I have tried changing the brightness.
added echo 4 > /sys/class/backlight/intel_backlight/brightness
to /etc/rc.local
But it is temporary change & still getting black screen while login.
How can we set the brightness settings permanently?

Can you try editing that line in /etc/rc.local
to instead be:
echo 4 > /sys/class/backlight/acpi_video0/brightness
That's what I have in my rc.local
file, and it works like a charm at every boot no matter what.
Have you tried going to startup Applications in the dash.
Add a new startup program "Brightness Level" and add in the command line: xbacklight -set XX
XX being the level you wan at boot. I think it's a 100 scale. I've set mine at 60.
Best,
