Well, I went to the Fedora Kernel IRC, there the guys told me I can
ignore it and enjoy the performance benefits of a vulnerable SMT or
disable SMT and suffer the performance penalty.
I am just wondering if I have hit the zenith, you know, is there really
anything to be done anymore ?

Too Many Clicks
by Robert McBroom
In Xfce, I was looking at the settings for the mouse and clicked the
button to turn it off. Now the cursor sits in the middle of the screen
and I have very few options for control. A few pop ups with the
function keys but logout is the only useful one. Is there a key
combination that will activate the arrow keys to move the cursor so I
can pull down the menus and switch the mouse back on?

Errors in Classifying Updates
by John Mellor
The Gnome update tool classifies updates as things that can be
immediately installed, and things that require a reboot to install. I
have never seen an update requiring users to login again, but that
should obviously be a state transition that the Gnome updater should
occasionally need as well. Someone pointed me to the tracer package for
CLI use, and it seems to work well in detecting these missing dependency
issues. However, no such mechanism exists as part of a GUI update.
Much as I disagree with the Gnome devs about the incorrect rationale for
reboots on an inode-based system, I can see the need to do this without
the functionality of something like tracer, for badly-designed apps that
do not correctly identify their run-time dependencies that need
restarting to maintain system integrity.
Its relatively difficult to find packages that can be immediately
installed, and it only seems to be seen in actual practice in maybe
1-in-50 updates. Since (say) 80% of updates are not "system" updates,
this seems intuitively very wrong. Reboots due to updating should be
very rare. Instead, they are 95% of the updates in practice. Clearly,
something is wrong.
This morning I ran the GUI updater. There were updates available for
the vim-filesystem and vim minimal packages. However, they are for some
weird reason marked as requiring a system restart in order to install.
That just stumps me. How can Vim possibly be an update requiring a
system reboot?
So, is there a problem in the dependencies lists of the packages, or is
it a bug in the Gnome updater app?

trying to convert to nftables I have a problem that it adds rules
on its own
by D&R
nftable.conf is setup as:
flush ruleset
table inet nat {
chain postrouting {
type nat hook postrouting priority srcnat; policy accept;
masquerade random,persistent
}
}
table inet filter {
chain input {
type filter hook input priority filter; policy drop;
counter jump block
}
chain forward {
type filter hook forward priority filter; policy drop;
counter jump block
}
chain output {
type filter hook output priority filter; policy accept;
}
chain block {
ct state { established, related } counter accept comment "accept all connections related to connections made by us"
iifname "enp1s0" counter accept
iifname "enp2s0" counter accept
iif "lo" accept comment "accept loopback"
tcp dport xxxxx counter accept comment "accept SSH"
counter log prefix "IPTABLES IN= " level crit flags tcp sequence,options
counter drop comment "count dropped packets"
}
}
After it runs for a few minutes it adds the following at the bottom of the
table:
table ip filter {
chain INPUT {
type filter hook input priority filter; policy accept;
counter packets 214 bytes 18153 jump block
}
chain FORWARD {
type filter hook forward priority filter; policy accept;
counter packets 525 bytes 85145 jump block
}
chain OUTPUT {
type filter hook output priority filter; policy accept;
}
chain block {
}
}
I can't explain this, can anyone else do so?
Thanks,

Terminal bleed through?
by Christopher Marlow
What could cause this issue?
When I open a terminal in FC 32 I see bleed through of my wallpaper as
seen below.
https://imgur.com/a/EhaLRQu
See the line right up under the password prompt?
It will go away if you highlight the line with your mouse or type in
your password and hit enter. Its just kind of annoying to see.
I just had this start happening after I got this new monitor.
I didnt have this problem with the 17" monitor.
Thanks,

is this a dnf bug?
by Tom Horsley
I download updates to the cache on cron at night.
I wanted to apply some updates, but not have to reboot
because I got a new kernel or something, so I did:
dnf update 'libre*'
That updated all the libreoffice packages.
Then I look at the cache, and it deleted *everything*,
not just the libreoffice packages it installed.
Should it really work that way?

Thunderburd notifications -
by Bob Goodwin
°
Some time ago Thunderbird email notifications stopped happening and I
can't determine why. I have it set to provide both visual and sound
notification but neither happens. Thunderbird provides audio from
various sources but never for email notifications now and my effort to
troubleshoot has been unsuccessful. PA volume GUI displays nothing from
the sound test in preferences, however all other sources show up as
expected. The inner workings of Thunderbird are pretty much a mystery
and I don't know how to troubleshoot this any further. I had hoped it
would just begin working again with the new install of Fedora 32 but
that hasn't happened. I would appreciate any thought on what to try next?
Bob.

sound in KDE ?

This is probably just my imagination, but the sound in KDE when watching
YouTube, seems to be lower than my installs of Gnome and Xfce.

F32, XFCE desktop, pointer doesn't switch to "busy" image when launching apps
by Sam Varshavchik
The first thing I noticed after updating to F32 is that there is no feedback
from the mouse pointer when I launch apps from desktop icons; the mouse
pointer remains unchanged and does not spin, the "busy" animation, until the
app launches and opens its window.
It's a little UI annoyance, and makes for a slightly worse user experience.
Just to be sure I reinstalled the desktop icon fo Firefox. This had no
effect.
