x2go client for Ubuntu ARM?
by Jo-Erlend Schinstad 23 Sep '10

23 Sep '10

I'm currently working on the IGEPv2 board, and it's mostly working. I'd really like to see how well it works with x2go. Is there any packages for Ubuntu ARM? Thanks, Jo-Erlend Schinstad

I've tried nearly all of the leading remote desktop technologies that I could find. Remote Video is hard to improve on any of them without taking a different approach that frame buffer forwarding. So NoMachine's NX, Citrix's remote desktop technology etc all are limited by bandwidth constraints of trying to push full motion video frame buffers across a WAN link.. no matter how good the compression. Which by the way also affects video quality because of delay. There are solutions out there that are trying to address this in a different architectural way such as the Spice client & server architecture which does the video processing at the client and more or less sends gui control cmds over the net. There is also PCoIP (PC over IP) which works very well at full motion video and also 3D video BUT it requires hardware installed at the server side and also a PCoIP card at the Client side... so its not cheap. I think there are 2 other things that should impact the performance current NX related solutions: 1) I recently read that several NX solution vendors are now using *libjpeg-turbo *instead of the older libjpeg. *http://libjpeg-turbo.virtualgl.org/* * It's a high-speed version of libjpeg based on libjpeg/SIMD but with additional optimizations and support for 64-bit platforms (and neatly* * packaged into an SDK that can install on most types of x86/x86-64 systems.) It's 2-4x faster than libjpeg and GPL-compatible, so I would* * imagine that NX related remote desktop solutions like x2go, FreeNX and NX from NoMachine itself woul all benefit from it performance-wise.* *NOTE: when I first tried libjpeg-turbo I installed it only on the client and I didn't seem much if any change. However I recently learned that actually has to be innstalled on BOTH server and client to see the performance benefit but in a recent test I saw the results of increased performance 180%. BUT - I'd still recommend running Browser based video like YouTube off of the local Client machine instead of over the Internet from a remote desktop. * *2) HTML 5 with its enhanced support for multimedia (video & audio)* * Brian * > > Am Mittwoch, den 22.09.2010, 21:56 -0600 schrieb Dimitris Anogiatis: > > Dear List, > > > > > > Does anyone know of any advantages from installing a hardware ssh (or > > crypto) accelleration device on a server machine running x2go? > > For example I've tried to tweak my SSH server but despite some > > improvements in responsiveness video playback (I tried a youtube > > video) is still choppy. > > > > > > Would a device like that help or does x2go's design not allow it to > > benefit from such an enhancement? > > > > > > I'm using my x2go client from a remote location using wifi and not in > > a LAN. > > > > > > Regards, > > Dimitris > > _______________________________________________ > > X2go-dev mailing list > > X2go-dev(a)lists.berlios.de > > https://lists.berlios.de/mailman/listinfo/x2go-dev > > > **************************************** >

Installing on Ubuntu Lucid/KDE4?
by Matthew Macdonald-Wallace 23 Sep '10

23 Sep '10

Hi all, I've been setting up a thin-client solution based upon x2go and I'm interested in seeing if it will work with KDE4 on Ubuntu Lucid/Maverick. The issue I've run into is when installing the x2goldapadmin tools the installation borks out stating that kcontrol is not available. Does anyone know if packages are available for the above combination? Thanks, Matt

GPL violations
by Jörg Sawatzki 23 Sep '10

23 Sep '10

Hey list, I just got an email back from Heinz - a private mail! You know that I have been discussing about the plugin and sources with him and Alex on this list for a couple of months now. Other people have asked as well where the sources for the plugin are. Obviously they think that I cannot read C++ code and sent me the link to the plugin.cpp source (http://x2go.obviously-nice.de/mozplugin/) again - in the hope that I believe them. But unfortunately I had a look into the code (trying to build it) and saw that it executes a binary: an extended version of x2goclient with heaps of new command line options. Asking for the source (which is your and my right according to GPL) I got one of these famous excuses saying "oh, we are in the process of changing to QTBrowserPlugin" and so on. In short: 99% of x2goplugin's sources are not published - this affects (modified and not modified) third-party components as well. Everybody who publically distrubtes GPL software in binary form and does NOT provide a link to the sources violates the license. The GPL doesn't say "if you have time and the weather is nice you can publish the sources if you want to". Therefore I would not recommend anybody to use the plugin in a production environment and integrate it into any project! It will be you who will get into court if one of your customers enforces his GPL rights and you have distributed it in your project. Just to let you know: I feel a bit fooled with all the excuses and that they try to somehow get around legal requirements by sending me some stuff that's only a 7.5K file wrapping around the actual component. In my opinion, the way they deal with community input/ideas/contributions is ignorance. Nothing of the critics and proposals was taken seriously. We still don't have a GIT repo - and that would take them 5 minutes or less! But that's alright - we don't have to have git. But we HAVE to follow legal requirements in the GPL. And not next year, but NOW! I spent a lot of time and energy into this and the result: I am maintaining my own python code externally now, because they don't let me contirubte! And the worst result: I am frustrated as hell, that I spend months waiting and writing dozens of mails to enforce my rights that I have by law. After all, I'd just like to inform all of you, that I am going to report this to gpl-violations.org as after explaining it again and again I still see no change. I'll inform NoMachine as well and advise them to enforce their legal rights as well - it is their code as well! I am sorry for bothering you with this, but I think it is important to draw things like this into plubic attention Jörg

