Bug ID: 106193
Summary: When positioning a monitor output above or below
initial configuration with xrandr, hard freeze with
graphics artifacts 4.16.2+
Product: DRI
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: major
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org
Reporter: sass.j...@gmail.com
I'm unable to position my monitors outside of an inline configuration. I have 5
monitors, and if I try to position one outside of an inline configuration with
xrandr, it results in a hard lock.
Steps to replicate the process:
$ xrandr --fb 7680x2160
xrandr --screen 0 output shows that the virtual desktop is set to 7680x2160
$ xrandr --output DP-6 --pos 0x1080
At that point, mouse and keyboard become unresponsive. After about 30 seconds,
monitor output shows artifacting. I'll see if I can post an image of what I
see.
It appears this also causes all network activity to stop. The system cannot be
pinged, and SSH server stops functioning. Seems to have the same issues as
https://bugs.freedesktop.org/show_bug.cgi?id=106159 which freezes the system
when connecting or disconnecting a displayport cable.
