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 : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
