[solved] High cpu usage

edit: it was dropbox..

hi, i recently buy a sony vaio e and configure cpufreq, laptop-mode-tools and all other stuff but when i start the pc i get high cpu usage (loadaverage >1 and very loud fan speed, look like running flash ) and little by little it's going down..
today i apreciate that sometime when i'm typing, system not respond and quickly put the letters i wrote.

here some info:

Re: [solved] High cpu usage

It would be more useful for you to open a terminal and type "top" and find out from that what processes are consuming your CPU and RAM - you could take a screenshot and post it here, or take a snapshot with "ps aux" and post that output here so we can help you.

Also, I don't understand why you are having to specify so many modules to be loaded. Do you really need them all?

Re: [solved] High cpu usage

no, i just was testing if some module are causing this, and i use hwdetect and set no autoload module. anyway, i don't understand what they are most...

tomorrow i'll post a screenshot of htop, i had not did it before cos don't reveal any process consuming so
