Hi, new here, and new to this so excuse my lack if knowledge! I successfully ssh in and followed the commands and the sad face went and touch gui loaded again. I started a print, and all looked good! I went back about an hour later (screen had gone to sleep) bug upon waking it, touch UI has gone and now I have a screen showing a page to download Chrome? Like a windows page would look? Any help gratefully received
On the bright side, you can eat that potato you took the photo with, so you won’t starve today.
(Sorry, not helpful)
Full disclosure I don't run a touch screen and only skimmed the video below.
My post is wild speculation on how the touch screen service works....
Guessing this interface runs in Chrome kiosk mode.
i.e. Kiosk mode is where your browser starts full screen and gives you a kiosk experience.
e.g.
$chromium-browser --noerrdialogs --kiosk https://www.google.com --ingognito
Chrome may have opened a second tab on top of your interface instance.
You could test this by logging into the pi via ssh -> kill chrome - restart in normal mode and check for multiab
See if chrome is running
$ps x | grep chromium
kill via pkill or pid from ps
$pkill chromium
$kill [xxxx]
Set the display to ensure chrome opens on the tft (assuming display 0) and restart chromium
export DISPLAY=:0
chromium
CTRL + C in the terminal will kill chrome
The video shows a couple files which may show you what's going on behind the scenes I'd look here first:
$cat /lib/systemd/system/octoscreen.service
Even if this doesn't run in chrome this filemay start you down the path to find important info.
Hope this helps.
That's great, thanks for your trouble. I'll start here!
