I am experiencing this issue as well on 16.10 on my X1 Carbon 3rd gen (Intel(R) Core(TM) i7-5600U CPU @ 2.60GHz / HD Graphics 5500 (rev 09)). Tried mainline kernels 4.9.9, 4.9.10, and 4.10.0-997-drm-intel-next, and reproduced the issue on all. Also tried pinning libdrm2/linux-firmware/xserver-xorg-* to zesty versions, as well as installing intel-microcode, which made no difference. Xorg is running the modesetting driver.
