Description of problem: On an Asus S400C laptop, with Fedora 22 beta and Gnome 3.16, trackpad is not functionning properly, and gives an erratic feel, i.e.:
1) right-click is not recognized anymore ans is often assimilated as lef-click left (it seems that in order to have the same usual function as right-click, I have to leave a finger on the trackpad and permor one click with the other;
2) natural scrolling is not working anymore (either in GNOME apps or Firefox)
I've tried to adjust mouse/trackpad settings in GNOME settings panel and to start a session with a fresh user directory (no previous GNOME settings), without success.
Everything was working perfectly well with this laptop under Fedora 21 and previous.
Here are some info on my trackpad:
I: Bus=0011 Vendor=0002 Product=000e Version=0000
N: Name="ETPS/2 Elantech Touchpad"
H: Handlers=mouse0 event4
B: KEY=e420 10000 0 0 0 0
Tested under KDE on Fedora 22 and trackpad was working great.
