I am actually considering leaving the HDMI enabled and requiring people to edit the uEnv.txt file to disable it if they actually want to twiddle pins. I can put a check for the HDMI driver being loaded in the LinuxCNC setup script I'm calling at the start of HAL, and prod them to edit uEnv.txt if they try to load a configuration that conflicts. Since there are starting to be hardware options that work with HDMI enabled: https://github.com/modmaker/BeBoPr/wiki/BeBoPr-Bridge ...this seems like it might be a reasonable choice. -- Charles Steinkuehler char...@steinkuehler.net ------------------------------------------------------------------------------ See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.
