# Frakkin-XKB

For some reason in Ubuntu or Xorg in general it is somehow quite hard to

reliably configure custom XKB keymaps.

## Description

`xkbcomp` is a way to load custom keymaps from e.g. your home folder.

This allows one to customize keyboard layout beyond default options.

### Problems

#### Calling xkbcomp in .xsession

The options won't effect devices plugged in later.

#### Setting the XKB keymap and options in `/etc/default/keyboard`

This trigger a udev rule which sets some variables which are then used by

Xorg evdev driver. Problem is that using custom XKB rules with this will

require editing files in `/usr/share`.

Also LightDM tries it's best to mess up the keyboard layout, but this

should be fixable with `~/.Xkbmap`.

#### Using udev rule to call xkbcomp

Xkbcomp needs to run as user running the X session, this requires some

hacks. Additionally `RUN+=` rule in udev will block for duration of the

script and this causes Xorg to wait until the script is finished and then

to set the default options, overwriting our options.

### Solution

Call xkbcomp from `.xsession` and using `frakkin-xkb`:

xkblayout.sh:

```bash

#!/bin/bash

xkbcomp -I"$HOME/.xkb" "$HOME/.xkb/keymap/default" "${DISPLAY%%.*}"

```

.xsession:

```bash

xkblayout.sh

frakkin-xkb xkblayout.sh

```

Frakkin-xkb listens for XInput events and when new devices are adeed, calls the given command.
