** Description changed: - For reference this problem is very similar to #1577074 - - However, the laptop is simply booting to a black screen on 16.04, the - backlight is on but there is no display. Sound is working so I can hear - the ubuntu logon noise and can SSH from another machine. + My laptop (HP Pavilion 15-ab141na) is simply booting to a black screen + on 16.04, the backlight is on but there is no display. Sound is working + so I can hear the ubuntu logon noise and can SSH from another machine. During boot the screen on the laptop looks as if it is flashing off and on trying to set modes or something similar, I'm guessing this is the looping shown in the output below Errors from dmesg are as follows: [ 40.744416] [drm:amdgpu_resume [amdgpu]] *ERROR* resume 4 failed -2 [ 40.744453] [drm:amdgpu_resume_kms [amdgpu]] *ERROR* amdgpu_resume failed (-2).
