439315 2021-06-29 21:27:59 +0000 Power management inhibition cannot be disabled 2021-07-30 16:44:04 +0000 1 1 10 Unmaintained Powerdevil general 5.22.2 Neon Linux RESOLVED DUPLICATE 433675 NOR normal --- 0 popov895 plasma-bugs-null nate popov895 storagebin95 0 oldest_to_newest 2044306 0 popov895 2021-06-29 21:27:59 +0000 SUMMARY In the "Battery and Brightness" applet, after unchecking the "Inhibit automatic sleep and screen locking" checkbox, the power management inhibition remains active. Only restarting plasmashell resets all inhibitions. I found, that after unchecking the above checkbox, PlasmaCore.DataSource for the "powermanagement" engine still contains the "plasmashell" inhibition (https://invent.kde.org/plasma/plasma-workspace/-/blob/master/applets/batterymonitor/package/contents/ui/logic.js#L77). STEPS TO REPRODUCE 1. Open "System Settings" 2. Go to "Power Management" > "Energy Saving" 3. Check "Dim screen" checkbox and set delay to 1 minute 4. Open "Battery and Brightness" applet 5. Check the "Inhibit automatic sleep and screen locking" checkbox to enable power management inhibition and wait a few seconds (it takes a few seconds to turn it on) 6. Uncheck the above checkbox to disable power management inhibition 7. Wait 1 minute until the screen goes dim OBSERVED RESULT The screen doesn't dim. EXPECTED RESULT The screen dims.

Once you uncheck the setting, you cannot re-enable automatic sleep and screen locking by simply re-checking the setting. You must also restart the plasma shell by logging out and logging back in.
