I am developing a Qt app in Fedora 31 using the default GNOME wayland session and I am very sorry to see the state of Qt in this configuration.
1) qt creator crashes often (https://bugzilla.redhat.com/show_bug.cgi?id=1773356) the crash report tool does not seem to help
2) drag & drop does not work in Qt creator (and in no other Qt app) (https://bugzilla.redhat.com/show_bug.cgi?id=1774762 and https://bugreports.qt.io/browse/QTBUG-80303)
3) main window geometry cannot be restored when the application restarts (https://bugreports.qt.io/browse/QTBUG-80612)
I think GNOME / Wayland / Qt it is just not ready and should not be offered as the default desktop session for Fedora.
If I force Qt to use X11 emulations, things are much better.
Probably Qt is responsible (but in the bug reports someone says that KDE / Wayland works well), and GNOME is not Qt, but there are so many Qt apps, that sending new users to a non working environment re-enforces the fact that "just works" is not true in Linux.
Last week, I was to participate in a "Zoom" meeting for a charity that
I'm involved in. I have the needed software on my rarely-used windows-7
box. But I could not complete the windows-7 login (some problem with a
windows-7 service). I've since found there is a "Zoom" client for
Fedora. "dnfdragora" does not find anything for it. But I found a web
page that I hope has what I need. I've downloaded the package
("zoom_x86_64.rpm"), and I've downloaded a "Public Key"
("package-signing-key.pub"). The web site from which I've downloaded
these also has a line:
Key fingerprint: [some 40 hex digit number]
1. Do the 2 files need to be in a specific place to do the install? If
2. Do I need to be "root" to do the install?
3. What do I do with the "Key fingerprint"?
4. How do I do the install (preferably using "dnf")?
Something on sourceforge has been recommended to me, but I try to
stick to things that dnf can install. Surely there must be some Fedora-
native ebook reader!

