SUMMARY under power management, setting suspend option to sleep results in a hard lockup and PC will not wake up. STEPS TO REPRODUCE 1. go to settings > power management > suspend options > sleep 2. allow system to fall asleep with default sleep.config 3. try to wake system after suspend (via USB or power button) OBSERVED RESULT system does not wake or respond to anything other than a hard reset with the power button (holding it down for 5sec) EXPECTED RESULT system resumes to the exact state it was in before suspend. SOFTWARE/OS VERSIONS Operating System: Kubuntu 24.10 KDE Plasma Version: 6.1.5 KDE Frameworks Version: 6.6.0 Qt Version: 6.6.2 Kernel Version: 6.11.0-13-generic (64-bit) Graphics Platform: X11 Processors: 28 × Intel® Core™ i7-14700K Memory: 62.6 GiB of RAM Graphics Processor: AMD Radeon RX 6800 Manufacturer: Micro-Star International Co., Ltd. Product Name: MS-7D27 System Version: 1.0 ADDITIONAL INFORMATION investigating the `/etc/systemd/sleep.conf` options and testing various settings by uncommenting lines in the file, i have discovered that the the "freeze" state to be the root of the problem. `cat /sys/power/state` shows the order of operations with `freeze mem disk`, but freeze does not work on my system, only mem and disk so setting the sleep.conf as shown avoids the "freeze" state ``` [Sleep] AllowSuspend=yes AllowHibernation=yes AllowSuspendThenHibernate=yes AllowHybridSleep=no SuspendState=mem disk HibernateMode=platform shutdown MemorySleepMode=deep HibernateDelaySec=60 #SuspendEstimationSec=60min ```
Thank you for the bug report! However Plasma 6.1.5 is no longer eligible for support or maintenance from KDE; supported versions are 5.27. (LTS), and 6.2 (non-LTS) or newer. Please upgrade to a supported version as soon as your distribution makes it available to you. Plasma is a fast-moving project, and bugs in one version are often fixed in the next one. If you need support for Plasma 6.1.5, please contact your distribution, who bears the responsibility of providing support for older releases that are no longer supported by KDE. If you can reproduce the issue after upgrading to a supported version, feel free to re-open this bug report.
