I've got a Dell Latitude E6510. I've got FC13 and Windows 7 dual booting on the machine. Both were living in harmony with one another, no problem. Only issue I was having, was that when I plugged my external 19" dell monitor, my linux would do 1 of 2 things..
1) if plugged up prior to boot, it would black screen after the fedora boot screen that shows the blue heart
2) if plugged up post boot, it would freeze the computer
The last thing I did to troubleshoot the issues was install system-display-config, maximized the screen resolution in the settings of that app, and set the resolution to 1650 x 900 (i think it was 900, not sure). After reboot, I now get the screen below after the fc blue heart screen loads.
