Ubuntu Modify Start Service item

For convenience, a large number of services are started with the http://www.aliyun.com/zixun/aggregation/13835.html ">ubuntu". It's likely to include services you don't want and don't need at all, like you just don't want (like Ntpdate, a service that connects to a time server to set your system time) and you don't need to (for example, HP Print and Scan systems, It is not useful when you do not have a related HP device. Other services are that Ubuntu is forced to operate in order to work better.

Although these services are harmless to the system, their increase increases the startup time of the computer. By deactivating these services, you can make your system faster at startup.

One of the simplest tools for managing startup services is bum-boot-up manager-of course, there are other similar tools for modifying startup services, such as Sysv-rc-conf, a ncurses based tool that can control all the services within the system. Here we will use bum

Install BUM

BUM is a popular software that you can easily install by entering the following instructions

sudo apt install bum

Run BUM

BUM need Superuser privileges to run, we start here

Enter your password when the prompt box appears.

BUM It takes a few minutes to start, please be patient.

Warning: Disabling certain services may prevent your system from starting properly!

With bum you can simply enable or deactivate related services by using the check boxes in front of each service in the hook and choose List.

Working in the first tab of Bum is enough, of course, you can also switch to the ' Services ' tab to see a brief description of the corresponding service to determine which services are not needed for you. If you stop a service that is running, it asks you if you want to confirm that the service is stopped.

Please note that you must clarify the role of this service before you decide to stop a service. For example, when you need to print through cups, stopping the Cupsys service at startup is obviously an unwise choice. Stay away from the check box until you have an explicit effect on any service, unless you find more relevant information.
