Fedora 37 qemu/kvm Centos 8 virtual machine Problem
by Robert McBroom
Installed CentOS-STREAM 8 ON A QEMU/KVM virtual machine. Initially the
reboot went only to a blank display. Editing the grub menu to give a
terminal boot was successful.
Succeeded to get a graphical screen with xinit and a terminal to
explore the options. Was able to install xfce for a graphical desktop
but gnome fails. The display managers gdm and sddm both fail with a
blank screen with the mouse cursor. The others lxdm and lighdm don't
show as being available.
How do I get the session to start properly?

evolution trash mail folder management
by Tim
Hi,
I was trying to find some info about how Evolution automatically purges
the trash mail folder, but haven't found any actual details. The
documentation is typically vague, barely saying anything further than
what you can see in the configuration preference windows.
I hate manuals which say things like "the delete button deletes the
message." I can figure that out, I'm not a moron, but the person who
thought that tiny bit of documentation (and no further information),
was adequate documentation, clearly was. Rehashing the GUI with a
couple of extra words is NOT instructional documentation.
Specifically, in the preferences (Evolution Preferences, Mail
Preferences section, General tab), you have a few options about
emptying trash folders, under the Delete Mail heading.:
On exit, every time
Once per day
Once per week
Once per month
Immediately, on folder leave
The first and last are completely obvious how they work, the middle
ones less so.
On other mail clients, I've come across options for purging old mail
depending on the age of the individual message (whether this be trash
folders or any other folder). This makes sense, you might want to keep
mail for 7 days (or whatever length), then purge it automatically. The
(user-defined) old mail disappears, the newer mail remains.
And Evolution does seem to offer purging options of that kind if you
right-click on individual folders, open their properties, and delve
into the archive tab (not where I'd expect to find deletion options).
That *would* be assuming that the delete option does actually delete
the message, rather than move it to the trash folder, but it does move
it to the trash folder. Though, if you go to the trash folder, and set
a similar purging option, it does actually delete the messages from the
trash folder (at least it doesn't delete messages in the trash folder
by sending them to the trash folder in an infinite loop).
If you want to manage the trash folder by right-clicking on it, and
setting some options, in a non-obvious place, you get reasonably
understandable results. But if you decided to manage the trash folder
by going through the main preferences, you have some oddball choices.
And that may have been the only place you thought to set options about
managing a trash folder, I know it was the only place that I looked for
a very long time.
The idea that on some unspecified time of day, day of week, or day in
the month, all mail in a folder will disappear, whether its been there
for 1 hour or 3 days, seems a particularly stupid way to do things.
The concept of a trash folder is that there's the opportunity to
undelete a message. You might set it for a week, so that the trash
folder stays small, but you can get a message back tomorrow that you
accidentally (or on purpose) deleted. But the list of options suggest
that you could delete a message, and it could disappear within the next
5 minutes, since once per month could be in 5 minutes time.
After that long ramble, my specific question: Has anyone discovered
*when* the once per day/week/month purges occur?

NB: All unexpected mail to my mailbox is automatically deleted.
I will only get to see the messages that are posted to the list.

MongoDB for fedora37?
by Alex
Hi,
I don't see mongodb in the default fedora37 repo. Anyone know where I might
find a maintained package? I've been using the one from centos7, I believe,
but it's dated and would like to find a more current version.
Thanks,
Alex

37 systemd pulseaudio paradox
by Felix Miata
Can anyone reconcile the following?
# journalctl -b --no-hostname | grep pulse
Mar 06 01:38:45 systemd[577]: pulseaudio.socket - Sound System was skipped because of a failed condition check (ConditionUser=!root).
Mar 06 01:38:45 systemd[577]: pulseaudio.service - Sound Service was skipped because of a failed condition check (ConditionUser=!root).
# systemctl cat pulseaudio.service
No files found for pulseaudio.service.
# systemctl cat pulseaudio.socket
No files found for pulseaudio.socket.
#
How can a condition be checked and fail if there are no such files connected to a
service or socket checked?

Evolution as taught in public schools is, like religion,
based on faith, not based on science.

Lots of the time, UPSes and generators are not actively monitored and
tested. An untested backup system is not a backup system, it's just
another point of failure! I have seen failures of big UPSes,
generators, transfer switches... you name it, even if it is "redundant",
it can (and will) still fail.

Relying on untested and unmonitored infra is a recipe for disaster. Also, check if you can use the backup: try a restore…
A customer once used the same media for a backup needing several media… 🫢😂

Chattering Keyboard?
by Tim Evans
$ uname -a
Linux osprey 6.1.15-200.fc37.x86_64 #1 SMP PREEMPT_DYNAMIC Fri Mar 3
17:29:44 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
Looks like I have a chattering keyboard. Idle terminal looks like
someone's repeatedly hitting <ENTER>. Ditto on virtual terminal.
keystrokes being duplicated in graphical apps like Thunderbird. Pace of
the extra stuff seems random. Sometimes it goes 20-30 seconds; others,
just a few seconds.
Don't see any journalctl ofutput of interest. Other than going out to
find a new keyboard, other suggestions welcome. Thanks............
