Public bug reported:

If I try to switch to intel mode on my Zenbook Pro UX550 and then reboot, I end 
up without a graphical session. GDM does not start even if it seems to be 
trying to for many times. I see a systemd message that the dGPU could not be 
switched off. Also, I get a flickery screen on TTYs until GDM gives up with the 
screen alternating between the TTY and the systemd textual log. Once that stops 
flashing I manage to prime-select nvidia and reboot cleanly. This is certianly 
better than before the update but it does not fix the situation fully. I am 
using bionic with all updates applied.
