How can I profile what programs are making use of the HD to load after I type in my login credentials?

It's taking a bit too much time lately.

I never tried it but it seems Bootchart could help you out (it's available in the Software Center).

Bootchart is a tool for performance analysis and visualization of the GNU/Linux boot process. Resource utilization and process information are collected during the boot process and are later rendered in a PNG, SVG or EPS encoded chart.

I'm not sure if it will also profile after login in though.

Bootchart will profile all the way to an idle desktop; it's how the Ubuntu boot time measurements are made. –  RAOF Dec 9 '10 at 5:34

@Oliver Lalonde: He also should install pybootchartgui. Last time I checked, it wasn't installed automatically, but you need it for creating the chart. @RAOF But it will fail if booting is taking too long. In that case you'd adjust the sleep time in the "pre-stop script" section of /etc/init/bootchart.conf –  htorque Dec 9 '10 at 8:14
    
Thanks. I thought it didn't do up to the desktop before, but that's because it seems to have some default stop parameters - running pybootchartgui on it's own made it ignore them. –  Vadi Dec 10 '10 at 17:47
