In the "Red Hat QXL controller Properties" dialog:
- on the General tab, Manufacturer is "Red Hat, Inc."
- on the Driver tab, both the "Driver Provider" and the "Digital Signer"
fields are "Red Hat, Inc."
This driver comes from "qxlwddm-0.1-12" (buildID=449635), in Brew.
In retrospect it looks like this driver was meant for Windows 8 only,
but it happened to install under, and work OK for, Windows 10 too.

Yes, it does. (Double-checked it with "confirm-SecureBootUEFI" in
PowerShell.)

I'm happy to try other driver versions. Hopefully Windows 10 will
actually see them as upgrading the currently installed driver. (Or
should I uninstall first?)
This is the latest release
