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).

Error details:

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

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.

  • I am asking this question on StackExchange because I am hoping for an answer due to its large number of users compared to actual bug report sites, For more details please ask it in comments I will share the logs via drive link. – FutureJJ Aug 2 '18 at 10:13
  • I am facing the same problem. It does not happen at every wake, though, only like 30% of the time. – Nicolas Raoul Aug 2 '18 at 10:26
  • What GPU manufacture do you have? – Ilia Rostovtsev Nov 8 '18 at 15:00
  • @IliaRostovtsev It's Intel Iris Pro 5200 + Dedicated Nvidia GTX 950M. This Wayland error appears when I switch to Intel Graphics. I do not get any error while my system is using Nvidia GPU. – FutureJJ Nov 8 '18 at 17:58
  • @FutureJJ ..and you don't use Nvidia proprietary driver, correct? – Ilia Rostovtsev Nov 8 '18 at 21:06

As a root/admin user use vi/vim editor to perform the following changes of the GDM3 custom configuration file






By uncommenting the above line your system will use the Xorg display manager instead of Wayland next time it boots. Just do a reboot and you are done :).

  • Thanks, I'll try and post the results in the comments. – FutureJJ Mar 22 at 7:00
