Disabling bluethooth and setting default screen brightness on startup(Ubuntu)

I have noticed a few annoying things in ubuntu, two of them are

• By default system will power on bluetooth automatically
• Screen brightness restored to maximum on every reboot

Hopefully we can make default settings to the above mentioned problems. All you need is to add a few lines of commands to rc.local file

Open rc.local :

sudo vim /etc/rc.local

Add the following lines to the file before exit 0

echo 0 > /sys/class/backlight/acpi_video0/brightness
rfkill block bluetooth

save and exit vim
The first one will set the screen brightness to 0 and the second one will disable bluetooth at startup.Reboot the machine to see the changes.
