What distro are you considering? I know e.g. Arch has a wiki page dedicated to the FrameWork and basically everything works.

It’s not this significant (3x). it should be closer to 7%. My guess is that OP is using something like btrfs, whose data used is calculated differently due to the CoW nature, and btop++ is using using a generic tool to estimate disk usage rather than the btrfs utility that DUA is almost certainly using.

the theory that neutrality is objective is fucking mind numbing. the right wing reactionary perspective is never, has never been, and will never be grounded in anything resembling facts. they consistently disregard actual evidence to promote bigotry and divide the working class.
