Hi! I've catched a bug in Asus FX553VD laptop.
I am really sorry for sending this message to you, but i can't find
maintainers of this module.
I have ELAN1200 Touchpad, and it's not well managed with hid_multitouch
module.
So, here are the bugs:
- Touchpad freezes randomly, which means it dies.
- When you use two-finger scroll and stop scrolling, module thinks
that you are still in a scrolling mode. Even if you stop scrolling at
all and move your fingers away, and try to point mouse anywhere, it
still thinks that you are in a scrolling mode.
- Five finger tap kills module. We call it "five finger tap freeze".
- journalctl is being spammed with i2c_hid errors (3 times per
second), and it actually influencing on battery life. The message being
spammed is:
i2c_hid i2c-ELAN1200:00: i2c_hid_get_input: incomplete report (16/65535)
Here's link to bugzilla thread
https://bugzilla.redhat.com/show_bug.cgi?id=1543769
Hope you will find out where the bug is.
Sincerely, Vladislav.
