[SOLVED] LightDM does not enter desktop with a new user

English is not my native language, please excuse typing mistakes and grammar mistakes.

I'm using LightDM and i3wm, and they work well with only one user; when I created a new user and try to use it to login in LightDM, I can't reach my desktop, but the screen turns black when I try to login, and rollbacks to the login page, so I guess I've login successfully. I can still enter desktop through the old user.

Sorry for pasting long logs, but I can't determine which of them is useful.

Re: [SOLVED] LightDM does not enter desktop with a new user

I created a new user

How exactly?

Assuming the new username is (still) "test":

grep test /etc/passwd
stat ~test
id test

Re: [SOLVED] LightDM does not enter desktop with a new user

Solved: I used a long user name(8 characters). But why there is such a limit?

There is no such limit.

But when I deleted that user and created another one with a shorter name, this problem disappears.

Re: [SOLVED] LightDM does not enter desktop with a new user

The limit is 32 characters: `man useradd`.

Re: [SOLVED] LightDM does not enter desktop with a new user

By the way, the user name caused this issue is virginia. Does this name be used anywhere? I did not find it in /etc/passwd

Re: [SOLVED] LightDM does not enter desktop with a new user

I'm pretty sure the way the original user was created is the cause here, but it's not a length limit.

Edit: the 8-glyph username would be "virginia" and aside "lightdm" it's the longest name in the log and you cannot create 33-char users itfp.
There must have been another issue.

Re: [SOLVED] LightDM does not enter desktop with a new user

I'm pretty sure the way the original user was created is the cause here, but it's not a length limit.

The way I create it is

useradd virginia
passwd

And after a failed login attempt, I created /home/virginia and called `usermod -d /home/virginia virginia`.

Edit: After several experiment, it seems that to create a user with no home directory is the cause of this issue; even if you create one and reset it using `usemod -d`, this issue still appears.

Re: [SOLVED] LightDM does not enter desktop with a new user

And what ownership/permissions did /home/virginia have? (Because the $HOME access is typical for failed logins since many session processes desperately want to write there)

Oh, I created it using root...

Thanks!
