Unity takes ages to start after log in

After I upgraded to 12.04 from 11.10,Unity has started taking too long to start.

Booting from zero to BURG takes about 3 sec,BURG to login screen takes about 5-7sec...n then login screen to unity takes more than 2 min...why so?

I've even tried stuff like disableing networking and stuff...

This sounds like https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/1001138

Try moving aside the file ~/.config/compiz-1/compizconfig/config and then logging in again.

mv ~/.config/compiz-1/compizconfig/config ~/.config/compiz-1/compizconfig/config.backup

If you can login fast now, then you can put back the file and try to just delete these lines as described in the bug comments:

+[gnome_session]
+profile =

Or you can just leave it and use the freshly generated confg.

Try to disable unused applications that start when you boot the system I did it and for me it worked . Disable some startup applications

By default on Ubuntu startup applications are no longer visible, for "security reasons" for new users, those processes that are started at boot time, some may be turned off if you do not need them, speeding up the boot, for make them appear open the terminal and type:

cd / etc / xdg / autostart /

And then:

sudo sed - in-place 's / nodisplay = true / nodisplay = false / g' *. desktop

Then insert our password. Applications now open boot and disable the services that you do not need
