    HDMI Monitor on Open Source Radeon Drivers

    Hello fellas,

    Two weeks ago I buyed a brand new monitor for my laptop.

    I have a HP Envy 14 : http://h10025.www1.hp.com/ewfrf/wc/d...roduct=5054124

    It come with a Integrate Intel graphic card and a AMD Radeon 5650.

    I was with a Ubuntu 12.04 + gnome-shell and tried follow every tutorial that I found on the web... Till someone said that fglrx dosent wotk with muxless devices which is my case .
    "(EE) this is a Muxless PX A+I platform, we doesn't supported it"

    So then I installed Ubuntu 12.10 Gnome Remix and start trying with the radeon open source drivers and the xorg.cfg

    So now i have 2 problems:
    1. On Radeon drivers gnome-shell fallback to classic mode =(
    2. On one screen I have the top bar and the mouse pointer and in the other monitor I have the login and I cant move the cursor to the other monitor

    Here is my last try with xorg.conf
    Code:
    Section "Monitor"
            Identifier   "HDMI-0"
            VendorName   "LG"
            ModelName    "Flatron"
            HorizSync    30.0 - 83.0
            VertRefresh  56.0 - 75.0
    	Option	    "DPMS" "true"
    	Option	    "PreferredMode" "1920x1080"
    	Option	    "TargetRefresh" "60"
    	Option	    "Rotate" "normal"
    	Option	    "Disable" "false"
    	Option	    "Primary" "false"
    	Option	    "Position" "1366 0"
    EndSection

    		Option		"Disable" "false"
    		Option		"Primary" "true"
    		Option		"Position" "0 0"
    EndSection
    
    Section "Device"
            Identifier     "Card0"
            Driver          "intel"
            BusID           "PCI:0:2:0"
     	Option 		"AccelMethod" "sna"
    EndSection
    
    Section "Device"
            Identifier      "Card1"
            BusID           "PCI:1:0:0"
    	Driver			"radeon"
    EndSection
    																  
    Section "Screen"
    		Identifier "Screen1"
    		Device "Card0"
    		Monitor "LVDS"
    		DefaultDepth 24
    		SubSection "Display"
    			Depth 		24
    		EndSubSection
    EndSection
    
    Section "Screen"
            Identifier "Screen0"
            Device     "Card1"
            Monitor    "HDMI-0"
            DefaultDepth    24
            SubSection "Display"
    			Depth     	24
            EndSubSection
    EndSection
    
    Section "ServerLayout"
            Identifier     	"Layout0"
    	Screen		"Screen1"  0 0
    	Screen		"Screen0"  1366 0
    EndSection
    Any help will be appreciated

    Best regards

    Re: HDMI Monitor on Open Source Radeon Drivers

    I noticed something curious. With this config I have like 2 screen in one on the HDMI monitor.

    So diggin on the Xorg.0.log i found this:
    Radeon is detecting the 2 outputs:
    [ 17.160] (II) RADEON(0): Output LVDS using monitor section LVDS
    [ 17.240] (II) RADEON(0): Output HDMI-0 using monitor section HDMI-0
    And then Intel is detecting another output:
    [ 17.449] (II) intel(1): Output LVDS2 using monitor section LVDS

    What it could be? Any ideas?
