I never use the Caps Lock button. Never. The only time I "use" it is when I accidently press it and start typing things in UPPERCASE. To disable it in Linux all you have to do is enter this on the command line:

$ xmodmap -e "remove lock = Caps_Lock"

To set this permanently, just stick the above line in your ~/.bashrc file (or /etc/bash.bashrc if you're root) so that it looks something like this:

if [ "$PS1" ]; then
   # Disables the bloody CapsLock button
   xmodmap -e "remove lock = Caps_Lock"

I love it! After applying your line in my .bashrc, I went looking for a way to disable the Num Lock key, wanting it to always be in numeric mode. I could not find any way to do it, but I did discover that you can do the same thing by using a line something like..

xmodmap -e "keycode 79 = KP_7 KP_7"

This doesn't disable the Num_Lock, but it doesn't matter.

Use "xmodmap -pke" first, to check which keycodes are relevant.

Thank you for this tip. I however wanted to let caps lock do the same as shift. This did the trick for me:
xmodmap -e "remove lock = Caps_Lock"
xmodmap -e "add shift = Caps_Lock"

I've linked to this page from my homepage:

Just G.R.E.A.T. !
... As I used to remove the caps lock keys on my keyboards !
I can now restaure them to their original places !

Good work!

Alternatively, for the vi/vim users, turn your Caps Lock into an Escape key. Now you can switch modes without any stretching off the home row.

Add the following to ~/.Xmodmap

remove Lock = Caps_Lock
keysym Caps_Lock = Escape

and the following to ~/.bashrc

if [ "$PS1" ]; then
xmodmap ~/.Xmodmap

For Emacs's users: it's better to swap CTRL with Caps Lock, to do this, just put:

Option "XkbOptions" "ctrl:swapcaps"

inside Section "InputDevice" of your xorg.conf

If you use KDE, go to Control Center-> Regional & Accessibility-> Keyboard Layout-> xkb options, click "Enable xkb options" and there are some options under "Ctrl key position"

Thanks InYourBase for the KDE tip!
I am xmodmap aware, but KDE supercedes XModmap modifications, and I would never haved found these options by myself.
You made my day :-)

So cool! So nice to get rid of the blasted caps lock (especially for someone like me who cannot type (blindly) and hence cannot see what (s)he's typing. So nice :-)

I used to be removing the bloody CL key from all keyboards that I worked on manually, but that is not possible on laptops. Now this trick saves my day! Thanks!
KG - 18 February 2009 [«« Reply to this]
Ugh - thank you. My Eee PC laptop keyboard was damaged and the CL key was stuck on - this makes my laptop usable again until the new keyboard arrives...

wonderful abt Caps Lock...But I can you disable any key using same command.......
Peter Bengtsson - 28 March 2009 [«« Reply to this]
I actually don't know. I only just worked on the Caps Lock and haven't had a need to disable any other key. But I have thought about the Ctrl and Alt keys on the RIGHT because I never use them and perhaps they can be used for something else like to change language or something.
fred - 20 May 2009 [«« Reply to this]
First, thanks to Peter!

@kalpesh: maybe not exactly the answer you are looking for but I believe it's "yes, you can". No HowTo provided here, though... But combining "man xmodmap" and xev, you can probably do miracles with your keyboard ;-)

How do I toggle the capslock on and off? What I mean is, if I type `LS` or `CD` in bash, I'd like LS and CD alias to turn off caps and send `ls` or `cd` commands. I don't want to deactivate caps completely, I just want to be able to toggle it off when I forget I have it on.

I believe we need a new world-wide movement. The only possible use of caps lock is for lawyers-who-shout-to-make-it-seem-important and other misguideds. We will sneak into the keyboard factories and modify the production hardware to omit the caps lock key. A hole like a missing tooth. Finally we'll be able to stop all this effort disabling something that should NEVER have been there.

I am also an intense hater of CapsLock,
and was happy to find your excellent tip, which has worked well so far. But on my new Installation, whenever i open a new terminal (Ctrl-Alt-T) from an open xterm, i get a message like the following in the new window

xmodmap: please release the following keys within 2 seconds:
Control_L (keysym 0xffe3, keycode 37)
Shift_L (keysym 0xffe1, keycode 50)

before the fist prompt appears (BTW; i hadn't pressed any of those keys). This message does not appear when xterm is started from the menu. When i remove the xmodmap-command, this message does not occur. Does anybody know what this means?
JW - 14 December 2014 [«« Reply to this]
For people stumbling upon this post, 4 years later:

The problem "please release the following keys within 2 seconds:" happens when the xmodmap command is executed while the keys are held down. By adding the commands to ~/.bashrc, they are executed each time a terminal is opened, causing this error to appear each time.

In fact, you only want to run the xmodmap command once, when you log in. So, add it to ~/.bash_profile or ~/.profile instead (these are only run once)! Also make sure you don't include .profile from .bashrc (which I unfortunately did and spent much time figuring out...)

Yes you did: you've just told us you pressed Ctrl, and I'm guessing that you pressed Shift as well (rather than Alt) if you're in Gnome.
I get
t (keysym 0x74, keycode 28)
as well.
I don't know the answer yet, but it's clear what's going on.
