@dino99: I guess this is related to the flash plugin. I only get this error with installed flash plugin. Maybe the new preview releases from adobe fixes this. But I doubt it. Maybe it's not Flash's fault at all.
However, to work around the problem: Do once in terminal: rm -f ~/.xsession-errors* Then hit ALT+F2 and type gnome-session-properties Add a new entry with the command: sh -c 'rm -f ~/.xsession-errors' Add a description like "deletes xsession-errors at login" Close, Log out and log in. You're done. -- Gdk-WARNING **: XID collision, trouble ahead https://bugs.launchpad.net/bugs/401823 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gtk+2.0 in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
