I'm not sure why you think it's only a security update, when it didn't
specify what the "other fixes" were. As was previously advised to you in
https://help.ubuntu.com/community/BIOSUpdate , not all BIOS fixes are
documented in the change log, tested to your specific problem under the
same operating system, or tested under your operating system at all.
Unfortunately in this case, it didn't improve the situation.

Despite this, could you please advise which nvidia driver package
precisely you were using when this worked in Trusty?

Title:
  Black screen after "prime-select nvidia" and restart of lightdm/reboot

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  I'm using a Lenovo laptop with an intel/nvidia Optimus compatible graphics solution. While being able to use prime-select to switch between those cards with Ubuntu 14.X and official nvidia drivers it stopped working when switching to ubuntu 15.04 and newer drivers. I'm not sure when the problem first arises, but I'm stucking with it for almost 5 month.
  In the meanwhile I stumbled upon errors in xorg.log pointing to insufficient permissions related to DRM and intel driver. I switched to a newer kernel 4.1.x and the xorg.log error had gone, but the general problem remains.
  A month ago I switched to a 15.10 daily build to test if the bug still exists there. I did a fresh install but the problem is still the same.
