I just in installed Ubuntu 22.04 and planning to use the board as photo frame on cron job (script) during certain hours of the day.
This is how I did on my raspberry pi(, that fried recently after about 7 years of service)!
However, I can not turn off display.
Commands I used on RPI do not work. Tried all kinds of various methods to turn off display
- xset
- vcgencmd
- xscreensaver
- tvservice
- All of the above as my <username> as well as "sudo"
All of them either don't do anything or blanks the screen but does not turn it off.
For some of the above commands it complains regarding
- VCHI initialization failed
I tried various things including sudo as well as adding my username to the video group, etc.
Nothing works.
Any help is greatly appreciated before I decide to return the board.
Thank you.
