The ubuntu dev folk are stupidly in quest of ummm strangestuff
eg The whole wayland debacle. X11 may be old and bloated - fix it - don’t thow away elegant stuff
eg I had auto-login with an app that required /dev/ttyUSBn. They are so clever that the ttyUSB’s have not yet been instantiated at auto-login time.

So solution … maybe try debian, I’m going to.
