This HowTo is for those who complaint ubuntu boot-up speed is pretty slow but not willing to install any alternative tools to speed up. The way I use here is not the altimate solution by any means but it does make differences and it does work. Everything done below is by tuning the boot process itself and because everyone’s computer might be different, there is a little risk that something below might break your system. Take your own judgment before you perform a change and always good to do a backup for the /etc dir.
**This HowTo is mainly for laptops and desktops, not for servers.**
Suggestions for this HowTo:
1. I hope you learn something from here but not just a simple copy. So please, **DO NOT** follow exactly what I did and copy to your box. Read the descriptions of services and use your own judgment to determine if you need to keep them on or not. For instance, I turned GDM off on mine to boot to console, but if you do not feel confortable to see console at all, you should keep GDM or KDM on to boot directly to GUI.
2. If you have a question about a boot up service and not really sure what it does, post a question here and see if anybody can help you. Ask before you do if you don’t know. The bottom line to be safe is to leave a service on rather than turn it off if you do not understand.
3. If you see a boot up service that you have but not in here, let us know what it does just like what I did here – give some descriptions and suggestions on whether it should be on or off on a normal laptop or desktop environment.
