The Lenovo IdeaPad Pro 5 Gen 8 is a 14" (14APH8) or 16" (16APH8) laptop with AMD Ryzen 5 7640HS or Ryzen 7 7840HS processor. Both models were announced in December 2022, but went on sale at different times - the 16" model in April 2023, and the 14" model a little later, in July 2023. [1]
The 14" and 16" models differ in chassis, keyboard, screen, and the option for NVIDIA GeForce dGPU on the 16" model.

Troubleshooting
Screen
- The 14" 2800x1800 120 Hz screen operates only in 60 Hz mode. dmesg contains error messages about invalid DisplayID checksum.
Note
The incorrect EDID checksum (hex) is f0 98, should be f8 90.
The incorrect EDID checksum (hex) is f0 98, should be f8 90.
Solution:
Verify that the checksum is the incorrect one:
root #hexdump -C /sys/class/drm/card1-eDP-1/edid000000f0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 f0 98 |................|
Create a modified EDID with the correct checksum in /lib/firmware/edid/edid.bin:
root #mkdir -p /lib/firmware/edidroot #cp /sys/class/drm/card1-eDP-1/edid /lib/firmware/edid/edid.binroot #printf '\xf8\x90' | dd bs=1 seek=254 conv=notrunc of=/lib/firmware/edid.binVerify that the checksum is now correct:
root #hexdump -C /lib/firmware/edid/edid.bin000000f0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 f8 90 |................|
If DRM is built-in, then add this to the kernel configuration:
KERNEL Add custom EDID to kernel
Processor type and features --->
[*] Built-in kernel command line
(drm.edid_firmware=eDP-1:edid/edid.bin)
Device Drivers --->
Generic Driver Options --->
Firmware loader --->
(edid/edid.bin) Build named firmware blobs into the kernel binary
(/lib/firmware) Firmware blobs root directory
Graphics Support --->
[*] Allow to specify an EDID data set instead of probing for it
If DRM is built as a module, you can do the above, or instead create a file in /etc/modprobe.d/
FILE
/etc/modprobe.d/drm.confoptions drm edid_firmware=eDP-1:edid/edid.bin
