I'm new to Linux. Yesterday I removed Windows 10 from my laptop to install Ubuntu as I heard that it is much more efficient. It took me a day to understand how to install it. Now it is working very slow. When I start my laptop it takes almost 5-10 minutes to display the login screen. When the computer boots it asks for cleaning some files. I am new to Ubuntu and don't know much about it.
- i5 (5th gen)
- 8GB RAM
- Why is Ubuntu running that slow?
- What can I do to optimize the current situation?
