Ubuntu 14.04 comes with the overlay scroll bar – which remains auto-hidden and is only shown when you hover your mouse over the edge of the screen. I personally find it difficult most times to use when I need to quickly move up and down an active screen. To disable this feature and restore the normal Windows-like scroll-bar:
Method 1: Using Unity Tweak Tool
– If you do not have the Unity Tweak Tool, then install with following command:
sudo apt-get install unity-tweak-tool
– Launch Unity Tweak Tool > Under System, click on Scrolling > Under Scrollbars, change from overlay to Legacy
Method 2: Via Terminal
– Disable the overlay scroll-bar
gsettings set com.canonical.desktop.interface scrollbar-mode normal
– Enable the overlay scroll-bar
gsettings reset com.canonical.desktop.interface scrollbar-mode
With Overlay enabled
Without overlay enabled
