Sony Vaio Laptop monitor will not mirror external monitor

Asked by rickle

Sony Vaio VGN BX660p, just installed Ubuntu 14.04.
Boots up to laptop screen OK. (no external monitor plugged in)
Boots up to external monitor OK. (when external monitor plugged in)
System-Displays Shows both monitors, I can set them and select them.
It all looks fine except that the Laptop monitor is black, never turns on.
The only way I can find to get it back is to unplug the external monitor, and either reboot or logout and login again.
I can't use either mirrored or extended display. They were working with 12.04, it may have had the proprietary drivers I'm not sure, I installed a completely new 14.04 over top.

I did figure out that the keyboard change screen keystroke will switch it
back to the Laptop screen once the external monitor is unplugged. but that
doesn't help much.

With external monitor plugged in

The System Settings, Display program still does not work, It turns off the Laptop monitor, but I can live with this. Other programs like Impress seem to work just fine.
