Yes, it is. The following video will show you where the power saving HDMI code is implemented in LynxCI and how to disable it. Why might you want to disable it? Because you are working in LynxCI and displaying it’s output to an external monitor. If the HDMI power savings mode kicks in, the video feed to your HDMI monitor or TV is dropped. This code was originally implemented to lower the power consumption on the Raspberry Pi and to reduce heat generation. Most installations of LynxCI don’t involve the use of a monitor long term, so that explains why this feature was introduced.

As you will see, by deactivating the few lines in the root account crontab, you can prevent the process from executing.
