Bug ID: 416501 Summary: Compositing prevents laptop to wake up from sleep state Product: kwin Version: unspecified Platform: Other OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: compositing Assignee: kwin-bugs-n...@kde.org Reporter: francescocart...@gmail.com Target Milestone: --- SUMMARY As reported on a few forum posts in the Manjaro forum, on AMD Ryzen laptops the compositor prevents the PC to wake up from a suspend state. When suspending the machine with the compositor enabled, waking it up will result in a black screen without any possibility of user input (the PC looks totally frozen and the only way out is shutting it off with power button). A workaround so far is disabling the compositor before suspending the device, either manually or with a systemd service, but even like this it fails from time to time forcing an hard shutdown. STEPS TO REPRODUCE 1. Enable the compositor 2. Suspend the device 3. Wake up the device OBSERVED RESULT Black screen with no possibility of user input. EXPECTED RESULT Wake up the device. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Manjaro 18.1.5 KDE Plasma Version: 5.17.5 KDE Frameworks Version: 5.66 Qt Version: 5.14 ADDITIONAL INFORMATION This issue has been around since I moved to KDE in September 2019, and I've found the same issues in older forum posts since end-2018. All my researches had Ryzen CPUs as common specs, I don't know if it might affect Intel devices. -- You are receiving this mail because: You are watching all bug changes.
