Re: [X2go-dev] x2go python scripts
by Dick Kniep 30 Oct '10

30 Oct '10

Hi List, We (Mike Gabriel and myself) are currently developing a new Python based (gui)client. For me the main reason was the instability of XMing, the X-server that is incorporated in the current X2go client. The new Python client will have a configurable X-server. So if you want to use Cygwin/X it is OK, if you want to use Xming it is OK, and if you want to use a commercial X-server that should work also. We hope to have a working copy at the end of next week. Off course that will be Beta, but should be usable nevertheless and should have all features included. After that testing should be done on Windows and Mac. I hope we can start packaging the whole thing after next week. (I am an incurable optimist!) Cheers Dick Kniep -----Oorspronkelijk bericht----- Van: John A.

x2gosessionlimit
by Gerry Reno 29 Oct '10

29 Oct '10

Hi list, I have been trying to set x2gosessionlimit to limit the number of active sessions. So as a simple test I set the x2gousers group setting to 2 and then started creating sessions for users that were part of the x2gousers group. It did not seem to limit the number of sessions that I could create. So is this not the correct usage? I read John's post from last summer about x2gosessionlimit but there was no response to his post. Can anyone shed some light on this? Regards, Gerry

open source Java based x-server for windows
by brian mullan 27 Oct '10

They could have chosen a better name but here's the description. But it too sounds like it would need work because it mentions "WeirdX supports core protocols of X11R6.3 partially." Open Source - WeirdX <http://www.jcraft.com/weirdx/> written in Java - WeirdX handles x protocols directly. - WeirdX supports core protocols of X11R6.3 partially. - WeirdX is implemented with JDK 1.1. - WeirdX runs as an application/applet. - WeirdX supports *Rootless* mode. - WeirdX runs as a TrueType font X Server if your JVM supports TrueType fonts. - WeirdX supports the three mouse button emulation. - WeirdX supports copy/paste operations between the native window system and x clients via CUT_BUFFER0. - WeirdX supports 1bpp, 8bpp and 16bpp mode. - WeirdX supports multibyte characters; Japanese, Korean and Chinese characters. - WeirdX allows you to get secure X accesses in pure Java by using JSch<http://www.jcraft.com/jsch/> . - JRexec <http://www.jcraft.com/jrexec/> is included. - WeirdX supports XDMCP. - WeirdX supports dxpc(Differential X Protocol Compressor) with the assistance of JDxpc <http://www.jcraft.com/jdxpc/>. - WeirdX includes hacks for the alpha transparency. - WeirdX supports EsounD <http://www.tux.org/%7Ericdude/EsounD.html>compatible applications. - WeirdX includes the XJS Extension written by Christian Werner<http://home.t-online.de/home/Christian.Werner/> . - WeirdX is distributed under GNU GPL.

hi Gerry, Please add also wxPython 2.8 as a requirement. For me the main reason to develop this is that the windows client is not stable if used with a single application. The problem is with XMing, try to run a single application and move the mouse fast around if running under Windows 7 and it crashes. Furthermore I think we can make some enhancements for the gui, (operating from the Taskbar, automatic minimizing of the gui etc.) and as python and wxpython are crossplatform we can run the same code on mac, Linux and MS-Windows. So we would have only a single code base to maintain, which would be good for the quality of the total solution. We are working very hard on this development, but it will take some time before it is all stable. Also the gui will be GPL, so please be patient, we will keep you posted. -----Oorspronkelijk bericht----- Van: Gerry Reno <greno(a)verizon.net> Verzonden: di 26-10-10 00:09:55 Aan: Mike Gabriel <m.gabriel(a)das-netzwerkteam.de>; CC: x2go-dev(a)lists.berlios.de; Onderwerp: Re: [X2go-dev] x2go python scripts > On 10/25/2010 05:36 PM, Mike Gabriel wrote: > > Hi Gerry, > > > > thanks for asking your questions. > > > > On Mo 25 Okt 2010 17:58:56 CEST Gerry Reno wrote: > > > >> There appear to be a number of efforts involving developing python > >> scripts for x2go. > >> > >> What are the status of these python efforts? > >> Did Jörg abandon his effort? > > > > Yes, Jörgs approach was initially licensed as GPL, but his contractor > > refused to grant publication under an open license. > > > >> Mike, you mentioned the you were redeveloping Jörg's scripts. > > > > Yes, I have rewritten Jörgs ideas and expanded the possibilities: > > > > + pulse audio support > > + local folder sharing > > + printing (work in progress) > > > >> Is that effort finished? > > > > No, that will probably take a great little while more.

Top numlock keys do not work
by John A. Sullivan III 27 Oct '10

27 Oct '10

Hello, all. We are aware that we must be careful about Num lock and CAPS lock because toggling them in the physical desktop does not toggle them in the virtual desktop but toggling them in the virtual desktop toggles them in both - thus they can easily get out of sync. However, one of our clients reported something a bit nastier and I have confirmed it on my setup. When the num lock is toggled off in the virtual desktop, the /*- keys work properly. When num lock is toggled on, those top three keys cease to work. That is extremely awkward for those doing accounting work or heavy date entry (the client's bookkeeper reported it!). Is this a misconfiguration on our part or is it a bug? Thanks - John

xming and x2go
by brian mullan 27 Oct '10

27 Oct '10

Heinz & Gerry It would seem logical that an open-xming project would be needed by more than just x2go community.

X2GO Ubuntu 10.10 on Linux and Mac clients "d" key
by Neil W. Hunt 26 Oct '10

26 Oct '10

Hello, I am testing out X2go with Ubuntu 10.10. Everything works great and we are leaning towards rolling this out to our entire development organization if we can solve a few outstanding issues. Right now, the biggest one we're facing is that whenever I type 'd' it hides all open applications and shows my desktop. Every other key seems to work just fine, as does sessions suspend/resume, audio, performance, etc. but obviously this is still unusable to us with the 'd' key being unavailable. I have tested this on the Linux, Mac, and Windows X2go clients and this is only the behavior on the Linux and Mac clients, not on the Windows client - the 'd' key works fine on Windows x2go client. Any thoughts? FWIW, On Ubuntu 9.10 using x2go, I don't have this issue with Mac/Linux clients. However, we don't want to confine ourselves to 9.10 by choosing x2go.

x2go python scripts
by Gerry Reno 26 Oct '10

26 Oct '10

There appear to be a number of efforts involving developing python scripts for x2go. What are the status of these python efforts? Did Jörg abandon his effort? Mike, you mentioned the you were redeveloping Jörg's scripts. Is that effort finished? And what ssh connection approach is being taken with python scripts? Multiple ssh connections the same as the perl scripts? Or establish and reuse a single ssh connection? And what is the minimum python level necessary to run these python scripts? 2.3, 2.4, 2.5, 2.6? Just trying to gauge the requirements, features and maturity of the python efforts. Regards, Gerry

phantom sessions
