Intel Graphics – Fix Screen Tearing with Intel Graphics in Ubuntu 16.04

16.04graphicsintel graphicslubuntutearing

I'm running Lubuntu 16.04 on an old Dell Optiplex 780 with an E7500 and integragrated graphics (GMA 4500). When scrolling and during video playback I get this weird wave form tear in the middle of the screen. I first used the VGA out, then tried the DVI out from a PCI adapter and the issue persists.

Best Answer

Tear-free video

The SNA acceleration method causes tearing for some people. To fix this, enable the "TearFree" option in the driver by adding the following line to your Intel-Xorg configuration file

Option "TearFree" "true"

Try disabling Optimus in the BIOS and use/install the latest nVidia drivers. If those from the repository don't work, download them from nVidia.

Please let me know how it goes; I'm about to purchase a E6520 with dock as well.

Nvidia Screen Tearing in Ubuntu – How to Fix

Create /etc/X11/xorg.conf.d/20-intel.conf containing

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "TearFree"    "true"
EndSection

That should fix everything.

Note: This only works if you're using bumblebee.

Note from comments: Since 10.10 the config file directory is now /usr/share/X11/xorg.conf.d

Starting from Ubuntu 16.04 LTS * you can use the following script to switch between NVIDIA and INTEL's graphics cards and besides it corrects the video/screen tearing on INTELs environment: https://github.com/bauca/graphics-switcher
