I'm having a black screen before login screen on kubuntu

ca flag

My kubuntu has been giving me problems for the past few days.

It was first showing a black screen with a cursor on the screen and I then stopped and started the sddm service and the login GUI came back.

After that my user wasn't logging in but another created user was logging in. So I entered the terminal in the login screen with ctrl+alt + F5 .

I discovered that my current files and folder was owned by www-data, I then changed the ownership to my username and the group to my username group .

The I successfully logged in. Then I added my username to www-data group so I can edit and save files on my local server. Then when I rebooted the laptop, my login details was not working again just like before.

I then entered the terminal again in the login screen and removed my username from the www-data group and then rebooted the system.

Since then my laptop just shows a black screen after the logo during booting. there's no cursor on screen and also I can't enter the terminal again.

So please how do I resolve this?

You should include the exact details of the steps you have taken in a way that is unambiguous so that we could reproduce your steps exactly. For example "*I then entered the terminal again in the login screen and removed my username from the www-data group*" - doesn't actually tell us exactly what you did. All of your details are ambiguous in this way. Please edit your question and include more specific details.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
