How to enable double-click

I can't open folders with double click anymore. Instead I have to right click and press open. How do I reenable it? I'm running Ubuntu 13.04.

Solution 1:

Go to System Settings > Click on Mouse and TouchPad & Check Double Click to low

Solution 2:

Ubuntu 18.04

• Open Settings and click on the left tap Universal Access.

• In the bottom you will find Double-Click delay

Solution 3:

In Ubuntu 17.10 and some other versions, the setting to set the double-click speed doesn't show under the "mouse and touchpad" settings - see here:

However, there is a different solution or workaround:

1. Open the Activities overview and start typing Universal Access.
2. Click on Universal Access to open the panel.
3. Under Pointing & Clicking, adjust the Double-click slider to a value you find comfortable.
