Default brightness to persist
I'm running Mint 17 Cinnamon 64, onboard intel graphics. The laptop boots up with the brightness set to max and it's chewing up my battery when I forget to turn it down. The brightness buttons work on the keyboard as does the settings in the System Settings Power menu but when I reboot it goes back to full brightness (while leaving all the other settings as I had them set). Is there a way to get this to persist on reboot? I want it to start at 50% but allow me to adjust it higher or lower depending on my preference and have it reboot back to 50% each time, regardless of previous settings.

I can make that happen
Code: Select all
cat /sys/class/backlight/intel_backlight/max_brightness
Code: Select all
gksudo gedit /etc/rc.local
Code: Select all
echo X > /sys/class/backlight/intel_backlight/brightness
Save file, close gedit and reboot

Nope. Still loads at full brightness.
