It should be. One way to find out - type:
kernel-config load lv
and see.

Not possible. Don't understand why you want to either.

quite a few are asking for "personalized" freq settings. after a bloody research (that i found the solution from jakiman's sig), i now have the info on how you can set your desired freqs in a certain setting in one command (or simply, make your own setting).

i tried to make it as simple as possible:

-open xterm

-load your desired settings
example:
Code:
/usr/sbin/kernel-config load ideal
after that, your freqs should scale to 500/850mhz

-load your desired max freq
example:
Code:
 /usr/sbin/kernel-config limits - 750
after that, your freqs should scale to 500/750mhz under ideal setting

-load your desire avoid freqs (i dont have any clue for the codes )

-load your desired governors
example you want conservative: (old school style, experts please correct)
Code:
echo conservative > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governors
-review all your settings:
Code:
/usr/sbin/kernel-config show
this will display all settings you loaded, review them carefully before proceeding

-save your setting:
Code:
/usr/sbin/kernel-config save ideal_750
it will be saved at /home/user/.kernel

change ideal_750 to your desired name

-test if your settings work:\
Code:
/usr/sbin/kernel-config load ideal_750

well i think that's it, you can expect posts from experts and i will try my best to correct any errors.

And what about my second problem?
Only people who memorized your earlier message would be able to answer that.

At least you were willing to go to the effort of repeating what the problem is, which he wasn't.

Now I've gone to the trouble of going back and rereading his earlier message. It appears to me that he is saying that with starving and other settings his system becomes unresponsive.

Yes, different settings cause different N900s to react differently. That is why there are different settings. I have found that certain settings make my system unresponsive as well, so I don't use those settings.

yup! that is what i remember that he said.

well starving does not make my device unresponsive, but give it an unexpected reboot every time i activate the setting.

but xlv or ulv does not do any issues,

it went pear-shaped yesterday !
for no apparent reasons the n900 refused to play .avi anymore no boot vid or films , played wmv,mpg ok but no avi. solution after much testing was to remove the scripts and configs from phone , deleted from dbus,.kernel,etc/default,local bin the lot ! had tried increasing voltages but made no difference. once everything was deleted .avi worked instantly !
i have now set up again the scripts but changed to 'conservative' from 'ondemand' and increased voltages much higher (though never reaching overvoltage until 1ghz which i dont use -max 900mhz) and everything working ok .
fingers crossed will continue to work !! . i do like the idea of temperture and batt level cpu control so will post back any more info should it arise

The name 'conservative" misleads some people to think it is in any way safer than ondemand, while it is not.

I suggest not to use conservative governor, unless you actually know the technical difference between conservative and ondemand.
