Public bug reported: This bug is similar to this one: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1683508
I file this as a separate one as suggested by @Kai-Heng Feng. 1.I am currently using Ubuntu 16.04.3, but I reproduced this bug on Linux Mint 18.3 (based on 16.04 as well) and on Ubuntu-Mate 17.10. This is a fresh install, not a dist-upgrade. My laptop is Lenovo Ideapad 320 A6 (very similar laptop configuration to Ideapad 320 ARB).CPU: AMD A6-9220, GPU: RADEON R4 2. Affected Kernel version: 4.13.0-17 Elan Touchpad driver is not working correctly (?) 3. I expected Touchpad to work normally, after installation. 4. Touchpad works for up to 60 seconds and than stops completely. My syslog is spamed with "elan_i2c i2c-ELAN060B:00: invalid report id data (ff)". I can make touchpad stop working in about 10 seconds if I move mouse a lot. In attached syslog, You can see 938 error messages in span of 10 seconds. The more I move/click, the faster it freezes. In this version of kernel xinput is detecting hardware. In earlier versions (kernels 4.4*, 4.10*) there was no touchpad detected. teo@widelec:~$ xinput ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ PixArt USB Optical Mouse id=9 [slave pointer (2)] ⎜ ↳ Elan Touchpad id=12 [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)] ↳ EasyCamera: EasyCamera id=10 [slave keyboard (3)] ↳ Ideapad extra buttons id=11 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)] What I tried: 1.
