Update
Main PC:
Arch Linux + KDE Plasma (Wayland)
Dual Xeon E5-2689 — 16 cores / 32 threads
128GB RAM
Intel Arc B580 (upgraded from GTX 1070)
Removed secondary GPU due to issues
Displays:
32" 1080p centre monitor
24" monitor
3x 22" monitors(one of is used with windows laptop)
Also running:
Ryzen 3700U laptop with 16GB RAM
Galaxy Tab A 2018 tablet
Using Deskflow to share keyboard/mouse between my Linux desktop and Windows laptop. The tablet is mainly used for monitoring, YouTube, and extra screen space.
The only Windows apps I still use are Creality Slicer and FrostWire since they don't work properly on Arch. Everything else I need is done on Linux.
I also use USB/IP and Syncthing across both systems for sharing devices and keeping everything synced.
Still trying to figure out a proper way to use the tablet as a secondary display with keyboard/mouse input.
