Slimbook Executive 14 tweaks

A bunch of useful tweaks for this laptop tried under Debian Trixie. I have the version with the 11th gen i7.

Keyboard

Set a keycode (macro) for Fn (usually unset) via systemd service at start

see/copy/modify init-setkeycodes.service to /etc/systemd/system/ (see bellow for how to mod)
systemctl daemon-reload to reload available services
systemctl enable init-setkeycodes.service to enable it on every boot
systemctl start init-setkeycodes.service to start it (now)
systemctl status init-setkeycodes.service to check the status

Note that this will only work in keyboards that map Fn to a scancode, usually you can see a warning in dmeg when you press Fn:

[   51.336674] atkbd serio0: Unknown key released (translated set 2, code 0xf8 on isa0060/serio0).
[   51.336687] atkbd serio0: Use 'setkeycodes e078 <keycode>' to make it known.

In this case the scancode for Fn is e078.

You can select an unused keycode to do this via xmodmap -pke, I used macro which is 120, for setkeycodes you need to remove 8 so it's 112.

Use keyd to set keycode for Fn (macro) to map Fn+delete to insert (which is missing in this laptop)

clone the repository
make and install keyd: make install
see/copy/modify+copy the keyd.conf file to /etc/conf (see above+bellow+man for info and what to mod)
enable keyd service if not enabled
restart or reload keyd
verify with xev if it's working

Keyd is akin to QMK but running as a virtual keyboard, and let's us work with layers. I just added one for Fn and added delete being mapped to insert.

[ids]

*

[main]

macro = layer(macro_layer)

[macro_layer]

delete = insert

Use keyd to add easier mappings for {} on an iso keyboard using the Fn layer

I mapped the pt layout keys:

Fn with ' and « to ( and )
Fn with + and ´ to [ and ]
Fn with º and ~ to { and }

Note that this one is dependent on the actual layout. The input key is in ansi, but the output will have to be the correct combination for the symbol on your layout. E.g. in the portuguese layout { is alt-gr + 7, hence G-7 on keyd.

*

[main]

macro = layer(macro_layer)

[macro_layer]

delete = insert
minus = S-8
equal = S-9
[ = G-8
] = G-9
' = G-7
\ = G-0

Power management

TLP

install tlp via apt
verify if you're running the correct driver scaling driver (e.g. intel_pstate on modern intel)
see/copy/modify+copy tlp.conf to /etc/tlp/

TLP allows us to control exactly how the laptop behaves when disconnected from power, and extend battery life.

See tlp.conf the configuration, but mostly it:

reduces GPU and CPU clock
changes power modes
