I have been using 12.10 for a few days. Just upgraded it from 12.04. My computer, which has a 4GB RAM and 64 bit Intel processor, just goes slow randomly. When I press Ctrl+Alt+F6 and login through a command prompt, I see a number of processes using ps -A.

I get many instances of a process named 'doodle' running. So many that I have to pkill them by hand.

Any idea why this is happening?

Ah. That'll be trying to index your filesystem, which usually slows machines down to a crawl. If you're not using it, remove it :)
