Public bug reported:
I have a Toshiba Satellite P745D w/ AMD graphics, and I'm running the
open source Radeon driver. I can use the internal and/or an external VGA
monitor just fine in 4.4.0.53-generic and prior. However, upon updating
to 4.4.0-57-generic, the internal monitor shuts off after GRUB and will
not display anything. Setting NOMODESET in GRUB does not resolve the
issue - I had to reboot into 4.4.0-53 to see anything on the internal
laptop monitor.
