x2gousers is missing?
by Patrick Willam 30 Jul '11

30 Jul '11

Hi all! :-D <blah> Recently i'm taking my time to get my Personal Computers in a more useable and productive state. A very important part of this process/project is getting X2go to run on my systems. </blah> After installing X2go on my main machine (details: see below) i wanted to use it, of course. But when trying to start a session via x2goclient i get no further than while connecting an error dialog appears with this messeage: "Please install this program as SUID x2gouser!" So i thought: maybe there is an issue with the installation process of the packets, and some rights have to be adjusted manually afterwards. But the problem seems to be that a file called "x2gouser" is missing at all!? $> dpkg -L x2goagent x2goclient x2goserver x2goserver-extension \ | grep x2gouser ...gives nothing. Any help/hints on this is very much appreciated. Best wishes, happy hacking and greetings to Treuchtlingen & Kiel! Patrick ps: I `frankensteined´ the "perl-suid" package from "squeeze" using "Depends: perl (>= 5.10.1), libc6 (>= 2.4), libperl5.10 | libperl5.12 | libperl5.14" and installed this manually to get "x2goserver" installed on wheezy/sid. But this will go into another thread. ;-) And now some technical details about my system/intallation... Distribution ============== System is Debian testing(Wheezy)/unstable; mainly testing due to "Apt::Default-Release testing". Other general/verbose info: o SSH-deamon is running (standard config) o respective users have been added to the group "x2gousers" o connection is made to 127.0.0.1:22 o RSA fingerprint is correct and was accepted sources.list ============== /etc/sources.list.d/x2go_org-debian.list # ---------------------------------------------------------------------- # What is x2go? # x2go is an open source terminal server project offering a comprehensive # "server based computing" solution.

x2go Mac OS X Lion 10.7
by Neil Hunt 29 Jul '11

29 Jul '11

Bad news to x2go users who have reliance on a mac client. I upgraded to Lion, which has finally left Rosetta/PowerPC emulation in the dust since Apple has begun moving away from it six years ago, and when I went to connect to my x2go server, I immediately get the error: "You can't open the application nxproxy because PowerPC applications are no longer supported." NoMachine NX 3.5 runs strictly on PowerPC and Rosetta emulation and thus is no longer compatible with Lion. NX4 runs on Intel natively and will run on 10.7 Lion. There is the OpenNX client for Mac which I've tested on Lion and connects to my FreeNX server no problem. So the nxproxy library must somewhere be ported to Intel-based Lion architecture? Please advise, we have quite a few users who use x2go mac client and I need to have a support plan for Lion migrations. Thanks, Neil

x2goclient version bumping -> 3.99.0.0
by Mike Gabriel 22 Jul '11

22 Jul '11

Hi devs, today I had a chat with Alex about x2goclient, the versioning, the next major version (Baikal) of x2goclient, etc. o we have bumped the version to 3.99.0.0 in Git o the next major stable release will be 4.0.0.0 (x2goclient/Baikal) o Oleksandr will build a Windows x2goclient with that same version number Packages for Debian are building currently, they will enter the nightly builds repos as well as the ,,main'' repos. Please go ahead and test these new versions, please. Report issues to the x2go-dev mailing list, so that we get as many issues fixed before calling the thing 4.0.0.0.

core dev-team testing x2goclient during next week
by Mike Gabriel 22 Jul '11

22 Jul '11

Hi all, thanks to everyone (esp. to John) for taking such a meticulous look at the latest x2goclient 3.99.0.0 (Win32 version). There obviously seem to be quite some open issues that we have to cross-check on our own development/testing systems. Alex (the core developer of x2goclient) will do that ASAP, we hope to come up with some feedback, patches, comments by the end of next week. If that gets delayed, I will let you know about the delay and come up with another timeline. Unfortunately, as X2go is not a commercial project, this cannot be any quicker. We apologize for this!!! If there are people out there you can read/write C code, please feel free to clone git://code.x2go.org/x2goclient.git and cross-read the code. Some other problems, however, may arise from x2goagent, as well. So you might use git://code.x2go.org/x2goagent.git for lecture as well...

RDP packing
by John A. Sullivan III 21 Jul '11

21 Jul '11

Hello, all. We are still trying to address the very poor performance of rdesktop sessions transmitted over NX - much slower than native RDP although we were expecting it to be much faster. In reading the NX documentation, we saw that they have a packing algorithm especially for RDP. However, whenever we enable this packing algorithm, the session aborts. Has anyone successfully used it? How do we troubleshoot this issue? Thanks - John

John Are you sure there's nothing wacky going on with your Windows systems? I have been following your posts to the SPICE alias and maybe my memory is foggy but weren't you having some of the delays etc with SPICE as well when running the client?

Fairly severe problems for our Windows users
by John A. Sullivan III 20 Jul '11

20 Jul '11

Hello, all. Internally, we are almost exclusively a Linux desktop shop and our experiences with X2Go are simply amazing. We architected a very powerful back end and the applications just explode on the screen even though all of them are across WAN connections. The X2Go performance is generally much better than our local systems. However, most of our initial clients are Windows users (for the X2Go client) and they are continually complaining about bad performance to the point we have stopped major new rollouts. We bit the bullet and installed Windows on our local systems and . . . they are right. The Windows client performance is much worse. I'll outline what I have seen but I have seen it consistently in 3.0.1-4, 3.0.1.18 with Xming, and 3.0.1.18 with vcxsrv. I also tried Pyhoca (0.7) but it kept mangling my authentication so I cannot report on it. There are two different types of problems. The first is generally laggard response. Typing, screen refreshes, scrolling - everything is generally slower. I would guess this is simply because we must shim a local X server between NX and GDI and it may simply be the way life is. I was hoping it would not be so noticeable. The second problem is far worse, however. It seems that sometimes screen painting of the active application stalls. Again, we've seen this on all three platforms described above. We most often see this in Iceweasel (we are using Debian X2Go Servers). Users will have multiple tabs open and will switch from one or the other or from one widget in an Ajax application to another and nothing happens for literally a minute or two. They can switch to other applications and work there so this is not simply packet loss on the line. The application itself does not update the screen. After a minute or two, everything they typed or the results or their mouse clicks all appear. This is the killer issue right along with the disappearing mouse. We cannot have our users wait for a minute or two every few minutes while they are working on their applications. Again, they can move to a different application and work but their previously active application, usually Iceweasel, just pauses and then catches all events up a minute or so later. Any suggestions on how to troubleshoot and fix this? Thanks - John

My current test environment is 32 bit Windows XP. We have another user testing 64 bit Windows 7. Most of the complaining users are 32 bit Windows XP. The disappearing mouse pointer is an Xming bug. Moving to vcxsrv will solve that. I think 3.0.1.14 was the first to support that but I'm not sure. We are also using an old X2Go Server - 3.0.1-5 I believe. Thanks - John
