X2Go server script x2gogetstatus. - Add/enable debugging of x2gocleansessions. - Silence error messages if the agent's session.log file is not accessible (e.g. on NFSv4+Krb5-mounted homes). - Improve concurrent database access with session db backend SQLite. * Remove /etc/x2go/applications on package removal if it is a symlink, keep it, if it is a directory. Remove /etc/x2go (if empty after purge) on package purge. * Bump Debian packaging standards version to 3.9.3. * Use dh_link to symlink X11 directories into /etc/x2go.

The NX (redistributed) code tree has received a fix for the main Makefile. Also a patch for building on Mac OS X 10.5 has been included, plus an X2Go related patch by Oleksandr. On top of that, we have fixed installation of libnx-x11 (Debian package) on 64-bit systems with multi-arch support (i.e. Debian wheezy+sid). X2GoClient and X2Go TCE have received some improvements, too. The shutdown button is now fully implemented witin X2GoClient, the x2gothinshutdown package has been dropped. The TCE also received a new and more colourful boot splash. At this point I would like to explicitly thank Mihai Moldovan for investing his time into X2Go Client development on Mac OS X. Mihai has contributed some great patches to the X2Go Client code and has also taken over the building of the Mac OS X binary of X2Go Client (including nx-libs-lite i.e. nxproxy+libxcomp3). The X2Go project--with Mihai on board--is now able to offer the X2Go Client for current Mac OS X versions again.

Hi, I'm currently writing a systemd service file for the x2goserver. It still does not work and is work in progress, mostly because of x2gocleansession dies with an error message: Here is the service file: ----------> snip <---------- # this is a systemd service file for starting x2goserver [Unit] Description=x2go - remote desktop server After=syslog.target network.target # [Service] # The process to start is x2gocleansession ExecStart=/usr/bin/x2gocleansession # # perhaps some other things have to be done # don't know yet, let's talk to Colin [Install] WantedBy=multi-user.target ----------> snip <---------- And here is the output I get from systemctl: ----------> snip <---------- [root@beteigeuze ~]# systemctl status x2goserver.service x2goserver.service - x2go - remote desktop server Loaded: loaded (/lib/systemd/system/x2goserver.service; disabled) Active: failed (Result: exit-code) since Wed, 04 Apr 2012 11:27:01 +0200; 8s ago Process: 13781 ExecStart=/usr/bin/x2gocleansession (code=exited, status=203/EXEC) CGroup: name=systemd:/system/x2goserver.service ----------> snip <---------- So x2gocleansession dies with an error code 203.

PulseAudio 1.1 for Win32
by Mike Gabriel 03 Apr '12

03 Apr '12

Hi all (esp. Alex), I am currently contracted for fixing PyHoca-GUI on Windows 7. While doing that I found that PulseAudio 1.1 is available as Windows binaries: http://www.freedesktop.org/wiki/Software/PulseAudio/Ports/Windows/Support With PyHoca-GUI this seems to be a great improvement. I guess, that we should ship pulseaudio 1.1 with x2goclient, as well (if not already done, sorry for not being up-to-date here).

NX3.5 speed degradation
by Eugene San 29 Mar '12

29 Mar '12

Hi all, I want to discuss the subject. Story goes like this: About 6 months, while planning upgrade (Ununtu 11.04->11.10) I've noticed severe degradation in speed of NX sessions. At the time I've decided to wait until LTS release, while being sure issue is related to GUI changes in Ubuntu. Recently I've reviewed the situation with 12.04 and found that problem is still there and related to NX and not to GUI changes in Ubuntu. My guess is that surrounding changes in distribution cause NX agent to misbehave. Overall user experience became unusable even on LAN and localhost connections. Now to the details: 1. Screen redraw operations lags heavily even on local links. Instant (sub 0.5sec) on U10.04, up to 5 seconds on U12.04. 2. Constant screen redraws consume much more traffic. Sub 100kbps on U10.04. 10mbps+ on U12.04 (Creating session with WAN quality settings and reconnecting with LAN, lowers bandwidth to sub 1mbps but picture quality suffers) 3. NX4 on U12.04 is faster 3x (in average) than 3.5 on U10.04. 4. NX3.5 on U12.04 is slower 3x then NX3.5 on U10.04 (some tests are x1000 slower!) 5. Hybrid NX3.5<->NX4 is slow with NX3.5 as server and fast with NX4 as server. Some details: * I've evaluated both 32 and 64 bit platforms. * I've compared fresh Ubuntu 10.04 and 12.04. * Both Nomachine NX binaries and X2GO binaries (ppa:x2go/ppa) were tested. * For reference I've performed NX4 and hybrid NX3.5<->NX4 testing. * Tested several usecases: * Desktop with manual operation of terminal, webbrowser and random GUI application. * Rootless UnixBench in graphics mode. (Note in 64bit test caches NX agent!) * Desktop UnixBench in graphics mode. (Note in 64bit test caches NX agent!) * Rootless Xterm with scrolling text (ls -R /) Please provide your feedbacks.

