Public bug reported:
Binary package hint: powertop
Powertop seems to be a very useful tool for analyzing power usage and
suggesting easy system tweaks to decrease power use. However, it is a
little dangerous in that root-level system tweaks are only a hot-key
away, with no real explanation of what's going on.
I think it would be useful if powertop also offered a short explanation of what
each of the suggested tweaks would do, and give any specific warning. Some
examples:
-- I saw one suggestion on my system that recommended that I disable HAL
polling my cdrom. That's fine for now, but what if I insert a CD later? Will
I be able to use the CD? Will this setting revert at reboot?
-- There was another suggestion that I increase the dirty writeback interval
from 0.30 seconds to 15 seconds. This should send a warning to the user, that
this can cause high risk of data corruption in a power outage.
** Affects: powertop (Ubuntu)
