ok, SUPER interesting -- when I force the intel profile to be PRIME,
then I can safely boot with the enclosure attached(!), the systems gets
through gdm, and I can login no problem.
I suspect there is a driver problem we are chasing, and PRIME was just
selecting the NVIDIA GPU for some reason and flailing ..'
Hmm running into a bit of a snag :
beadon@semiauto:~$ sudo nvidia-settings
[sudo] password for beadon:

Performing an strace I am seeing that the gnome-shell is **very** frequently
hitting :
EAGAIN (Resource temporarily unavailable)
It's not clear to me what is causing this. strace on the 33 threads
included for reference. To show different behaviors, clicks, movement
of windows, typing in a terminal, as running glxgears to show(get) the
refresh rate of 5 frames per second.
Is there some kind of heavy CPU-based communication happening for
gnome-shell ? I am seeing the CPU usage spike to 90+% when simple
movements are done on screen. However, the nvidia-smi tools reports
that it truly is attached to the right GPU, the PID is correct.
Please see the strace for further information.