A couple odds and ends questions
by senrabdet＠aol.com 26 Mar '12

26 Mar '12

Hi All: A couple of odds and ends questions about which we're hoping to get some help/clarification: 1) Stored Session Data x2go seems to store a fair amount of session data on both the server and the client in the .x2go folder on both. While these are not large folders, is there a concern that they will mount up over time? Are they limited to a specific number of folders and don't grow beyond that? Is this a "not to worry" sort of thing? 2) Restart Client Session from the Server Is it possible to kill and/or restart a specific client session from the server, presumably from the admin account on the server (we understand that this can be done from the client side)? 3) Force Use of Passwords Is there a way in x2go to force use of log in passwords? We're not sure this is a good idea (or maybe one that has some pluses and some minuses), but can it be accomplished? The only way we've found so far is to encrypt the users /home directory, cancel when the connection fails, and then connect when presented with the x2go screen (usually shown after you log out) that allows us to enter a password. Thanks! Ted

Setting Number of Allowed Connections Per User Account
by senrabdet＠aol.com 26 Mar '12

26 Mar '12

Hi All: We're hoping to set and enable the number of allowed connections/sessions by user and user group in x2go. E.g., we want to limit a user to one session/connection/display at a time: that means from client machine A, if the user A is connected, a connection to his/her account could not be established from client machine B or a second connection couldn't be established from client Machine A. User A, if s/he had second account on the server, however, could start one and only one connection to that second account while running one and only one session to the first account. We think we've seen some posts to this effect involving editing /etc/x2go/x2goserver.conf and /usr/bin/x2gosessionlimit (see http://comments.gmane.org/gmane.linux.terminal-server.x2go.devel/954) We've tried making some of the following types of edits: A) If we edit x2goserver.conf alone, and set either "UserA=1 and/or "UserGroupA=1", we can make multiple connections. When we start another instance of x2go, it shows there is a current session, and when we select "New" in the GUI, a second concurrent session begins. B) If we edit /usr/bin/x2gosessionlimit, and make the following changes and then do a "service x2goserver restart" (not sure if this restart is appropriate or necessary)... Add these lines: if($strlimit <= $scount) { print "LIMIT\n"; exit 0; } Comment out these lines: if($maxlimit <= $scount) { print "$maxlimit\n"; exit 0; } print "$maxlimit\n"; ....and change settings in x2goserver.conf, we got some inconstant results we haven't been able to duplicate, but were along the lines either of a "session limit being exceeded" message even if we had group and/or user limits set to 1 (i.e., we were unable to connect at all), or back to any number of sessions we wanted to start. Can someone suggest a procedure/example of how to do this successfully? Ideally, we'd like the flexibility to limit # of connections/sessions both by user group and individual user. Thanks, Ted

Feedback: Published Applications
by Mike Gabriel 17 Mar '12

17 Mar '12

Hi all, thanks to Stefan we have another puzzle piece for making X2Go the non-plus-ultra solution for people offering Linux-SaaS. There now is a new session mode called ,,Published Applications'', sponsored by Stefan Baur. I have had a quick test look at the functionality, so here is a feedback list, also about other issues that I stumble upon while testing: - I use a dark Qt color theme, with a dark color theme some elements of x2goclient are hardly readable on screen: - session profile cards (right column of the screen= - all buttons (suspend, new, terminate, etc.) - also the button that allows me to launch a published application is not readable on screen with my dark theme - when minimizing x2goclient to systray, I see an icon with transparent background and black contours on a black system tray. Thus, I actually see nothing... - Published applications: Some menu entries have icons, some do not. Where do icons come from? Are they transferred from the server? Or are they used from the client-side file system? - x2goclient is configure _not_ to minimize into the systray. After establishing a published application session I see for buttons in the center of the blue window area of x2goclient. The buttons do not fit in there (they overlap). - Is there a concept for evaluating i18n parts of desktop files? Application links appear in English still. - Alex, whenever we are about to release the new code, we should make a call for translation, so that i18n files are updated with the new version So much from the testing front here... BTW: x2goserver installs and uninstalls/purges fine, I added the code in a rush this lunch time, but it seems to work well.

