Workaround identified: The issue can be temporarily resolved by forcing correct display mapping:
xrandr --output DVI-D-1 --off xrandr --output HDMI-A-0 --primary --mode 1920x1080 This indicates that the kernel/DRM stack restores an incorrect display state after resume. EDID and HDMI link are confirmed to be working. This is likely an issue in atomic modeset or connector mapping during resume. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2142389 Title: amdgpu (R9 380) fails to resume from suspend (deep sleep) – black screen, requires hard reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2142389/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
