Screen Tearing Test
Why Ask Ubuntu recommends it
Ask Ubuntu users link it as a quick way to confirm whether their Ubuntu desktop actually has screen tearing before or after trying driver and compositor fixes.

What it is
A 1m20s test clip of vertical black and white stripes that moves across the screen. A shift or break in the stripes along a horizontal line means the display is showing screen tearing. The channel owner also links other videos on fixing tearing for Nvidia and Intel graphics.

Below are the steps which worked for me using two screens: Run xrandr to reveal the monitor connection names, resolutions and offsets: Take note of the following two lines which are needed later HDMI-0 connected 1920x1080+0+0 DVI-I-1 connected primary 1920x1080+1920+0 Use the following code as a template to fix screen tearing: Replace the screen names, resolutions and offsets for each screen as per your configuration: nvidia-settings --assign CurrentMetaMode="DVI-I-1: nvidia-auto-select @1920x1080 +1920+0 {ViewPortIn=1920x1080, ViewPortOut=1920x1080+1920+0, ForceFullCompositionPipeline=On}, HDMI-0: nvidia-auto-select @1920x1080 +0+0 {ViewPortIn=1920x1080, ViewPortOut=1920x1080+0+0, ForceFull

Try this [this video] video to see if you still have screen tearing. Try the solution provided here [LINK] . What helped in my specific case was that I switched the driver used for my NVIDIA GP107M when using the "Additional Drivers" application and switched from nvidia-driver-440 to nvidia-driver-435.

I seem to be having problems with screen tearing in Ubuntu 18.04, which got confirmed by running this test: [this video] I searched around in Google for a while, but all I found were recommendations to change the file /etc/modprobe.d/nvidia-drm-nomodeset.conf and add options nvidia-drm modeset=1 But that did nothing. These are the drivers that I am using: [LINK] What could I do to fix this?

I had exactly the same problem and I started testing different things today. In the end, what solved the issue for me (at least on YouTube videos, which is where the error is most noticeable -- for instance here [this video] ) was simply to use compton as whe window compositing engine. Don't mess with the X11 config. If you're using the modesetting drivers, you're good to go. Just disable XFCE's compositor, if it's activated, and on a terminal run: compton --backend=glx If that solves the issue, make compton start at with every XFCE session. I followed the instructions on this page [LINK] , but I didn't use their config file, just the glx backend setting.

This is what I see when I run a screen tearing test video [this video] : [LINK] I am running NVIDIA driver version 460.32.03 and the XPS15 contains the graphics processor GeForce GTX 1650 Ti . I have already tried: Switching the driver from version 460 to 450 Save an X Configuration file with nvidia-settings and add the following params to the Screen Section: Option "metamodes" "nvidia-auto-select +0+0 {ForceFullCompositionPipeline=On}" Info : I can't select FullCompositionPipeline in the nvidia-settings GUI like some solution approaches suggest, because it is not there, even if I select Advanced... see screenshot: [LINK] Any other solutions?

I recently purchased a new Dell XPS15, full options: Intel core i9-10885H, 64GB DDR4, NVIDIA® GeForce® GTX 1650 Ti 4 GB GDDR6 Currently running Ubuntu 20.04.2 LTS (focal). Using the recommended Nvidia-driver-460 (proprietary, tested) driver. I did a kernel upgrade to 5.10.12-051012-generic for Wifi drivers, which didn't work out of the box. This is still not working 100%, and wifi is often gone after coming out of sleep/hibernate (requires a full reboot to work again). I'm not that concerned about this one, since I have a wired connection, but still... Not what you'd expect for a new laptop. My main concern is that the overall performance is just bad. The average boot time is +2 min. On Shut

I know there are many questions regarding this problem, but no solution I have found so far seems to help me with this issue. This is a brand new Dell XPS 9310 with Intel graphics and Ubuntu 20.04. I have screen tearing every now and then. The following solutions did not work: Switching to Wayland. This helped everything look a bit smoother, but after a short while I noticed the screen tearing still occur. Adding various potential contents into /etc/X11/xorg.conf.d/20-intel.conf or to /etc/X11/xorg.conf.d/20-intel-graphics.conf . For example, I tried the solution proposed in [LINK] , the one in [LINK] and some other I have found across the web. Some did not make any difference, some really d