Joerg You just said in one of your responses... "*I am asking for the source for a month or two*".. Okay... - Alex was on vacation a month ago. - Heinz is on vacation now - each was 1 month off. I know it was thoughtless of them to take vacations and I'm sorry their responsiveness didn't meet your needs. You DO have choices... 1. wait until the new x2go is actually released and then see if you can get what you want 2. go elsewhere and find another solution such as: - NoMachine's NX v4.0 is do out soon - FreeNX - NeatX - or look into the Spice client & server software from Red Hat. Thanks for your comments and opinions but I'm not sure the discussion is very productive at this point and perhaps the forum could go back to answering other questions?

Plugin building
by Jörg Sawatzki 22 Sep '10

22 Sep '10

Hi Heinz, Alex and list, as there are lots of questions and wishes arising on this list and by my customers, I'd like to build my own version of x2goplugin and x2goclient to be able to play around and implement new things. As you told me some days ago, the plugin source is here: http://x2go.obviously-nice.de/mozplug/ That is indeed true - but where's the rest of it? As far as I can tell from the code, it starts an instance of x2goclient with some "secret" command line options. Where is that modified x2goclient's source? It's not the 3.01 x2goclient that is floating around around somewhere in x2go.obviously-nice.de/deb, is it? Thanks, Jörg

Joerg I agree with John in his view of Hienz and Alex. They are good folks BUT everyone has to remember they are ONLY 2 people ! They have a separate life where they have to earn money to support themselves & families too. x2go is something they have dedicated themselves to because it aids them in their other income related activities. There's an old saying: Nothings impossible for those that don't do the work. Given that Heinz and Alex have been working for the past year to create this new release of x2go ... again while working on their day jobs ... oh, and while building the new x2go wiki etc. Now that they are in what is hoped to be the final stages and frankly I'd rather they focus on that and worry about where to post the source code when they have some breathing space. Give them a break is my vote. Brian Mullan ------------------------------ > > Message: 3 > Date: Wed, 22 Sep 2010 14:51:42 -0400 > From: "John A.

Resume specific session with x2goplugin
by contact＠gmli.fr 22 Sep '10

22 Sep '10

Hi, (first of all, thanks for your help Heinz and Sven) I would like to know if it's possible to resume a specific session with the plugin ? The goal is to list sessions (with x2golistsessions) on the server, and paste the session id in the x2go.server file in order to resume it. I don't want to use the resuming form showed by the plugin (my users are confused with it). I'm making a webapp, and I would list sessions in a web page, and make it possible to resume paused sessions just by clicking on a link. Thanks in advance ! Regards, Guillaume

headless client with pyx2go
by Dick Kniep 22 Sep '10

22 Sep '10

Hi list, We want to develop a headless client in python using pyx2go. The application should have the following features: 1. All parameters except for the password should come from a profile stored in the users home directory 2. The user should have the possibility to enter the password, the username and the server, where the username and the server should be retrieved from the profile 3. The client should support clientside printing as the x2go client 4. The home directory (or another directory) on the clientside should be mounted with fuse on the serverside 5. The client should start XMing with all appropriate parameters 6. It should be possible to start an application from the server side by starting a file. So if a file called test.doc exists and that file is started, MS-Word should start. 7. The profile should be maintained by a separate program (nice gui application) We've got the demo.py running. However when it ends, the session is terminated correctly, but a thread remains active. Probably the thread should be joined with the mainprogram. Could anyone help us with documentation on the use of fuse and the way commands are passed from client to server vice-versa? Dick Kniep Lindix BV tel. 036-5215580 mob. 06-50991858
