@Francis: As far I can tell this is not fixed in 16.04 yet. But you could try the xserver-xorg-video-intel package from the oibaf PPA, which follows the upstream git repo closely (i.e. nightly git snapshots), and should contain the relevant patches/commits.
You probably don't want all the other packages from the PPA, only the xserver-xorg-video-intel package, at least if you don't want to test the other things the PPA aims to provide, and want to keep the packages on your system as close to the official 16.04 versions as possible. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1540953 Title: Xorg crashed when undocking Lenovo T450s from docking station Status in xf86-video-intel: Unknown Status in xserver-xorg-video-intel package in Ubuntu: Triaged Bug description: I have a Lenovo T450s.
