I can reproduce this consistently by using 'xset -display :0 dpms force standby' and waiting about one minute. Running 'xrandr --output DisplayPort-2 --auto' restores the display to its normal native resolution. The system log shows the following error: [drm] enabling link 2 failed: 15 [drm:dm_restore_drm_connector_state [amdgpu]] *ERROR* Restoring old state failed with -22 Stack trace: <a href="https://pastebin.com/yguN5NUk">https://pastebin.com/yguN5NUk</a> System specification: OS: Arch linux 5.3.1-arch1-1-ARCH GPU: AMD Radeon RX 590 using AMDGPU-Pro DE: KDE Plasma 5.16.5</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
