Public bug reported: After the screen turns off (for inactivity, screen lock, etc.), mouse or keyboard input won't bring it back. When I come back to the computer to resume my work, I have to wake the system up, and press the power button on the monitor. If I don't manually bring the monitor back on, the system will resume and the screen will remain off.
I believe this is a regression, because this cannot be reproduced in distributions as old as Debian Stretch 9. Any distribution newer than Debian causes this problem. This is also not reproducible on Windows 10. It's worth mentioning that this desktop runs the RX 560 AMD graphics card. Also, this is my monitor: https://www.lg.com/in/monitors/lg-22MP58VQ ProblemType: Bug DistroRelease: Ubuntu 19.04 Package: linux-image-5.0.0-15-generic 5.0.0-15.16 ProcVersionSignature: Ubuntu 5.0.0-15.16-generic 5.0.6 Uname: Linux 5.0.0-15-generic x86_64 ApportVersion: 2.20.10-0ubuntu27 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: dsilva 1883 F.... pulseaudio /dev/snd/controlC1: dsilva 1883 F.... pulseaudio CurrentDesktop: ubuntu:GNOME Date: Mon May 27 22:45:13 2019 InstallationDate: Installed on 2019-05-26 (2 days ago) InstallationMedia: Ubuntu 19.04 "Disco Dingo" - Release amd64 (20190416) IwConfig: enp2s0 no wireless extensions. lo no wireless extensions.
