It seems that what I have been trying previously (updating my antergos firmware and packages), it didn’t work smoothly.
So, instead of getting more confused and repeat the same mistakes, and spent too much time on a same issue, I decided to remove everything except the base packages on my Antergos.
It might be so plain, but it is gonna be better.
[UPDATE] it turned out to be a disaster actually. even the GUI of my antergos was deleted during my experiment. I couldn’t figure out how to configure the GRUB. So I decided to say goodbye to antergos.
Now I have been switching to Ubuntu. As I use it on my vps as well.
