Additional setup for Thinkpad X1Y3

Vim and media keys

I use AltGr + H,J,K,L as arrow keys and U,I as Prior and Next keys; CapsLock is mapped to Escape and Shift+CapsLock to CapsLock. Additionally, the Thinkpad X1Y3 does not have media keys, so I map Prior, Next and ↑ to Previous track, Next track and Play/Pause.

# Dependencies
sudo apt-get install xcape -y

# Config file
ln -srf scripts/customkeys-config.lst ~/.myscripts/.customkeys-config.lst

# Link script to a directory in HOME
mkdir -p ~/.myscripts
ln -srf scripts/apply-keymappings.sh ~/.myscripts/

# Create startup entry
mkdir -p ~/.config/autostart
ln -srf config/autostart/keymappings.desktop ~/.config/autostart/

Touchpad drivers

Linux Mint 20 uses libinput instead of Synaptics by default, but Synaptics provides lots of config options for the touchpad, with Kinetic Scrolling being my favorite. Check the drivers you're using with:

grep -i "Using input driver" /var/log/Xorg.0.log

Synaptics and libinput can coexist (libinput for keyboard+mouse and synaptics for the touchpad) by simply installing the package and restarting:

sudo apt-get install xserver-xorg-input-synaptics

TrackPoint and Logitech M570

Change DPI easily (using libinput).

# Link dpi script to the PATH folder
mkdir -p ~/.myscripts && ln -srf scripts/dpi.sh ~/.myscripts/
ln -srf scripts/trackpoint.sh ~/.myscripts/

# Use easystroke to bind the script to your preferred mouse button
sudo apt-get install easystroke

# Copy (my) saved configuration
rm ~/.easystroke && ln -srf config/easystroke/ ~/.easystroke

# Change config
easystroke

ThinkPad Compact USB Keyboard with TrackPoint

Temporal rant/thought process, I might put this in a blog/gitrepo later

So I bought a Thinkpad USB wired Keyboard (the first version that has the new "chiclet" keys layout).

The mic-mute key (Fn+F4) of this keyboard does not toggle the internal microphone, but the same key on the internal keyboard (Thinkpad X1Y3) does.

I ran xev to test if the X server detects the key, it detects all the other function keys, but not this.

Then I ran acpi_listen, it returns the following:

button/micmute MICMUTE 00000080 00000000 K

So the key is working at the BIOS level at least...

Okay, xev ignores the key, so I checked with evtest and found these keyboard devices:

No device specified, trying to scan all of /dev/input/event*
Available devices:
/dev/input/event3:	AT Translated Set 2 keyboard
/dev/input/event7:	Lenovo ThinkPad Compact USB Keyboard with TrackPoint
/dev/input/event8:	Lenovo ThinkPad Compact USB Keyboard with TrackPoint
/dev/input/event12:	ThinkPad Extra Buttons
Select the device event number [0-20]:

I selected event12, it seems to include all the hot keys of my internal keyboard, as the output when pressing the mic-mute key on my Thinkpad is:

Testing ... (interrupt to exit)
Event: time 1623859038.822635, type 4 (EV_MSC), code 4 (MSC_SCAN), value 1a
Event: time 1623859038.822635, type 1 (EV_KEY), code 190 (KEY_F20), value 1

Okay, so now I wanted to test this key but on my new external keyboard. Events event7 and event8 have the same name. When I select event7, I see the keycodes of "normal" keys (alphabet, tab, alt, etc) when pressing them, but the function keys are ignored.

Then I selected event8 and it seems to show the trackpoint AND the function keys of the USB keyboard! The output when pressing the mic-mute key is:

Testing ... (interrupt to exit)
Event: time 1623860131.478684, type 4 (EV_MSC), code 4 (MSC_SCAN), value ffa000f1
Event: time 1623860131.478684, type 1 (EV_KEY), code 248 (KEY_MICMUTE), value 0

So the keycodes are different for the mic-mute key (they are the same on other function keys), what's most important, the keycode of the mic-mute key of the external keyboard is 248. According to what I (barely) found on my research, this keycode is ignored by the X server.

The next step is to try to remap the key of the external keyboard to the keycode that my internal keyboard uses (KEY_F20), or to catch the acpi event and create a custom script to toogle the microphone on and off.

