Current behavior:

Trying to verify Cypress on WSL2 (Ubuntu 18.04) using VcXsrv times out:

$ npx cypress verify

  ✖  Verifying Cypress can run /home/icorbrey/.cache/Cypress/4.11.0/Cypress
    → Cypress Version: 4.11.0
Cypress verification timed out.

This command failed with the following output:

Fixed by installing xvfb and unsetting DISPLAY, however unsetting the env variable shouldn't be required
