My screen energy saving is set to switch off after 10 minutes and usually works. Every once and a while it just stops working. How can I restart (reset) it without logging off or rebooting? Changing the time value in “settings” and applying the change doesn’t restart or reinitialize the process.
I have similar problem with latest update of KDE NEON ( Plasma 5.27.10 / Framework 5.114.0 / Qt 5.15.12 ) with Wayland.
When my desktop switch off after 10 minutes, everything is OK with my primary screen, but the secondary one goes to black (but not to energy saving since it is still backlit), and it never wake up until I unplug/plug the power cable.
Both of those don’t sound great, sorry that this is happening to you.
I only got into Plasma development with Plasma 6 and am not well prepared to analyze/fix 5.27. (Also not sure if more 5.27 releases are still going to happen.) Please speak up if it’s still broken on 6.0 once you upgrade. Or file a bug for 5.27 and hope that someone will still look into it before you make the switch.
I have the same problem with KDEneon since the last update.
It doesn’t matter whether I use X11 or Wayland.
I don’t have this with a test installation of Kubuntu.
The KDEneon testing version also works, but has other small problems.
Does anyone know when the KDEneon testing will be released as final?
Would someone who’s experiencing this problem be willing to file a bug on bugs.kde.org, assuming one doesn’t exist already? It seems reproducible enough, so with the right pair of developer eyes, hopefully it can be fixed.
