my notebook uses an onboard intel graphicscard and a mobile nvidia card. The screen of my notebook is way too bright so i wanted to use the terminal to reduce gamma.
When i use the intel graphics i can reduce gamma with the code
sudo xgamma -gamma 0.65 . In order to have the system do that on startup without me doing anything i found out the code for that is
/usr/bin/xgamma -gamma 0.65.
However using the nvidia card the code
sudo xgamma -gamma 0.65 won't work. i googled a bit and found out in order to change gamma while using my nvdia card i have to use
xrandr --output LVDS-1-1 --gamma 0.65:0.65:0.65 . But now i am kinda clueless what code i have to type in order to make that a startup code.
Can someone help me using the information provided here? i am honestly just copying and pasting stuff i find online without any idea what it means.
For the record: in my nvidia settings i can't change gamma cause my display is shown as "prime display" which has no settings at all.
