Description

Lenovo E93Z AIO with Nvidia Geforce GT720A and Intel gen4 graphics

On boot I get various error messages from the Nouveau driver, here is my dmesg output when I grep for nouveau

nouveau 0000:01:00.0: enabling device (0000 -> 0003)

The above is with the 4.14.8-300.fc27.x86_64 kernel (Fedora 27)

So.. No volting, MMIO read error and TMDS table error.
