Overview

Some users - particularly those using laptops - are encountering a problem where the screen brightness is too dim upon replacing Microsoft Windows with a Linux distribution as their main operating system. This is because some unscrupulous hardware manufacturers have coded the BIOS to automatically disable the screen backlight if Windows is not detected running on the system. Fortunately, it is possible to fix this problem by entering a single command in the terminal.

Reactivating the Screen Backlight

This problem can be easily fixed by ensuring that the GRUB bootloader re-activates the backlight. To do this, first open up your terminal, and enter the following command:

user $  sudo sed "s/\(GRUB_CMDLINE_LINUX=\)\"\"/\1\"acpi_osi=Linux acpi_backlight=vendor\"/" /etc/default/grub -i COPY TO CLIPBOARD

You will also have to enter your password to continue. Now enter the second and final command:

user $  sudo update-grub COPY TO CLIPBOARD

Tamamlandığında, terminali kapatın ve değişikliklerin kalıcı olarak etkili olması için sisteminizi yeniden başlatın.
