I've just installed Ubuntu 16.04 on an Acer Aspire E5-552-T574 and I'm dual booting with Windows 10.
Touchpad works just fine in Windows but in Ubuntu it only works before I log in and for a few seconds after that but then it just stops working. Plugging in a usb mouse works fine though.
xinput gives me the following output for my touchpad:
~$ xinput list ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ Areson USB Device id=11 [slave pointer (2)] ⎜ ↳ Areson USB Device id=12 [slave pointer (2)] ⎜ ↳ SYN1B81:01 06CB:2970 Touchpad id=13 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Power Button id=8 [slave keyboard (3)] ↳ Sleep Button id=9 [slave keyboard (3)] ↳ HD WebCam id=10 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=14 [slave keyboard (3)] ↳ Acer WMI hotkeys id=15 [slave keyboard (3)]
Also here is the relevant touchpad info:
~$ cat /proc/bus/input/devices ... ... I: Bus=0018 Vendor=06cb Product=2970 Version=0100 N: Name="SYN1B81:01 06CB:2970 Touchpad" P: Phys=i2c-SYN1B81:01 S: Sysfs=/devices/platform/AMD0010:00/i2c-6/i2c-SYN1B81:01/0018:06CB:2970.0003/input/input13 U: Uniq= H: Handlers=mouse1 event13 B: PROP=5 B: EV=b B: KEY=6420 10000 0 0 0 0 B: ABS=260800000000003
Some people have been suggesting running the following command:
gconftool-2 --set --type boolean /desktop/gnome/peripherals/touchpad/touchpad_enabled true
also this command:
gconftool -s -t bool /desktop/gnome/peripherals/touchpad/touchpad_enabled true
That didn't seem to work for me. Then I went into the grub and added "i8042.reset" to the line "GRUB_CMDLINE_LINUX_DEFAULT" and then updated the grub:
~$ sudo nano /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="i8042.reset quiet splash" ~$ sudo update-grub
That didn't work so I tried to disable and enable the touchpad:
xinput --disable [id] xinput --enable [id]
Just replaced "[id]" with 13 in my case... but that didn't work either.
I'm not really sure what more I can try, anyone got any suggestions?
EDIT: I can use the touchpad if I change it from Advanced to Basic in the BIOS but that's not much of a solution since scrolling and tapping don't work that way.
