Ubuntu – Can “startup applications” be less cumbersome

cpu loadstartup-applications

With this tip I saw there is a total of about 60 applications being launched by startup applications, and at the moment I have to sit back and wait about 45s while the desktop is unresponsive…

How does startup applications work? can I tweak it in some way to make these apps start more gradually, not all together?

I don't want to disable any of them, just stop them all being loaded simultaneously and freezing the desktop

First I saw this tip, but sleep 20;xscreensaver -nosplash seems not to work anymore on Ubuntu 14.04.

So I coded this script execLater.sh and put it at a place in my $PATH, chowned it root:root and mode permissions rwxr-xr-x, and put it on a fully root:root folder structure like /usr/local/bin.

sleep $1;shift;"$@"

So it sleeps before executing the command.

Show all hidden startup applications by following this tip

Now for each startup application.

If there is, for example, this:

xscreensaver -nosplash

change to this below, where "20" is the delay; I used up to "60" knowing I dont care much for some applications; and a minimum of "5" for the ones I care most.

execLater.sh 20 xscreensaver -nosplash

The tricky part

each of these below must have an exclusive delay of "1" because everything else depends on them

/usr/bin/gnome-keyring-daemon --start --components=secrets
/usr/bin/gnome-keyring-daemon --start --components=pkcs11
/usr/bin/gnome-keyring-daemon --start --components=gpg
/usr/bin/gnome-keyring-daemon --start --components=ssh
nautilus -n

My guess is, when all 60 apps startup at same time, these above take longer to complete and so the whole desktop stays unavailable...

If you log when each command was executed, you will understand what applications must have delay of "1", because all others are "actually only executed (?)" or "called?" after these; the above list is not fixed, it is just a tip, just logoff and login (no need to reboot to complete this list) so you can make the tests until you are satisfied with the results - now my desktop is available after only 5 seconds :)
