Laptop uses only Intel graphics.
Laptop screen is 1366x768. Monitor is 1920x1200.
Moving mouse beyond 1366x768 results in 15 second lag.

The 4.15 misses some i915 firmware files:

$ sudo update-initramfs -k all -u
update-initramfs: Generating /boot/initrd.img-4.15.0-48-generic
W: Possible missing firmware /lib/firmware/i915/kbl_guc_ver9_14.bin for module i915
W: Possible missing firmware /lib/firmware/i915/bxt_guc_ver8_7.bin for module i915
update-initramfs: Generating /boot/initrd.img-4.4.0-138-generic

May them are reason for lockups?
