well my pain in ass started eventually when I tried to boot up.
After booting, all I got was a black screen with no cursor. I figured something was wrong with the bootloader and started surfing the internet looking for a solution. But I was wrong.
Somehow, I magically managed to enter my password during the black screen and Kubuntu booted up fine.
Before that, I tried downloading drivers, messing with Grub, and messing with the BIOS. Nothing helped, just the opposite. When I decided to completely reinstall the system, the problem persisted, to my surprise.
Then I decided to try downloading version 25.4, and it worked fine right away.
I don’t even know what could cause it, but the fact that reinstalling does not help maybe says that it’s a bug or smth?
So, eventually I try to launch SDDM thru the konsole and get this:

I couldn’t find any info that could help me.
Any ideas?
