# Can't login through gdm - Loop in login on particular user

I have a local user issue which I don't know how to solve: all users can log without any problem, except one user who is each time kicked back to gdm screen though password authehtication succeeds (no password error message). 'su - {user}' works fine, so not a pwd issue. I tried to remove ~{user}/.ICEauthority and all /tmp files|dirs belonging to this user, but still doesn't work.

I guess there is kind of trivial solution, but can't figure out what it is. :-(

I'm in Fedora 30 under Wayland, more than happy to provide more information if needed.

A bit more details/context:

last shows that indeed the user actually connected on a tty
watch -n 0.1 'who -a' doesn't show the user, even a single time So it seems that login succeeds, a tty is attributed, but it never goes to the who command input source. Could this help? Thanks!


Any idea?
Thanks a lot

Answering to myself, finally succeeded in sorting this out.
Was right, wasn't a system issue but a local one.
In despair, I listed all files/dir in faulty user home which had been modified within a short time range before issue appeared, and finally removed following dirs in ~user/.local/share:

• gnome-shell
• keyrings

Then tried to log with the user, and guess what, worked like a charm! So it was related to one (or all) of these directories. I would suspect .gnome-shell, but no evidence of it.
If now someone wants to try to clarify my answer explaining what may have happened, I would be more than happy and would help the community.
Also I changed the topic to make it more relevant.
Thanks!

• Please, post journal errors/info. At first glance could be a Wayland compatibility issue: did you try to login with X? – mattia.b89 Oct 30 '19 at 11:25
• I can do it. Which extract do you want? What would be hard to understand with Wayland compatibility is that we are 7 users on the computer, and since few days ago all users could log in without any problem; now only one user cannot log in, all others can log in working like a charm. – franquemagnee Oct 30 '19 at 11:29
• you can post full journalctl log – mattia.b89 Oct 30 '19 at 11:31
• full journalctl is 400Mo; is it ok? :-) – franquemagnee Oct 30 '19 at 11:39
• hmm may look like silly question, but how do I attach a file to this question? :"> Should I post entries inline? – franquemagnee Oct 30 '19 at 11:47
