So I once tried out KDE Plasma by installing kubuntu-desktop. I then uninstalled it, but forgot to do auto-remove. I had to remove all software manually (it's all gone now) but I got another problem: Wrong logo shows when booting up my PC, instead of showing my manufacturer logo (in this case, ASUS), the Ubuntu logo, and the loading circle. When the Kubuntu logo is not showing, it shows a black screen. What can I do about this?
Note: I am a pretty new Linux user
