/ HP Spectre x360 (2018 Whiskey Lake) - Synaptics Touchpad Libinput Gestures Fix Linux.md

This just details how to overeride the default PS2 interface for the touchpad and force it to use RMI4. Not as good as having proper I2C but it makes gestures in gnome and niri SIGNIFICANTLY better on this piece of shit laptop
The Synaptics touchpad on this laptop defaults to a shit basic ps/2 interface on Linux. HP in their infinite wisdom decided to not use an I2C touchpad even though the touchscreen does use i2c (hence why its consistently better feeling in both windows 11 and on linux). And perhaps worse is that by default the legacy ps/2 drivers fight with the RMI4 Protocol from working, so you get absolutely abhorrent trackpad behaviour
The best solution is to override the basic ps/2 fallback and force the kernel to use the RMI4 protocol over SMBus (InterTouch). Still not as good as a native I2C connection but this drastically reduces lag and makes multi-touch gestures in libinput-based compositors (like GNOME and Niri) SIGNIFICANTLY better.
- Open GRUB config file:
sudo micro /etc/default/grub - Find the line starting with
GRUB_CMDLINE_LINUX=and append the flags inside the quotes. It should look something like this:
