Lack of brightness control in linux

[rkdeshdeepak]

I am having the  problem on my HP Victus laptop in arch linux, that I have no control over brightness and its quite dim. I have researched and found that the problem persist on all distros on victus laptops. By default the direcyory in /sys/class/backlight is amdgpu_bl1 and brightness is quite low and can't be increased and is reversed 0 (highest) 255 (lowest).

If I pass kernel parameters acpi_backlight=video, the directory is acpi_video0 and brightness is max, the vakues can range from 0-49 but has no affect, can't decrease brightness. Please help me or provide instructions to solve this.
