How to set gamma at start up?

[G-Wiz]

Hi, when I set the gamma in nvidia settings, it never saves. It remembers the setting, but I have to launch nvidia settings for it to actually set the gamma.

Someone recommended an app galled Gammy, and while it's a great app, it only adjusts brightness, not gamma.

Is there a way to make it apply at start up?
Thanks

Well, after some effort I've solved this issue. For others having this problem I'll write out how I fixed it. Gummy and gammy both alter brightness but not gamma so I ended up not using them (they were recommended to me as gamma adjusters).
I found a program called xgamma that works perfectly. I had issues getting it to apply at startup, but what I did was create a bash script with the appropriate xgamma command then added that script to autostart.sh (since I'm using awesomewm).
