Package: sleepd
Version: 1.2.16
Severity: wishlist
Several times sleepd has annoyed me by suspending my notebook just as
I started to use it. The scenario is as follows:
- plug into AC power
- spend an hour doing something on the other side of the room
- come to get the machine, unplug it
- watch it go into suspension
Of course, I figured out a workaround - to hit any key before
unplugging it.
However, my mental model for sleepd is "suspend if nothing has
happened for the last N minutes", and it seems that gaining or losing
AC power should count as "something has happened". Here's a patch for
one possible implementation.
