Hi,
I have a similar issue, without the suspend/resume cycle on gen4.
For me it is sufficient to attach an external screen with display port and
xrandr --output DP1 --auto --primary --output LVDS1 --off
This is 100% reproducible.
curiously enough if I do
xrandr --output DP1 --primary --auto --output LVDS1 --auto --right-of DP1
and then
things are fine.
Please see the attachment for an illustration of the issue.
