Hi Guys,

I am trying to make hardware acceleration work, but am not able to. Attached is my EFI directory. I tried various combinations of boot flags and device properties, specifically AAPL,ig-platform-id from WhateverGreen's framebuffer patching guide. I am stuck at IOConsoleUsers: gIOScreenLock.../gIOLockState (3...). I started off with prebuilt SSDTs, then to SSDTs generated with SSTDTime, and now compiled them manually. Still no luck. Below are my config.

Laptop: Alienware M15 R2
CPU: i7-9750H
GPU: Intel UHD 630 + Nvidia RTX 2070 Max Q
Screen: OLED 4k (if OLED makes any difference, except for brightness control)

I could successfully boot with boot flag "igfxvesa", but as expected with no gpu acceleration. I do not know how do I troubleshoot further form here. Any guidance/direction is appreciated.

For anyone interested, I've managed to fix it. Below is how device properties should look like.

After changing these, I get correct frame buffer.
