I followed the wiki how and this thread, so here's exactly what I did:

1. Install kernel-power-settings from the Extra's repository (didn't have extras-testing or extras-devel enabled).
2. Reboot
3. Open x-term
4. Type "sudo gainroot"
5. Type "uname -r"
6. Results showed "2.6.28.10power-omap1", so I guess it installed OK.
7. Entered "/usr/sbin/kernel-load /usr/share/kernel-power-settings/ideal"
8. Opened Conky, and indeed the CPU ran at 850mhz.
9. However, it was a little unstable so I ran "/usr/sbin/kernel-load /usr/share/kernel-power-settings/lv"
10. Opened Conky, now running at 600mhz max.
11. Now I decided to change the limits as I read in this thread, so I entered (again after sudo gainroot) "kernel-config limits 250 850"
12. Got an error: "/bin/sh: kernel-config: not found"

So, what did I do wrong here? I'd like to use the lv settings but with the CPU frequency between 250 and 850mhz. I have no idea what exact version I'm running (V37 as I read here or an older one) because I don't know how to check..

You are not run on latest kernel. "uname -r" should give "2.6.28.10power37".
Try to load latest version and check guidance from
Configuring the kernel settings (of the experimental version from extras-devel) -> mini-tutorial

-normal power . .just for internet (i guess this could be the stock on titan's kernel on my phone at 250 600)
- hight performance . .well to have the phone more responsive in everything (I;m using the titans ideal at 250 950)

let me know what do you think of my configuration

thanks

I think 3 profiles might be enough, but you can add as many as you like.
Voltage setting can be adopted from your present kernel profile, jus edit what frequencies you'll use.

Example:
1) Night profile:
- min: 125MHz, max: 500MHz, avoid: 250MHz
2) Normal day profile:
- min: 500MHz, max: 850MHz (same as Ideal)
3) Max performance profile:
- min 500MHz, max 1100MHz, avoid 950MHz

And reason why to avoid 950MHz

hi, how do you choose what frequency to avoid?
thanks

Hi! I downloaded kernel_power and am using titan's ideal kernel for about 20hours now and works like a charm.. but.. is it supposed to clock down to 250mhz? when I enabled it and checked conky quite often it always clocked down to 500mhz.. but after I received a phonecall (don't konw if that has something to do with this..) it now clocks down to 250mhz in idle..

PS: I'm using the stable version from extras..

This can be done by editing FREQ string in kernel config file.

hi, thanks for your reply.

sorry to be a complete n00b, but whats the command to edit FREQ? after read the link you provided i have no idea what to do.

thanks.

p.s if i use 500mhz - 1000hmz , would you still recommend me to avoid 950mhz? thanks

I think this can work very well.
night profile with the starving configuration right?
normal and max performance with the ideal profile right?

thanks again

Leafpad or some other text editor is OK.
1) Open terminal
2) cd .kernel (I hope you have saved there your own config file. If not do it now. Mini-tutorial)
3) leafpad <your file>
4) remove freqs that you want to avoid from FREQS string
5) sudo gainroot
6) kernel-config load <your file> or kernel-config default <your file>
7) now removed freq are avoided

Here is an example of configuration which use only 125MHz or 500MHz, 250MHz is avoided (not included to FREQS list)

Code:

MINFREQ=125                           <- EDIT THIS
MAXFREQ=500                           <- EDIT THIS
FREQS="0:20,90 125:20,90 500:30,360"  <- EDIT THIS
SMARTREFLEX_VDD1=0
SMARTREFLEX_VDD2=0
GOVERNOR=ondemand
SAMPLING_RATE=150000
IGNORE_NICE_LOAD=0
POWERSAVE_BIAS=0
EARLYSSH=0
FSCK_HOME=0

I strongly recommend everybody to avoid using 950MHz frequency even you have not noticed any problems with phone calls. Other frequencies are not hitting in-band of GSM900.

If Starving configuration is OK (voltage settings), then make couple of copies out of that file and edit MINFREQ, MAXFREQ and FREQS strings in those copy files.

Then just load suitable file when needed

Code:

kernel-config load <your file>

Queen Beacon can be used to change settings from desktop.

I am running from yesterday at 900 Mhz after updating with PR 1.2 and so far so good..nothing strange no reboots no camera app. crashes etc..plus i noticed that now we can use the Screen calibration function too..

The only thing i can`t do is to set the min freq to 125 Mhz..i am editing the pmconfig file with VI and i had tryed with both 125000 and 124999 Hz as minfreq but it always returns me 250Mhz..Any ideas guys!!??
