All the light bulbs have been changed. A new pool pump is saving me about $80-$90/month. I'd like to do a new fridge but that's not for now. Computers are a big portion of the bill around here and learning how to reduce power is high on my priorities for the next few months. I'm not sure how to handle a multi-use box like this. It's an 8-thread i7 processor. I was wondering about powering off certain core when the machine isn't doing much. Does Intel hardware do that? I need to determine how much power is in the processor, the chipset, memory, the disk drives. The machine is 3-drive RAID1 using data center drives. The WD Green drives just didn't work for RAID. I'm sure 3 drives is adding to my power consumption, but maybe they can be spun down more often. Myth recordings are currently stored on an external USB drive, so that's more power. The problem with this machine is that it's a desktop watching recordings during the day and from 7PM to maybe 3AM it's generally busy recording things. However the TV setup in this house is changing. I'm dropping cable and going with satellite. They provide their own DVR so maybe I'll drop Myth for a while if things work out. That would simplify things, assuming their DVR doesn't consume huge amounts of power. Their DVR supports watching on a Windows PC so I can probably us their app in VMWare which I already use for NetFlix. I appreciate the ideas. I'll likely be asking questions in this area over the next few months. Cheers, Mark
[gentoo-user] Intel High Definition on-board sound controller - optical out working?
I have an optical out on my on-board Intel Hi Def audio controller (also an Intel motherboard) and wanted to route the optical output to my receiver, so I could play internet radio on my home audio system. I got everything plugged in, but the receiver didn't pick up any signal (I made sure all the right settings are selected on the receiver). So my question... Is optical output supported in ALSA and the driver for Intel High Definition audio controller? Do I have to compile with any specific flags to get it working?

Basically the same kind of techniques people having been using on laptops for years to reduce disk activity and power consumption. It's an experiment for a rainy day :) Really great info and ideas Paul. Thanks. I've been playing a lot with power measurements here in my home office. I've got three machines each with their own UPS, two internet connections, 5 monitors, a couple of switches. It all adds up. It's been interesting to look at where the power goes. Keep in mind that my incremental power costs right now are $0.42/KWH. For monthly costs I use 24*365/12 = 730 hours/month. 1) Everything shut off except the power strip plugged into the wall. 5 Watts. Just this power strip plugged into the wall driving 3 UPS's that are turned off costs me $1.53/month. For a power strip? (It has a green and red light!) 2) With all the computers and monitors turned off but the UPS's powered on I used about 25 Watts, so that's about $7.50/month. 3) At idle the laptop uses 75 Watts with no external monitors, 125 Watts with a 23 external monitor. IF I have it on 16 hours/ day that's about 2KWH per day or 61KWH/month for a $25 bill. 4) My new i5-661 desktop driving two external monitors actually uses the same 125 Watts as the laptop so that's another $25/month. 5) My new number cruncher based on the i7-980x with 12GB DRAM, 5 hard drives and two external monitors is about double that at 260 Watts. Simply for power consumption reasons I cannot afford to run it 16 hours per day, and I don't need it that much anyway, so I only turn it on when I have a few days worth of number crunching to do. It's probably costing me $10-$20/month since it's on less than 20% of the time. All in all it turns out I'm spending close to $75/month ($1K/year) just in my office!

Right, without the PPPoE disabled the modem operates in a half-bridged mode (essentially it is a router running dhcp and 1:1 NAT). I would disable NAT, dhcp and PPPoE on the modem so that it is in fully-bridged mode and then see if the problem is resolved. Your symptoms are typical of a half-bridged router and a dynamic IP address from the ISP. Usually, the client on the LAN does not know when the ISP's WAN side IP address has changed and will not pick up the new address until the dhcp lease on the client has expired. To overcome this botched implementation the half-bridged modem has a short lease. This doesn't always work, as I suspect is the case here.

If in X the screen wakes up but there seem to be two images of everything, the second displaced to the right of the original position by a millimetre or so. The problem remains if I exit X and restart it. The only way to fix it is to reboot the machine. This is what the log shows: Starting suspend at Tue Apr 27 23:05:26 BST 2010 hibernate-ram: [01] Executing CheckLastResume ... hibernate-ram: [01] Executing CheckRunlevel ... hibernate-ram: [01] Executing LockFileGet ... hibernate-ram: [01] Executing NewKernelFileCheck ... hibernate-ram: [10] Executing EnsureSysfsPowerStateCapable ... hibernate-ram: [11] Executing XHacksSuspendHook1 ... hibernate-ram: [19] Executing LogoutPidgin ... hibernate-ram: [59] Executing RemountXFSBootRO ... hibernate-ram: [89] Executing SaveKernelModprobe ... hibernate-ram: [91] Executing ModulesUnloadBlacklist ... hibernate-ram: [91] Executing ModulesUnloadBlacklist ... hibernate-ram: [95] Executing XHacksSuspendHook2 ... hibernate-ram: [98] Executing CheckRunlevel ... hibernate-ram: [98] Executing RadeonToolBacklightOff ... hibernate-ram: [99] Executing DoSysfsPowerStateSuspend ... hibernate-ram: Activating sysfs power state mem ... hibernate-ram: [98] Executing RadeonToolBacklightOn ... hibernate-ram: [90] Executing ModulesLoad ... hibernate-ram: [89] Executing RestoreKernelModprobe ... hibernate-ram: [85] Executing XHacksResumeHook2 ... hibernate-ram: [70] Executing ClockRestore ... hibernate-ram: [70] Executing ClockRestore ... hibernate-ram: [59] Executing RemountXFSBootRW ... hibernate-ram: [19] Executing LoginPidgin ... hibernate-ram: [11] Executing XHacksResumeHook1 ... hibernate-ram: [01] Executing NoteLastResume ... hibernate-ram: [01] Executing LockFilePut ...

Re: [gentoo-user] Constraining X display resolutions
On Tue, Apr 27, 2010 at 11:02:53PM +0100, Mick wrote anything else but native resolution makes images and characters blurred. There is one exception to that general rule. If you divide the X and/or Y dimensions by a whole number, the result may be blocky fonts, but at least there is no interpolation. For a 1920x1080 screen, dimensions like 960x1080 960x540 960x360 640x1080 640x540 640x360 480x1080 480x540 480x360 would involve no interpolation. Of the possibilities listed, the only sane ones are 960x1080, 960x540, 640x540, 640x360, and 480x360. If you have a VGA input on the LCD monitor, and if you know the monitor's safe horizontal and vertical frequency ranges, you can go to a site like http://xtiming.sourceforge.net/cgi-bin/xtiming.pl or http://amlc.berlios.de/ and generate custom modelines for the reduced sizes. You may need doublescan for some of the smaller screens. -- Walter Dnes waltd...@waltdnes.org
