Remap keys on Ubuntu keyboard.

 I finally found the right way to remap keys in Ubuntu. 

This only works for later versions of udev so check your version.

udevadm --version

Should be 240+

sudo systemd-hwdb update   # if it's not

First find the keyboard to remap

sudo evtest

pick the keyboard by event id. Note the id (say it's 4)

press keys you want to remap and note the 'value' on the MSC_SCAN line on the key you want to change

press the key you want to map to and note the KEY_XXXX code

We will need the modalias, so 
> cat /sys/class/input/event4/device/modalias

Now you need to make a file
sudo gedit  /etc/udev/hwdb.d/10-my-modifiers.hwdb 

Here is mine:


The format needs to be exact. There is one space before KEYBOARD_XXX.
The key codes are lowercase.

So now you need to load the config
> sudo udevadm trigger
> udevadm info /dev/input/event4 | grep KEYBOARD

You should see your mappings are active.

Now even if you reboot your mappings should still be there.

Do I have anything I should have pushed?

I have a code folder. Under that I have subfolders for each repo I use. 

Do I have any work in any of these folders that needs pushing? 

 for /d %d in (*) do (pushd %d && git branch && popd || popd)

all on master.. so nope.
