I'm using Kubuntu. The problem I'm facing is that system startup gets stuck... After the grub menu, I see "kubuntu" on blue screen and flashing dots for a while. Then there is a blink and system goes to text mode. I can see some startup messages (The last one is something about the battery). Then it just stops and does nothing... I can press Alt+Print_Screen+K and then there is another blink after which the system enters the graphic mode again. I see NVidia logo for a couple of seconds and then the kdm login screen. I can login and use system as usually.
Does anyone know a way to solve the problem?
