change login screen and change start menu icon

I would prefer a very clean solid wallpaper for login screen when I boot. any how to this?

also can I change the start menu icon?

pretty new to linux. been using mint for 6 months. meh, has to go

You have to install the sddm-kcm package if you haven’t already, then go into system settings, search SDDM in the top left, open the only item, and in that menu in the selected login theme there is a wallpaper button. Clicking that allows you to select an image.

You can open the start menu, in the top right corner, next to the pin button there is the settings button and in that menu you can set the icon.

You should be able to change the entire layout in the ssdm settings.

some help for a linux noob please

I tried through the software manager to search for sddm-kcm/sddm/kcm but it didnt show up

I tried searching on youtube. it just shows videos on how to install themes through sddm

Try search via terminal/command. They are more accurrate than the software manager that are available. Which Distro are you using?
