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. ** This bug is no longer a duplicate of bug 1626935 [yakkety] desktop is black and/or flickering after plugging in a second monitor -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1636486 Title: External screen flickers (esp. in terminals) with xorg modesetting driver on Intel Broadwell To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1636486/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
