doh, that's a core2 thing. See
cat /sys/devices/virtual/thermal/thermal_zone*/temp
although that is the package temp, not the core temps. I see 52C on a
lenovo here.
The suggestion is extremely valid. Without it programs will default to
polling because there is no other method to monitor files and folders.
Any reason why it's not the default?
from MeeGo Trunk, kernel package, config-generic:
# CONFIG_INOTIFY=y
# CONFIG_INOTIFY_USER=y
You're not running MeeGo now, are you? The kernel version string suggests
you run something else :P
My Lenovo s10-3t netbook is running MeeGo "1.2" alpha where
Linux meegolem 2.6.37-7.28 #1 SMP PREEMPT Tue Feb 22 03:55:51 UTC 2011
i686 i686 i386 GNU/Linux == meego-netbook-ia32-1.1.90.4.20110222.2.img
Why would I be posting stuff to the MeeGo lists about a different OS?
my bad, misread something - ignore that :)
Other than my recent gentle prodding to take a look at stability and
UX of Fedora15/Gnome3 on the same netbook in order to remain
competitive:
http://lists.meego.com/pipermail/meego-community/2011-March/003628.html
ANd of course my "meego" looks a little different than most people's
since I am now successfully using Fedora14/RPMFusion/PlanetCCRMA RPMs
in MeeGo 1.2 (
http://lists.meego.com/pipermail/meego-community/2011-March/003628.html
and the last half of

graphics interrupts. Seems like something is requesting interrupts from the
gpu.
Xorg is always spinning just a little even when I'm interacting w/ the
netbook over SSH from desktop -- it's not like there's a clock
updating it's second hand or anything else that's moving on the
screen, but you see
387 npm 20 0 17852 8544 5112 S 0.3 1.0 0:08.05 Xorg
And also you see stuff like this all the time -- as if the touch panel
is active even when
I'm not using the netbook's display or touchscreen:
100.0% USB device 3-1 : Cando 10.1 Multi Touch Panel with Controller
(Cando Corporation)
apart from that, the suggestion was recently changed to ask for
CONFIG_INOTIFY_USER instead of CONFIG_INOTIFY, since that option no longer
exists in the kernel config. Check if your kernel has this option enabled
instead. This will hopefully make it into a new release soon.
I'm looking forward to the a final release of 1.2 with all the bugs
fixed and the performance tuned to the netbook.

(3) "Disable Ethernet Wake-On-Lan with the following command:
ethtool -s eth0 wol d
Wake-on-Lan keeps the phy active, even when the system is turned off."
(doesn't seem to do anything, prob because 'ethtool' not installed)
internally, powertop calls the ethtool ioctl to change WoL. It does not
need to have the ethtool binary installed. The suggestion shows how `a
normal user` can do it themselves, but, pushing the button in powertop
will work.

Note that on reboot, you need to re-run all the powertop suggestions
again. They're not sticky. Why aren't these settings run out of
/etc/init.d/??
WoL is set according to the BIOS. You need to change the setting in the
BIOS to disable WoL, or work with your BIOS vendor to get an option in
your BIOS to allow it to be disabled.
As for SATA, I'm not sure.
We can't blanket enable PM for USB devices, as, chances are that you
will no longer be able to control your device. And that would be bad.
