I've gotten to where I can launch pyhoca-gui on Ubuntu 10.10 which is running in a chroot environment with Android v2.34 on the $249 Nook Color Tablet I get to the point of a successful connection but then pyhoca-gui dies while logging me in. This log captures first attempt where I forgot to change USER= and HOME= to point to a non-root user ID second attempt was after I'd set both of those then executed pyhoca-gui and tried to connect/login to a remote AWS EC2 x2go server The following is the xsession-errors log contents: = = = = = = = = = = = = = = = = = = root@localhost:~# *more .xsession-errors* Xsession: X session started for root at Wed Jul 6 03:22:11 EDT 2011 X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 109 (X_ChangeHosts) Value in failed request: 0x5 Serial number of failed request: 6 Current serial number in output stream: 8 Xlib: extension "RANDR" missing on display ":1.0". x-session-manager[2108]: WARNING: GSIdleMonitor: IDLETIME counter not found x-session-manager[2108]: WARNING: Could not connect to ConsoleKit: Failed to connect to socket /var/run/dbus/system_bus_socket: Connection refused x-session-manager[2108]: WARNING: Could not connect to ConsoleKit: Failed to connect to socket /var/run/dbus/system_bus_socket: Connection refused GNOME_KEYRING_CONTROL=/tmp/keyring-8ZDnJ7 SSH_AUTH_SOCK=/tmp/keyring-8ZDnJ7/ssh GNOME_KEYRING_PID=2145 GNOME_KEYRING_CONTROL=/tmp/keyring-8ZDnJ7 SSH_AUTH_SOCK=/tmp/keyring-8ZDnJ7/ssh GNOME_KEYRING_CONTROL=/tmp/keyring-8ZDnJ7 SSH_AUTH_SOCK=/tmp/keyring-8ZDnJ7/ssh Xlib: extension "RANDR" missing on display ":1.0".

X2go real life usage
by Martin Oehler 07 Jul '11

07 Jul '11

Hello list, after an update to the current set of packages there are some points that should be (at least in my opinion) discussed. 1) Session Administration At the moment, I can't see a user-friendly replacement of x2go- sessionadministration. This tool is crucial for network usage of x2go since your local administrator needs to be able to reset sessions, connect to an users session and all that stuff. Would the old code compiled against the qt3-libs in Debian Squeeze lead to a working solution? Is there another tool that I wasn't able to find? x2godesktop- sharing is of course not useable if the user session did freeze. Was is the recommended way of stopping an users session (please read topic two before answering, it's not that easy)? 2) Database handling How is the database cleanup of the sqlite3 database /var/lib/x2go/x2go_sessions supposed to work? From my point of view this database is constantly growing. I can't see that old sessions are cleaned up. If a user connects to a LXDE of Debian Squeeze and performs a logout via the menu, his session is still listed inside the database. So this database is constantly growing what is definitely not what one wants. Another problem with this are hanging or crashed sessions. The database gets very quickly inconsistent with the real system state. The user sees a lot of session that are marked active at login but the processes belonging to these sessions do not exist anymore. I found manually cleaning up the database worked but this isn't comfortable at all (i.e. not possible to do for everyone). x2gocleansession is running but doesn't seem to be able to clean up the database (permissions are correct, new sessions are inserted). 3) Smartcard usage This might be a separate topic which leads to a bug, but somehow the timing between x2go und the scdaemon messed up. If a user does a session suspend via smartcard and puts his card in again after the card is available he gets an "invalid card" error message. If one is a bit more patient and waits for 5-6 seconds it works again. Did someone else experience this? I can live with this at the moment. How do others handle these problems in big networks? At the moment I'm really struggling to get to the point where x2go was in terms of usability at "qt3-times" (I know they are gone). Kind regards, Martin Öhler

Re: [X2go-Dev] Windows Client Issue

Hi list, in case the problem is really with the DLLs shipped with the Windows client, I can confirm a similar issue with Windows Server 2008 R2 (which is only available as a 64-bit product) and Nomachine's NX client. What helped there was replacing the files cygwin, cygz, cygpng12 and cygcrypto-0.9.8 with their counterparts from cygwin 1.7. Maybe this is related? Kind Regards Stefan

Windows Client Issue

Hi, I am have been able to setup x2go server very quick on a ubuntu instance. I have a couple of questions though I have been able to connect using windows client version 3.01-4 but not with 3.01-18 I get the following error NXPROXY - Version 3.4.0 Copyright (C) 2001, 2007 NoMachine. See http://www.nomachine.com/ for more information. Info: Proxy running in client mode with pid '7472'. Session: Starting session at 'Wed Jun 29 11:43:32 2011'. Info: Connecting to remote host 'localhost:30010'. Info: Connection to remote proxy 'localhost:30010' established. Connection timeout, aborting I have ports open from 30000 - 300020 on my firewall. Is it possible to limit the port range? As I would only like a small number of ports open. When I try and auto mount a share I get connection reset by peer error is there any additional steps I need to follow to allow file transfers?

