Since Maverick Upgrade startup performances are not so good as previous versions. In particular after I log in desktop is really slow to become available to use. From grub to gdm everything is fine and fast as expected. How can I find out which elements slow down desktop loading? I've disabled all useless stuffs to me in Startup Applications, but still I cannot obtain fair performances. Any suggestion?

You can try the alternative (bootchart) I posted here: Intense hard drive access activity immediately after log in

Your trick can be the solution, thanks, I'm investigating. –  skalka Nov 13 '10 at 11:36

BootChart is the definitive tool. Here is a helpful explanation:

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.

Install it (open a terminal):

sudo apt-get install bootchart

Visit the BootChart.org website for documentation and how-to use it. And dont forget to report a bug in case you find one.

I knew about bootchart, but by default it stops monitoring after gdm screen. I'm using htorque's trick to investigate what happens just after I log in. –  skalka Nov 13 '10 at 11:38
    
@skalka: They changed it a few Ubuntu versions ago to keep recording for 45 seconds after GDM by default. So you can still see what happens after you login. Also see this question: superuser.com/questions/32919/… –  Matthew Nov 13 '10 at 16:11

@Matthew: the charts get cropped after compiz, metacity, mutter, kwin, or xfwm4 is loaded (using bootchart's '--crop-after' parameter). –  htorque Nov 13 '10 at 16:43
