[Kernel-packages] [Bug 1778087] Re: ELAN1200 touchpad jumps around and disconnects

2020-03-27 Thread Gaston Castro
Hi, as an update, on my ASUS-GL503VD the erratic behaviour disappeared
around 5.2.x but still disconnected from time to time. I'm on 5.3.7 now
and disconnecting remains.

I just use: 'modprobe -r i2c_hid' and 'modprobe i2c_hid' to restore it
and keep on going.

Thanks for the effort!

Title:
  ELAN1200 touchpad jumps around and disconnects

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  This is on an ASUS GL503VD laptop and would probably affect other ASUS
  laptops equipped with the ELAN1200 touchpad.

  I am on Kernel 4.17.2 because older kernels did not enable the
  touchpad at all(It was just unrecognized or i2c-hid stopped the
  computer from booting)

  The touchpad works but it has erratic behaviour and disconnects
  randomly. After it disconnects the only way to bring it back is to
  `modprobe -r hid-multitouch && modprobe hid-multitouch`

  Libinput and synaptics can handle the touchpad though I found
  synaptics to be more stable.

  dmesg gets spammed with this whenever I move the touchpad:
  [timestamp] i2c_hid i2c-ELAN1200:00: i2c_hid_get_input: incomplete report 
(16/65535)

  I tried to compile: https://github.com/mishurov/linux_elan1200_touchpad
  Because from what I understand the "jumpy/disconnect" problem is associated 
to the incomplete reports and Mishurov managed to mitigate those. Unfortunately 
some symbols were deprecated in kernel 4.17.2 and it did not compile for my 
system.

  While I can use my touchpad as is right now, and "restart" it with
  modprobe when needed, it would be nice to have it function bug-free.
  (Right after I typed this my touchpad disconnected and I needed to
  modprobe again, I am considering making a cronjob for that)

  Let me know if anything else is needed. Will wait for an apport collection to 
add log files.

2018-06-25 Thread Gaston Castro
I'm on the exact same situation with my ASUS-GL503VD. I have tried with
the xorg synaptics touchpad driver (xserver-xorg-input-synaptics
package) but the erratic behavior remains. Also tried with i8042 and
acpi related kernel commands on the grub config as suggested on external
forums, apparently those kind of commands were successful on other elan
touchpads.

[Kernel-packages] [Bug 1777679] Re: ELAN1200 touchpad not working at all with kernel 4.15+; Recognized as ITE 8910 keyboard

2018-06-23 Thread Gaston Castro
I also have an AsusGL503VD with an ELAN touchpad listed by xinput as:

ELAN1200:00 04F3:3090 Touchpad

I installed the kernel 4.17.2 by .deb packages availables on ppa ubuntu
kernel mainline (kernel.ubuntu.com/~kernel-ppa/mainline/).

The touchpad is detected but cursor freezes and jumps around randomly.
i2c-hid is listed on lsmod and I have tried with the xorg synaptics
touchpad driver (xserver-xorg-input-synaptics package) but the weird
behavior remains. Also tried with i8042 and acpi related kernel commands
on the grub config.

Are you getting completely clean operation? can you provide new
diagnostics files, like your lsmod output?

Title:
  ELAN1200 touchpad not working at all with kernel 4.15+; Recognized as
  ITE 8910 keyboard

Status in linux package in Ubuntu:
  Fix Committed

Bug description:
  Laptop is an Asus-GL503VD

  Touchpad is an ELAN touchpad model 1200.

  This bug is relative to the Asus-GL503VD and any Asus laptop using the
  ELAN1200 touchpad.

  I tried Arch, Debian, Ubuntu 14/16/18, Pop_OS, Sabayon Linux, Fedora.
  Same problem, touchpad is totally unresponsive.

  From what I understand the touchpad is being recognized as a keyboard
  and I cannot get any driver to recognize it: elan-i2c or synaptics.

  The touchpad is also being recognized as a USB device.

  This behaviour was consistent on kernels 4.15.0-22, 4.15.0-23 and 4.17.1.
  Right now trying to make it work on kernel 4.15.0-23 because it seems more 
"main-stream".

  Note: I have a keyboard recognized as AT Translated Set 2 keyboard
  which makes me believe I do not need ITE8910 to be a keyboard.

  Note2: Been researching LKM development. Managed to make a signed 'hello 
world' lkm and make it output in dmesg. Willing to help debug/develop the 
driver for this touchpad.
