 <p><a href="http://unix.stackexchange.com/questions/26946/disabling-caps-lock-by-setxkbmap-makes-it-shift-key-in-emacs">This</a> question is probably relevant, basically just use xmodmap to set the keys directly. It worked for me when I had caps lock set to control and I think I was using gnome3 classic (which Cinammon is based on) at the time.</p> <p>On a related note I'd also recommend having a look at <a href="https://github.com/r0adrunner/Space2Ctrl" rel="nofollow">space2ctrl</a>, I found that reaching for caps lock all the time still hurt my fingers.</p>
