debian+phosh running on PinePhone

[buskmann]

I was trying to change the username, so i logged in via ssh as root, and did:

pkill -9 -u `id -u debian`
usermod -l buskmann debian
usermod -m -d /home/buskmann buskmann

Now the phone wont log in and start phosh.
I assume that some auto login file that has the username "debian" in it or something.
If so, what file should i edit to get my username in there?
And is it maybe possible to use "uid" instead of username?
