Unable to run on headless server

[xxxfrank]

Hi，i have encounter bugs when i run startx.py on headless server.

(EE) parse_vt_settings: Cannot open /dev/tty0 (No such file or directory)

But i have checked the /dev/tty0, this file exists.

Thanks for your replying

Below is the output when i run this script.

# sudo python3 ./scripts/startx.py 1

Starting X on DISPLAY=:1

@xxxfrank are you running this with docker? Have you tried docker run --privileged? See this.

Looks like you are missing permissions for /dev/tty0.
