I updated my xubuntu 12.04 xfce 4.8 to xfce 4.10 and now when i switching keyboard layouts activated Scroll Lock. How to disable Scroll Lock when i switched layout? Because the Scroll Lock switches profiles in my mouse. P.S. Sorry for my english.
Problem solved. Solving the problem was: sudo gedit /etc/default/keyboard then removing grp_led:scroll in XKBOPTIONS="grp:alt_shift_toggle,grp_led:scroll" line and then rebot.
