Most days, when this occurs, I just open up my lid and/or tap the power button and it wakes up, and I close the lid again once it is awake.
In my particular case, when I wake up my laptop, my CableMatters 201055-BLK thunderbolt port replicator sends my dual display 1440p monitors into 1080p briefly as my 2160p laptop panel comes to life; I close the lid and everything is back to normal on my dual 1440p panels. All to say, I can wake up my system by opening the lid and/or hitting the power button. If I had to bet, I'd say the thunderbolt port replicator implementation is part of the problem, as I see quirks with the various gadget drivers running across it regularily that, thankfully, do not impact me as they are not in my usual use case: a) Using PD via the replicator sometimes requires re-plug before laptop detects power and I don't think the charging is quite as fast, possibly not ramping up the the Max Dell power rates for the port b) Moving my Logitech keyboard/mouse dongle to the replicator from a local port results in sometimes getting keyboard timeouts (even though the mouse is fine over same dongle) c) Opening the lid, the displays do not always switch modes correctly to the 3 screens (2 x 1440p and 1 x 2160p panel) and sometimes as bad as what appears to be a useless 800x600 section of the actual desktop shown on one of the external displays, closing the lid always returns to proper dual 1440p These are the devices that enumerate on my replicator, with 04b4:f649 being the main one driving the Displays and thunderbolt and the FE and USB devices attached.