RDP services
by brian mullan 12 Mar '12

12 Mar '12

John Have you tried the new FreeRDP client <http://www.freerdp.com/> yet? I've not done any extensive testing but it does now support both Microsoft's RemoteFX & RemoteApp services. Its an Apache license app and v1.0 was released and demo'd at the Ubuntu Developer conference in Nov 2011 <http://www.youtube.com/watch?v=Qnh7f36xkRA>. RemoteFX - https://github.com/FreeRDP/FreeRDP/wiki/RemoteFX and RemoteApp services - https://github.com/FreeRDP/FreeRDP/wiki/RemoteApp I've configured Windows 2008 r2 servers on KVM and on AWS EC2, published applications for RemoteApp and then from linux/ubuntu machines run the xfreerdp client and the Windows RemoteApp appears on screen like any other app. I used to have to use seamlessrdp for this but now it just works since the freerdp v1.x release. I'd like to see FreeRDP support in x2go as I understand in the next Ubuntu FreeRDP is replacing rdesktop. Brian ---------- Forwarded message ---------- From: "John A.

Toward the end, you write, "Setting the command to RDP will turn X2Go into an RDP proxy (RDP via NX). RDP will receive a peformance improvement on WAN connections" In our experience, this is true for RDP5 but it significantly degrades the native performance of RDP6 and RDP7. For those wishing to use RDP6 or 7 with Windows XP, TSPlus (www.tsplus.net) makes an XP RDP6/7 client and distributes it freely. I would love to see mimebox included in x2goclient. I know we had planned to write a "multimedia player" to automatically redirect to mimebox similar to the way printing works but have not gotten around to it - still overwhelmed by a large consulting contract completely outside of X2Go :( Thanks again - John

Error/Bug: Arrow keys on keyboard are mismapped
by christoffer krakou 12 Mar '12

12 Mar '12

Hello x2go-team and the rest I'm having a problem on my x2goserver, where the arrow keys seems to be mismatched. For example, the downwards arrow key seems to be mapped as enter instead. None of the arrowkeys work properly. The keymap in question is "Keyboard layout da, keyboard model pc105/da" I'm using ubuntu 11.10 64bit on the server side. x2goversions says: cups-x2go: 3.0.0.4 x2goserver: 3.1.0.0 x2goserver-extensions: 3.1.0.0 Client is the latest stable release, also on Ubuntu 11.10 64 bit. If someone can tell me how to go about it, i would love to do more tests to see excactly how the keys are mismatched, and what keys in particular -- Venlig Hilsen / Best Regards Christoffer Krakou Fleten.net APS

The problem lies within qmake, which "fixifies" the Info.plist path from "Info.plist" to "../Info.plist" and then can't find the find the file anymore, as qmake changes the cwd to the .pro file's directory (thus, in this example, src/). Add both parameters out_d and in_d to MakefileGenerator::fileFixify as Option::output_dir to prevent qmake from "fixing" the file path to a path relative from the (out of source) build dir to the source dir, so that exists() can actually find the file where ever it is, specified by the user and relative to the source dir.

Mihai, Thanks for getting back to me promptly. When your x2go osx client is ready for testing please let me know and I would be happy to validate it. Also for the record, I managed to get sound out of a ubuntu server configured with gnome as the window manager. I was originally trying to use openbox and I have had zero luck with either debian or ubuntu as the server. I have not had a chance to try debian with gnome yet, but I would assume that it would work where openbox did not. Again thanks for an amazing product! Thanks Stephanie

OSX Lion Audio question
by Stephanie Sunshine 10 Mar '12

10 Mar '12

Hi, First off I want to say thank you for an amazing suite. I've never seen a remote desktop so fast or so beautiful. So I'm trying to use my OSX Lion laptop to connect to two different Linux servers. Everything works except audio. So my question is, with the newest x2goclient for OSX does sound work when connecting to a Debian Squeeze or am I just missing something? Thanks Stephanie

