Title:
[BDW] VGA output regression on 4.2 (was: Migrate Broadwell to use
i915_bpo)
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Vivid:
Fix Released
Bug description:
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/1450557
- GPU hangs on resume
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1452318
(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.
UPDATE:
Track VGA output regression here, found in 4.2 and fixed upstream by
commit 6fa2d197936ba0b8936e813d0adecefac160062b
