Ubuntu startup. What can I disable here, and how?

netherfox · 07-04-2012, 09:45 AM

Ubuntu 12.04 LTS, using Unity 2D.

Only have 1GB RAM, so I would like to disable as much of the unnecessary stuff as possible

Hi there,

A lot of the larger apps seem to be desktop related (gnome, unity), which I unfortunately don't use.

The one thing that stands out immediately, though, is apache2, the Apache webserver. Do you need this - are you hosting a website, or doing web development? If not, I'd suggest you disable this.

For info on how to stop services from starting automatically in Ubuntu, try the info in these articles:
* http://askubuntu.com/questions/19320...sable-services
* http://upstart.ubuntu.com/cookbook/#...cally-starting

I hope this helps a little :-)

If you want or need a web server on your workstation, there are other packages that are lighter and smaller than apache. Sadly, I had to stay with apache because the web things I wanted to do required it.

My Linux Mint-12 with Cinnamon workstation has an applet System Menu ==> Preferences ==> Startup Applications where I can turn off desktop things that I don't want running when I login. These are there in addition to the system-level services discussed by cliffordw that start at boot time.

Cheers,

There's a GUI application BUM that lists the daemons rather than every process and allows you to disable them. Unfortunately, it doesn't explain what they do, but at least it narrows the field. That and the start-up programs controller should enable you to cut the junk.
