You be capable to endeavor to regulate the brightness by editing the "/ proc / acpi / video / VGA / LCD / brightness". You will discover a couple of entries in this file
Code:
levels: 0 40 100
current: 100
Another technique of doing this is issuing the command:
Code:
sudo cp /proc/acpi/video/VGA/LCD/brightness /proc/acpi/video/VGA/LCD/brightness.bak
sudo echo -n 100 > /proc/acpi/video/VGA/LCD/brightness
Sign indicates that the file is overwritten, so you first have to save as. bak. Instead of 100 for the highest, brightest level, you can specify 60 or 40 or any other value and see if this works for you. Much help if we knew what the display driver to help with other details. Try to publish the results of the command "inxi-G".