X2go for armel on Debian
by Mike Gabriel 04 Jul '11

04 Jul '11

Hi all, I have started building packages for armel architecture on Debian squeeze. As the build process takes tremendously slow I will derive the following limitation for armel packages provided by the X2go project: o only the ,,main'' area will be built (not nightly-builds) o only Debian _squeeze_ packages will be built o only packages needed on the client-side will be built Nearly all packages are already uploaded to packages.x2go.org, apart from x2goclient. This one is currently building which will take some more hours. On ARMEL architectures you then can add this line: http://packages.x2go.org/debian squeeze main and then you should be able to install x2goclient, pyhoca-gui, pyhoca-cli and their dependencies. As I have not such a hardware device at hand, I will depend on feedback with this. Please give your comments and success/failure stories.

X2go backport packages for Debian lenny
by Mike Gabriel 04 Jul '11

04 Jul '11

Hi all, Dick Kniep from the Lindix company in the Netherlands has sponsored the backporting of X2go server-side packages to Debian lenny. As many of you still use lenny on the servers, I persuaded him to make this a contribution to the community. That is: you can use this APT line to install recent X2go packages on Debian lenny: deb http://packages.x2go.org/debian lenny main NOTE: we will not backport the client-side packages. This is only for the X2go servers. Unfortunately there will neither be a backport of x2gokde3bindings, which has not been moved into X2go Git.

sound on x2gothinclient
by Philipp Huebner 04 Jul '11

04 Jul '11

Hi, following the manual for Debian Lenny I have set up a x2gothinclient, but I can't get the sound to work. Any hints how to debug this problem? alsa recognizes the soundcard, it is supportet by the running linux kernel. Is it correct that there is not a single pulseaudio package installed inside the chroot? Regards, -- .''`.

x2goagent / nx-libs 3.5.x.y available for Debian/Ubuntu
by Mike Gabriel 03 Jul '11

03 Jul '11

Hi all, a couple of minutes ago I have built and uploaded x2goagent 3.5.0.2 and NX libs 3.5.0-x to X2go's Debian repos and they have also been built on launchpad.net/~x2go for Ubuntu. You can find the packages in our nightly builds: http://wiki.x2go.org/nightly-built_packages_debian_ubuntu Please test and give feedback. For me a great couple of keyboard issues have vanished with the new x2goagent version. @Reinhard: we should now take a look at the FreeNX patches to incorporate more fixes and improvements. Do you have resources for that?

x2go and android tablets - some progress
by brian mullan 01 Jul '11

01 Jul '11

Pardon me for posting this to the x2go-dev list but I think this is important because of what x2go could do for tablet computers.. I wanted to share this as I think I'm getting close to success. I recently was persuaded by a variety of reviews to buy the $249 (US $) Barnes and Noble Nook Color tablet. short list of features: - 7 inch tablet - OMAP3 processor defaults to 800Mhz but I've overclocked it to 1Ghz (other folks go as high as 1.2Ghz) - WIFI, bluetooth and 1 microUSB port Not to bore you with the details but I rooted the Nook tablet and then updated it to the latest version of Android 2.3.3 (version name = Gingerbread) Then I installed Ubuntu 10.10 successfully on it. First with the LXDI but later switched it to Gnome (just because I'm more at home with Gnome) I added the Ubuntu x2go repository then sudo apt-get update *Now... the interesting part...* Because this is an OMAP3 ARM processor any "sudo apt-get install xxxxxx" where = xxxxxx package name Gets automatically redirected (by Launchpad I guess) to Canonical's ARMEL (ARM repository) to complete the download/install request. Therefore whatever you are requesting needs to have been built/added to that ARM repository. The 'sudo apt-get install x2goclient" did successfully run but so far it only finds the following in the ARMEL repository for x2go: *p python-x2go - python module for X2go client support* *p x2goserver - x2go server daemon scripts* I took some pictures with my cell phone of the Nook Color terminal display above the above & I'll attach them to this but they may be a bit hard to see in any detail. So... from my limited technical knowledge I "think" that its only a matter of time until the rest of the x2go and/or pyhoca-gui x2go clients are supported in the Canonical the ARMEL repository. >From what I understand from the following 2 articles: http://www.thevarguy.com/2011/06/16/canonical-ubuntu-server-embracing-arm-a…<%20http://www.thevarguy.com/2011/06/16/canonical-ubuntu-server-embracing-arm-architectures/> A Canonical engineer at Canonical is/has built a custom 42 core ARM Cluster to in order to do have a a proper build environment and hardware that will allow contributors to submit and build the 20,000+ packages that make up the Linux distribution and to expedite Ubuntu development/porting to ARM architecture(s)... a guess at total build cost was about $4,854. The engineer ordered a custom rack in which to house 21 ARM PandaBoards. 20 of them would be used for package building, with the 21st used as a master board for monitoring and controlling access for each user. Each board is also connected to a 300GB SATAII USB hard drive, giving a total of 6TB of storage in the server<http://www.geek.com/articles/chips/canonical-builds-a-42-core-arm-cluster-s…> . The system works by allocating time on the server when a request is received from a user. The master board checks for a free PandaBoard, reboots that free board, and presents the user with a clean build environment in which to work. Once a build has been completed the board is flagged as free and the process is repeated. This project looks to be ongoing and you can follow its progress over at the dmtechtalk website <http://dmtechtalk.wordpress.com/> where Mandella is regularly posting information and images. The Canonical engineer's got a blog that is posted here with his progress: http://dmtechtalk.wordpress.com/
