After upgrading from 4.4.0-93 -> 4.4.0-96 (the default update using the Software Updater yesterday), I get the following:
1. A menu:
The system is running in low-graphics mode
Your screen, graphics card and input device settings could not be detected correctly. You will need to configure these yourself.
2. I press OK and obtain a new one offering choices:
What would you like to do?
Try running with default graphical mode
Reconfigure graphics
Troubleshoot the error
Exit to console login
At this point I cannot use the mouse/touchpad/keyboard at all to make a choice or press ENTER to continue. After pressing ESC I get the black screen with boot messages:
/dev/sda2: clean xxxx/xxxx files, xxx/xxx blocks
. bbswitch: No suitable _DSM call found.
. bbswitch: No suitable _DSM call found.
. bbswitch: No suitable _DSM call found.
. bbswitch: No suitable _DSM call found.
. bbswitch: No suitable _DSM call found.
............... indefinitely .......
Then I press the switch button to reboot.
I cannot find a way out, so I reverted to kernel 4.4.0-93 and everything seems back to normal.
================================================== ==============
A reminder to all panicked visitors on how to revert to the previous kernel:
. reboot
. If the GRUB menu does not show (like in my case, I only have Ubuntu), hit ESC once
. Choose Advanced Options for Ubuntu and from the menu pick the kernel that works for you (in my case 4.4.0-93)
After you boot, uninstall the unwanted kernel and update the grub menu: (everything after > is a command line)
> dpkg --list | grep linux-image (select the packages relevant for you and add them to the next line instead of my *4.4.0-96* packages)
> apt-get remove linux-image-extra-4.4.0-96-generic linux-headers-4.4.0-96 linux-image-4.4.0-96-generic linux-signed-image-4.4.0-96-generic
> update-grub

Information on my laptop:
DELL Latitude 3550
Ubuntu 16.04.3 LTS
kernel that works: Linux 4.4.0-93-generic #116-Ubuntu SMP Fri Aug 11 21:17:51 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
The output of the commands lshw , lspci , lsusb, lsmod is attached to the corresponding files.
(Note: they are created on the 4.4.0-93 working environment. The second monitor is irrelevant, the problem persists when the laptop is not attached to anything - mouse,keyboard,monitor, ...)
