Hi everyone
i need help regarding environment variables

i want to use nvidia on-demand of 440 driver but i cannot find out how to set environment variable for it
i searched for 3hrs but i couldn't find a sample or a how to guide and it's killing me

The purpose is to set environment variable to run a program like handbrake with nvidia gpu
where and how should i set it?


Thanks

Oh and latte dock is causing my gpu to stay at 100% frequency when on nvidia only mode so i decided to use this method
And ubuntu-mate dock (pantheon theme in 19.10) is ok why latte eats so much gpu power?
