I’m on Linux Mint 19.1, on a Laptop with a GTX 1060 mobile GPU. I’m using Prime to be able to utilize my iGPU when I don’t need the dedicated GPU. Whenever I don’t boot up directly into Nvidia mode and stay in it, a problem occurs where all the dark colors are mode really dark to the point where it makes things look awful. It doesn’t seem to effect everything. The thumbnails in the file manager, for instance seem unaffected. I’ll post some images for illustration, as well as my error log:

I tried downgrading from driver 415 to 390 (just using the driver manager), and that made no difference.
Edit: Nevermind, I was able to fix it by changing the color profile.
