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

Re: [X2Go-Dev] [X2Go-User] X2goserver on Ubuntu 10.04.4 server...can't login.

I'm experiencing this error as well. i'll attach a log file from one of my login attempts. The attempt was without sound enabled, though. When sound is enabled, it seems that Pulseaudio gets stuck in a loop of some sort, repeating: Feb 27 08:02:07 fleten-01 pulseaudio[29396]: [pulseaudio] main.c: User-configured server at localhost:30002, refusing to start/autospawn. about once every three seconds. I havent tried to replicate this fully, though.

[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.

[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
