Running Octodash on a Raspberry Pi Touch Display 2 5inch. (Bullseye)

[cheshirec13]

Here's what needed to do to get Octodass up and running for a Raspberry Pi 4B 4G

Setting up Raspberry Pi Touch Display 2 5”

Utilizing the Octopi v1.0.0 (Bullseye Based)

  ------------------------------------------------------------------------------
  OctoPrint version : 1.11.3
  OctoPi version    : 1.0.0
  ------------------------------------------------------------------------------

In order to get the Touch Display 2 5” (released August 2025) in Bullseye use the following

  sudo apt update
  sudo apt full-upgrade

After the full-upgrade, it still didn’t allow for the Raspberry Pi Touch Display 2 to function making it necessary to run rpi-update and have it recompile the kernel to add the kernel module for the touch display 2

  sudo rpi-update

By default the touchscreen is set of portrait mode ate 720x1280

  nano /boot/config.txt 

add the following

  dtoverlay=vc4-kms-dsi-ili9881-5inch,invx,invy

the invx and invy are needed to rotate the touchscreen (my display is rotated 270 because with the cabling i needed to rotate the screen so that the power and hdmi ports were accessible fro the top).

By default the touchscreen is set of portrait mode at 720x1280, making it necessary to rotate the screen depending on how it sits.

  # Rotate display 270 degrees for landscape mode on Raspberry Pi Touch Display 2 
  lcd_rotate=3

  nano /boot/cmdline.txt
  video=DSI-1:720x1280@60,rotate=270

This gets the screen to rotate into landscape mode, however octodash would still startup in portrait mode which to correct that

  xrandr —orientation right

but to make this a permanent change when octodash loads edit the .xintirc file

  nano .xinitrc 

and add

  xrandr --orientation right 

then save the file and reboot
