Same problem here. I'm interested if you did a clean install or just upgraded from Karmic? Also are you using any additional applications? This are the applications I use on a daily basis: Firefox, OpenOffice, SMPlayer, Liferea, Skype, Pidgin, Synaptic, Screenlets, Thunderbird, Caffeine, Tomboy, Sunbird.
