Bug Description

https://errors.ubuntu.com/problem/13c353bac2e4c57f18ad317c692ce4037b230665

Even after clean installation, the system is crashing randomly and logs out, everything not saved is lost. No proprietary drivers, no extensions, nothing installed from outside Ubuntu Store (only Chrome), no applications messing with GNOME or UBUNTU itself.

I thought that the status for the Ubuntu task should remain Confirmed... Only "Fix Committed" after the fix has reached bionic-proposed, which it has not.

Judging by past releases, there should be an upstream version 1.10.1 probably in the near future.

I'm not sure if we need to patch this earlier than that...

@vanvugt Peter, the libinput dev said: "As a general rule, I'm not releasing for every single patchfix, even if it is a crasher on some devices. Canonical should apply the patch for their packages, but the patch will eventually land in 1.10.1 when I get to it." So, yeah, there's that.
