I am trying to install Ubuntu 12 on my notebook, Acer Aspire 7715Z.
On boot up, system recognises Ubuntu and loads up installation screen. A few pages of white text roll down the screen and then the screen goes blank. I attached a 2nd screen and everything is visible. I choose to run programme from USB key and this goes ahead ok and OS is visible on 2nd Screen while notebook is blank.
I went into display settings and tried to make display visible on Notebook but nothing makes a difference. I switched off 2nd monitor and Mirror options and set display to maximum. When I hit Apply, 2nd monitor disappears and very faint shadow appears on notebook screen. I cannot brighten this from notebook keypad although volume control FN option buttons work ok.
I experimented with all options on settings menu but no change and don't have an idea of what to do now.
I want display only to appear on notebook, not second display.
