X2go keyboard layout
by Raphaël RIGNIER 13 Sep '12

13 Sep '12

Hello, I'm using the stable release of x2goserver from ppa for Lucid LynX distribution. Connection via last Windows x2goclient is correct but my keyboard is messy. if from the client I check no keyboard ovverride, then my french Altgr Key isn't working as expected. If I force french keyboard, Altgr is working. Anyway, the NumPad isn't working at all. Is there any solution ? Thank oui.

Answering a blog post: no X2Go Client for Android yet
by Mike Gabriel 12 Sep '12

12 Sep '12

Hi Cyprian, on blog.x2go.org you asked if there is an X2Go Client for Android. I am afraid, there currently is not. Anyone interested in the development (there was a guy who planned to do it) is welcome on the developers' team. (Anyone else who wants to contribute is welcome, as well). For further questions on X2Go, please use email and subscribe to: http://lists.berlios.de/mailman/listinfo/x2go-user After that you can post to x2go-user(a)lists.berlios.de Greets, Mike -- DAS-NETZWERKTEAM mike gabriel, rothenstein 5, 24214 neudorf-bornstein fon: +49 (1520) 1976 148 GnuPG Key ID 0x25771B31 mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

Two new features in X2Go Client
by Oleksandr Shneyder 06 Sep '12

06 Sep '12

Hallo list, I'm very glad to introduce two new features in X2Go Client. 1. Direct RDP connection to Windows Terminal Server. This feature was sponsored from Mirco Rohloff from "Rohloff AG" - http://www.rohloff.de With this feature you can open direct RDP connection using installed on the client system RDP client program without X2Go proxy. It could be useful in mixed environments with both Linux and Windows TS. This feature is only available for Linux client. To use it, choose Session type "Connect to Windows terminal server" in Session preferences. You should also check "Direct RDP Connection". After that you can configure additional setting in tab "Settings". In this tab you can choose display resolution, RDP client to use and also specify additional command line parameters. I suggest to use direct RDP connections only over LAN or VPN connections. Over Internet using X2Go proxy is faster and securer. You can install X2Go Client-3.99.3.0 which contain this feature from our repository "heuler" 2. X2Go client with old (0.9.6) Pulseaudio. This feature was sponsored from Stefan Baur from "BAUR-ITCS UG" - http://office.stefanbaur.de/ This is an alternative "interims" X2Go Client for Windows which includes an obsolete version of Pulseaudio. You can try this version if you have problems with sound in Flash. You can download a Windows binary from here: http://code.x2go.org/releases/binary-win32/x2goclient/with-old-pulseaudio-0… Regards, Alex -- Oleksandr Shneyder Dipl. Informatik X2go Core Developer Team email: oleksandr.shneyder(a)obviously-nice.de web: www.obviously-nice.de --> X2go - everywhere@home
