Ubuntu10.04 the boot time is only 25-30 seconds after the new installation, but after a period of time, the boot start time is increased to around 1 m20s. after the desktop wallpaper appeared, the loading speed of the Panel was very slow, so I thought of optimizing the startup project.

Method 1: Start the application using the built-in system

Choose system> preferences> Start application,

One is that the system can be stopped by default but it is not frequently used. The options include remote desktop, visual assistance, Bluetooth manager, personal folder sharing, hardware update, power management, and print queue. ubuntu one, evolution reminder, logon sound reminder, disk report

The other is that after the software is installed, the program is automatically added to the startup application. For example, you can delete pandatv and conky by yourself.

Method 2: Use boot-up Manager (recommended)

The following is short for the boot-up Manager (bum ).

Bum introduction:

In the release of the Debian series, the system reads/etc/init at startup. d. If you want to make these scripts not work, you need to change the script permission. However, this is complicated. To make it easy for you to mess up your computer, bum uses the GUI to configure the startup script of your system.

Bum installation:

Sudo apt-Get install bum

Bum usage:

Find bootup-manager in system> Application

Wait for the first time, and wait for the software to generate the disk cache.

Select "advance", three tabs will appear: Summary, service, startup and shutdown script

On the summary tab, configure the startup items of the system.

Udevmonitor system device-keep, NVIDIA-kernel graphics kernel-keep module, Plymouth uth boot animation-keep, network-
Manager Network Manager-keep, ACPI-support power supply and hotkey management-keep, pulseaudio sound management-keep, kernleloops do not understand

What is the function of "keep", "preload", "pre-load", "keep", "acpid", "Power Management", "apache2", "off", "ATD scheduled task", and "bootlog "?
Log-Close, cron scheduled task-open, cups printer-Close, MySQL database-Close, openvpn-Close, ssh-Close, tor Relay Service-off
Close, winbind-close ........

If the program installed in the system is different from the software, the content on the summary tab will also be different and should be adjusted according to personal circumstances.

Appendix: How to view system boot time

Open the Software Center, search for bootchart, and install the two searched software.

After the startupThe/var/log/bootchart folder contains a PNG image.
Tgz file, which can be executed
The tgz file in the/var/log/bootchar/folder of pybootchartgui is enabled. The PNG diagram records some column actions started by the system.

Bootchart is started by default. If you do not like it, you can delete it.

Sudo apt-Get autoremvoe bootchart pybootchartgui-Purge
