How to slow down the mouse's double-click speed in Gnome 2.2
This page explains step-by-step how to adjust the double-click speed of your mouse in Gnome 2.2 for Linux. Many people experience difficulty double-clicking (clicking the mouse button twice in quick succession), because they are unable to do two quick clicks of the mouse button in time. The amount of time you have to complete a double-click can easily be increased to make the mouse more manageable.
Step 1: Open the 'Mouse Preferences' window
Click on 'System' in the menu bar, then 'Preferences' and then 'Mouse', as shown in Fig 1. Alternatively, press Alt + F1 and then use the arrow keys to move to 'System', then 'Preferences', then 'Mouse', and then press Enter.
This will open the 'Mouse Preferences' window shown in Fig 2. The 'General' tab should be selected by default. If it is not, click on the 'General' tab, or press Tab until any of the tabs is highlighted, then press the left or right arrow keys until the 'General' tab is brought to the front.
Step 2: Adjust the double-click speed
Below the 'Double-Click Timeout' header, click on the slider next to 'Timeout', and move it to a setting that allows you a shorter or longer time to complete a double-click. Alternatively, press Alt + T and then use the arrow keys to move the slider.
You can test the speed setting you've chosen by double-clicking on the picture of the light bulb below the slider.
Click 'Close' or press Alt + C to finish and return to the Gnome desktop.
Note: If this does not work it could be because your computer settings cannot be changed due to local IT policies - contact your local IT support for further help.
