Help needed with processor usage 30% (idle )
 

Hello everyone ......

i wonder if someone an help me with this please

i opened conky to find that my processor usage goes

( 26% to 34 % ) and speed ( 250 to 600 ) ....

and the processes are :

hildon-desktop
Xorg
ohmd
conky

and no GPRS or wireless lan connected

i did some searches to find that the processor idle usage ( 2 -3 ) %

so mine looks not normal .....and it is realy killing the battery time]

Can anybody please tell me the reasons ? or where to look ?

thanks

Do you have the flashlight addon app? That one that let you choose between flashlight and camera??
When i had this, there was constat cpu usage for me.

Re: Help needed with processor usage 30% (idle )
 

Do you also have queen beacon widget? The latest one from extras devel eats CPU :p

Re: Help needed with processor usage 30% (idle )
 

if u have flashlight-extra .... delete it
also delete some remains manually . these are the files ."flashlight-extra" from /etc/event.d and /etc/init.d.

this solved my problem

Re: Help needed with processor usage 30% (idle )
 

Thank you all for replying ............ i will try those ........ realy thank you for fast replying

Re: Help needed with processor usage 30% (idle )
 

but don't forget that you will never have 2-3% in conky.
7-10 are normal

Re: Help needed with processor usage 30% (idle )
 

well i found that i do have the flashlight ...and the flash light extra

but when i tried to uninstall them ....... i got ( unable to uninstall ... some application packages are needed by other applications

Re: Help needed with processor usage 30% (idle )
 

did you try on xterm?
dpkg --purge <name of application>

Re: Help needed with processor usage 30% (idle )
 

Thank you all............

it works like a charm.......... now the cpu usage is 5% most of time ....... average from 4 % to 8 % ...........and yes the reason was the flashlight extra and flashlight ...........

forgive me to ask another question...... now the n900 is charging and the cpu frequency is 500 MHz doesnt go less than that .......... is this normal ????

Re: Help needed with processor usage 30% (idle )
 

If you use catorise, install this.

Re: Help needed with processor usage 30% (idle )
 

thank you for replying scyzor ...

yes i use catorize .....but what is that exactly i should install ?

Re: Help needed with processor usage 30% (idle )
 

if you haven't overclocked its normal.nokia has made the cpu to run always at 500mhz while charging

Re: Help needed with processor usage 30% (idle )
 

Thank you atilla ......

i havnt overclocked my cpu....i just got my N900 about 3 weeks ago .....iam loving it ....so iam realy scared to overclock the cpu although i know it would be more kool performance and enjoyment .......

you think it is safe ?

Re: Help needed with processor usage 30% (idle )
 

Install what I linked in the post -> this

Re: Help needed with processor usage 30% (idle )
 

just linking a .deb file from some ip address isn't a very trustworthy source.

Re: Help needed with processor usage 30% (idle )
 

Re: Help needed with processor usage 30% (idle )
 

that's a bit more info, but i still wouldn't install it. the author doesn't even say what the changes were. (apparently it's a build from the latest git repo.)
could be that it needs other components as well.

i guess i'm just too paranoid :)

besides, i use catorise (the only reason he seems to have recompiled hildon-desktop), and i have never encountered such behaviour.

Re: Help needed with processor usage 30% (idle )
 

Catorise is one way to trigger the hildon-desktop bug. This is well attested. Try going in and out of many sub- menus. Chances are the high cpu will come back.
If it does, open a terminal and type "sudo killall hildon-desktop" followed by a return.

Re: Help needed with processor usage 30% (idle )
 

Ooh, thanks. I'd forgotten about the patched hildon-desktop since upgrading to pr1.3.
I used his pr1.2 build for quite a while, and it solved a -major- battery drain problem, so...
Installing that new version now.

Re: Help needed with processor usage 30% (idle )
 

well .... thank you all for replying ........... i will install it .........

Re: Help needed with processor usage 30% (idle )
 

i tried installing .......... i got ( unable to update 'hildon-desktop'.... incompatible application package ) .....

