Public bug reported:
Systems with Intel HD graphics are intermittently booting into low
graphics mode. The only workaround is to log in via CTRL+ALT+F1 and
reboot the system until the display loads properly. This may take
several reboots.
Note: I am uncertain if this is a kernel bug or a xorg bug but since
this seems to only affect systems with Intel HD graphics I figured it
was a kernel bug.
