Date: Sat, 13 May 2017 10:44:29 +0000 [thread overview]
Message-ID: <bug-195743-2300@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=195743
Bug ID: 195743
Summary: Screen flicker and instability on hdmi monitors with
AMDGPU, EDID problems
Product: Drivers
Version: 2.5
Kernel Version: 4.10.13
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: Video(DRI - non Intel)
Assignee: drivers_video-dri@kernel-bugs.osdl.org
Reporter: keziolio123@gmail.com
Regression: No
Hi, I want to report the bug described in this forum thread:
https://www.phoronix.com/forums/forum/linux-graphics-x-org-drivers/open-source-amd-linux/947352-recent-extremely-annoying-multimonitor-bug-don-t-know-where-to-report
I'll copy the relevant part for convenience:
"basically it acts like monitors are unplugged and plugged back in, and often
the detected EDID is wrong, like dmesg suggests, wrong resolutions are found
and I remain with one monitor right, one in 1024*768 and the other one off, not
even detected.
This happens only with HDMI monitors, the one DVI monitor that I have seems to
always work reliably, and swapping them has no effect, the left one seems to
have always the same problems (wrong resolution).
In the video, the center monitor is DVI, the other two are identical, connected
with hdmi and are affected by the problem.
I'm 100% sure everything was working right until some weeks ago, never had any
issues with xonotic or cheese in years, i've reproduced also with serious sam
fusion beta
GPU is a sapphire RX480"
Here's a youtube video of the problem:

The system now is basically unusable with multiple monitors and 3d apps, with
continuous flicker
