Minimize an application window by single clicking on its icon on system taskbar or dock app launcher is a common used functionality.
This ‘minimize on click’ behavior for Unity’s Left Launcher is not ready in Ubuntu out-of-the-box. So this simple tutorial is going to tell you how to enable this handy feature in Ubuntu 15.10 Wily Werewolf.
1. Install Unity Tweak Tool.
Search for and install unity tweak tool via Ubuntu Software Center:
2. Launch Unity Tweak Tool once installed. Then click the first icon that says ‘Launcher’ to go to its configuration page.
3. Check the box says ‘Minimize single window applications on click’ and done.
The Final release of Ubuntu 15.10 Wily Werewolf will be out in a few days on October 22. Below is how to upgrade your existing Ubuntu 15.04 to Ubuntu 15.10.
1. Backup Data. You should back up your important documents, files, bookmarks, etc.
2. Disable PPAs. Some PPAs may cause the upgrade fail, so do disable all third-party PPAs in Software & Updates -> Other Software tab.
3. Uninstall video driver. If you’ve manually installed proprietary drivers directly from the manufacturer’s website, then before upgrading I recommend you removing these drivers first and reverting to the open-source drivers.
Upgrade Ubuntu Desktop:
1. Open terminal from the Unity Dash, App Launcher, or via Ctrl+Alt+T shortcut key. When it opens, run command to update your system:
sudo apt-get update; sudo apt-get dist-upgrade
2. After that, launch Software Updater via below command:
sudo update-manager -d
Below window should pop-up and prompt that Ubuntu 15.10 is available for upgrade:
Click the Upgrade button and confirm again in next window. Software Updater will fetch and install the files and prompt you to remove unnecessary applications.
Restart your computer once the upgrade process finished.
Upgrade Ubuntu Server:
1. Backup your configuration files if you’re running any services on Ubuntu server.
2. install the update-manager-core via command:
sudo apt-get install update-manager-core
3. Edit the config file via below command to make sure there a line says “Prompt=normal” (without quotes):
sudo nano /etc/update-manager/release-upgrades
After editing, press Ctrl+X -> type y -> finally hit Enter to apply changes.
