Bug ID: 201505
Summary: Resume from suspend does not power up the display
Product: Drivers
Version: 2.5
Kernel Version: 4.19
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - non Intel)
Assignee: [email protected]
Reporter: [email protected]
Regression: No
Resuming the machine from suspend-to-ram no longer restores power to the
display attached to an AMD GPU in Linux 4.19 (assuming the display has switched
to sleep mode by itself because the computer hasn't been in use for a while).
If the display is still powered on when resuming, it ends up blank.
Linux 4.18 did not contain this bug.
Kernel: 4.19
Module: amdgpu
GPU: R9 390
