The DSDT entries for the P2 Max are broken, but Github user PeterCxy has built a CPIO override which resolves the problem.

Steps:

1. Download the latest `acpi_override` file from [his releases page](https://github.com/PeterCxy/gpd_p2_max_acpi/releases)
2. Add the `acpi_override` file to the root of your EFI partition (aka `/boot`)
3. Add an `initrd=/acpi_override` kernel option to your boot manager - above any other initrd entries (`GRUB_CMDLINE_LINUX` in `/etc/default/grub` for grub; `/boot/loader/entries/*` for systemd-boot)

Notes:

- No xorg calibration config is needed
