Check Fix ‘Screen Tearing’ Issue on Linux
Desktop environments are getting better and better at dealing with annoying screen tearing issues. Despite this, users regularly encounter this issue on all popular desktop environments. Since Linux screen tearing issue is still a big problem, today we are going to talk about Linux screen tearing and what to do. On-screen display artifacts are apparent when, for example, noise patterns momentarily show up on the screen when switching from one window center to another.
This can also have the effect when using a video application where parts of the screen appear to be ripped away from the rest of the screen. This happens because the video is not in sync with the screen refresh rate and may be the result of transient problems in the video drivers. This way it should be fixed on the next update or reboot. In this article, we will tell you how to avoid screen tearing on Linux.
Fix ‘screen tearing’ issue on Linux
NVIDIA
You can set the value based on how much RAM you have. 5 to 15 is usually the range you can safely work with. Reboot the computer, and everything should be smoother.
To get started, you will need to enable NVIDIA DRM module settings (modsetting). Start by creating a configuration file in the modprobe directory.
-
- sudo touch /etc/modprobe.d/nvidia-nomodset.conf
Open that file with your favorite text editor and insert the following line:
-
- nvidia-drm options modset=1
Update your kernel’s initramfs to apply your change.
When you’re done, start over. Your computer will work again and everything will be more fluid, but you haven’t done it right yet. Swapping can save you in a pinch, but for something like graphics, it’s pretty awful. The best thing you can do here to increase performance is to reduce your computer’s tendency to use swap space. Start by looking at your current “exchange”.
-
- cat /proc/sys/vm/exchange
That will probably return “60”. That’s the default value, but you can set it much lower. Open “/etc/sysctl.conf” and add the following line to the end of the file:

Intel
Intel graphics on Linux is generally not a big deal. This is probably because integrated graphics tend to be less feature rich and Intel’s driver stack is mostly open source. At Intel, the solution to screen tiering usually comes in the form of some additional configuration. Since Intel uses open source drivers, configuring Xorg will be your most direct route. Create a file at “/etc/X11/xorg.conf.d/20-intel.conf”, then put the following code snippet inside.
- “Device” section
- “Intel Graphics” Identifier
- Controller “intelligence”
- “TearFree” option “true”
- end section
- When you’re done, save and restart.
VSYNC
Vsync is an attempt to synchronize your software’s refresh rate with your monitor’s default hardware refresh rate. In theory, it’s a great idea to make everything as seamless as possible. In reality, sometimes he lives up to his potential, and other times he makes his images a shaky mess. If you are using Vsync and experiencing screen tearing, try disabling it. If you’re not using Vsync, this would be what keeps things online.
KDE
KDE has some fantastic controls, so this can all be done through the KDE Plasma settings. Open the Settings app and find “Hardware” on the page. Under that heading you will find the display settings. Click on them. The main body of the window will be filled with the display settings. The tabs on the side will change. Select “Creator”. Find the “Tear Prevention” option and set it to “Full Screen Repaints.” When you’re done, apply the changes.
Quinn, the KDE composer, is also sometimes part of the problem. Follow your own rules. There is some simple setup you can add to Queen to make it more fluid.
- Create a new file at “/etc/profile.d/kwin.sh”. Open that file and put the following line in it:
- export KWIN_TRIPLE_BUFFER=1
- Please log out of KDE and log back in for the change to take effect.
GNOME
This is a pretty terrible answer, but there isn’t a setting in GNOME directly to manage vsync, but it can still help a lot. If you are running GNOME with Intel or NVIDIA graphics, follow the instructions above. If you’re on AMD, add the following line to your Xorg config.
-
- “TearFree” option “true”
XFCE
The XFCE screen is known for its tiered organization. It has always been a problem and can seriously get in the way. However, there is a fairly simple solution. All you have to do is boot XFCE’s compositor and replace it with a different one, in this case Compton. Open XFCE settings, then look for window manager settings. Click the “Composer” tab and uncheck the “Enable display composition” box. Apply the settings.
Next, install Compton. He is a freelance composer that works great with small desktops. The order here is for Debian-based distributions, but Compton is available on almost all popular distributions.
Go back to XFCE settings. This time click on “Sign in and start”. Add a new app to run at startup. In case you haven’t guessed, that app is Compton. Select the following when prompted. You have several key options to run Compton optimally.
-
- /usr/bin/compton –backend glx –paint overlay –vsync opengl-swc
- Save and exit. You can either log out and back in or run the command to start Compton.