Help with shared folder with postgres backend
by Helmer Teles 09 Mar '12

09 Mar '12

Hello, ML Hello Michael. I,ve been strugling with a problem with shared folders under x2go. When there's a problem with a shared folder not unmounting with the postgres backend you can not mount the share anymore. Steps to reproduce. Logon to a x2goserver with a shared folder on the client, next go to that shared folder ( cd ~/media/disk ) and while you are at that folder at the unix server logout from the x2go session. After you logout from x2go the process to ummount will fail because the resource is mounted. After that you can not mount the share anymore because the mountpoint is not removed from the x2go_session mounts table. regards, -- Helmer Teles eM@il : helmer[DOT]teles[at] Google Mail Web Page: http://hteles.wordpress.com

[BUG] Hostname with IPv6 address but no v6 connectivity => SSH connection fail
by Mihai Moldovan 09 Mar '12

09 Mar '12

Hi, just dumping bugs I found to the ML as a reminder for myself (and as a means of gathering confirmations from other people.) Prerequisites: - hostname specified resolves to both an IPv4 and an IPv6 address. - no connectivity via IPv6, but IPv6 configured network interface (half-broken state) Symptoms: - libssh tries to connect via IPv6, but fails - doesn't even try the IPv4 address (which may just work fine) Workaround: - specify IPv4 address as server host Fix: - to do - report to libssh upstream Best regards, Mihai

Issue with sound
by newsgroups.mail2＠stefanbaur.de 08 Mar '12

08 Mar '12

Hi, I'm trying to watch http://www.youtube.com/watch?v=HWqP-ejD6qA on a Debian Squeeze server ("pure" stable) with x2go's stable packages. Client is Windows 7, 32-bit. While it seems to work at first, the browser will lock up after a while and/or sound will simply cease to work. The issue is the same with the current as well as the older clients, and playing with the settings didn't help, either: With some settings, it basically works, but has the issues described above, with others, the session won't start at all or no sound is available. @Mike: I remember you once mentioned that there was a newer version of pulseaudio available that would have to be manually merged with the Windows x2goclient. Is that still the case, or has the newer release been integrated into the Windows x2goclient? -Stefan

cups-x2go problem printing multiple copies from windows terminal server. Fix inside ( i guess )
by Helmer Teles 08 Mar '12

Hello, ML. I've found a bug when i try to print multiple copies from a Windows Terminal Server to x2go-printer if the document has only one page, it only prints one copy. Strangely this does not happen if the document has more than one page. How to reproduce Open a x2go-session, open Freerdp to a windows terminal server, write a new Word Document with only one page. Now print the document with more than 1 copy. Steps to correct it: I've changed the line in /usr/lib/cups/backend/cups-x2go to: # PS2PDF command my $ps2pdf = "/usr/bin/gs -q -dCompatibilityLevel=1.4 -dNOPAUSE -dBATCH - dSAFER -sDEVICE=pdfwrite -sOutputFile=\"%s.pdf\" -dAutoRotatePages=/PageByPage -dAutoFilterColorImages=false -dColorImageFilter=/FlateEncode - dPDFSETTINGS=/printer -dDoNumCopies -c .setpdfwrite -f \"%s\""; FROM: # PS2PDF command my $ps2pdf = "/usr/bin/gs -q -dCompatibilityLevel=1.4 -dNOPAUSE -dBATCH - dSAFER -sDEVICE=pdfwrite -sOutputFile=\"%s.pdf\" -dAutoRotatePages=/PageByPage -dAutoFilterColorImages=false -dColorImageFilter=/FlateEncode - dPDFSETTINGS=/prepress -c .setpdfwrite -f \"%s\""; -- Helmer Teles eM@il : helmer{DOT}teles[AT] google Email Web Page: http://hteles.wordpress.com

X2Go release day: x2goserver, nx-libs, x2goclient, x2gothinclient
by Mike Gabriel 08 Mar '12

