My system is running Ubuntu 18.04 LTS. I am facing this bug every time I turn on my pc and when my PC wakes up after sleep. Unfortunately, I found no solution when I searched on Launchpad and Bugzilla.
I have also reported this error every time(1000+ times now) I get it, no fixes yet. In spite of the Xwayland crash, I can successfully login via GDM3 and use Gnome desktop without any problem, but I am not able to resume my work when my PC wakes from sleep (this hurts).
Executable path: /usr/bin/Xwayland Package: xwayland 2:1.19.6-1ubuntu4 Problem Type: Crash Title: Xwayland crashed with signal 7 in mieqProcessDeviceEvent() ApportVersion: 2.20.9-0ubuntu72 Architecture: amd64 Machine Type: ASUSTeK COMPUTER INC. GL552JX.
For Bootlog, CurrentDmesg: I will share it when requested via a drive link because it is huge to be posted as text.
Update: The error occurs only when my system is using Intel integrated graphics(Intel Iris Pro 5200). So, temporarily to avoid the error, I have switched to Nvidia Graphics(Nvidia GTX 950M, Driver version: 390.87), no errors since then. But, Dedicated GPU rapidly consumes my laptop battery, I would prefer to use Intel Graphics if the error gets solved.