Remember I know little (precious little!) of where up is.
I have just upgraded to F31 from F30 using dnf system-upgrade
download --releasever=31. Before I did the upgrade I updated F30 to the
latest maintenance level.
When I booted into Gnome on F31 there was no activities menu to be
able to launch any application, the only way I could launch applications
(if I knew the application command) was to use alt-f2.
In F30 I was using dash-to-dock but in the F31 upgrade that failed
to start. I did find an entry on the net saying that V66 of dash-to-dock
had an issue in F31 with kde (plasma) but no reference to issues with
Gnome. I was able to run Gnome-tweaks, see that it was flagging that it
couldn't start dash-to-dock, the dash-to-dock settings were saying that
it was V66, so I used gnome tweaks to uninstall it. I then used
dnfdragora to install V67 of dash-to-dock when confirmed the V67 was
installed and V66 wasn't, but when I went back into gnome-tweeks it was
still saying that it was trying to start V66 of dash-to-dock. I
eventually found that I had to remove all the gnome-shell extension
settings in my home path, use dnf to uninstall dash-to-dock V67 and
reinstall it for Gnome-tweaks to show that it was successfully able to
start dash-to-dock V67. Also after doing this when I launched firefox it
immediately asked me asked me if I wanted to update all my extensions
from upstream except for dash-to-dock, which I did and that then
activated all the extensions even though at update they weren't active.
When I launch firefox V73.0a1 it displays with two windows
overlapping each other displaying the same contents, forms being
displayed on the screen are not displaying correctly in terms of when
input is entered into text boxes the input is actually being displayed
below the text boxes. Also the address bar keeps flashing on and off
because the display of the web page being accessed is intermittently
overlaying the address bar, consequently I can't actually select any
menus displayed on the web page. Just for interest Thunderbird V73.0a1
doesn't seem to exhibit these issues. If I run the version of firefox
from the repositories it exhibits the same overlay issues as well.
When I run Gnome-terminal it exhibits the dual window overlay issue
when maximised. If I run Gnome-terminal unmaximised it doesn't exhibit
the issue, but if I manually expand the size of the gnome-terminal
window it exhibits the overlay issue as soon as I type anything into the
I tried reinstalling Gnome by re-installing the 'Gnome Desktop
Environment' group from dnf but that did not make any difference.
Does anyone have any ideas what the issue might be?
If I run dnf system-upgrade download --releasever=30 will that
downgrade me to a fully working version of F30 as it was before I did
the F31 upgrade?
I'm running Fedora 31/KDE and it is great. Fantastic, actually. Kudos to
the team that delivers and supports Fedora, release after release. Things
just keep getting better and better and the update process is so smooth and
easy. Especially compared to those other operating systems...
However, F31/KDE isn't perfect. Here are a few things that could be
1) There is a bug that creates distortion in playing audio via HDMI
monitors. I frequently have to do a pulseaudio -k to reset things.
2) There is a bug when running dual monitors and the left monitor is
rotated and not the primary monitor. I have to start SystemSettings and
force a reinitialization every time I reboot.
3) There is a bug wherein the HDMI monitor I want my audio played on isn't
saved. It always wants to play on the first (left most) monitor. I have
to start pauvolume and select my primary monitor every time I reboot.
4) It would be really, really nice if KDE remembered which desktop an
application was on when you rebooted after doing a forced shutdown. For
example, sometimes I have 30 Firefox browsers open on various topics,
spread across 3 or 4 desktops, plus some PDFs in viewers and a few Konsole
sessions and a few Kwrite documents... and a large update comes along that
I need to apply that requires a reboot.
Generally I do a #dnf update followed by a #shutdown -r now.
When I reboot and login to a new session, Firefox allows me to restore all
my open browsers, but it doesn't remember which Desktop they were on... so
I have to manually sort them. Likewise Konsole sessions don't remember
what Desktop they were in, nor the path they were open to. Would be nice
if they did.
5) There is an unintended behavior whereby if I open a document fullsize on
one screen, it goes fullsize on any screen I move it to.
For example, I run a 22" monitor in portrait mode to the left of my primary
43" 4K monitor. I often fullscreen a document in the side monitor to
refer to while I am working on something on the primary monitor. If I
then drag the document from the side monitor to the primary 4K monitor, it
goes fullscreen there. And then I have to resize it. It would be nice if
it stayed the same size, pixel wise, when it moves from screen to screen.
6) My mouse doesn't move enough...
My desktop is very wide. A side 1920x1080 monitor running in portrait
beside a 4K monitor. I have my mouse speed/acceleration turned right up,
but I often run out of space on my mouse pad before I can move across or
even up and down my desktop. It would be nice if there was more
speed/acceleration so less hand movement was required.
Enough of the negative... how about some things I absolutely love about
1) Putting a panel anywhere I want ! When you've got this much screen real
estate, you need several of them.
2) Multiple desktops. OMG, I could never live without multiple desktops.
So nice to be able to sort tasks into desktops and then jump from desktop
to desktop to handle things.
3) The way task manager groups and displays apps in the panel. So nice...
but... I wish there was a way to sort and search instances within a task
list... like if I have 7 Firefox browsers open on a desktop, be able to
arrange them in a certain order (gmail at the bottom, for example) or find
all the browsers that have YouTube open in them. That sort of thing.
4) dnf update. Dnf in general. Has there ever been such a great package
manager ? I can remember complaining going from Yum to DNF, but I was
I love how I'll get a desktop notification for updates, I can run dnf
update (when I want), view what is available, stop the update, update
select packages, etc. Updates work around me, I don't have to work around
updates. And the update process is unobtrusive, it can generally run in
the background without interrupting my work. (On a faster multicore
5) Konsole. I love me some Konsole sessions. Especially the way you can
right click and open Dolphin in the directory you are working in from
Dolphin. And especially how you can open Konsole from Dolphin.
6) The stability.
I can start work on Monday and run all week without rebooting or even
logging out. My computer never freezes or stumbles or loses data. It's
fantastic. I never have to reboot and get organized again. I work. I go
away. I come back. And everything is just the way I left it.
7) The ability to mount just about any file system ever.
I'll leave it at that. To say I am enjoying and appreciating
Linux/Fedora/KDE these days is an understatement.
When I look at /var/log/secure or run journalctl on my workstation, I
see failed SSH login attempts from a variety of IP addresses. The
attempts are every 3-12 minutes.
The workstation is on a LAN behind an EdgeRouter firewall. No Internet-
accessible ports are forwarded to the workstation. The LAN has a
variety of servers, NAS boxes, WiFi access points, WiFi-connected
A typical /var/log/secure entry looks like this:
Jan 30 12:43:50 redwood sshd: Invalid user jackiehulu from
18.104.22.168 port 37394
Jan 30 12:43:51 redwood sshd: Received disconnect from
22.214.171.124 port 37394:11: Bye Bye [preauth]
Jan 30 12:43:51 redwood sshd: Disconnected from invalid user
jackiehulu 126.96.36.199 port 37394 [preauth]
The corresponding journalctl is:
Jan 30 12:43:51 redwood.eagercon.com audit: USER_ERR pid=21228
uid=0 auid=4294967295 ses=4294967295
grantors=? acct="?" exe="/usr/sbin/sshd" hostname=188.8.131.52
addr=184.108.40.206 terminal=ssh res=failed'
I'm assuming that something on the network has been compromised,
allowing SSH login attempts on the LAN. Other than turning off
each server/AP/laptop/etc, one at a time, to find when the accesses
stop, is there any way to find out where the SSH attempt is coming from?

My new computer has got 2 disks: a SSD and a HDD one.
The SSD disk is large enough to have Fedora and my entire home
directory on that.
Now, I am intending to use the HDD disk for backuping. And my question
is: How should I format the HDD disk?
Thanks in advance,
This might be way off topic, but I figured this is a kind of slow day!

Can anybody with a Ryzen CPU + ECC memory show me the output of
# dmesg | grep ECC
I am buying a Gigabyte X470 AORUS GAMING 7 WIFI in order to be able to
use ECC capabilities, by the way Gigabyte documentation states: " ECC is
only supported with AMD Ryzen and Athlon of PRO-series CPU."
The problem is that PRO versions are OEM only, so I am wondering if I
can use ECC capabilities with a regular Ryzen CPU...
