As the question statement explains itself, I'm on Ubuntu 14.04 and my screen brightness is reset to maximum after every boot, no matter how many times I reset.

I applied the solution provided here Brightness is reset to Maximum on every Restart But once, & it resulted into corrupting my Ubuntu Installation, I had to re-install my Ubuntu copy. Now I'm reluctant to try that again.

I need a safer method to set this problem straight.

Hardware: Laptop - HP Pavilion DV6 -7071tx

Screen Res - 1080p Full HD

Graphics - Nvidia GT650M

Ubuntu - Dual boot & Installed on 32Gb - SSD

Go to terminal and type sudo nano /etc/rc.local . A window will pop out, and add echo 5 > /sys/class/backlight/acpi_video0/brightness before the last line “exit 0″. Number 5 is the value of your screen brightness. With cat /sys/class/backlight/acpi_video0/max_brightness command you can check the maximum. This might work for you, Have fun.

That didn't solve it. But I just updated Ubuntu using Software Center (80Mb+) and it has solved my problem. The brightness state is saved on shutdown and recovered on restart dynamically. Just what I wanted. Thanks for help btw. – InamTaj Jun 10 '14 at 7:01
