Hello, how to turn off the HDMI, vim and vim2 on UBUNTU.
Nobody know? How Turn off the hdmi?
Wait for psychics who will guess what image you use, with what kernel and other details.
i have a ubuntu mate
I remind myself, anyone :)?
Can you specify more details on
trun off the HDMI?
I do not want to display the image via hdmi at all, I want it to be inactive when the monitor is turned on. I do not want the client to see what is there, because I will produce about 1000 devices and it is important for me.
So you need a headless server, right? You can build the Linux kernel and disable the HDMI feature to achive that. @numbqq will figure out more details or solutions for you.
I need this tutorial for now: P
You can disable the HDMI in DTS, but you need to rebuild the kernel.I will provide a test deb for you latter.
you can write one more description, how to change the (loading KHADAS) logo and block the image display, for example, for 10 or 20 seconds from running
You can try the following command to disable HDMI without modify the kernel.
root@Khadas:~# echo 1 > /sys/class/graphics/fb0/blank

root@Khadas:~# echo 0 > /sys/class/graphics/fb0/blank

You can try to disable HDMI in uboot.
