http://askubuntu.com – 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: nvfx_screen_get_param:95 - Warning: unknown PIPE_CAP 30 nvfx_screen_get (HowTos)
