How do I enable low graphics mode (llvmpipe rendering) in Unity?

Solution 1:

There is an environment variable you can set, UNITY_LOW_GFX_MODE

Running

UNITY_LOW_GFX_MODE=1 unity 

should replace your existing session with the "low graphics mode" desktop.

If for some reason you want to make it permanent

• For your user:

  Add the line

    export UNITY_LOW_GFX_MODE=1
  

  to the file ~/.xprofile (create one, if it doesn't exist).

• Or globally:

  Create a file /etc/X11/Xsession.d/99force-llvm and add above line (requires root permissions, see this answer about how to create a file as root).

  You can set this globally in one step by running the following line inside a terminal:

    echo "export UNITY_LOW_GFX_MODE=1" | sudo tee /etc/X11/Xsession.d/99force-llvm
