Install graphic driver for AMD Ryzen 7 5800U APU

I have brand new HP Zhan (hp probook 445 g8) with AMD Ryzen 5800u. The screen brightness is not adjustable, the HDMI and USB-C ports doesn't work. I can't connect to external displays. I'm using Ubuntu 20.04

WOW, after install the kernel 5.11.7 and latest linux-firmware 1.187.10 but the it doesn't solve the problem. I google something and found this post: Then I tried to comment out the blacklist amdgpu in /etc/modprobe.d/blacklist-amdgpu.conf then run the command sudo modprobe amdgpu. BOOM, it works. Now I can change the screen brightness, HDMI port works. AWESOME.
