We <a\nhref=\"https:\/\/wiki.kubuntu.org\/KubuntuPowerManagement\">started designing<\/a> it right there, and I<br \/>\neven wrote some backend code. Due to a vacation and other obligations, I wasn&#8217;t able to do much work<br \/>\non it last month, but I picked it up again, and it&#8217;s progressing nicely &#8212; to the point where I&#8217;m<br \/>\nstarting to use it myself. Jonathan had done some nice work on it, and I took it over again. Since<br \/>\nthe initial test release, it has seen quite some improvements:<\/p>\n<ul>\n<li>Part of the initial code from Jonathan Riddell<\/li>\n<li>Beautiful icons, thanks to <a href=\"http:\/\/kwwii.blogspot.com\/\">Ken Wimer<\/a><\/li>\n<li>Lots of improvements in the user interface, thanks to <a\nhref=\"http:\/\/www.kdedevelopers.org\/blog\/931\">\\el<\/a><\/li>\n<li>Display of cpu frequency (including multi cpu and cpu hotplugging support)<\/li>\n<li>Largely refactored <a\nhref=\"https:\/\/wiki.kubuntu.org\/KubuntuPowerManagementFeedback\">code<\/a> so it&#8217;s actually fun to work<br \/>\nwith<\/li>\n<li>And of course a bunch of bugfixes<\/li>\n<\/ul>\n<p>\tBesides battery and CPU status reporting, you can configure the power manager to switch to a<br \/>\nlower power state by for example dimming the display a bit, and to perform various actions when the<br \/>\npower cable is plugged, unplugged, when the lid is closed and when the battery is nearly empty. <\/p>\n<p>\tSpecial thanks go out to Jonathan Riddel and Luka Renko for testing it.\n\t<\/p>\n<p>\n\tThere&#8217;s a number of issues with power-manager at the moment, however. First, PyQt (and thus<br \/>\nPyKDE) can not &#8216;listen&#8217; to dbus since the Qt event loop is not yet supported in the python dbus<br \/>\nbindings. We currently work around this by polling every 5 seconds. John &#8220;J5&#8221; Palmieri will be at<br \/>\naKademy, so we might discuss a better solution in Dublin at the end of this month.  <br \/>\n\tSecond, power-manager does not support multiple batteries currently. I cannot work on that part<br \/>\nsince I do not have two batteries I can use in my notebook at the same time. Patches for this are<br \/>\nwelcome, of course. I someone wants to lend me a Thinkpad Ultrabay Slim battery, that&#8217;d also be<br \/>\ngreat (bring one to aKademy, if you&#8217;re there).\n\t<\/p>\n<p>\n\tI&#8217;d like to get more feedback now, please <a\nhref=\"http:\/\/vizzzion.org\/downloads\/kde-guidance_0.6.7svn20060906-0ubuntu1_i386.deb\">download the<br \/>\ntest package<\/a> (packaged for Edgy, it should work well also on Dapper but you might need to force<br \/>\ninstall it) and report back, either <a href=\"mailto:sebas [at] kde [dot] org\"><\/a>email me directly,<br \/>\nor add your feedback to the <a\nhref=\"https:\/\/wiki.kubuntu.org\/KubuntuPowerManagementFeedback\">Wiki<\/a>.
