Lenovo Legion 5 Pro 16ACH6H — Getting 165 Hz on Linux

Get 165 Hz working in hybrid GPU mode on Linux

TLDR; Use a custom EDID block and load it at startup.

In hybrid GPU mode on Linux, the display is driven through the iGPU, which often fails to advertise the panel’s full 165 Hz capability. The fix is to acquire the correct EDID from the dGPU and force-load it at boot.

  • Boot into Hybrid GPU Mode
  • Use xrandr or wlr-randr to find your display ID — it is usually eDP-1
  • Reboot into Discrete GPU Mode
  • Open nvidia-settings → GPU 0 (Nvidia GeForce RTX 3060 Laptop GPU) → DP-4 (CSO) → click Acquire EDID
  • Place the acquired EDID file at /usr/lib/firmware/edid/edid.bin
  • Add the following to your kernel command line: 
    drm.edid_firmware=eDP-1:edid/edid.bin

    If your display ID in hybrid mode is not eDP-1, adjust accordingly.

  • Include the EDID file in your initramfs so it is available early in boot:
# /etc/mkinitcpio.conf
# ...
FILES=(/usr/lib/firmware/edid/edid.bin)
# ...
  • Rebuild your initramfs and reboot:
sudo mkinitcpio -P
