Comment 18 for bug 1157678

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

xrandr --output DP1 --auto --primary --output LVDS1 --off

things are fine.

Please see the attachment for an illustration of the issue.
