Please run "ls /sys/class/backlight/" to see what backlight interfaces are available.

You may also want to try the kernel parameter for backlight such as below

        acpi_backlight= [HW,ACPI]
                        { vendor | video | native | none }
                        If set to vendor, prefer vendor-specific driver
                        (e.g. thinkpad_acpi, sony_acpi, etc.) instead
                        of the ACPI video.ko driver.
                        If set to video, use the ACPI video.ko driver.
                        If set to native, use the device's native backlight mode.
                        If set to none, disable the ACPI backlight interface.

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=120000
echo 120000 | sudo tee brightness
echo 60000 | sudo tee brightness

Once done, did you see brightness changed?

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 kernel and you will not need to add kernel parameters in the future.

Alex Hung (alexhung) wrote on 2020-09-10:

#31

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 whether brightness bar works.

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.

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. :)

Do not use version 18.04 either, computer boot failed.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-groovy' to 'verification-done-groovy'. If the problem still exists, change the tag 'verification-needed-groovy' to 'verification-failed-groovy'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
