** Description changed: There are several bugs affecting Broadwell generation graphics in the vivid kernel (3.19), but not found in 4.2rc which i915_bpo module is based on. In order to support our OEM partners (and other BDW users) it would make sense to migrate BDW to use i915_bpo instead. The known (public) bugs this would fix are: - - screen is black after xrandr rotate command + - screen is black after xrandr rotate command https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1446979 - changing the VT causes flicker https://bugs.freedesktop.org/show_bug.cgi?id=85583 - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1472070 + https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1450557 - GPU hangs on resume https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1468232 (and dupes, which I believe there are several of) - and some OEM machines can't always hotplug the HDMI output (no public bug AIUI) the migration should not be too risky, since i915_bpo is already used for Braswell which is same generation as (=based on) BDW.
