Hello everybody!
Acer Aspire E1-572 (Elan, Hardware version 3 (Firmware version 0x454f00), driver v. 4.5):
Two fingers scrolling doesn't work, I use Edge Scrolling.
Sometime (not often) something strange happens with touch pad (or a driver):
any touches/movements/swipes stop work, I can see only random press/release events (looks like the right touch pad button is pressed/released).
Sleep/Wake solves this issue (I suppose some initialization is happened after wake) .
It would be nice if keyboard shortcut for enabling touch pad could reinitialize it.
Anyway, thank you for the possibility to use this touch pad!
