Jason C. McDonald, thank you for reporting this and helping make Ubuntu better.
In order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following: 1) The one to test is at the very top line at the top of the page (not the daily folder). 2) The release names are irrelevant. 3) The folder time stamps aren't indicative of when the kernel actually was released upstream. 4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . If testing on your main install would be inconvenient, one may: 1) Install Ubuntu to a different partition and then test this there. 2) Backup, or clone the primary install. If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists. If the mainline kernel does not fix the issue, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Also, you don't need to apport-collect further unless specifically requested to do so. It is most helpful that after testing of the latest upstream kernel is complete, you mark this report Status Confirmed. Lastly, to keep this issue relevant to upstream, please continue to test the latest mainline kernel as it becomes available. Thank you for your help. ** Tags added: bios-outdated-1.20 ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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.
