Comment 23 for bug 1822854

It might be a kernel bug related to get/iommu which I had enabled to test with accelerated graphics in VMs. I think that the Kabylake are not really supported for that yet. I turned those off now.

Switching desktop environments would be hard. I can't work in a different de! My assumption was that maybe it was gnome powering down the monitor because it wrongly thought I was inactive or something.

IIRC, the same problem occurs in Wayland sessions, so it's at least not an X bug.
