Commit 507135ee settings: Reduce inactivity times to reasonable values
It seems as if before Commit 507135ee if auto suspend on time was used the max time before suspend was 360 minutes. it seems to me that an optional block of time setting should have a descent range of time to fit a larger set of users. A user not needing 360 minutes isn't require to make a setting that is larger than they need. however, if a very small block of time is programed a number of users will have issues.
Users like myself who needs 120 minutes before the computer goes into sleep mode. is kind of screwed.
Note I've used the "Settings Editor" to change "inactive-on-ac" to a value=120 that results in my computer suspending after 120 minutes.
However. In the Power Manager > System > inactive time slider which shows 60 minutes is moved it converts back to 60 minutes and requires resetting 120 minutes in the settings editor.
thank you
