Jason C. McDonald, the next step is to fully commit bisect from kernel 4.4.0.53 to 4.4.0-57 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?
Please note, finding adjacent kernel versions, or providing a commit from a kernel version bisect is not fully commit bisecting. Also, the kernel release names are irrelevant for the purposes of bisecting. It is most helpful that after the fix commit (not kernel version) has been identified, you then mark this report Status Confirmed. Thank you for your help. ** Tags added: kernel-bug-exists-upstream kernel-bug-exists- upstream-4.10-rc2 needs-bisect regression-update -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1652354 Title: Internal laptop display stops working in 4.4.0-57-generic Status in linux package in Ubuntu: Incomplete Bug description: I have a Toshiba Satellite P745D w/ AMD graphics, and I'm running the open source Radeon driver. I can use the internal and/or an external VGA monitor just fine in 4.4.0.53-generic and prior. However, upon updating to 4.4.0-57-generic, the internal monitor shuts off after GRUB and will not display anything. Setting NOMODESET in GRUB does not resolve the issue - I had to reboot into 4.4.0-53 to see anything on the internal laptop monitor.
