Public bug reported:

If I connect my monitor to my computer with a VGA cable, I have to stop
at the grub menu and add 'nomodeset' to the kernel options with all the
4.4.0-* kernels.

If I do not add 'nomodeset' to the kernel options, my monitor goes
blank, complains of no video signal, then goes to sleep as soon as the
kernel attempts to enable mode setting.

Turning the monitor off and back on does not help, unplugging the VGA
cable and connecting the DVI cable does not help. I have to hit
'Ctrl'+'Alt'+'Del' and wait for the computer to restart or hit the power
button and wait for the computer to shutdown.

If I connect the monitor to the computer with a DVI cable, I do not have
to add 'nomodeset' to the kernel options, everything works as expected.

I do not have the option for HDMI on the monitor currently attached.
Will see if I can get that tested either with another monitor or DVI to
HDMI adapter.
