In a perfect world we'd get to the roots of every problem, but in reality we don't have the time to keep debugging issues that seem to be gone. Especially in areas where we've done a lot of fixing upstream. > Also, we need to > identify which patch fixed the issue so that it can be back-ported. Both 4.5 > and 4.6 kernels have this problem. If the v4.6-rc kernels still have the issue, but drm-intel-nightly works, it should be a pretty straightforward reverse bisect to find the commit that fixed the bug. If you provide that, it may be possible to do the backport. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1554613 Title: screen flickering on XPS13 9350 Status in Linux: Fix Released Status in linux package in Ubuntu: Triaged Bug description: see LP: #1552304 does not affect 4.4.0-8 affects 4.4.0-9 to 4.4.0-16 ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: linux-image-generic 4.4.0.11.12 ProcVersionSignature: Ubuntu 4.4.0-8.23-generic 4.4.2 Uname: Linux 4.4.0-8-generic x86_64 ApportVersion: 2.20-0ubuntu3 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: tbonfort 1498 F.... pulseaudio CurrentDesktop: KDE Date: Tue Mar 8 09:57:12 2016 HibernationDevice: RESUME=UUID=3248e0d7-0dac-4ccc-8982-b5ac5ce6ed5e InstallationDate: Installed on 2016-01-07 (61 days ago) InstallationMedia: Ubuntu 15.10 "Wily Werewolf" - Release amd64 (20151021) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 0c45:670c Microdia Bus 001 Device 002: ID 0a5c:6412 Broadcom Corp.