08 Mar '12

Dear all, The X2Go Project is proud to announce a couple of new X2Go component releases: - x2goserver (3.1.0.1) - nx-libs incl. x2goagent (3.5.0.12) - x2goclient (3.99.1.1) - x2gothinclient (1.0.1.6) All new packages will be available in our stable repositories (Debian, Ubuntu) within the next 24h. The windows and Mac OS versions of x2goclient will probably be available tomorrow, as well. (PING: @Mihai, @Oleksandr). Sources and binary releases will be downloadable under this URL as soon as they are provided by the packagers. http://code.x2go.org/releases/ The new X2Go Server version adds ~/.x2go_logout script support to the server-side of X2Go and fixes the x2goserver-fmbindings Makefile. The NX (redistributed) code tree has received a fix for the main Makefile. Also a patch for building on Mac OS X 10.5 has been included, plus an X2Go related patch by Oleksandr. On top of that, we have fixed installation of libnx-x11 (Debian package) on 64-bit systems with multi-arch support (i.e. Debian wheezy+sid). X2GoClient and X2Go TCE have received some improvements, too. The shutdown button is now fully implemented witin X2GoClient, the x2gothinshutdown package has been dropped. The TCE also received a new and more colourful boot splash. At this point I would like to explicitly thank Mihai Moldovan for investing his time into X2Go Client development on Mac OS X. Mihai has contributed some great patches to the X2Go Client code and has also taken over the building of the Mac OS X binary of X2Go Client (including nx-libs-lite i.e. nxproxy+libxcomp3). The X2Go project--with Mihai on board--is now able to offer the X2Go Client for current Mac OS X versions again. Thanks for that, Mihai!!! light+love, Mike x2goserver (3.1.0.1-0~x2go1) RELEASE; urgency=low * New upstream version (3.1.0.1): - Provide infrastructure for on-logout script calls. - Do only run session cleanup scripts from within x2goruncommand.

Debian libnx-x11 package for sid 64bit links broken (patch)
by Anthony Callegaro 08 Mar '12

08 Mar '12

Hello there, Since the upgrade to x2go 3.1 I couldn't connect from any clients to my Debian sid amd64 x2goserver. There is no error on the client side just that the session is terminating just after starting. The server is stating that the session started well. /usr/bin/x2gostartagent: successfully started X2Go agent session with ID xxx After long hours of debugging I found out that it was due to some broken links in /usr/lib/nx/X11/Xinerama/ The following solved my issue : rm /usr/lib/nx/X11/Xinerama/libNX_X11.so.6 ln -s /usr/lib/x86_64-linux-gnu/libX11.so.6 /usr/lib/nx/X11/Xinerama/libNX_X11.so.6 rm /usr/lib/nx/X11/Xinerama/libNX_Xext.so.6 ln -s /usr/lib/x86_64-linux-gnu/libXext.so.6 /usr/lib/nx/X11/Xinerama/libNX_Xext.so.6 This is probably due to multiarch, I don't know if there is a simple way to point to the correct lib path in nx-libs.git/debian/libnx-x11.links According to the multiarch documentation [0] : "Any references to files located in /usr/lib from within your packaging, including but not limited to debian/rules, any debian/*.install or debian/*.links files, or maintainer scripts, must be updated by hand for the new locations." The simple attached patch solved the issue for me but will probably break i386 version of the package. Let me know your thoughts.

Windows client using nxproxy 3.4.0

Hi. I've noticed that X2Go client on Linux uses nxproxy 3.5.0 while the Windows client uses 3.4.0. Is there a reason for using the older nxproxy version on Windows?

x2goclient crashing
by Oliver Burger 02 Mar '12

Hi, I have a "little" problem. I built x2goclient, the nx-libs and x2goserver from the SOURCES and it does work, when client and server are running on the same computer. But x2goclient crashes, as soon as it runs on a different one, after showing a popup window, telling me the server reset the connection. Is there any one having an idea, why that is the case? See the client's debug messages here: http://pastebin.com/RTRhRwaZ and the server's log output here: http://pastebin.com/qzEUjkyK Thanks, Oliver

[PATCH] Fix compilation of nxcomp on Mac OS X 10.5.
by Mihai Moldovan 01 Mar '12

01 Mar '12

The Mac OS X 10.5 SDK requires the second argument of FD_ISSET to be writeable, although it does only access the data. Given that we have a const pointer for a const struct, copy and pass that. Note that this is merely a workaround for OS X 10.5, as 10.6 and later define the second argument of FD_ISSET as const struct const *foo, too. It it safe, as data is accessed read-only by FD_ISSET, even on 10.5.

[PATCHv2] Switch to DISPLAY env. var. and UNIX socket connection on OS, X.
by Mihai Moldovan 29 Feb '12

29 Feb '12

Detect the current X11 socket by examining the DISPLAY environment variable, which is set to some UNIX socket path by launchd on each user login. Do a connection test via this UNIX socket. Let nxproxy use the X server via the provided UNIX socket, instead of connecting via TCP. This allows users to shutdown network connections for X11, which is a potential security risk. Even more so, if connection authentication is turned off, which is required for "strange" setups via ssh tunnels, it opens up your machine to any other computer it is reachable by with no authentication.

