Joe, The issue has returned on my X220 tablet; running 4.13-0.36-generic and the fully updated 17.10 user space.
Every time it happens the laptop display freezes for about 10 or 15 seconds. A concurrent ssh session is unaffected.

Booting the laptop with artful's 4.12 kernel results in a very sluggish system performance (mouse pointer delays) and a high system load. 2. /var/log/kern.log indicates a problem with the display driver (see below) 3. The system works without any issues if the zesty kernel (4.10) is used instead.
