Bug#343: Invisible UI components when compositing enabled
by Wil 19 Nov '13

19 Nov '13

Package: x2goclient 4.0.1.1-0~427~ubuntu12.04.1 Version: 4.0.1.1 (from x2go stable) Ubuntu 12.04.2 LTS 3.2.0-51-generic-pae #77-Ubuntu SMP Wed Jul 24 20:40:32 UTC 2013 i686 Qt: 4.8.1 KDE Development Platform: 4.8.5 (4.8.5) KDE Daemon: $Id$ When the compositing extension is enabled some UI elements seem to completely disappear. For example using the oxygen theme in kde the menus are no longer visible (likewise oxygen-gtk for gtk+ apps). Also the scroll bar overlay control for the thin gtk+ scrollbars does not appear to show. The default panel in kde is also invisible. I'm not sure how much work it would be to fix this but with compositing turned off there are often thick black borders around UI elements that should be composited. This even affects applications like Eclipse as well as the window / display manager UI etc.

Bug#342: Seamless / rootless apps don't resize in KDE/Kwin
by Wil 17 Nov '13

17 Nov '13

Package: x2goclient 4.0.1.1-0~427~ubuntu12.04.1 Version: 4.0.1.1 (from x2go stable) Ubuntu 12.04.2 LTS 3.2.0-51-generic-pae #77-Ubuntu SMP Wed Jul 24 20:40:32 UTC 2013 i686 Qt: 4.8.1 KDE Development Platform: 4.8.5 (4.8.5) KDE Daemon: $Id$ When trying to resize a rootless window in kde with kwin window manager the resize appears blocked. It's possible to resize the window a tiny bit and then it stops resizing (the resize cursor is still showing though). If all the affects and compositing are turned off occasionally it will start working. It seems worse after the application has just been started and when the resizing kicks in it does seem to keep working. The problem seems to go away if metacity is chosen as the window manager (obviously this is less than ideal as a lot of kde functionality is disabled and metacity themes often feature very fiddly resize borders).

wmctrl problems
by Jean-Francois Dagenais 14 Nov '13

14 Nov '13

Hi all, Running x2go server on ubuntu (12.04), and my terminal is a mac running XQuartz (with quartz-wm) and the Qt x2go client. I used the Published apps rootless and spawn a few windows from the server. Things run pretty smoothly and Im happy with the performance. The thing that hurts is related to window management. Heres a relevant output: $ echo $DISPLAY :50 $ wmctrl -l Cannot get client list properties. (_NET_CLIENT_LIST or _WIN_CLIENT_LIST) $ wmctrl -m Cannot get window manager info properties. (_NET_SUPPORTING_WM_CHECK or _WIN_SUPPORTING_WM_CHECK) Whereas if I run the same commands natively on the mac, XQuartz responds correctly to wmctrl. So the problem affects pretty much all tools related to window management I tried. I am no X11 expert, but I am a developer and very familiar with linux systems. Right now I just need a few pointers, any thoughts? Thanks in advance! /jfd

Re: [X2Go-Dev] Bug#338: gnome no longer working in Ubuntu 13.10
by brian mullan 14 Nov '13

14 Nov '13

With Ubuntu 13.10... *gnome-session-fallback * has been replaced with: *gnome-session-flashback* Gnome Flashback is a session for Gnome 3 which was initially called "Gnome Fallback", and shipped as a stand-alone session in Debian and Ubuntu. It provides a similar user experience to the Gnome 2.x series sessions. It consists of the following components: - GnomePanel - Metacity - GnomeApplets The first release was on 2013-09-25, included in gnome-panel 3.8.0. This is the first release that ships a session descriptor and wrapper script for the "Gnome Flashback" session. This is similar to the standalone fallback session previously shipped in Debian / Ubuntu. As integration with the rest of the Gnome stack has suffered somewhat, this is mainly aimed at distributions that still want to support a metacity / gnome-panel based desktop (e.g. for LTSP installations). Some integration work may be necessary - for example, nautilus 3.8 no longer draws the desktop background icons. Brian

upcoming changes for shadow session names in X2Go Server 4.1.x.y
by Mike Gabriel 13 Nov '13

13 Nov '13

Hi all, I have today made a change to the naming of desktop sharing / shadow sessions in X2Go. Earlier, I already added a script x2golistshadowsessions. Yesterday, I realized that it works for the wrong user. It works for the user who is sharing his/her desktop session. But it actually was intended for the user who requests desktop sharing. Note that x2golistshadowsessions is only used from PyHoca-GUI's desktop sharing feature. The x2golistshadowsessions command is not available in x2goserver below version 4.1.0.0. Today then, I wrote a patch for X2Go Server (x2goserver.git, master branch) that changes the session names of desktop sharing sessions. Until now: ---------- <shadowed-user>-<dpl>-<tstamp>_stS0XSHAD<shadow-user>XSHADPP<shadow-display>_dp<depth> From now on: ------------ <shadow-requesting-user>-<dpl>-<tstamp>_stS0XSHAD<shadow-user>XSHADPP<shadowed-display>_dp<depth> With this change x2golistshadowsessions shows shadow sessions to the user who requested the shadow session. This fixes crashing desktop sharing sessions in PyHoca-GUI, btw. It also transparently works with X2Go Client. Feedback? Comments?

SupeReNicer support for X2Go Server 4.1.0.0-preview
by Mike Gabriel 13 Nov '13

13 Nov '13

Hi all, the 4.1.0.0-preview (x2goserver.git master) just received a code patch from Guangzhou Nianguan Electronics Technology Co.Ltd, an open source company in Asia that plans to use X2Go for school setups in areas where electricity is a rare resource. They plan to build cost-effective and energy-effective embedded thin clients running X2Go. The patch we received adds a feature to X2Go Server called SupeReNicer [1] and it is a tool that hooks into x2gocleansessions. It renices suspended sessions to nice level 19 and renices them again to nice level 0 once they change there status from suspended to running. See the new x2goserver.conf template for configuration hints [2]. Happy testing!

Hi, not sure if everyone is reading slashdot, so http://slashdot.org/stories/gateone might be worth a visit. This fellow coded a SSH terminal emulator in HTML5/JavaScript and is adding X11 support as well. -Stefan
