I had Ubuntu 18.04 installed on my Lenovo IdeaPad 720s (Intel Core i5-8250U CPU) and everything was working fine. Then I upgraded to Ubuntu 18.10 and now, I'm having a problem where it keeps freezing after login and it becoming entirely unresponsive. Does anybody else has a similar problem?
I really appreciate any help you can provide.
UPDATED: The problem was fixed after reinstalled Ubuntu 18.10. Now everything is working fine but I couldn't figure out what even happened. Thanks!
