For meaning about cX state see here: http://www.lesswatts.org/projects/powertop/powertop.php thanks! You didn't give enough information so we will need to check the basis : - which cpufreq driver and governor are you using in both cases (check cpufreq-info) - what processes does powertop show as causes for wakeups ? - what processes does top show in term of cpu usage ? Here is what I got in the last few minutes when i was writing this : C4 mwait 3.4ms (92.5%) 800 Mhz98.0% Wakeups-from-idle per second : 279.4interval: 10.0s I have a core 2 duo with acpi-cpufreq loaded and conservative governor. $ grep cpufreq /etc/rc.conf MODULES=(acpi-cpufreq) DAEMONS=(syslog-ng net-profiles crond dbus hal alsa cpufreq storage-fixup) $ grep governor /etc/conf.d/cpufreq # valid governors: governor="conservative" They may just not have cpu-freq-utils installed maybe? I'm using laptop-mode-tools with compiz and GNOME running (but not doing anything) and it's saying 99.2% C4, 0.8% C0. This is with another Core2 and laptop-mode is set to use the powersave governor on battery (which is how I tested). When I plug it in, it jumps up to 25%, but I don't really care how active the processor is when it's on battery. Be sure to have cpu-freq-utils installed, as well as loading the right modules (acpi-cpufreq, cpufreq_ondemand, if you plan on using the same governor as ubuntu does), and add `cpufreq` to your DAEMONS array in rc.conf. On my system, with laptop-mode-tools the powertop output is very similar to what Brendan said. Also, the 31k+ wakeups definitely mean there's some issue on your config.

[arch-general] powertop vs archlinux vs ubuntu
hi i've bought a new notebook (hp pavilion dm1-1150sl) and installed archlinux. i have see a strange thing with powertop, i'm running the vanilla arch kernel26, and i have see this behaviour: CnAvg residency P-states (frequencies) C0 (cpu occupata) (31,6%) C00,0ms ( 0,0%) C1 mwait 0,1ms ( 0,7%) C4 mwait 0,0ms (67,8%) Wakeups-from-idle per second : 31483,5 interval: 10,0s --- as you can see, i have a LOT of wakeups per seconds very low c1 states lot of c0 and c4 states, a wattmeter tell me that archlinux consume about 25/26watt Then i have boot a live ubuntu distro and see this: Cnpermanenza mediaP-state (frequenze) C0 (cpu occupata) ( 0,6%) polling 0,0 ms ( 0,0%) C1 mwait 26,7 ms (68,6%) C4 mwait 1,2 ms (30,8%) Wakeup-da-idle al secondo: 281,3intervallo: 15,0s --- as you can see the wakeups are a LOT lower than on arch and we have lot of c1 and c4 state, power consumption is about 20W, the same that i have with win7 (about 18/20w).

However I have all GL applications disabled (I always disable them through xscreensaver-demo), however it doesn't matter. As long as I launch xscreensaver-demo I get FS corruption and system frozen... And if by any reason I get the screen locked (that's the main reason I use xscreensaver) I get the FS corruption and can't do anything... I'm about to get from AUR xautolock, and use xlock with blank screen or matrix, :-) I'll see if can get myself included in the bug report, so I can get updated automatically... Thanks, -- Javier.
