On this Dell 15-7568, there is a touchpad with the left and right click areas merged into the pad.
Steps to Reproduce
With a clean install of 16.04:
- Place Thumb on left-click area
- Place middle finger on center of pad
- Click with thumb by pressing down
The pointer no longer moves on the screen until:
- Pace thumb on left-click area
- TOUCH (not press) the center of pad
Pointer movement is back to normal.
Has anyone else come across similar issues? I'm trying to track down if this is Dell-specific.
What other useful diagnostic info could I provide?
