Just a heads up - yes, I'm working on the full commit bisect. Good news, I know it's between 4.4.0.53 and 4.4.0.54 (the glitch is present in that version) - bad news, before I could do the next step in the bisect, I accidentally switched my ABI (I have two compilers). Now it is complaining about the ABI change, so I'm going to have to start over more or less.
I'll keep you posted. -- 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.
