Re: 12.04 How to extend display on dual screen?
If you are using ATI card and proprietary driver then use CCC to setup Xinerama but if you use Open-Source ATI driver then you should play with your xorg.conf file, I managed to setup dual-head with it. So what is your call?
I had to go from Open-Source to Catalyst in 12.04 because Catalys solved a problem with heat and fan speed - only one reason why I was not using ubuntu so much, but with catalyst in 12.04 things seem to be muuuch better, have not tried yet to setup Dual-Head
