14:15:06 harish: hi, on #fedora-meeting-1 14:15:18 jskarvad, thanks. 14:15:26 harish: np 14:16:41 Next, I pushed pm-utils-1.4.1-8 update that should fix AVCs during F15 suspend/hibernate, bugs #710928, #710890. 14:16:47 It is in update-testing now. 14:17:07 Please give it some positive karma if it works for you. 14:19:01 Next info, jvoscek worked on experimental patch for cronie that should add PM capabilities (e.g. similar thing that windows have for services). 14:20:08 His idea was to add special PM tag (implemented as comment for backward compatibility) that describes the levels of battery on which the script is allowed to run if the machine is running from battery. 14:20:35 If the battery is not enough charged, the task can be postponed several times (described by other meta tag). 14:21:29 He created patch for run-parts to support /etc/cron.* with PM markings in each script header. 14:21:54 He also created patch for cronie to support crontabs with such PM markings. 14:22:14 He evaluates scomes score for 54 cron scripts from F14 and created experimental tags for them. 14:22:27 His patches needs some edits, but I think it is interesting idea. 14:22:35 I will put his results on our wiki soon for discussion. 14:23:24 that was all last-week-news 14:24:19 :) 14:24:50 #topic other 14:25:18 Last time there was an unfinished discussion about one RFE proposed to PM SIG. 14:25:35 It was about creation of experimental alternative configs targeted to aggressive power savings. 14:25:59 I still don't think this idea is a junk. 14:26:42 I did a very quick (5 min) overlook of my fedora configs and I still think there is a room for such experiments. 14:27:10 Some ideas: e.g. increase polling interval for smartd to 60mins or more 14:27:22 increase prelink intervals 14:27:32 increase maxpoll interval for ntpd 14:27:47 shorten queue timeouts for sendmail/postfix 14:28:15 increase number of pre-spowned processes 14:28:25 etc. 14:28:44 Of course not a big win, but at least interesting experiment. 14:28:56 * HanzZ has to read backlog :) 14:29:33 Hanzz: ^^ some practice with wattmeter 14:30:00 you mean to check what the benefit from those changes would be, right? 14:30:41 probably very small, but we could try 14:30:53 Well, I could measure those browsers too :) 14:31:04 that's another part 14:31:10 I count with you ;) 14:31:33 yeah :) but once that meter will be connected and so on :) 14:31:49 we have dedicated machine with wattmeter connected 14:32:07 np at all 14:32:14 :) 14:32:25 looking forwatt to it :) 14:32:27 ;) 14:32:58 about the alternative configs, I wil add this idea to our wiki also (at least) 14:33:09 it is not prio 14:33:14 only idea from some user 14:34:27 defaults should be good enough, and if not it should be fixed (as noted in last meeting) 14:35:19 Anything more to discuss? 14:35:37 I don't think so :) I know what to do :-P 14:35:57 great, thank you for your interests and contribution to PM 14:36:06 np 14:36:32 I will be on vacation next week, so the next meeting is scheduled on 2011-06-22 14:37:02 enjoy :) 14:37:24 HanzZ: thanks 14:38:17 that's all for today, letting approx. 5 minutes for comments 14:40:09 so someone told me to inquire here after the meeting if anyone knows how to adjust the fan speed on an nvidia card if I'm using the nouveau driver. 14:41:14 GlenK: I am not sure if it is supported 14:41:52 jskarvad: well, the nouveau wiki says something like use the usual i2c method. but I have no idea what that means. 14:43:06 GlenK: please move to #fedora-power, I will end the PM meeting now 14:43:21 and I will try to reply to your question there 14:43:50 thanks all 14:43:54 I will end the meeting in 5 14:43:55 4 14:43:56 3 14:43:57 2 14:43:59 1 14:44:02 #endmeeting
