Top does not show anything unusual. The user's home directory is not
encrypted. I have disabled Akonadi and Nepomuk. What else should I
check?
Try:
$ ps aux | awk '$11!~/\[*\]/ {print $6/1024" Mb --> "$11,$12,$13,$14}' |
sort -g
(all one line of course)
or
$ ps ax -o rss,cmd --sort rss

For virtual memory:
$ sudo apt-get install memstat
$ memstat
And if you'd like to see the virtual memory assigned to the memory hog
shown in ps, just get the pid first & then run memstat. Example:
$ ps x | grep desktop
$ 2259? Sl 0:05 /usr/bin/plasma-desktop
$ memstat -p 2259

$ info /usr/share/doc/memstat/memstat-tutorial.txt.gz
You can also use vmstat for virtual memory:
http://manpages.ubuntu.com/manpages/precise/man8/vmstat.8.html
And a nice write up on how to use it:
