I just transferred a HP pavilion dv2000 from windows to Ubuntu 12.04.

When it starts up there there are lines across the screen and after I log in, The mouse can't reach the edge of the screen on the left and if you touch the top of the screen with the cursors, a bar runs top to bottom and stays there as long as it touches the top. If you close and open the screen several times, sometimes it goes away.

i found a suggestion in a forum to check the print out of:

/usr/lib/nux/unity_support_test --print

it printed this:

Did you try installing the proprietary nvidia drivers? –  MiJyn Dec 15 '12 at 1:33

I also get that in Ubuntu 12.10 Alpha 3 VM. (Don't worry, now I have 12.10 final and that problem is fixed).

The EASIEST way that worked for me is log off the PC and log in again. Then, you will not see that anymore! BUT, if you shut down and start the PC later, you should repeat again (log off the PC and log in again).
