Thats stopping plymouth
You may be missing something or other.
(Most notably kms is helpful in minimizing blackscreens from plymouth. But it isnt a cure-all.)
But plymouth can also just break things on its own. Heres a guide for the interested:
So you have multiple unsupported packages that dont exist in the repos or the AUR.
(and 2 that are simply in the AUR and out of date but that that you probably dont need)
Do you need to be told to remove them?
Really only you know about the importance of any packages on your system.
But if you really have no idea … then they should all be deleted.
