So…As I installed KDE Neon recently, it worked and autosuspended perfectly after 15min, which is what’s set on Power Management settings. However, I’ve noticed after installing and configuring all the rest of the apps, it’s no longer the case. I mean, it DOES suspend if I manually click the Suspend in the start menu, or if I hit the suspend key from my keyboard. But it won’t do it on its own.

I initially suspected SMPlayer, which in the Ubuntu 24.04 repos has a long standing issue about this (will suspend when playback stopped, but not when paused). But after installing the newest flatpak…and even with SMPlayer closed, it’s still not suspending. What else could be blocking Power Management from suspending my PC? How can I troubleshoot this?

Thanks!
