Dual monitors not reconised through Lenovo USB-C Gen 2 Dock

Hi all,

I have a brand new install of Arch on a Lenovo Thinkpad X1 Extreme Gen 2 and all more or less works perfectly except for the dual monitor set up. The laptop has an Nvidia GTX1650 card and I have installed the drivers via pacman for nvidia and nvidia-utils. I have also followed the procedure for Nvidia Optimus here but that broke the system entirely.

I've read several articles relating to display link drivers and have also installed this one. Im not actually even sure I'm heading in the right direction here as both monitors are plugged into the docking station. I had the exact same set up running Kubuntu 18.04LTS and everything worked perfectly.

Currently all other peripherals on the dock are working. There is a usb mouse and keyboard, ethernet, webcam and headset with mic - all working perfectly.

lspci | grep -E "VGA|3D"

00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 630 (Mobile)
01:00.0 VGA compatible controller: NVIDIA Corporation TU117M [GeForce GTX 1650 Mobile / Max-Q] (rev a1)

lspci -k

        Kernel modules: i915

        Kernel driver in use: nvidia

Any help would be appreciated.

Thanks

EDIT: After much research I have solved this issue by installing the optimus-manager and optimus-manager-qt tools from this github repo
