Yeah. I wouldn't lock the cpu to 1Ghz permanently as it uses over voltage even with titan's ideal profile or tonism's starving profile. With tonism's starving however, even 950Mhz runs lower than stock Nokia's at 550Mhz. Of course, this may not work stably on many N900's so you have to be lucky.

I am using kernel-config to load the ideal settings from /home/user/.kernel/myconfig which I created with kernel-config load ideal and kernel-config save myconfig. However on subsequent loads with kernel-config load myconfig the voltages are loaded wrong even though they are right in myconfig.

Here is the output from kernel-config show:

active frequencies: 500:38,180 550:30,360 600:33,400 700:38,430 750:45,430 805:45,430 850:48,430 900:48,500 950:54,500 1000:54,500 1100:60,500 1150:72,520

This is in my config:

FREQS="500:30,360 550:33,400 600:38,430 700:45,430 750:45,430 805:48,430 850:48,500 900:54,500 950:54,500 1000:60,500 1100:72,520 1150:72,520"

Any help is appreciated.

Yeah, it's a bug, I posted about it on the "saving battery" thread here - still not sure if it's the frequencies themselves or just the showing of them that are being entered/reported incorrectly. We've got to wait on titan for that, but sadly he hasn't been around the last couple of days.

Yeah, the script is loading the wrong value for 500mhz for some reason. I didn't feel like troubleshooting the script and was hoping someone might have already.

that reminds me of the one locked his device to 850mhz/1000mhz and played OpenArena for 20 mins.

so does this means:

the ARM Cortex-A8 can scale from 600mhz-1000mhz "BUT" it can be destroyed by locking it @550mhz or higher?

I've had a quick look and I can confirm it is a bug only in the show algorithm, so the load is working fine.

It's also very easy to fix; all that's needed is to change line 61 from

Code:
    for f in $allfreq; do
to

Code:
    for f in 0 $allfreq; do
..then all is well

Not sure when it happened but they are UNKNOWN. I've tried almost all unless there is more parameters from XTERM. I'm on HK's PR1.2 supposingly. What i did was:

1. Root or sudo gainroot (same stuff right?)
2. dpkg -l | grep mp-fre
3. ii mp-fremantle-generic-pr 10.2010.12-9 (returned after input)
4. apt-get update (then it ran some updates from the catalogs or whatever)
5. apt-get install --reinstall mp-fremantle-generic-pr (not sure if it's suppose to have quotes on the end like one of the user that had said he had success from post #1500). I tried both with and without then end quotation. The one with out will show me nothing is updated, etc etc. The one with the quotation simply shows a ">" prompt so I have no idea what that means. I switched off the phone and switched it back on and checked settings/about product/ and still has <unknown> and version:<unknown>

Not sure why the heck this is so complicated. Linux is getting really frustrating

I have successfully installed and clocked my device.
But the command: sudo /usr/sbin/kernel-load /usr/share/kernel-power-settings/ideal I get a question about password.

If i gainroot before I run the command, there is no problem.

I would like to use queen beecon widget to change CPUfrequency. I have imported the script to add the widget, but when I click on the widget my N900 hangs and must be rebooted.
I suspect this has to do with the sudo problem ( since sudo gainroot is piped in the queen beecon script)

Any suggestion what to to?

The sudo command is requiring your root password. You need to install rootsh or an ssh-server and setup a root password so you know what it is.

Erm... no.

Sudo actually uses the users password; which by default is not set.

(unless you're running sudo gainroot before running sudo.. then it would want roots password, but that's totally useless as you're already root and no need for sudo at all..)
