Asus touchpad not recognized [SOLVED]

[spaceloop]

Using an Asus F556U laptop, the touchpad is not recognized at all:

Code: Select all

$ xinput list
⎡ Virtual core pointer                            id=2        [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                      id=4        [slave  pointer  (2)]
⎜   ↳  USB OPTICAL MOUSE                              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)]
    ↳ Video Bus                                       id=8        [slave  keyboard (3)]
    ↳ Sleep Button                                    id=9        [slave  keyboard (3)]
    ↳ USB2.0 VGA UVC WebCam                           id=10        [slave  keyboard (3)]
    ↳ Asus WMI hotkeys                                id=11        [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard                    id=12        [slave  keyboard (3)]

Also, this gives me nothing:

Code: Select all

$ cat /proc/bus/input/devices | grep -i pad

Code: Select all

$ uname -a
Linux F556U 4.4.0-2-deepin-amd64 #1 SMP Deepin 4.4.6-4 (2016-07-01) x86_64 GNU/Linux

This is on a Debian derivative (Deepin linux 15.3). I checked the BIOS and the touchpad is enabled there. On windows it works fine, on Ubuntu Gnome which I used before this, it was recognized as a "generic mouse" if I remember correctly which worked okay-ish (multitouch/scrolling not working).

I don't really know what to try now, any help is appreciated!

You forgot to say what touchpad it is!

Maybe you have one of those Elantech "win 10" touchpads that got support in kernel 4.5. You might have kernel errors in the logs then.

I don't really know, how should I find out? I'll take a look in Windows.

Ok, so from system information, I found these relevant values:

Code: Select all

Type Hardware: ASUS Touchpad
PNP-devide-id: HID\FTE1001&COL01\5&1648A21C&0&0000
Driver: c:\windows\system32\drivers\mouhid.sys (10.0.10568.0, 31.50kb (32.256 bytes), 30-10-2015 07:17)

I've found this bugreport of an Asus with similar touchpad driver and problem. Apparently upgrading to kernel 4.6 worked.

https://bugs.launchpad.net/ubuntu/+sour ... ug/1584283

I will try that and report back here.

You would have better luck asking Deepin support channels or forums. It would most likely have different configuration from Debian and I doubt anyone here uses it.

I solved it as follows:

Adding

Code: Select all

deb http://ftp.debian.org/debian jessie-backports main

To /etc/apt/sources
Running

Code: Select all

apt-get install linux-base -t jessie-backports linux-image-4.7.0-0.bpo.1-amd64

[spaceloop]

At least I now have basic pointer functionality, but apparently the kernel recognizes it as a normal mouse and there are no drivers available yet (https://bugzilla.kernel.org/show_bug.cgi?id=120181).

[Head_on_a_Stick]

If you install the kernel metapackage instead then that will be updated and should get the extra functionality eventually

Code: Select all

# apt install linux-image-amd64/jessie-backports