Most of the workarounds I found didn't work, I was about to give up, then I figured out the key (lol) was to connect to the acpid socket to catch the event.

This is the script I made, it simulates the keypress of the micmute button for the X server.

#!/bin/bash
coproc acpi_listen
trap 'kill $COPROC_PID' EXIT

while read -u "${COPROC[0]}" -a event; do
    [ "${event[0]}" = 'button/micmute' ] \
        && xdotool key XF86AudioMicMute
done

I gave it permissions (chmod +x thinkpad-extkeyb-micmute.sh), executed it:

./thinkpad-extkeyb-micmute.sh

... tested the combination Fn+F4 and .... It works!

Then I just created a startup entry.

# Link script
ln -srf scripts/thinkpad-usbkeyb-micmute.sh \
    ~/.myscripts/thinkpad-usbkeyb-micmute.sh

# Create startup entry
mkdir -p ~/.config/autostart
ln -srf config/autostart/thinkpad-usbkeyb-micmute.desktop ~/.config/autostart/

The advantage of my solution over all of the workarounds is that we let the X server handle this action, which means we don't need to toggle the mic with alsa/pulseaudio, nor do we need to implement a hacky workaround to toggle the LED of the button.

Most useful resources/discussions I found: This and this and THIS (rtfm).

Battery Managment

Change battery thresholds.

# Install TLP managment and dependencies
sudo add-apt-repository ppa:linrunner/tlp
sudo apt update
sudo apt install tlp tlp-rdw -y
sudo apt-get install acpi-call-dkms -y

# I keep charge between 50%-60%
sudo tlp start
sudo ln -srf config/tlp-battery.conf /etc/tlp.conf
sudo tlp start

# Check status
battery         # If using the custom bash profile.

Undervolting

Undervolt Intel CPU to decrease CPU temperatures.

# Install dependencies
sudo pip3 install undervolt

# I Undervolt by 120mV
sudo undervolt --core -120 --cache -120

# Or set a temperature target of 70°C
sudo undervolt --temp 70

Run at startup

sudo ln -srf scripts/undervolt.service /etc/systemd/system/

Check if script works, then enable it:

systemctl start undervolt
systemctl enable undervolt

Fingerprint login

The Thinkpad X1Y3 uses the 06cb:009a fingerprint reader, according to:

lsusb | grep "Synaptics"

This device is not supported by the widely used fprint, however, it supported by the new python-validity.

These are the steps to setup the fingerprint reader for the terminal and the Lock Screen.

# Install python-validity
sudo add-apt-repository ppa:uunicorn/open-fprintd
sudo apt-get update
sudo apt install open-fprintd fprintd-clients python3-validity

# The above will reset my keymappings :C
apply-keymappings.sh    # reapply my keymappings

# Scan fingerprints
fprintd-enroll          # scan finger ~10 times
fprintd-verify          # scan finger once

# Enable the fingerprint for authentication
# Select "Fingerprint authentication" with space bar
sudo pam-auth-update

NOTE: The Login Screen does not unlock the Keyring using biometrics (read this issue), it would ask for the sudo password anyway, so I disabled the fingerprint reader there (SDDM in my case). Open /etc/pam.d/sddm and paste the following after '@include common-auth':

# @include common-auth  # comment to disable the fingerprint reader
auth [success=1 default=ignore]	pam_unix.so nullok_secure try_first_pass
auth requisite pam_deny.so
auth required  pam_permit.so
auth optional  pam_ecryptfs.so unwrap
auth optional  pam_cap.so
# end of pam-auth-update config

Force a factory reset ONLY if you need to re-scan your fingerprints:

sudo systemctl stop python3-validity
sudo python3 /usr/share/python-validity/playground/factory-reset.py
sudo systemctl start python3-validity
fprintd-enroll
fprintd-verify

Prevent screen from locking when lid is closed

The settings-daemon for lid-close actions in miscellaneous.conf don't work in my machine... Here's a workaround to prevent hibernation and locking when lid is closed, this is specially useful when using multi-monitor setups.

Open /etc/UPower/UPower.conf and change IgnoreLid=false to IgnoreLid=true.

sudo nano /etc/UPower/UPower.conf

Open /etc/systemd/logind.conf, uncomment HandleLidSwitch=hibernate and change it to HandleLidSwitch=ignore

sudo nano /etc/systemd/logind.conf

Then reboot
