The DSDT entries for the P2 Max are broken, but Github user PeterCxy has built a CPIO override which resolves the problem.
Steps:
- Download the latest
acpi_override
file from his releases page - Add the
acpi_override
file to the root of your EFI partition (aka/boot
) - 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
