Using Fedora 31, pam_u2f and a Yubikey5 works well after:
authselect select sssd with-mkhomedir with-pam-u2f with-sudo without-
pamu2fcfg –u[username] > ~/.config/Yubico/u2f_keys
However, from the console (without GDM, multi-user.target for example)
it does not work: Linux will ask for my password where the yubikey
should be sufficient.
Any ideas what could be wrong?
I have chrony running and pointing to my ISP's time server, not the Fedora
pool, so it's always the same NTP server.
This box is up 24/7, and I just rebooted it. And I get this, after a reboot:
Nov 23 08:53:10 shorty chronyd: System clock TAI offset set to 37 seconds
Nov 23 08:53:10 shorty chronyd: System clock wrong by -5.652285 seconds, adjustment started
Nov 23 08:53:10 shorty chronyd: System clock was stepped by -5.652285 seconds
This was a reboot, and not a shutdown.
I believe that something should be saving the system time to the hardware
clock, so after a reboot things are more or less where they are, and this
looks like is not happening. I should not have chrony adjust time by that
much after a reboot. Anyone know where to investigate this further?
I upgraded 29-> 30. Now I can't even get to the boot screen. I've made
a live usb stick, but the stick only wants to install a completely new
system. Is there any way to use the stick to troubleshoot the existing
If I had to guess the upgrade screwed up the the UEFI boot. I can boot
to bios, but not to the boot loader.
Radiotray on my machine running Fedora 31 does not output any sound.
However, everything regarding sound on my computer works fine (e.g.,
YouTube, VLC, etc.)
Thanks in advance,

My installation has a default of English (UK) but occasionally I use Japanese so I installed Japanese language support.
When using the Japanese IME one of the keyboard shortcuts is Alt+`. However, when I use this it brings up an
application switch screen.
I looked through the Settings -> Devices -> Keyboard Shortcuts but there is nothing defined for Alt+`. I also noticed
that "Switch Application" is set to Super+Tab (which works) but Alt+Tab does the same thing even though this is not
So my question is, how can I disable these unwanted keyboard shortcuts?
How to configure 24 hour time, instead of AM/PM, in Thunderbird 62.2.0
Presently I have created /usr/bin/thunderbird24h:
and rebooted but the AM/PM time is still being used. Have I nissed
something or has something changed since Fedora-20?
My .bash_profile looks like this:
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
# User specific environment and startup programs
# the end.
But I want the KSysGuard to be launched only when:
* the session is interactive (not batch, cron, anacron, or at);
* it's a direct login from the login screen, not an "su" connection.
How do I do that in my .bash_profile? That is,
if [ what goes here? ]; then
How do I, within the .bash_profile if test, distinguish su connection
vs. direct login from the login screen?
I have a fedora30 desktop with Thunderbird 68.1.1 (64-bit), although
I'm not sure the version matters. It's configured to connect using
IMAP to a dovecot system also on fedora30.
The problem is that when Thunderbird is open on multiple computers
(the other is my Windows laptop), virtually every message received is
I'm not entirely surprised, considering two systems are competing for
the same connection. However, this doesn't happen with my K-9 client
on my phone with Thunderbird also open on my desktop.
Perhaps someone knows of a Thunderbird or dovecot setting that maybe
closes the connection when it's done updating, or some other
configuration option that prevents this?
I reported this at the time I upgraded my two systems to F30, and find
that it's still true with F31.
On my main (desktop) machine, there are two users, one of which (me) is
flagged as the administrative user; the other is a mere mortal. My
userid was displayed on the Gnome login screen; the other accessible by
clicking the "Not shown" link on the screen.
After the F29->F30 upgrade, the order of the two users was reversed,
with the non-admin user displayed by default. My own account is
accessible via the "Not shown" link.
This has not changed after my in-place (via dnf) upgrade to F31. The
secondary, non-admin user is displayed as the default login on the login
On my other system, a laptop, there was only one user account created
prior to the F29-F30 upgrade. When I ran the F29->F30 upgrade and
rebooted, I was FORCED to create a (new) admin user account, despite
there being one admin user already there. The new user now appears
first on the Gnome login screen; the existing user is accessible, again,
via the "Not shown" link.
This did not change after my in-place (via dnf) upgrade to F31. The
newly-created userid is displayed as the default login on the login screen.
While the extra click on "Not shown" is not a major big deal, I'm unable
to figure out how to flip-flop the two userids on the systems so that
the primary user appears on the login screen.
Suggestions/discussion welcome. Thanks.

I'm now running fedora 31 on my system at home and at
work. On both systems I occasionally notice all my
xinput settings have reverted to default, as if I
unplugged my mouse and plugged it back in (even though
I didn't unplug it).
Has anyone else noticed USB weirdness like this? Looking
at dmesg, that seems to be what the kernel thinks

Looks like a little less than 8 hours after the booted,
the kernel decided I just disconnected and reconnected
I have no idea what an EMI is, but that's what starts everything.
