Yesterday, I had to install some firmware updates from my Windows partition, which got completed successfully. I loaded up Ubuntu to check if everything was alright after the update but when I did, my screen went black and it started showing me some colorful dots on the upper half of my screen. It loaded up Ubuntu when I pressed the power button again, but it reloads the page a few times before I can actually login
I want to know how I can make my Ubuntu boot up normal and smooth again.
