Comment 12 for bug 1824855

I experience the same problem on my xps9360 (without fingerprint reader) after a clean install of ubuntu 19.10. I never experienced this problem on 18.04 and the earlier ubuntu versions I ran on this laptop. The delay is ~ 15-20 seconds and there are error messages in the Journactl log:

There is also an intersting discussion on the fedora bugtracker about this problem which might be of interest.
