I have been experiencing a few problem with my monitor HP TS-19SV even with the newly released Ubuntu 12.04 (although, this had happened before on Ubuntu 11.10, 11.04, 10.10 and 10.04. Basically, from time to time, when I start my computer and got to the Ubuntu's desktop, I see quite a bit of black lines next to my cursor and when I move the cursor up to the limit of the screen, the desktop fills with those weird lines. Something similar happens when a move the cursor at the bottom of the screen. Obviously, an image will be more helpful than my attempt of description:

When I reach the bottom of the screen:
When I reach the top of the screen:

UPDATE II: The answer given by Luis Alvarado solved this issue. There is still a weird fading effect when I shut down / Log out that happens when there is a process waiting to be closed but for the most part, everything is working great.
