Comment 2 for bug 1636486

Hi,

Doesn't looks like a duplicate of bug 1626935 to me!

The flickering in my case happens:
- only when something light happens in somewhere on the external screen (like entering a single character in a terminal window). When nothing happens on screen, or when using graphics-heavier apps (like a web browser), the screen doesn't flicker
- the flickering is not similar to a triple buffering issue neither is related to the nautilus wallpaper -- it looks like a DisplayPort reset (ie, as if you disconnect/reconnect the monitor), with a 2-3s complete blackout of the monitor
- this is specific to the modesetting driver. The xserver-xorg-video-intel driver is fine.
