Introduction to two desktop gadgets on Ubuntu

Often use Windows10,sticky notes and wallpaper auto-switching function is very useful. I often use sticky notes to record some information that is saved in real time and is automatically displayed on the desktop when it is started. In fact, there are some similar gadgets on Ubuntu.

1. Variety

Variety can realize the automatic carousel of desktop wallpaper on Ubuntu, change the wallpaper regularly, and some special effects and so on. Official site: http://peterlevi.com/variety/. Install with the following command:

sudo add-apt-repository ppa:peterlevi/ppasudo apt-get updatesudo  Install Variety

2. Sticky Notes indictor

Like sticky notes on windows, Sticky notes indictor on Ubuntu has a very powerful feature. The installation commands are as follows:

sudo add-apt-repository ppa:umang/indicator-stickynotessudo apt-get update  sudoinstall indicator-stickynotes

or download the. Deb directly to install http://ppa.launchpad.net/umang/indicator-stickynotes/ubuntu/pool/main/i/indicator-stickynotes/

In addition, like Youdao dictionary friends can still download the Ubuntu version from the official website to install http://cidian.youdao.com/index-linux.html. In the terminal, switch to the directory where the youdao-dict_1.1.0-0-ubuntu_amd64.deb file is located, and then install it by using the following command.

sudo apt-sudo apt-get dist-sudo dpkg-i youdao-dict_1. 1.0-0-ubuntu_amd64.deb

If an error occurs during installation, try the sudo apt-get-f install as well as sudo apt-get dist-upgrade and sudo apt-get update To update the dependent package.

After installation, a Youdao dictionary can be found in dash, using the same interface and methods as on Windows.

About adding and removing PPA

In Ubuntu, we can install the package by adding a PPA source and then executing sudo apt-get update . The command format is as follows:

sudo add-apt-repository ppa:user/ppa-name

Due to the accumulation of time, we may have added many different PPA sources to the system, and some PPA sources may not be available, causing the sudo apt-get update command to error at execution time. How do I delete an invalid PPA source? The PPA source is usually saved in the /etc/apt/sources.list.d/ directory, and then the source can be deleted by switching to that directory.
