Fix: Laptop Screen Backlight Brightness Reset on Every Startup/Restart


The resetting of laptop screen backlight brightness on every startup/restart has been a common problem on my Asus N53SV and HP mini 210, both are gear up with elementary OS. Same thing happen as well after laptop come out of sleep mode which is annoying I have to adjust the screen brightness again. To get the screen brightness right, here is a solution:

  1. Open Terminal.
  2. Type sudo nano /etc/default/grub
  3. Find GRUB_CMDLINE_LINUX_DEFAULT="quiet splash". Replace the whole line with GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor" as screenshot below.
  4. Press ctrl + o to WriteOut/Save and press ctrl + x to Exit.
  5. Reboot your laptop.

  1. There're three ways to password protect flash drive. The first one is to use BitLocker if you are using Win7, Win 8, this feature is designed for drive protection. The second is to purchase encryption flash drive hardware such as Kingston, this kind of drive has built-in encryption feature, but it costs much. The last solution is to use software to encrypt the files in flash drive. Folder Protector is software that can password protect files in flash drives: http://www.kakasoft.com/folder-protect/

  12. Hello there! This tutorial is 100% workable! I thought my Nokia C6-01 wouldn't be reset but thank you to this and to Shala.. Good job guys! 2 thumbs up for you two! To other people who is experiencing the same thing, download the NSS Pro (Nokia Service Software Professional) Version 0.52 and not the Nemesis blah blah. The latter is a pirated version and will not install properly and eventually will not reset your Nokia.

As stated above, it had its issues therefore it will not install properly and eventually will not reset your Nokia. Kudos to Mok and Shala. *_*
