Hi,
I have a acer aspire a315-41 laptop. I have a problem with the Backlight. I can not control.
According to: https://wiki.ubuntu.com/Kernel/Debugging/Backlight
It is : Backlight control does not work, but there are entries in /sys/class/backlight.
The problem is as far I could find:
sanya@Aspire-A315-41:/sys/class/backlight/amdgpu_bl0$ cat brightness
135
sanya@Aspire-A315-41:/sys/class/backlight/amdgpu_bl0$ cat actual_brightness
43500
sanya@Aspire-A315-41:/sys/class/backlight/amdgpu_bl0$ cat max_brightness
255
The brightness read from the HW is not in the range, and when I change the brightness by the keys the value in the brightness file changes too, but the actual_brightness is fix...
I have tried all the steps mentioned in https://wiki.ubuntu.com/Kernel/Debugging/Backlight
Actually I have tried all these kernel startup parameter variants without luck:
GRUB_CMDLINE_LINUX_DEFAULT=""
#GRUB_CMDLINE_LINUX_DEFAULT="video.use_native_backlight=1"
