SUMMARY
***
I upgraded to kde-plasma/plasma-meta-5.27.4 today and after the upgrade my
external monitors connected to my dGPU stopped working. They were working fine
on the previous kde-plasma/plasma-meta (5.26.x) release. I'm using a Lenovo
ThinkPad P52 with hybrid graphics where the internal iGPU (Intel i915) is
connected to the internal monitor and the external ports are connected to the
dGPU (nvidia) via thunderbolt (MUXed system). I've tried re-compiling my
graphics drivers, but this did not resolve the issue. No other packages besides
kde-plasma and the kde-framework packages were updated.
