Hi all,

I've installed Webmin on Lubuntu 17.10 (Ubuntu 16.04.3 LTS), and I'm trying to configure all the processes that are running. Especially the Startup processes, as my machine is fairly old. Lubuntu is helping a lot, but I'd like to disable all non-essential services, etc.

For Windows 7, there's "Black Viper’s Windows 7 Service Pack 1 Service Configurations", and I would like to know if there is a similar guide for Ubuntu derivatives.

(To be specific, I'm looking at the module index from System > Bootup and Shutdown.)

Thanks in advance.

webmin is aimed at servers.
there's no reason it wouldn't work on a normal machine, but i suspect it cannot "reach" your desktop settings.
but lubuntu has its own settings gui, and i recommend you thororughly (the UI is confusing) check that.

for system services, i recommend to read up on systemd, then decide whether you want to maintain it through the terminal (best option) or use some graphical frontend. maybe systemd-manager.

Thank you, but this doesn't tell me what services are essential and what are not. It also doesn't tell me what each service specifically does, but I'll learn about systemd anyway. Thank you.

The kernel is essential, as is the init task (systemd). Everything else is, to varying degrees, optional.
There are, however, deep inter-dependencies. Just try and remove something (anything) and see what else will be deleted as a consequence.

Nobody can tell you what is non-essential for your system. There may be some apparently obvious candidates (glusterfs maybe, postfix ...), but you are the ultimate arbiter.

Good to know. Thank you.
