Public bug reported: 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 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 - 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. ** Affects: linux (Ubuntu) Importance: Undecided Status: Invalid ** Affects: linux (Ubuntu Vivid) Importance: High Assignee: Timo Aaltonen (tjaalton) Status: In Progress ** Tags: cert-testing-needed ** Also affects: linux (Ubuntu Vivid) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1483320 Title: Migrate Broadwell to use i915_bpo To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1483320/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
