By some regression tests it's found this was a direct result of commit f840d7f6870d ("Revert \"pinctrl: intel: Initialize GPIO properly when used through irqchip\"") that was included in stable kernel v4.14.38 commit 94c0308279ec and in Ubuntu generic kernel since 4.15.0-24.26 in bug 1775483. The original upstream bug for that pinctrl fix is at https://bugzilla.redhat.com/show_bug.cgi?id=1543769 for ASUS FX503VD, and it's later found to cause screen backlight failure. Further fixes was landed in later kernel versions, but for 4.15 and older, it didn't seem to justify the necessity of more complex patches into stable kernel, so the pinctrl fix was then reverted instead, and the original touchpad cease to function issue was not actually fixed ever since. [Step to reproduce] 1. Turn on I2C debug messages "i2c-hid.debug=1 dyndbg='file drivers/i2c/* +pt' log_buf_len=32M" 2. Boot into GUI, and start dmesg capturing by `dmesg -w | tee dmesg.$(uname -r)` 3. Move fingers around on the touchpad to generate touch events for 1 minute. [Expected result] Touch events generated all the time throughout the process. [Actual result] Touch event cease to generate after some arbitrary time and there is no way to recover. -- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: gdm 1826 F.... pulseaudio u 3178 F.... pulseaudio DistributionChannelDescriptor: # This is the distribution channel descriptor for the OEM CDs # For more information see http://wiki.ubuntu.com/DistributionChannelDescriptor canonical-oem-somerville-bionic-amd64-20180608-47+bionic-master+X90 DistroRelease: Ubuntu 18.04 InstallationDate: Installed on 2019-12-20 (9 days ago) InstallationMedia: Ubuntu 18.04 "Bionic" - Build amd64 LIVE Binary 20180608-09:38 IwConfig: wlp1s0 no wireless extensions. lo no wireless extensions.
