So I have tested your custom kernel. It does not fix my problem: -if the brightness == max_brightness => the display is at max brightness but stable. -if the brightness < max_brightness => the display brightness is not stable (is flashing). the brightness is jumping back and fort on the value brightness and max_brightness
But the values are as you described (actual_brightness is equal brightness) Aspire-A315-41:/sys/class/backlight/amdgpu_bl0$ cat brightness 183 Aspire-A315-41:/sys/class/backlight/amdgpu_bl0$ cat actual_brightness 183 Aspire-A315-41:/sys/class/backlight/amdgpu_bl0$ cat max_brightness 255 Please tell me if I can test anything! Actually I have an other laptop Asus 315-41, but with discrete GPU with the same OS, it has the also a large actual_brightness value, but the brightness control works (as you described with the laptops you tested)... I'm not sure how long the other laptop will work correctly... :( -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1861925 Title: BrightnessOutofRange: Actual brightness for amdgpu_bl0 not in range 0..255 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1861925/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
