Public bug reported:
I just upgraded to bionic from artful and the kernel's graphics stack
seems to be hosed. I can get text consoles, but neither plymouth nor
Wayland GDM sessions work.
X11 sessions do work however, e.g. by disabling Wayland for GDM3 in
custom.conf or running startx from the console, however to get to that
point you need to boot into a recovery session from the bootloader to
avoid invoking the bootsplash, then proceed to boot normally from the
recovery menu.
If I boot into the 4.13 kernel I had leftover from artful, everything
works fine.
This is on a MacBookPro12,1 with an i7-5557U and Intel Iris 6100
(Broadwell GT3) integrated GPU.
