Fix Trackpoint drifting issue on Lenovo Laptops (Linux)
Recently, I encountered an issue with the Trackpoint on my Lenovo laptop where it would drift unexpectedly. After some research and troubleshooting, I found a solution that worked for me.
# Check current sensitivity value
cat /sys/devices/platform/i8042/serio1/sensitivity
echo 100 | sudo tee /sys/devices/platform/i8042/serio1/sensitivity
# And then test if the drifting issue is resolved.
# If the above command resolves the issue, you can make this change permanent by creating a systemd service.
sudo tee /etc/udev/rules.d/10-trackpoint.rules << 'EOF'
ACTION=="add", SUBSYSTEM=="input", ATTR{name}=="TPPS/2 Elan TrackPoint", ATTR{device/sensitivity}="100"
EOF
sudo udevadm control --reload-rules
