Step 2 (Optional) Intel® GPU Support

If your system has an Intel® GPU, you can speed up larger Gazebo* simulations by making configuration changes.
  1. Verify that your system has an Intel® GPU.
    sudo lshw -c video |grep driver
    Example output for Intel® Iris® X
    e
    Integrated Graphics:
    configuration: depth=32 *driver=i915* latency=0 mode=1280x1024 visual=truecolor xres=1280 yres=1024
  2. Verify that the drivers are working and enabled:
    sudo apt install mesa-utils glxinfo| grep -i "opengl renderer"
    Examples of output:
    • 10th Generation Intel® Core™ microprocessor:
      OpenGL renderer string: Mesa Intel(R) UHD Graphics 630 (CML GT2)
    • 11th Generation Intel® Core™ microprocessor:
      OpenGL renderer string: Mesa Intel(R) Xe Graphics (TGL GT2)
    • GPU support missing (pure slow software rendering):
      OpenGL renderer string: llvmpipe (LLVM 12.0.0m 256 bits)

GPU Support Missing

Verify that you are in an environment that works.
  1. Check your connection type:
    echo $DISPLAY
  2. If the result is not
    :0
    , switch to an environment that works.
    • Software and hardware environments that work:
      • GNOME* desktop
      • Direct access with a monitor
      • Remote access using KVM over IP
      • Remote access using x11vnc* without any headless configurations
    • Software and hardware environments that do not work:
      • XFCE* desktop
      • Wayland* desktop
      • Headless x11vnc* configurations
      • TigerVNC*
If you are in one of the listed environments that should work but the GPU is still not recognized:
  1. Connect a monitor or other graphical display hardware.
  2. Remove headless configurations:
    sudo rm -rf /etc/X11/xorg.conf sudo rm -rf /usr/share/X11/xorg.conf.d/xorg.conf sudo mv ~/.Xauthority ~/.Xauthority.backup sudo apt install --reinstall xserver-xorg-video-intel sudo apt-get install --reinstall xserver-xorg sudo apt-get install --reinstall x11vnc sudo systemctl enable x11vnc sudo apt install --reinstall gdm3 ubuntu-desktop gnome-shell sudo systemctl reboot
