Subject is all - something eat resources in my Ubuntu.
gnome-system-monitor usually shows me, that for about 400-900mb of memory is used (with only Firefox, Deluge, Deadbeef and usual stuff running) and moreover - both cores of processor is working pretty hard too : ~ 25-60 % for both.
seems strange to me.
tell me please - how can i check what is so hungry in my Ubuntu?
p.s.: got built in video-card and auido card. does it makes sence?
p.p.s.: couple of days ago decided to turn off pulseaudio stuff (got a problem - only one user on one PC could use sound) and changed it to ALSA.
