As seen via xev, in my user session the CapsLock key (keycode 66) is bound to Multi_key. Whereas in another user (guest) session it is bound to Caps_Lock.
In a terminal I've tried
setxkbmap -option caps:capslock
but nothing changes.
Running showkey on a text console and pressing the CapsLock key gives keycode 58. The default console keymap file /etc/console/boottime.kmap.gz has the following line:
keycode 58 = Caps_Lock
How can I make the CapsLock key be bound to Caps_Lock again?
