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.
