I had this problem also, and I didn't want to use kde or gnome. So I modified the wmlaptop app to show the power usage of my laptop (also CPU temperature, CPU frequency, cpuload, battery % etc). First I had to modify wmlaptop to use the ondemand cpu governor, and then I copied the relevant powertop source code regarding the power usage into wmlaptop. You can check how wmlaptop looks with my modifications here: While battery is charging the power usage is 'green': http://www.ift.unesp.br/users/crmafra/wmlaptop_ondemand1.png The power usage is written in red when battery is discharging: http://www.ift.unesp.br/users/crmafra/wmlaptop_ondemand2.png You can download this modified wmlaptop (version 1.5) there too. Note that my modified wmlaptop generates a few wakeups, because it polls the cpu frequency and all that. I really would like to know if there is a kernel mechanism which would notify some application whether the cpu frequency changed. I tried to use dnotify to check the scaling_cur_freq file in /sys, but that didn't work (and I think that doesn't make sense :-)) Bye, Carlos _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