Re: Help needed with processor usage 30% (idle )
 

you need to be root and have downloaded the deb then use the "dpkg -i xxxxx.deb" command to install

Re: Help needed with processor usage 30% (idle )
 

thank you .....it worked .... i installed it using the Xterminal .....is there is a way to know it is installed or working ?

Re: Help needed with processor usage 30% (idle )
 

alright ...HELP again .. processor is usage is up again ........
( 15 - 25 ) % .........
any idaeas ?

Re: Help needed with processor usage 30% (idle )
 

typing "top" in a terminal, what process is shown taking cpu time? If hildon-desktop then it did not install the patched version. If some other prog you installed then uninstall it.

must sleep; good luck

Re: Help needed with processor usage 30% (idle )
 

I dont know if this works for you but VERY strange sometimes when my idle process rises..i install flashlight-extra and then uninstall straight away!! ive done this about 10 times now and works EVERY time and i idle at 0-3%

Re: Help needed with processor usage 30% (idle )
 

handaxe

i thank you very much ........ i tried " top " an watching it for a while ....... but cant figure out wut is taking so much usage ....

Xorg is always the top of them

jimmybonsaville .........
thank you very much ..... it worked .......and yes it is VERY strange solution ........ but after a reboot ...... it comes back high idle again .....

ok guys ........ thank you all for trying to help ....... but i guess iam gonna reflash my device ..... start from zero again and watch what's goin on ........
what is the best way to do that ??? shud i use nokia software updater ?

Re: Help needed with processor usage 30% (idle )
 

Does not matter what route you go. Follow advice on http://wiki.maemo.org/Updating_the_tablet_firmware

Note that you can flash bootloader, kernel, and rootfs only or those AND the eMMc (your photo, music files etc). See page linked above.

Don'r reinstall all your progs and widgets at once as it becomes difficult to spot what may be misbehaving. Do it in batches and test.

Regarding "top", when the prog is running, press the letter "p" to filter the high cpu process to the top of the table.

Re: Help needed with processor usage 30% (idle )
 

thank you handaxe .......

i already reinstalled the firmware using the nokia software updater .....

now the usage of processor is (2%-3%) at idle it (2.4 % most of time )....... i like those numbers....... and using "p" is good thing ........ thanx for that too ....

Re: Help needed with processor usage 30% (idle )
 

BUMP: am running pr 1.3.. do i need catorise to save my battery.. or is the bug solved it pr 1.3?

Re: Help needed with processor usage 30% (idle )
 

You don't need catorise to save your battery. No. I mean. You actually DON'T want catorise because it ruins your battery, unless you download the bugfix stated above. No it wasn't fixed in PR1.3.

Re: Help needed with processor usage 30% (idle )
 

Wrong end of the stick I am afraid :) Catorise is one app that, through no fault of it's own, triggers the hildon-desktop bug and thus negatively affects battery life (great app though IMO). Sadly, although a fix is in the SVN version of hildon-desktop (and this provides the basis for the patched debs), it did not make it into pr1.3 :mad: Poor show by Nokia IMO given the bugs very detrimental effects.

So, install catorise under pr1.3 you should install the patched hildon-desktop deb linked above.

Don't use catorise, you may not see any problem and the fix is not needed.

Re: Help needed with processor usage 30% (idle )
 

Thanks scyzor and handaxe for your quick response.. my i just removed flash light extra and lock daemon.. it brought down my cpu usage to 5 percent.. by battery wouldnt even last for 8 hours earlier.. i hope it does now :) thank you guys :)

Re: Help needed with processor usage 30% (idle )
 

allow me to ask this ..... i know its out of the topic ....... but when i reinstalled software on n900 ..... the programs are not installed anymore ...... but their files are still there ........ is there is anythin to remove them by ? script or something ??

Re: Help needed with processor usage 30% (idle )
 

In terminal as root (or use sudo) "dpkg -P <package name>". This should remove vestiges incl config files. But, as always, your mileage may vary...

Re: Help needed with processor usage 30% (idle )
 

thank you handaxe ....you helped me alot
