I hope this helps. I was trying to figure out why the resolution hiccups
when I install linux-
image-4.2.0-30-generic_4.2.0-30.35+lp1548587~kamal2_amd64.deb but what I
think I have demonstrated is that the original bug (GUI not displaying)
is due to the package: linux-image-extra-4.2.0-30-generic
Step #1
When I confirmed Kamal's kernel image, I had installed it into VMs where I had
previously upgraded to 4.2.0-30 but subsequently uninstalled both
linux-image-4.2.0-30 and linux-image-extra-4.2.0-30-generic like so:
sudo apt-get --purge removelinux-image-4.2.0-30
linux-image-extra-4.2.0-30-generic
I was running linux-image-4.2.0-30-generic_4.2.0-30.35+lp1548587~kamal2
along side linux-image-extra-4.2.0-27-generic and that fixed the
original bug with the GUI not displaying, but caused an incidental bug
where the VMWare window was resized to 8000x3200.
Step #2
I only installed half of Kamal's fix, so this time I installed a new VM with
15.10, upgraded it to 4.2.0-30, verified GUI not displaying, and then installed
both the linux-image and linux-image-extra from Kamal's fix. Sure enough, the
GUI displaying bug was fixed and the resolution did not tweak out like when
there was a version mismatch.
Step #3
This time I installed a new VM with 15.10, upgraded to 4.20-30, verified the
bug, and then only installed Kamal's image fix (not the extras package). That
means I was running: linux-image-4.2.0-30-generic_4.2.0-30.35+lp1548587~kamal2
with linux-image-extra-4.2.0-30-generic. This time I still had the GUI not
displaying issue - but with Kamal's new kernel image. Now I am starting to
think the issue is with the linux-image-extra-4.2.0-30-generic . I advanced it
to Kamal's version
(linux-image-extra-4.2.0-30-generic_4.2.0-30.35+lp1548587~kamal2) and it
worked! I rolled it all the way back to linux-image-extra-4.2.0-16-generic and
it worked! Its only when the package is linux-image-extra-4.2.0-30-generic that
it doesn't work. Again, I noticed that the resolution issue only happens when
the linux-image and linux-image-extra versions are mismatched.
Step #4
To be as anal as possible, I setup a new VM and decided to try
linux-image-4.2.0-30-generic with a rolled back linux-image-extra. Viola, it
worked! However, due to version mismatch, the resolution issue appeared.
TL;DR (Conclusions)
linux-image-4.2.0-30-generic works with linux-image-extra-4.2.0-27-generic and
linux-image-extra-4.2.0-16-generic but not with
linux-image-extra-4.2.0-30-generic
The resolution issue is really a non issue because it only happens when
I use packages from different versions.
Kamal, maybe you don't want to undo the changes made in the linux-image
package between 4.2.0-27 and 4.2.0-30 if the bug can be completely
localized to linux-image-extra.

Title:
Ubuntu 15.10 VMWare guest won't show UI after upgrading to 4.2.0-30
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Wily:
In Progress
Bug description:
I installed a fresh copy of Ubuntu 15.10 64-bit as a guest VM in
VMWare Workstation 12.1.0.
After installation, I am able to log into the system. I then ran the
updater application to install the latest updates.
After installing the updates and restarting, the system no longer
shows any UI after booting. I am now faced with a black screen and a
dash that does not blink. The system also does not respond to any
inputs.
I was able to get back into my system by holding shift to show the
GRUB menu and boot using the 4.2.16 kernel.