Clipboard direction?
by newsgroups.mail2＠stefanbaur.de 27 Feb '12

27 Feb '12

Hi list, is there any way to restrict in which direction the clipboard works? NoMachine NX/FreeNX has such an option in its /etc/nxserver/node.conf file: # Enable or disable clipboard: # # client: The content copied on the client can be pasted inside the # NX session. # # server: The content copied inside the NX session can be pasted # on the client. # # both: The copy&paste operations are allowed both between the # client and the NX session and vice-versa. # # none: The copy&paste operations between the client and the NX # session are never allowed. # ENABLE_CLIPBOARD="both" If this functionality isn't available in X2Go, are there plans to add it? -Stefan

[PATCH] Switch to DISPLAY env. var. and UNIX socket connection on OS X.
by Mihai Moldovan 27 Feb '12

27 Feb '12

Detect the current X11 socket by examining the DISPLAY environment variable, which is set to some UNIX socket path by launchd on each user login. Do a connection test via this UNIX socket. Let nxproxy use the X server via the provided UNIX socket, instead of connecting via TCP. This allows users to shutdown network connections for X11, which is a potential security risk. Even more so, if connection authentication is turned off, which is required for "strange" setups via ssh tunnels, it opens up your machine to any other computer it is reachable by with no authentication.

@Mihai: rebuild x2goclient for Mac OS
by Mike Gabriel 26 Feb '12

26 Feb '12

Hi Mihai, could you rebuild x2goclient for Mac OS from the release 3.99.1.0? Either use the tarball provided here: http://code.x2go.org/releases/source/x2goclient Or, alternatively, checkout the tag 3.99.1.0 from x2goclient.git: $ git clone git://code.x2go.org/x2goclient.git $ git checkout 3.99.1.0 I would then provide the updated (and released) .dmg for x2goclient 3.99.1.0 on code.x2go.org.

Hi list, while discussing Mihai's latest work on the OS X client, the following question popped up: Is x2goclient supposed to use Xauthority on all three supported client operating systems (Linux, Windows and OS X), and is it in fact using it if it should*? -Stefan *no woodchuck jokes, please

[SOLVED] Re: [X2Go-User] Call logout script

Approach one (for system-wide plugging-in of custom X2Go extensions): Install the package x2goserver-extensions (normally gets installed by default). Place any script you like (best practice: via a .deb package) into any of the folders: /usr/lib/x2go/extensions/pre-start.d /usr/lib/x2go/extensions/post-resume.d /usr/lib/x2go/extensions/post-suspend.d /usr/lib/x2go/extensions/pre-runcommand.d /usr/lib/x2go/extensions/pre-terminate.d /usr/lib/x2go/extensions/fail-start.d /usr/lib/x2go/extensions/pre-suspend.d /usr/lib/x2go/extensions/fail-runcommand.d /usr/lib/x2go/extensions/fail-suspend.d /usr/lib/x2go/extensions/post-start.d /usr/lib/x2go/extensions/post-runcommand.d /usr/lib/x2go/extensions/fail-resume.d /usr/lib/x2go/extensions/post-terminate.d /usr/lib/x2go/extensions/pre-resume.d /usr/lib/x2go/extensions/fail-terminate.d Approach two (developers, please take note of this commit!): http://code.x2go.org/gitweb?p=x2goserver.git;a=commitdiff;h=a21e0dc286c89e9… > The "/etc/gdm/PostSession/Default" works if we log in directly, so > assume this has something to do with xsession(?) and hope there is a > way in an x2go session where when the user logs out, a script gets > called in the background. The named GDM script is out of our reach when running X2Go sessions. :-(, it is not related to .Xsession calls.

multi monitor support (behind the scenes)
by Heinz-M. Graesing 23 Feb '12

23 Feb '12

Dear List, Since X2Go is an Open Source project, you may use it free of charge. All funds donated to the X2Go project will primarily be used to enhance our project. This could include things such as paying a domain, storage, hardware and costs for representation for the project. All remaining funds will be used to improve our developers work environments, as determined by the project admins. Besides the support trough donation, the main developers are available for paid project enhancements and integration on assignment/contract level. We will always name our sponsors and ordering customers if they want to. So this time we're proud to announce that the already available feature "multi monitor support" was sponsored by ImmobilienScout24 (www.immobilienscout24.de) the leading real estate listing portal in germany. We'll add a page to our internet site to name all supporters and to give some feedback about who is using and supporting X2Go. Again thank you very much! Best Regards, Heinz & Alex
