I would love to have :
Option "AreaBottomEdge" "1700"
But that breaks the ClickPad functionality quite a bit.

can you explain what the numbers mean for

Option "SoftButtonAreas" "1950 0 1900 0 0 0 0 0"

i'd like to adapt this to my series 7. it finally has some right click, but the area is tiny. i presume b/c the series 7 and series 9 have differently sized clickpads?

and what is this option?
Option "TapAndDragGesture" "0"

thanks for sharing this gist! this is the best my clickpad has worked with linux!

Hi there!

Super glad that your clickpad is working better now :D I'm finding that it works better in Linux now then it does in Windows!

SoftButtonAreas defines the locations that the right and middle buttons exist on the clickpad.

If you run:
synclient | grep -i edge
The numbers you will care about most are the RightEdge, and BottomEdge. You can use these numbers to figure out about where the right click should start and end. (I usually define it closer to the right side as I end up accidently right clicking a lot otherwise!)

The numbers for SoftButtonAreas go like this:
RightButtonLeft RightButtonRight RightButtonTop RightButtonBottom MiddleButtonLeft MiddleButtonRight MiddleButtonTop MiddleButtonBottom

if you use a value of 0, it generally means "the max value". So in this case, RightButtonRight would be all the way to the right on my clickpad.

If you just want to adjust the location of the right click, then you could adjust the first and third numbers to be some fraction of the edge values from above.

The all 0s for middle button means that it's not defined at all. You are welcome to define those too if you would like middle click to work.

TapAndDragGesture is for using literal finger taps (vs a click) for dragging. I like to disable all of the tap stuff just as a sanity check... though it's not likely needed at all.

You can find tons of information on the configuration options by doing:

man synaptics

Hope this has helped!

thanks lori! definitely helps alot, i'll have to play with it. this is the first bit of code that got my notebook working in linux so i'm much closer to being able to abandon windows entirely now. you should share this around on the ubuntu/mint forums b/c there are a lot of people looking for this.
