so after you uninstall some crap try this:first install rootsh from extras devel.then go to the x terminal and type ."sudo gainroot" and then "apt-get install pymaemo-optify"after that xterminal shows your install cache which is useless and you can erease so type after all "apt-get clean"or when it doesnt work"apt-get remove"try this first and then restart your phone and look with conky what your cpu usage now is
