Emacs and chord translation

Question

I'm having some issues with emacs, in particular when using SLIME. It's not reading the slime-eval-defun command (bound to C-M-x) but will read C-M-S-x... same issue with the indent function C-X-q, I have to add a shift to make it work.

When looking into the key bindings I get this

C-M-x (translated from C-M-S-x) runs the command slime-eval-defun,
which is an interactive Lisp function in `slime.el'.

So it picks up C-M-S-x and assumes that I want C-M-x, which is true, but I'm not getting why it's not picking up C-M-x in the first place!

I'm running emacs on Arch as a guest OS, host OS is OS X.

Answer 1

So I found out that the KDE default shortcut for activating clipboard actions is C-M-x. I removed that and the SLIME shortcut works now.
