Bug ID: 116431
Summary: Screen Flickering On Intel
Product: Drivers
Version: 2.5
Kernel Version: 4.5.0
Hardware: Intel
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - Intel)
Assignee: intel-gfx-bugs at lists.freedesktop.org
Reporter: carlo.abelli at gmail.com
CC: intel-gfx-bugs at lists.freedesktop.org
Regression: No
I have a Dell XPS 13 running Arch Linux. Updating to kernel version 4.5.0 has
caused screen flickering (quick black flashes that come in bursts). Downgrading
to 4.4.5 does fix this flickering. Not sure exactly what the issue is but it
persists whether the xf86-video-intel driver is installed or not.
dmesg reports the following error when running kernel 4.5.0 but not 4.4.5:
[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO
underrun
Perhaps this is related. Here the thread on Arch Linux forums:
