Ubuntu 10.10 Mouse pad hot key settings

Filed under: Uncategorized — admin @ 4:07 pm

This is a quick blog on how to use synclient to configure you Linux laptop mouse pad they way *I* like it.  This was needed for my new netbook.  Its mouse pad was “click pad” mouse pad.  This is a mouse pad that has a one button action under it.  Its an attempt to be more “mac like”, I think.  This is on my HP mini210 net-book (which I really like a lot), and I was lost without a left mouse button.  The default ubuntu 10.10 install that I like to use would have the synaptics mouse pad driver configured in a manner that just killed me to use.  The palm detection is a fail, and the scroll area would get triggered when I least expected it (typically with negative effects on my email or file I’m trying to edit)

First I need to follow :

Specifically I need to add AreaBottomEdge=3900 and JumpyCursorThreshold=200 to synapitcs config.

Basically I need 2 modes of mouse pad behaviour.  1 for web browsing, and one for typing.  After some looking around and experimentation I’ve settled on the following configuration.

  1. work-mode: /usr/bin/synclient TapButton1=0 TapButton2=0 TapButton3=0 RBCornerButton=0 LTCornerButton=2 RTCornerButton=3 VertEdgeScroll=0
  2. browser mode: /usr/bin/synclient TapButton1=0 TapButton2=0 TapButton3=0 RBCornerButton=0 LTCornerButton=2 RTCornerButton=3 VertEdgeScroll=1

There are a LOT of different settings possible with synclient you should explore.  start with running synclient -l to list the current settings.

Next I needed these settings to get applied quickly and easily.  To do this I used the System/Preferences/Keyboard Shortcuts application form the ubuntu menu.  Simply go to the bottom of the list of items and select “Add” to add a Mouse-on short cut that executes #2 listed above, and map it to “windows-key-f6” (on my keyboard this is “Mod4+F6”)  Do it again to make a Mouse-off short cut running #1 above and map it to “windows-key-f7”  or “Mod4+F7”.
