I'm facing the bug too on Lubuntu 16.04.1 on a ThinkPad Edge 11 with Kernel 4.4.0-36-generic.
Sorry for the maybe stupid question, but will the fixed kernel version eventually be come via "apt-get update" in the near future or only when 16.04.2 is released? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1553503 Title: multi monitors - black flashes or black screen when the mouse cursor leaves a monitor Status in Linux: Unknown Status in linux package in Ubuntu: Fix Released Status in linux source package in Xenial: Fix Released Bug description: When the mouse cursor leaves one of the screens, there is either : - no problem - the screen becomes black just below the position of the cursor and instantly comes back to normal. - the screen becomes entirely black with some random colored pixels flickering on the far left of the screen. I have to move the cursor to the black screen, otherwise it stays black. It happens on Ubuntu Gnome 16.04 Beta and Ubuntu Mate 16.04 Beta. I have tested with other distributions (Debian Jessie and Fedora) and everything is fine. Hardware : Intel Ironlake (Thinkpad X201) with an external monitor plugged in.
