I have the same issue on Ubuntu 18.04 after upgrading from Xenial last week, but using the Xenial kernel (4.4.0-171-generic). It worked fine before the upgrade. The kernel log shows a kernel oops: a warning followed by a general protection fault, both in the i915 code. Since I'm still on the Xenial kernel it must be the userspace driver update that causes the issue. I've attached the full kernel log.
