Getting Xorg.conf working (radeon driver not found at boot)

When my /etc/X11/xorg.conf.d/00-monitor.conf file is read at boot, the 'radeon' driver is not found:

[    20.574] (II) LoadModule: "glx"
[    20.575] (II) Loading /usr/lib/xorg/modules/extensions/libglx.so

once I startx without this file though it seems I am using the driver 'radeon' that
didn't exist at boot:

here is my xorg.conf file:

        Option          "Primary"        "On"
        Option          "Rotate"         "Right"
EndSection

Section "Monitor"
        Identifier      "DVI-0"
        Option          "Rotate"        "Left"
        Option          "RightOf"       "DVI-1"
EndSection

Section "Device"
        Identifier      "Card0"
        Driver          "radeon"
        BusID           "PCI: 1:0:0"

        DefaultDepth    24
        SubSection "Display"
                Depth   24
                Modes   "1920x1200"
        EndSubSection
EndSection

Section "Screen"
        Identifier      "Screen1"
        Device          "Card0"
        Monitor         "DVI-0"
        DefaultDepth    24
        SubSection "Display"
                Depth   24
                Modes   "1920x1200"
        EndSubSection
EndSection

Been googling this for a few hours and trying different things but nothing really has worked.

Last attempted was adding 'radeon' to /etc/mkinitcpio.conf with no effect.

Can anyone help a arch n00b out?

Re: Getting Xorg.conf working (radeon driver not found at boot)

So I changed 'radeon' to 'modesetting' and everything seems to work. I looked at the /home/<user>/.local/share/xorg/Xorg.0.log to see what startx used when there wasn't a xorg.conf provided and saw it was using 'modesetting' so I just did the same.

My working xorg.conf is:

Section "Monitor"
        Identifier      "DVI-1"
        Option          "Primary"        "On"
        Option          "Rotate"         "Left"
EndSection

Section "Monitor"
        Identifier      "DVI-0"
        Option          "Rotate"        "Left"
        Option          "RightOf"       "DVI-1"
EndSection

Section "Device"
        Identifier      "Card0"
        Driver          "modesetting"
        BusID           "PCI:1:0:0"
EndSection

Section "Screen"
        Identifier      "Screen0"
        Device          "Card0"
        Monitor         "DVI-1"
        DefaultDepth    24
        SubSection "Display"
                Depth   24
                Modes   "1920x1200"
        EndSubSection
EndSection

Section "Screen"
        Identifier      "Screen1"
        Device          "Card0"
        Monitor         "DVI-0"
        DefaultDepth    24
        SubSection "Display"
                Depth   24
                Modes   "1920x1200"
        EndSubSection
EndSection

It also says in the logs that it is actually using 'radeonsi'? Not sure what 'modesetting' and 'radeonsi' are really can anyone explain?
