change caps lock as control in .bashrc but no use

Question

I want to make caps lock as control key, so I wrote this setxkbmap -option caps:ctrl_modifier to my bashrc file. The problem is that after I log in the next time or restart the system, nothing happened. Caps lock is still caps lock... So how to change caps lock to control key?

Answer 1

To make that change system wide and persistent, open /etc/default/keyboard for editing, change the line

XKBOPTIONS=""

to

XKBOPTIONS="caps:ctrl_modifier"

and reboot.

Answer 2

~/.bashrcscript just change defaults at terminal session, and it doesn't extend to other areas of your environment. To make this, you could create a script file with this command in it, as:

#!/bin/sh
/usr/bin/setxkbmap -option caps:ctrl_modifier

Then you add it to your sesssion startup manager, as you can see here

Answer 3

I assigned the command to ~/.profile and it works. Now I see that ~/.bashrc script just change defaults at terminal session, people who are fresh to linux like me should notice this too. Thank you guys!
