I cannot login with GNOME session.
My default Ubuntu is Kubuntu with Plasma, and in the past I have been able to use both Kubuntu and the default GNOME sessions, even with the latest 21.04 release.
I proceeded to update Plasma and that's where things went South. Now I can login to Plasma session, but if I try any of GNOME (X11, Wayland, classic) the session won't start and I will keep seeing the SDDM splash screen.
One thing I can do is open another TTYL, and xstart
a session which does go into Ubuntu GNOME; and that works alright except it is not so cool to have to open that in a ttyl to use GNOME.
I also tried to uninstall and reinstall ubuntu-gnome-desktop
and gnome-shell
, but that didn't solve it.
Thus my questions:
- Why could my GNOME sessions be broken?
- How can I debug or fix them?
Edit: I included the fingerprint-reader
tag, since that's what the answer was about. Although didn't remember about it when posting the question.
