Multiple sessions fail in 3.0.1.18
by John A. Sullivan III 13 Jul '11

13 Jul '11

Hello, all. In x2goclient 3.0.1-4, one was able to run multiple concurrent sessions even though it was not officially supported and would generate some warnings on the first session when the second was opened. However, it did work. In fact, this very functionality is very important to our first potential large client who wants to create separate environments for each client engagement and has many employees who simultaneously work on multiple clients. This now completely breaks in 3.0.1.18. The first session loses connectivity when the second session is established. Is there any possibility of restoring the previous functionality and even making it officially supported? I use it every day - one desktop into a compilation system on one site and another session to my regular work desktop in the data center. Thanks - John

Display freezes (thinclient) drm:i915_hangcheck_elapsed
by Markus Homburg 12 Jul '11

12 Jul '11

Hi, is there a problem with the i915 graphic chip and the kernel used in the thinclient? After a couple of minutes using the thinclient the display freezes and the just the black screen with the "X-Cursor" remains... dmesg: [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung render error detected, EIR: 0x00000000 [drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5 (awaiting 879 at 878) [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung render error detected, EIR: 0x00000000 Best regards Marcus

Save / change icon x2gothinclient
by Markus Homburg 12 Jul '11

12 Jul '11

Hi there, is there a place where I can store icons for the thinclients? When you start the "normal" client you can access your local hard disk. But in this case I need the data somewhere on the NFS share. If I put the pictures in /home/x2go I can't see them... Best regards Markus

Strange noise on logging screen
by Markus Homburg 11 Jul '11

11 Jul '11

Hi there, I have a little problem with the thin client. After the startup when the logging screen appears I can hear a strange noise. Some kind of white noise. I'm not quite sure but I guess it comes out of the pc speaker. Any idea? Best regards Markus

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
by Stefan Baur 05 Jul '11

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
by Ian Tasker 04 Jul '11

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?
