I installed the FC3 Test 1 on my laptop last week and the dual head display worked just like Windows XP. Today, I updated my system with the up2date and around 326 updates were done.
Now the dual head doesn't work anymore. This is what happens,
When the 2nd screen is attached to the laptop then, the second display is acting as the primary display and laptop screen doesn't display anything. If I remove the second screen from the latop then the first display works fine. I played around with the configuration file and no luck.
My laptop is DELL c640 and it has the ATI Radeon 7500 adaptor.
Any help is appreciated.
