Description Andreas-Johann Ulvestad 2012-12-17 22:27:23 UTC
Description of problem:
I have a Zenbook UX32VD with a pretty well-working touchpad... but there is one issue annoyng the hell out of me and friends with the same laptop: actually using the dedicated clickable buttons is almost impossible under Fedora 18!

The buttons are a part of the touchpad. Under FEdora, they can also be used as a touchpad. Actually hitting a small button, or doing tasks as resizing a window.. or anything else not including pressing a gigantic button is impossible because the mouse cursor shifts a bit when you click the buttons. If you are lucky you are hitting the buttons from directly above, minimizing this, but if you shift your finger a fraction of a millimeter... you miss. Again and again and again.

Version-Release number of selected component (if applicable):

How reproducible:
Every time (ish)

Steps to Reproduce:
1. Hover over something you want to click
2. Try to click it with the buttons (eg right click)
3. If you're not extremely lucky, the cursor will shift slightly, and you miss.

Pop this into /etc/X11/xorg.conf.d/99-synaptics-dontgrab.conf

Section "InputClass"
        Identifier "Don't grab synaptics"
        MatchDriver "synaptics"
        Option "GrabEventDevice" "off"

Then restart the server. Install evemu, and get an evemu-record output for your touchpad when you trigger the bug. Please make that recording as short as possible, i.e. if you don't trigger the bug with a click, cancel and restart evemu-record. More info here: http://people.freedesktop.org/~whot/evemu/

Attach both the device description and the event recording here

Comment 2 Peter Hutterer 2012-12-21 00:12:16 UTC
Actually, not sure we can easily fix this as we don't necessarily know if the button will be pressed in the future. The best option here is to limit the area to outside of those buttons.

xinput list-props "SynPS/2 Synaptics TouchPad"
look for "Synaptics Soft Button Areas", it'll say something like this:

 Synaptics Soft Button Areas (341):	3472, 0, 3900, 0, 0, 0, 0, 0

the third value is the top edge of the button. Then set the dead area to anything below that button.

  xinput set-prop "SynPS/2 Synaptics TouchPad" "Synaptics Area" 0 0 0 3900

Your device may have a different name, use xinput list to find out the name.

to make this configuration permanent, write an xorg.conf.d snippet setting Option AreaBottomEdge with the value you found most convenient.
