the purple line
kernel - 3 days old drm-next-4.9-wip
mesa/llvm/libdrm - latest
xorg - 1.18.4 / ~1.19
I have two displays: DVI monitor, always "on" and HDMI (TV) usually "off".
When i turn on HDMI screen:
$xrandr --output DVI-I-1 --primary --mode 1680x1050 --output HDMI-A-0 --mode
1920x1080
On left side TV screen appears purple vertical line.
1) this is 80-90% bug 91041, but amdgpu here and srcreen isn't blurry
$xrandr --output HDMI-A-0 --auto --set audio off
works for me
2) option audio=0 did the job as well
3) Before Xorg/wayland start tty's are clean&black after X/wayland purple line
is visible.
4) problem is probably related to hdmi-audio so i don't even know if it's bug
at all
