Indeed the driver is loaded, however in the very first pastebin log,
this module wasn't loaded (ref. https://pastebin.com/a9an6Y7M).
I have missed the second log file link/attachment (attachment-0001.ksh).
Looking at it confirms modesetting's successful loading.
Can you provide more details about the external screen(s) you are trying
to attach e.g. make, model, resolution etc.?
Best
