[Dell Inspiron 7347] Cannot select multiple file by click and drag with two fingers

[Po-Hsu Lin]

CID: 201406-15234 Dell Inspiron 7347

User cannot do the "click and drag" on the clickpad with more than one finger on 14.04.2 (3.16 kernel)

Steps:
1. Open your home directory.
2. Press the clickpad with one finger, and move the cursor across several files with another finger
3. Put a finger on the clickpad and try to move the cursor across several files after click on the clickpad with another hand.

Expected results:
* You should be able to select multiple files

Actual result:
* Cursor won't move, you can't select multiple files with step 2 or 3, the only way to do this selection is to press the clickpad with one finger and move the cursor with it (or do a double tap and hold)

BTW, I'm not sure if it's a by-design feature.

More debugging information with xev, if you put one finger on the clickpad and press it with another finger, it will return the left click and right click event altogether.

To be more precise, it will turn the ButtonPress (button3, button1) and the ButtonRelease (button3) event right after you press down the clickpad, it won't return the ButtonRelease (button 1) event until you release the button.

@Po-Hsu, can you try the following:

  (1) cat /proc/bus/input/devices to find the sysfs path of the clickpad node.
  (2) ls that node and check the event number of it
  (3) install evtest package and run `evtest /dev/input/eventX` X is the number from (2)

please post the result back here.

There are two events corresponding to these two devices, event5 and event13
For evtest on event5, it can't detect any events that performed on the clickpad, like clicking, scrolling and touching...etc
For evtest on event13 please find the attachment for "click and drag" movement.

[Po-Hsu Lin (cypressyew)]

evtest output for event5

BTW, this issue does not exist with 3.19.0-14 kernel.
