Just do:

git push origin master --force

or if you have a specific repo:

git push https://git.... --force

may not be proper, but if anyone stumbles upon this page, thought they might want a simple solution...

Short flag

Also note that -f is short for --force, so

git push origin master -f

will also work.

You all know about PWM Flickering:
Flickering
Monitor

Open your terminal and type this

xrandr -q | grep " connected"

it will gives you the output as LVDS1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 331mm x 207mm

There LVDS1 Stands for your display .

so now you have to do as

xrandr --output LVDS1 --brightness 0.5

there 0.5 stands for brightness and it ranges from 0.0 to 1.0 . 0.0 -> Full black .so you have to choose the required value of brightness.
