Hello,
I just installed Ubuntu Desktop OS, but I am a bit confused I am unable to see this option on the raspi-config screen NOT showing the option for the “A12 Shutdown Behavior option”. I made it all the way into the advanced setting options but I only see these as selectable options:
Indeed, Ubuntu does not allow the option to completely cut off power after shutdown through raspi-config. I tried it myself last night, including the EEPROM method, but it still didn’t work.
There are two workarounds:
Write a script that runs before shutdown to manually pull down all GPIO pins — however, this might cause some unexpected errors.
Manually unplug the power cable after shutdown — this is a bit inconvenient.
However, the Pironman5 service automatically shuts down when the system powers off. In most cases, the OLED display and RGB fan will turn off without any extra configuration. So if you don’t make any changes, normal use won’t be affected — only if you have connected other external GPIO devices will you need to be mindful of them staying powered after shutdown.
External GPIO devices, wouldnt include the NVME expansion slots would it?, because right now I had to put the OS on sd card, and im planning to transfer it an nvme im going to install when i assemble the Pironman 5 max.
By “external devices,” we mean devices connected to the 40-pin GPIO header on the Pironman 5 Max.
NVMe drives are powered via PCIe 5V and are not related to the GPIO pins. No additional configuration is needed — you can use them as usual.
