X reads monitor and layout conf on boot but xrandr only shows Screen0

I've been setting up arch linux for a few days - mostly it's been easy to make progress but I'm having a real problem with multihead support. I have a Thinkpad X1 extreme with an Intel and NVIDIA video chip and hybrid graphics I've installed: - xf86-video-intel - xf86-video-vesa - bumblebee - bbswitch - lightdm - i3wm This is the xorg conf I'm using: Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" Above "Screen0" InputDevice "Mouse0" "CorePointer" InputDevice "Keyboard0" "CoreKeyboard" EndSection Section "Module" Load "dbe" Load "extmod" Load "type1" Load "freetype" Load "glx" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "keyboard" EndSection Section "Device" Identifier "intelgpu0" Driver "intel" Screen 0 Option "XvMC" "true" Option "UseEvents" "true" Option "AccelMethod" "UXA" BusID "PCI:00:02:0" EndSection Section "Device" Identifier "intelgpu1" Driver "intel" Screen 1 Option "XvMC" "true" Option "UseEvents" "true" Option "AccelMethod" "UXA" BusID "PCI:00:02:0" EndSection Section "Device" Identifier "nvidiagpu0" Driver "nvidia" BusID "PCI:01:00:0" EndSection Section "Monitor" Identifier "Monitor0" Option "Enable" "true" EndSection Section "Monitor" Identifier "Monitor1" Option "Enable" "true" EndSection Section "Screen" Identifier "Screen0" Device "intelgpu0" Monitor "Monitor0" DefaultDepth 24 Option "TwinView" "0" SubSection "Display" Depth 24 EndSubSection EndSection Section "Screen" Identifier "Screen1" Device "intelgpu1" Monitor "Monitor1" DefaultDepth 24 Option "TwinView" "0" SubSection "Display" Depth 24 EndSubSection EndSection This is the lspci -v output of the two video devices: 00:02.0 VGA compatible controller: Intel Corporation Device 3e9b (prog-if 00 [VGA controller]) Subsystem: Lenovo Device 2267 Flags: bus master, fast devsel, latency 0, IRQ 171 Memory at 404a000000 (64-bit, non-prefetchable) [size=16M] Memory at 80000000 (64-bit, prefetchable) [size=256M] I/O ports at 6000 [size=64] [virtual] Expansion ROM at 000c0000 [disabled] [size=128K] Capabilities: Kernel driver in use: i915 Kernel modules: i915 01:00.0 VGA compatible controller: NVIDIA Corporation GP107M [GeForce GTX 1050 Ti Mobile] (rev a1) (prog-if 00 [VGA controller]) Subsystem: Lenovo GP107M [GeForce GTX 1050 Ti Mobile] Flags: bus master, fast devsel, latency 0, IRQ 16 Memory at bf000000 (32-bit, non-prefetchable) [size=16M] Memory at 60000000 (64-bit, prefetchable) [size=256M] Memory at 70000000 (64-bit, prefetchable) [size=32M] I/O ports at 5000 [size=128] Expansion ROM at c0000000 [disabled] [size=512K] Capabilities: Kernel driver in use: nvidia Kernel modules: nouveau, nvidia_drm, nvidia When I boot, X seems to pick up the layout and screens alright (previously I had a hard time getting it to read past the first screen section): [ 2.312] (==) Using config directory: "/etc/X11/xorg.conf.d" [ 2.312] (==) Using system config directory "/usr/share/X11/xorg.conf.d" [ 2.314] (==) ServerLayout "Layout0" [ 2.314] (**) |-->Screen "Screen0" (0) [ 2.314] (**) | |-->Monitor "Monitor0" [ 2.315] (**) | |-->Device "intelgpu0" [ 2.315] (**) |-->Screen "Screen1" (1) [ 2.315] (**) | |-->Monitor "Monitor1" [ 2.315] (**) | |-->Device "intelgpu1" [ 2.315] (**) |-->Input Device "Mouse0" [ 2.315] (**) |-->Input Device "Keyboard0" [ 2.315] (==) Automatically adding devices [ 2.315] (==) Automatically enabling devices [ 2.315] (==) Automatically adding GPU devices [ 2.315] (==) Automatically binding GPU devices ([pastebin of the whole Xorg.0.log](https://pastebin.com/dhpu7awL)) and bbswitch seems to recognize and manage both video devices, albeit with some kind of problem: [ 2.272033] bbswitch: loading out-of-tree module taints kernel.
