Failed to start light display manager, tried basic forum posts

Hey guys
A bit late here but updated my system and had the same issue… Idiot pamac tried to install 5.10 kernel AND linux-latest kernel (also 5.10) and I think linux-latest won the fight…

I removed both then just installed 5.10 ( and the issue is gone so I’m guessing they fixed it in a point update, no need to edit mkinitcpio, checked mine and the amdgpu entry is not in there
