Hi DomieMic65,

what is your goal?

HDMI can be switched off with:
Code: Select all
/opt/vc/bin/tvservice -o

and on:
Code: Select all
/opt/vc/bin/tvservice -p


The local browser can be switched off on the settings page.

Thank you very much Frank
Just thought that as long as I do not use HDMI it will be better to turn it off!

I gave the order and rebooted but the HDMI is still shown as an option as sound output!
Is this OK?

Hi DomieMic65,

The commands i gave you are not persistent and are for video output.

Depending on the kernel version the HDMI and analog audio outputs can be disabled by adding
Code: Select all
dtparam=audio=off

to your /boot/config.txt

Oh I see...
I use the default kernel!
Should I add it at the end of the .txt ?
Should I put # at the start?

Thank you again!!!!!
