Ok here some more informations. I discovered some strange behaviour about gnome-session-save. YOu can see in the gutsy generated session file that xfwm4 is set as default manager with no reason. However for an odd reason the desktop > gnome > application > window_manager > current Gcong key was set to /usr/bin/xfwm4 which could explain the error.
Anyway this clearly demonstrate that the gnome-session-save command is not looking for the WM your are using but is looking to the Gconf key which like i shown can be wrong. Please try to reproduce this on your computer, set the desktop > gnome > application > window_manager > current Gconf key to something else than your current WM and check that gnome-session-save will take in consideration your Gconf key and not your current WM. Then change your WM and check that the Gconf key (like i guess) is not updated. I'm pretty sure to have located the problem now, thanks to anyone who can confirm this. -- gnome-session-save scew up session file https://bugs.launchpad.net/bugs/157780 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
