recently I formatted my computer and installed Windows 10. Next I installed Ubuntu 18.04. While using Ubuntu I wanted to power off. This screen appeared and I still can see it.
I also can see similar screens (for a second), but with much less text sometimes while starting the computer.
I don't experience a black screen with text now, but a few times after starting the computer it lags, and I can't move the mouse for a few seconds. I don't know what the problem is. I installed Ubuntu alongside Windows 10 with 50GB / (root) 70GB for /home and 32GB for swap because I have 32GB RAM.
