[Bug 1517048] Re: External monitors are not detected
Jose, the next step is to fully reverse commit bisect from kernel 4.2.6
to 4.3 in order to identify the last bad commit, followed immediately by
the first good one. Once this commit has been identified, then it may be
reviewed as a candidate for backporting into your release. Could you
please do this following
https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F
?
Please note, finding adjacent kernel versions is not fully commit
bisecting.
Thank you for your understanding.
