Context : I multi-boot different GNU/Linux-based operating systems with a shared
$HOME mount partition. My current list is : Debian, Ubuntu, Solus, Fedora.
Last week, I re-installed both Ubuntu and Fedora to the latest releases. Since then I haven’t been able to login to the wayland sessions on either OSes. Xorg session on ubuntu works but not on Fedora. Both OSes run the latest
GNOME Shell 3.36.1
This affects only my primary user ( the only one that exists and the only one that I use ) on the system. For testing purposes, I created another
test user who is able to login to their wayland session without any issues.
Looking at the
journal, I found this weirdness when I attempted to login with my primary user.

What is that
Unknown option -l that is thrown by
I looked very hard to find any reference to a
-l flag on the internet, but couldn’t find any. Even my Debian buster install (
GNOME Shell 3.30.2 ) doesn’t have it.
Considering that this affects only my existing user and it’s the same error on both OSes, it should be hidden somewhere within my
$HOME directory. I did dig around in
$HOME/.local, but couldn’t find anything consequential. I’ve been scratching my head at this for 2 days now. Can someone please point me in the direction of where to look?
I have a couple of ubuntu-specific ‘
session_migration’ files in
$HOME/.local/share, but that just seem to be a list of migrations that is probably for tracking metadata or something. And it has nothing about any login / GDM-related migrations either.
