I'm on latest debian testing with i3wm on two different laptops.
Linux mango 4.19.0-2-amd64 #1 SMP Debian 4.19.16-1
When I press LeftAlt + x I get "ø". And other special chars with other keys.
I want to disable it, as I assume it is what is stopping me from using Alt-x in emacs, which should be bound to "execute-extended-command" by default. But it only says "ø is undefined".
It does not seem to be the compose key though, as running:
setxkbmap -model pc105 -option compose:caps
Does not affect Alt-x's behavior. Where is this configured?
Update to clarify:
I'm using uxterm and terminal emacs "-nw". I added
XTerm.vt100.metaSendsEscape: true to .Xdefaults and .Xresources but it had no effect.
Here is the output of
xkbcomp $DISPLAY -
