I know this question has been asked before, but I have tried the solutions, and they have not worked. First, I found this website about it. I tried the solution it gave:
sudo systemctl enable sddm.service -f
I was thrown an error:
Failed to execute operation: No such file or directory.
Then I went on to here to look for a solution. I found this thread about it and tried what the user recommended:
And found that my defualt display manager is /usr/sbin/gdm.
I then tried:
sudo systemctl enable gdm.service -f
It didn't work. So, for anyone willing to help, please do. It is literally my first day running linux and I have this issue.
