Re: [Lubuntu-desktop] lubuntu cpu scaling....
Hi Adam, I've had a stab at putting the frequency scaling information together over at http://forum.phillw.net/viewtopic.php?f=18&t=104 please let myself or Bob know any alterations that need making. For a discussion with someone who has a dual core, Bob can probably help the best as my laptop is the proud owner of a single Intel Celeron M 440. He also has moderator priveleges on the baby forum so any discussions you both have he can put on without needing me ;-) It is his thread :-D Once they're settled and ready I can check with the development team and get them onto the Wiki area. I'm sure you know that getting documentation together does require that we do it, the team is very small. Thanking you in advance for helping lubuntu, Phill. P.S. to everyone, if you have comments to add or if you have any "How To's" please let me know, I'd be really happy to hear from you.

Re: [Lubuntu-desktop] lubuntu cpu scaling....
hi Steve, you can edit here http://pastebin.com/fqZyA04Z or if you have signed up for the C-o-C I will gladly give you mod privaleges on the baby forum. I do recall you saying we need to increase the number of screens for the cube to work? Oh, and I got ragged over doing 'sudo reboot' Linux does not need such things for alterations of the system, Gee, they are strict ;-) Thanks, Phill.

Re: [Lubuntu-desktop] lubuntu cpu scaling....
Hi Bob, I don't have a dual core, can you have a look through the instructions, feel free to post it up as "Dual Core work in progress" on the baby area and leave a note on it to say you're still working on it. As I do not have dual core, I can not give any input at all. I'm sure Adam will be happy to chat with you over it. Cheers, Phill.

Re: [Lubuntu-desktop] lubuntu cpu scaling....
Well, with my old AMD 3800+ X2, I have three steps: 1G, 1.8G and 2G. I got a very similar output to the OP's when I installed cpufreqd: current CPU frequency is 1000 MHz. cpufreq stats: 2.00 GHz:6.49%, 1.80 GHz:0.40%, 1000 MHz:93.11% (394) I tried setting it to "performance" and got the expected 2G all the time. It appears to default to "ondemand" which is, I think, the best default in general. Without cpufreqd installed, everything indicates that I'm running at 1G almost all the time, which is what I would expect. It will only kick in the warp engines when there's a real need to do so. Having said that, I'm not sure I see any problem. It seems to be handling my AMD in just the way I prefer, and allows me to modify it. If there's something specific I should try to help test this, let me know.

Re: [Lubuntu-desktop] lubuntu cpu scaling....
Hi good people, those with such machines, (yeah, Bob, i'm thinking of you) Would you have a 'play' with this and see how you get on. i know it is not lubuntu base system stuff, but the 'advanced' and 'expert' areas are still completely empty. If the team would rather them be on the 'un-official' How-To's over at http://forum.phillw.net/viewforum.php?f=18 I'm more than happy to pop it on there with the usual warning "Not Supported" Whilst I do not want the devs distracted from important things, "children will play" and some of us wish to expand on the base install. I'd also appreciate the solution to http://forum.phillw.net/viewtopic.php?f=18&t=101 which was mentioned on the mailing list, but told that it needs more (That solution was from a dev, so it needs making into what we mere humans would understand). If anyone wants access to any "How To's" over on http://forum.phillw.net/viewforum.php?f=18 that are either in preparation for transfer to the wiki area or should just remain on that area you can contact me. Any person who has signed up for C-o-C on launchpad is automatically given moderator rights on that area so as to able to edit anything, just as we have with the lubuntu wiki pages. I'm sorry I've not been about as much of late, I'm getting the finer points of accessibilty for a site sorted out, expect me to back nagging about ocra and lubuntu :-) Regards, Phill.
