Hi, I've just istalled deepin first time and I have problem with brightness. When I change brightness it makes white page grey and colors are faded instead makes screen backlight lower. For example the cursor is still bright.

How can I fix this?

Thanks.

I found the solution
  1. sudo tee /sys/class/backlight/radeon_bl0/brightness <<< 50
Copy the Code

works for me

But is it possible to make the "brightness settings" or fn keys work properly?

Some computers, like mine need one or both of the options in grub: acpi_osi=Linux acpi_backlight=vendor
e.g. GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux acpi_backlight=vendor"

I don't know how it works, but I had fresh install of Windows 10 on my computer and when I installed all drivers on Windows it started working normally on Deepin too
