I'm an ultra nooby beginner with Linux and Kubuntu, so please be patient :) Since yesterday I've got a stupid problem. When I turn on my PC, and when my login screen shows up, after 2-3 second it crashes - I see everything in horizontal lines, but I can write my password and enter the system. Unfortunately, after login in, screen still looks like before login.
But when I'll log out with keyboard combo, the login screen look's normal. After second login everything is fine till I restart the PC. Then everything repeats. Additionally, since there is a problem with screen, I've also noticed that my spacebar often doesn't work when I press it, so I need to press it again. Didn't tried it with other keys.
I have no idea what is happening. Please help! :)
Now, when I log in the OS (after second time, when everything's fine), KDWallet want's me to enter password and log into it. Got this few times since yesterday.
