I have same problem with i5-5200U (Lenovo E550). I use the notebook with more monitors (on VGA) and only one (HP Compaq LA2306x) is affected by this bug.
I have this knowledges about that: - it's not connected with display resolution - no syslog/dmesg messages - all power management functions are turned off (monitor and pc) - its quite random, but only same fails causes switching the monitor off...sometimes it only make black horizontal line over the screen for aprox 50ms ... I guess it some glitch on clock signal - there is no problem with VGA cable :-) - DDC/CI is turned off (on monitor) Linux 4.5.0-2-amd64 #1 SMP Debian 4.5.3-2 (2016-05-08) x86_64 GNU/Linux xserver-xorg-video-intel - 2:2.99.917+git20160522-1~bpo8+1 Thank you for fixing it;) cat /var/log/Xorg.0.log [398650.361] X.Org X Server 1.16.4 Release Date: 2014-12-20 [398650.361] X Protocol Version 11, Revision 0 [398650.361] Build Operating System: Linux 3.16.0-4-amd64 x86_64 Debian [398650.361] Current Operating System: Linux cepelka-notebook 4.5.0-2-amd64 #1 SMP Debian 4.5.3-2 (2016-05-08) x86_64 [398650.361] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-4.5.0-2-amd64 root=UUID=ddc15e35-db8c-40c7-95a8-7c6ef8a3033a ro intel_iommu=igfx_off [398650.361] Build Date: 11 February 2015 12:32:02AM [398650.361] xorg-server 2:1.16.4-1 (http://www.debian.org/support) [398650.361] Current version of pixman: 0.33.6 [398650.361] Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.

I've just upgraded to 16.04 "Xenial" and rebooted. Now this external monitor often goes black when I mouse my mouse to the native LVDS screen. I've still not been able to find the exact conditions, but it seems to occur when I don't move the mouse for a long time, then move it to the other screen. The screen goes black and comes back quickly, as if I would have run "xset dpms force off". Also, from time to time, the upper part of my LVDS screen just "scrambles" (you know, like when the old cathodic TVs were trembling...) for a few seconds when I click on some keys on the keyboard (e.g. the CTL-ALT-ARROWS, which are associated to "Desktop"/Tag switching in my AwesomeWM config) For more info: # Executing a few commands found on another page (https://askubuntu.com/questions/28033/how-to-check-the-information-of-current-installed-video-drivers) to provide more info: $ lspci | grep VGA ; lsmod | grep "kms\|drm" ; find /dev -group video ; \ cat /proc/cmdline ; find /etc/modprobe.d/; cat /etc/modprobe.d/*kms* ; \ ls /etc/X11/xorg.conf ; glxinfo | grep -i "vendor\|rendering" ; \ grep LoadModule /var/log/Xorg.0.log 00:02.0 VGA compatible controller: Intel Corporation Broadwell-U Integrated Graphics (rev 09) drm_kms_helper 139264 1 i915 syscopyarea 16384 1 drm_kms_helper sysfillrect 16384 1 drm_kms_helper sysimgblt 16384 1 drm_kms_helper fb_sys_fops 16384 1 drm_kms_helper drm 360448 5 i915,drm_kms_helper /dev/video0 find: ‘/dev/vboxusb’: Permission denied /dev/fb0 /dev/dri/card0 /dev/dri/renderD128 /dev/dri/controlD64 BOOT_IMAGE=/boot/vmlinuz-4.4.0-22-generic.efi.signed root=UUID=a3c0bf21-3b98-45f2-8f95-2abd53cef1e7 ro quiet splash vt.handoff=7 /etc/modprobe.d/ /etc/modprobe.d/blacklist-rare-network.conf /etc/modprobe.d/blacklist-firewire.conf /etc/modprobe.d/mlx4.conf /etc/modprobe.d/fbdev-blacklist.conf /etc/modprobe.d/iwlwifi.conf /etc/modprobe.d/alsa-base.conf /etc/modprobe.d/blacklist-ath_pci.conf /etc/modprobe.d/vmwgfx-fbdev.conf /etc/modprobe.d/intel-microcode-blacklist.conf /etc/modprobe.d/blacklist.conf /etc/modprobe.d/blacklist-framebuffer.conf /etc/modprobe.d/blacklist-oss.conf /etc/modprobe.d/dkms.conf /etc/modprobe.d/blacklist-watchdog.conf /etc/modprobe.d/blacklist-modem.conf /etc/modprobe.d/qemu-system-x86.conf # modprobe information used for DKMS modules # # This is a stub file, should be edited when needed, # used by default by DKMS. /bin/ls: cannot access '/etc/X11/xorg.conf': No such file or directory direct rendering: Yes server glx vendor string: SGI client glx vendor string: Mesa Project and SGI Vendor: Intel Open Source Technology Center (0x8086) OpenGL vendor string: Intel Open Source Technology Center [ 33.140] (II) LoadModule: "glx" [ 34.658] (II) LoadModule: "intel" [ 34.831] (II) LoadModule: "modesetting" [ 34.883] (II) LoadModule: "fbdev" [ 34.916] (II) LoadModule: "vesa" [ 34.989] (II) LoadModule: "fbdevhw" [ 35.092] (II) LoadModule: "dri2" [ 35.092] (II) LoadModule: "present" [ 39.380] (II) LoadModule: "evdev" [ 39.740] (II) LoadModule: "synaptics" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1580219/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
