Touchscreen Sleep - Screen Turns off Backlight Stays on #496

Open johnpernock opened 4 months ago

johnpernock commented 4 months ago

Hi All,

My setup is a Raspi 4B on the 7" Touchscreen. I have it as a display for my homeassistant dashboard on my desk. When it tries to sleep, the screen goes black and the backlight stays on. I have seen code where you can turn it off / on manually but Ive been hitting my head against the wall trying to figure this out automatically.

Has anyone come across this issue and been able to fix it? I just want to be able to have this on my desk but have the screen shut off and wake up when I tap it. Is there a setting or a feature I am missing?

What version of FullPageOS? I did not have this issue when testing a 7'' official display.

is this similar to https://github.com/guysoft/FullPageOS/issues/556 ?

could it be related to special kind of screens?

@Baggerfahrer When I tested the screen here did not go of - could it be some kind of function within the touch screen? If yo use a generic TV screen, does it turn off too?

@guysoft thanks for your reply. i solved (finally :) after roughly 10times of OS reinstalling.... ) my issue by setting the screen blanking off in raspi-config.

No idea why this is necessary, in the former version of FullpageOS with the exact same set-up, this step was not needed.

FullPageOS has no change reguarding that. Its likely a raspberrypi foundation change. You could look at the commit log of rpi-config. It might be a powersace feature. Its worth adding an entry in the wiki.
