I have a HP Pavilion p7-1207c pc with a AMD Radeon HD 6530D integrated graphic card. The problem I’m having is when I closed the monitors and reopen them the screen is fuzzy; The same problem occurs when I restart. The way I get it to work is I open and close the monitors a few times and it works properly. Is there anything I need to install? I am using Ubuntu 12.10 with 2 monitors.
