Multi-Monitor Setup

I have two 1080p monitors and my laptop. After installing optimus-manager I can no longer use my 2 other monitors, even when switching to nvidia mode. One is connected via a docking port and another via HDMI, both work perfectly fine on Windows and use to work when I used only dedicated graphics on Arch. Neither of my external monitors are detected when I use xrandr (at least in hybrid mode) but other devices connected to my docking port still work. Is there anything I can do or that can be done to solve this?

System info:

• Switching method: Nvidia drive built-in power management
• Using: optimus-manager 1.2.2-2.2
• Operating System: 5.5.2-arch-1
• Desktop Environment: KDE Plasma 5.17.5
• Login Manager: SDDM
• CPU: Core i7-9850h
• GPU: Quadro RTX 3000

FYI - the latest Nvidia driver 450.36.06 (still on beta/only packaged on CUDA: https://bugs.archlinux.org/task/67014) has the sink functionality and allows to use the Nvidia-plugged outputs on my Thinkpad P1 from hybrid mode, as sinks rendered by Intel, out of the box 🎉

In the default sink output configuration I’m still experiencing issues. Performance has improved but it isn’t nearly as close as it is to when I’m Running in Reverse PRIME. I’ve stuck to using Reverse Prime for now, the battery life sucks from always keeping the NVIDIA GPU on but I have an outlet almost everywhere I go so it’s bearable.
