Running in text mode gives strange warnings (and strange behaviour)

[camelator]

one day, I switch to text mode with the following command: sudo systemctl set-default multi-user.target since this day, connecting through ssh give the following message: 'DISPLAY' environment variable not set... skipping surface info and these strange lines in dmesg: [ 42.248674] tegra-xusb 70090000.xusb: WARN: buffer overrun event on endpoint [ 42.255820] tegra-xusb 70090000.xusb: WARN: buffer overrun event on endpoint [ 42.263670] tegra-xusb 70090000.xusb: WARN: buffer overrun event on endpoint

I've tried to fill the DISPLAY environment variable with :0.0 => Same result

I never see this issue with the standard jetson linux version

as I am using a WEBCAM i met strange behaviours sometime with a lot of these strange messages.

Any idea?

I've no idea. The whole Ubuntu 20 on a Jetson Nano came as an experiment. Got a lot of positive reactions, hence the repo on GitHub. Never intended to write a bulletproof OS.

hi, many thanks for your comment, I have positive reactions to that, but my robot a little bit less :) hope someone can help

If you only use Ubuntu 20.04 for the more recent version of Python, consider upgrading only Python on your Jetson Nano.
