16.04 - Weird Nautilus / Unity look

i don't know caused weird behavior of nautilus, here screenshots demonstrate why looking weird:

icon size big , can not reduced.

no options, weird buttons style, big list size no options reduce it.

and i'm sure default theme.

you're using budgie remix ppa. can remove with:

sudo apt install ppa-purge sudo ppa-purge ppa:budgie-remix/ppa

this will

remove ppa repository list,
replace packages ppa next best package other remaining configured repository if 1 available and
remove other packages installed ppa.

you'll need start new desktop session (log out , in) changes take effect , without glitches.

for more info , alternative methods remove ppas see how can ppas removed?
