I did not see such crashes on my hybrid laptop with F24, X and
gnome-shell.
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
screen.
OK, that's the second report of an unaffected hybrid system (cmurf said
the same thing).
So basically we can say that at least several systems with multiple
adapters are affected, and no-one has yet reported a system with a
single adapter being affected so far as I can tell. But not *all*
multiple adapter systems are affected. We don't know what the
difference is yet. Still, safest thing is just to assume that if you
have a multiple adapter system you may be affected.
