Fedora 12 Tap-Click Mouse Touchpad

Ever since I installed Fedora 12 on to my laptop, the mouse touchpad has not been behaving as I was used to. I'm used to being able to tap the touch pad, and have it be treated as a click, however this functionality was lacking. I'd just let it slide for a while, as I rarely use the touch pad any ways.

Tonight, however, I was doing some research on other things, and discovered how to enable that, plus several other awesome things.

This is amazingly simple to do. I'm amazed it took me this long to get around to it. To add the tap to click function back to the touch pad, simply go to System -> Preferences -> Mouse from the main menu, or launch it by typing 'gnome-mouse-properties' into the command line.

Then, click on the rightmost tab, Touchpad, and check the box next to 'Enable mouse clicks with touchpad.

While you're there, you might be interested in a couple other features there.

Two-finger Scrolling

I'd never heard of this before. I'm going to say that this is flat out awesome. You know how most touchpads have scrolling built into them: generally on the right hand side there's a column where you can slide your finger to scroll vertically.

I've found that I often hit this accidentally when I'm typing, causing the screen to jump about randomly. Before I heard of Two-finger scrolling, the only option I could envision was disabling it altogether...however, the scrolling is indispensable when you don't have an external mouse plugged in.

If you change the radio button under Touchpad in the Mouse Preferences window to Two-finger scrolling, it changes the functionality to only scroll vertically when you drag two fingers up or down anywhere on the touchpad.

Something Unrelated

What prompted me to go looking this up all began when I wanted to restart the X11 server, and I tried the old key combination of Ctrl+Alt+Backspace and noticed no results. Evidently it was decided to disable this by default to prevent users from mistakenly hitting the combo and losing any unsaved work.

To re-enable it, run gnome-keyboard-properties from the command line, click on Layouts, then the Layout Options button. From this popup, you have access to quite a few different keyboard options. The one of interest here, is titled 'Key sequence to kill the X server'.

Click the arrow to expand the section, and then mark the check box there.

Done.
