How can I reload my XKB configuration without restarting my computer or logging back in

I made a cool, little script that will edit my /usr/share/X11/xkb/symbols/pc file automatically. It is useful when I want to switch between a Mac or Windows keyboard.

The one problem I've encountered is that I have to log out and then log back in after editing the file in order for the edited configuration to take effect.

I've tried deleting my xkb cache (/var/lib/xkb/*.xkm), but that did work.

Any help would be greatly appreciated. Cheers.

Solution. Run this command. Of course, you could change "us" to your desired keyboard layout.

setxkbmap -layout us

It's answered in Unix Stack Exchange:

Basically, you do this:

sudo udevadm trigger --subsystem-match=input --action=change

It is also mentioned that the following might be sufficient, please comment on what system setup it alone helped:

# For Ubuntu < 16.04
service keyboard-setup restart
# For Ubuntu >= 16.04
systemctl restart keyboard-setup

You might come across other answers suggesting you delete /var/lib/xkb/*.xkm. That would be an outdated suggestion. At least in Ubuntu, this directory wasn't used for this purpose for quite a few years.
