Bug ID: 465399 Summary: Live image: screen goes black and will not wake up after about 10 minutes idle Classification: Plasma Product: Powerdevil Version: 5.26.90 Platform: Neon OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: plasma-b...@kde.org Reporter: fores...@sonic.net CC: m...@ratijas.tk Target Milestone: --- The KDE Neon Live image session blanks the screen after sitting idle for about ten minutes. Mouse and keyboard activity do not wake it up. STEPS TO REPRODUCE 1. Boot the KDE Neon Testing live image in a virtual machine. (I used virt-manager/libvirt.) 2. Let it sit idle for about ten minutes, until the screen turns black. 3. Move the mouse or press keyboard buttons. OBSERVED RESULT The screen remains black. EXPECTED RESULT The screen should have awakened. SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Neon Testing Edition neon-testing-20230206-1112.iso Operating System: KDE neon Testing Edition KDE Plasma Version: 5.26.90 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 Kernel Version: 5.15.0-58-generic (64-bit) Graphics Platform: X11 Processors: 2 × Intel Xeon E3-12xx v2 (Ivy Bridge, IBRS) Memory: 3.8 GiB of RAM Graphics Processor: llvmpipe Manufacturer: QEMU Product Name: Standard PC (Q35 + ICH9, 2009) System Version: pc-q35-5.2 ADDITIONAL INFORMATION The OS is still running.
