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 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. I've tried re-compiling my graphics drivers, but this did not resolve the issue Reproducible: Always Steps to Reproduce: 1.Upgrade to kde-plasma/plasma-meta-5.27.4 on a Lenovo ThinkPad P52 using a Hybrid Graphics setup Actual Results: The external monitors are no longer detected Expected Results: Detected external monitors emerge --info Portage 3.0.44 (python 3.10.10-final-0,

If you can clearly isolate this problem to the KDE Plasma 5.27.4 update and not some nvidia-drivers or kernel update at the same time, then please file an upstream bug at bugs.kde.org (after searching for existing bugs).
Thanks, I'll do so. I've only updated Qt and KDE today, nothing else so far. It was working fine this morning, so it has to be QT (unlikely as it was an upgrade to 5.15.9) or KDE.
Reported upstream at KDE.
Feel free to add a link here to your upstream bug so we can keep an eye on it.
