Adjust brightness in Samsung Laptop
 

I am using a Samsung laptop and I found a workaround to adjust the brightness.

just press Alt+F1 to get the terminal only session.

login as root
type this command

echo 1 > /sys/class/backlight/acpi_video0/actual_brightness( for decreasing brightness)
echo 6 > /sys/class/backlight/acpi_video0/actual_brightness( for increasing brightness.)

Hi, thanks for your solution.

To make it so, check out the forum tools, you can and may set this as a solution which will make it easier for others to find a "solved" solution.

Cheers and thanks,

Regards Glenn
