This short guide will teach you how to disable the screensaver, or "screen sleep", that occurs after a few minutes of inactivity when using the TouchUI plugin. This will ensure that your OctoPrint touchscreen is always showing relevant information without needing to tap the screen.
Posted in these interests:
Make sure your TouchUI bootloader is up to date by connecting to your Raspberry Pi:
ssh pi@octopi
Then, run the following commands:
cd ~/TouchUI-autostart/
git pull
sudo service touchui restart
If you made changes to your TouchUI files previously before and receive a pull error, run the following:
git reset --hard
Edit the TouchUI default file using the Nano editor:
sudo nano /etc/default/touchui
Change DISABLE_SCREENSAVER=false to DISABLE_SCREENSAVER=true. Then, press CTRL-X to exit and then Y to save.
Finally, restart the TouchUI service:
sudo service touchui restart
You're all done! NO MORE SLEEP... PRINT THINGS FOREVER.
