Hi,
Is there a way to enable a blue light filter?
I'm using Xfce and the Settings:Display popup has nothing related to it.
Thanks.latest?d=yIl2AUoC8zA latest?i=DX-nW-5_VMg:3JT8PmgG_Es:F7zBnMy latest?i=DX-nW-5_VMg:3JT8PmgG_Es:V_sGLiP latest?d=qj6IDK7rITs latest?i=DX-nW-5_VMg:3JT8PmgG_Es:gIN9vFwDX-nW-5_VMg
