i found out that to get dual monitors i need to make a xorg.conf file which i did, i restarted X and i thought it worked because the default kali background was on both screens but when i logged in screen 2 became completely white. Then i changed the xorg file from this:
Code:
Section "Screen"
	Identifier "Screen1"
	Device     "Card1"
	Monitor    "Monitor1"
	SubSection "Display"
To this:
Code:
Section "Screen"
	Identifier "Screen1"
	Device     "Card2"
	Monitor    "Monitor1"
	SubSection "Display"
This made the second screen show text about usb and other devices so i rebooted and then it wouldnt even get to POST screen which may have been my overclock not being completely stable. so i cleared the CMOS and now my desktop has 2 of everything on it except for program icons, with only screen 1 working.
NOTE: in xorg file screen 0 is screen 1 and screen 1 is screen 2, also all menus and other duplicates work completely and opening one wont make the other open also, such as the 2 'applications' menus when, I click on the right one only the right one opens.
