Graham PerrinPlasma: high CPU usage whilst the screen is locked
<https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=293820>
Can anyone suggest a workaround?
Tom@grahamperrin This happens in Linux too. I don't think it's tied to FreeBSD.
@pertho thanks, which distro? Etc.
No problem here with Kubuntu 25.10.
@grahamperrin Void Linux
@pertho I double checked, it seems that Kubuntu uses less CPU when the screen is locked.
If you can discover why your Void uses more (not less), maybe you'll find a report of a bug that's not yet fixed in whatever versions of stuff that you use.
I did check for an upstream bug before making the report in Bugzilla for FreeBSD. I suspect that 293820 is a duplicate of 293368 <https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=293368>, for which there might be an errata notice (EN).
Whilst a workaround for 293820 will be nice, it doesn't bug me personally; the affected machines are for test purposes only.
@pertho whilst logged in with the screen locked, the issue seems to be with (or affecting) kscreenlocker_greet – installed by security/plasma6-kscreenlocker.
I wonder why I didn't notice this when I made the bug report.
@grahamperrin Wow. Wonder if it's stuck in some kind of endless loop? 🤔
