Hello Team,

First of all let me thank you for making such a beautiful linux distro available for general use.

I was extremly satisfied using the distro until this bug started ruining my experience.

Initially , the operating system was working fine. But once I started it the next day, I saw this error "drm: radeon_acpi_init Error: Cannot find a backlight controller" while booting in to the system. Its impact is so bad that the screen looks pretty dim  even on full brightness settings provided by Deepin OS. I searched online for a soultion and couldn't get a worthy one.

Request you to let me know a solution if available as I don't want to move back to Win or other linux distros after using deepin.

Best Regards,
Sunil
