HowTo: Speed up ubuntu boot process - the way you can feel it.

III. Alter the /etc/inittab file

vi /etc/inittab

then comment out tty4,tty5, and tty6. Just leave tty1, tty2, and tty3. Three vts should be enough for a laptop or desktop user. Save the file.

I'm a bit confused about this part here... Are these the lines that look like:

l0:0:wait:/etc/init.d/rc 0
l1:1:wait:/etc/init.d/rc 1
l2:2:wait:/etc/init.d/rc 2
l3:3:wait:/etc/init.d/rc 3
l4:4:wait:/etc/init.d/rc 4
l5:5:wait:/etc/init.d/rc 5
l6:6:wait:/etc/init.d/rc 6

Or the ones that look like this:

1:2345:respawn:/sbin/getty 38400 tty1
2:23:respawn:/sbin/getty 38400 tty2
3:23:respawn:/sbin/getty 38400 tty3
4:23:respawn:/sbin/getty 38400 tty4
5:23:respawn:/sbin/getty 38400 tty5
6:23:respawn:/sbin/getty 38400 tty6

Thanks for the help--looks like a great guide, and like was said, it's nice to know that there's nothing running you don't need.

you might want to green GDM... i know that some people will go down the list, doing exactly what you did, then reboot to CLI, not knowing what to do...

i3dmaster. Can we list other services that "we" have that "you" may not and get them added to the guide?

ie:855resolu, mdamd-raid (I know related to mdamd), mountvirt, screen-cl and so on.

I dont really know what all of them are but we could get the definitions together for the list.

Yes, definitely. That's something we all should do to get this list useful for more people.

The one with tty1,tty2... at the end. Don't touch the rc ones.

hmm... ok. I can see what you mean on that... I will update the HowTo.

Hi everybody,

In my case turning off Hotplug, sound and correct ATI driver modules are nor loaded. Fujitsu-Siemens Amilo A1630.

It seems readahead is a kind of "preloader". It loads at startup some libs on memory, so that some programs will start faster. But it increases startup time for about 3-4 seconds. So, you can keep it... or not

Another way to load your sound card driver is to add the module to the /etc/modules (the module-init-tool boot up process will load modules in that file) file but you need to know the chip set name of your sound card.

lspci -v

should tell you.
As far as the ATI driver, I am not quite sure why it need hotplug subsystem. Did you compile the driver yourself? If the driver is in the correct place (/lib/modules/$KERNEL-VER/kernel/drivers/video). If you see it, take a look the /etc/modprobe.d/alias file and see if it is added. Also, take a look another thread here talking about how to get ATI driver to work...

Yes, it looks that way. I will try and see if there is any benefits to load it on boot time. Thanks very much and I will update the HowTo on this.
