Hello, i just changed my screen resolution and my screen just got offset to the right so, using xvidtune i could change it back to normal, but i cant save changes so i saw that i have to use xvidtune -show and copy that to XF86Config-4 but i dunno where do i have to paste it... i mean i pasted it into "monitor" section but didnt work...

Here's my XF86Config-4 file:
