How to fix this?
Here are three fixes you can try out.
Install the Mesa package dependencies
You should first ensure you have all the dependencies installed on your machine to ensure the base graphics drivers for your OS. You can do this by using the following command, provided your distro uses apt-get.
sudo apt-get install -y mesa-utils and libgl1-mesa-glx
Reinstall GPU drivers
Another thing you could do is try and reinstall your GPU drivers. If your Linux distro uses apt-get as the default package manager, you can do this by using the following command.
sudo apt install --reinstall libgl1-mesa-dri

Alternatively, this command can install all required drivers for your distro.
sudo ubuntu-drivers autoinstall
For Nvidia GPUs
Installing the Nvidia docker package can also help fix the issue if you’re using an Nvidia GPU.
sudo apt-get install nvidia-docker
Additionally, sometimes you might have to overwrite the default Nvidia system drivers with the latest one from their website.
