OK, so probably strictly speaking this is triggered by having multiple
adapters. 'Hybrid graphics' is by far the most common case of that
these days, though. Thanks for the note, I'll revise my blog post
(that I'm writing ATM).
I did not see such crashes on my hybrid laptop with
F24, X and
I mostly use the intel gpu, but some games run on the
nvidia-gpu with nouveau-driver.
I tried the "systemctl restart systemd-udev-trigger.service"-approach
from a "normal" terminal and from a terminal under nouveau and there
was not even a flashing of the monitor visible. I do not have a
secondary (or third ...) monitor connected, just the default laptop
