Bug ID: 109068 Summary: Raven Ridge: backlight is off after suspend Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: samantham@posteo.net
This is an issue on amd-staging-drm-next but not on 4.19.7. I have not tested other kernels. The issue is that if you put the system in suspend and wake it up again, the backlight is off. On 4.19 when you resume from suspend the backlight resumes the same level it was when you put it into suspend.

In addition, this is what happens to the levels of "brightness" and "actual_brightness" before and after sleep on amd-staging-drm-next:
Before sleep: actual_brightness: 12141 brightness: 102 After sleep: actual_brightness: 0 brightness: 102
On 4.20-rc5 or 4.19 actual_brightness is not at 0 after resume from suspend.
