Thanks for the patch, ubuntu 20.04 is not working on the hp 635 device.
it was disappointing for me. ubuntu 16.04.7 version is used without any
errors. My advice is to use the 18.04 version or the 16.04 version. at
least for a while. :)

Sure I will update the information here.However, this will take a while,
i.e. patch review -> mainline kernel -> stable kernel -> Ubuntu focal
kernel.
It is the same as using the kernel parameter, and the patch will not
conflict with kernel parameter either.

Please try the kernel @
https://people.canonical.com/~alexhung/LP1894667/
1. remove kernel parameter "acpi_backlight=video"
2. download all deb
3. install kernel by "sudo dpkg -i *.deb"
4. reboot
This should be the same as "acpi_backlight=video"
1. run "ls /sys/class/backlight"
2. verify
This is kind of expected since it is common that systems from 2011 use
ACPI video interface. You can add the kernel into /etc/default/grub to
make it consist across boots.
I will compile a linux kernel with a workaround of
"acpi_backlight=video" for testing. If this work I can submit to linux

Let's try manually whether backlight interfaces work.
cd /sys/class/backlight/radeon_bl0
# get max brightness
cat max_brightness
# get current brightness
cat brightness
# change current brightness, assuming max=12
echo 12 | sudo tee brightness
echo 6 | sudo tee brightness

are available.
You may also want to try the kernel parameter for backlight such as
