[Solved] Xrandr does not detect external monitor

I recently just installed Arch linux on my laptop and decided to install the catalyst driver as well. I followed all the instructions on how to install catalyst and when I try to use the xrandr command it does not show my second monitor. I am using i3wm on the latest kernel and catalyst driver. I can also see a x cursor when I move my mouse to my other screen but it does show the i3bar or I cant drag a window to the other screen

Here is my xorg.conf

Section "ServerLayout"
	Identifier     "aticonfig Layout"
	Screen      0  "aticonfig-Screen[0]-0" 0 0
	Screen         "aticonfig-Screen[0]-1" Above "aticonfig-Screen[0]-0"
EndSection

Section "Module"
EndSection

Section "Monitor"
	Identifier   "aticonfig-Monitor[0]-0"
	Option	    "VendorName" "ATI Proprietary Driver"
	Option	    "ModelName" "Generic Autodetecting Monitor"
	Option	    "DPMS" "true"
EndSection

Section "Monitor"
	Identifier   "aticonfig-Monitor[0]-1"
	Option	    "VendorName" "ATI Proprietary Driver"
	Option	    "ModelName" "Generic Autodetecting Monitor"
	Option	    "DPMS" "true"
EndSection

Section "Device"
	Identifier  "aticonfig-Device[0]-0"
	Driver      "fglrx"
	BusID       "PCI:0:1:0"
EndSection

Section "Device"
	Identifier  "aticonfig-Device[0]-1"
	Driver      "fglrx"
	BusID       "PCI:0:1:0"
	Screen      1
EndSection

Section "Screen"
	Identifier "aticonfig-Screen[0]-0"
	Device     "aticonfig-Device[0]-0"
	Monitor    "aticonfig-Monitor[0]-0"
	DefaultDepth     24
	SubSection "Display"
		Viewport   0 0
		Depth     24
	EndSubSection
EndSection

Section "Screen"
	Identifier "aticonfig-Screen[0]-1"
	Device     "aticonfig-Device[0]-1"
	Monitor    "aticonfig-Monitor[0]-1"
	DefaultDepth     24
	SubSection "Display"
		Viewport   0 0
		Depth     24
	EndSubSection
EndSection

what xrandr -q shows

Screen 0: minimum 320 x 200, current 1366 x 768, maximum 1920 x 1920

   1024x768      60.00  
   1024x600      60.00

Re: [Solved] Xrandr does not detect external monitor

Never mind I just needed to delete my xorg.conf and regenerate it by

# aticonfig --initial
