After windows boot, I see acpi_video0 with type equal to firmware . 2. The first reboot of Linux didn't change anything. 3. After the second reboot, acpi_video0 disappeared, which allowed powerdevil to select the correct device - amdgpu_bl2 I understand that changing the device selection logic may break other systems, but adding a config with the ability to hardcode the correct device won't hurt anyone. -- You are receiving this mail because: You are watching all bug changes.
