Public bug reported:
Hi,
I'm trying to set up a light-weight but nice looking and feature-rich Ubuntu
8.04 environment.
With several applications open, including Firefox 3 (if I'm not looking at any
resource-hungry sites with Flash or heavy JavaScript), my ThinkPad Z60m
consumes around 19-24W depending on screen brightness, usage and wireless
activity, giving me around 2-2½ hours on a full charge.
In this specific scenario, according to powertop, the system wakes up
around 75 times a second when idling. Geany, being a really nice text
editor, for some reason causes exactly 10 wakeups/sec per open window
(tabs have no effect). This is considerable compared to the total
amount.
Is there any specific reason for these wakeups, and would it be possible to
reduce or completely prevent them?
In comparison, GEdit causes a constant 5 wakeups/sec, regardless of how many
windows/tabs are open and even with spell checking enabled.
I prefer Geany over GEdit for programming because of a more efficient
interface, albeit it lacks spell checking support.
