    Default Laptop powerstate issue (beta 1)

    Hi,

    I use Zimbra Desktop on my laptop. When running zdesktop server, which I'd really like to do all of the time, my CPU about 200 types a second. 49% of those wakeups are:

    42.8% (120.5) java : futex_wait (hrtimer_wakeup)

    It doesn't sound like much, but I've lost a bit of battery life. Is there a wake to keep the wakeups a bit lower?

    Thanks,
    Gerald

    ps: I use powertop to test my wakeups and estimated battery usage.

    Which platform are you on? And how does it compare to other applications you are running? Thanks!

    Duh, sorry. I should know better than that.

    This was under Kubuntu 7.10, a fresh install. The next competitor was waking up 8.2 % of the time (the xserver). The rest I can't recall.

    I'll see if I can compile a new kernel for my Sabayon install and let you know what's going on there.
