Did anyone use xmodmap /usr/share/xmodmap/xmodmap.us? Executing that before GNOME finishes loading _will_ lead to the mismatched keyboard layout message.
The correct way to disable SHIFT+Backspace is: xmodmap -e "keycode 22 = BackSpace" -- xgl does not honour keyboard layout https://launchpad.net/bugs/32857 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
