I bought a new acer E5-574g-50XN laptop with linpus linux. I removed linpus and installed ubuntu. But the touchpad is not working. I googled tried many things but couldn't fix it.
uname - r gives 4.2.0-23-generic xinput --list shows "SYN1B81:01 06CB:7406 UNKNOWN id=12 [slave pointer (2 )]
i2c-hid i2c-SYN1B81:01 :failed to retrieve report from device.
I also tried settings
synclient TouchpapOff=0 but it automatically gets to
When I blacklisted i2c-hid touchpad stopped working completely.
I am a student and I wanted to learn about linux but I am really frustrated right now. And also when I switch off the laptop and leave it for some time then use it, touchpad works for a little time and then starts lagging heavily. It never stops working but lags so much that it is unusable.
