I tried adding to /etc/default/grub “e_native_backlight=1” to GRUB_CMDLINE_LINUX_DEFAULT and then ran sudo grub2-mkconfig -o /boot/grub2/grub.cfg, but the problem still persists.

The output of cat /sys/class/backlight/nvidia_0/actual_brightness and cat /sys/class/backlight/nvidia_0/brightness are the screen brightness value set from the Fn key. Ls /sys/class/backlight/nvidia_0/ shows nvidia_0.

I can use the Fn key to change the screen brightness value, but the screen brightness isn’t changed it’s always at the max brightness. The graphics driver is NVIDIA proprietary driver version 510.xx via YaST. The laptop has discrete graphics mode, which is the mode where integrated graphics is disabled and the display is connected directly to the discrete graphics (not via integrated graphics). I have a problem with Lenovo Legion 7 laptop that the screen brightness cannot be adjusted and when waking up from sleep, it’s only black screen.
