Hi

I am using debian 12 on HP victus with two graphics card Nvidia 3050 and amd radeon (integrated). I dual booted debian on this laptop but I am not being able to control the brightness. I am using KDE plamsa. During shutdown, it takes a lot of time to shutdown and after checking the logs, backlighthelper is not shutting down properly. I tried to change desktop environment to cinnamon but I am facing same problem but with different service that controls the brightness in cinnamon. I have updated both nvidia drivers and amd drivers but nothing is working.
the output for
ls /sys/class/backlight/ is amdgpu_bl1

I am new to debian please help
