recommendations, pros/cons for Fedora mail clients supporting
OAUTH2 with GMail?
by George Avrunin
Since the late 1980s when I set up our department Research Computing
Facility, my department has managed its own email servers. We now have
extremely competent staff (not me!) who do great work dealing with spam,
phishing, etc., and I get much less spam on my math department account
than I do on, say, my account in the CS department, which uses a
commercial spam blocking service. But recently the pressure from
University IT to let them run all mail has increased to the point where
we're basically being forced to shut down our own mail servers and use
theirs, effective around the end of this month. I do need to continue to
access my university email, both for reading and sending through the
university's servers.
The university has decided not to allow any access to mail except
through Outlook and GMail, where authentication goes through the campus
2FA process, etc. The university IT people would much prefer that all
faculty and administrators use Outlook (they've generally tried to
outsource as much to Microsoft as they can, especially things with any
security implications--this gives you an idea where they're coming from),
but there's an option for GMail which almost all of our faculty have
chosen. But at least the GMail version requires support for OAUTH2.
According to the university IT people, the only options for accessing our
university mail on GMail without using Windows or Mac OSs will be the web
interface and the Android and IOS GMail apps. They do admit that
Thunderbird works, but they say it's "unsupported and may not continue to
work".
At present, I forward my university email to a department-supported machine
in my office running Fedora, where I run dovecot. I access mail from
various devices with IMAP, mostly using claws-mail on the Linux boxes
(where I mostly run Fedora with KDE) and FairEmail on Android. It looks
like they're going to make it harder (and probably officially forbidden) to
forward mail routinely. I also use claws-mail to read my personal GMail
account (which I don't use much, but need for some purposes), with an app
password on some machines and OAUTH2 on my main desktop. But using OAUTH2
currently requires setting up claws-mail as a personal development project
(in what Google calls the "testing" phase; the claws-mail code is not
"approved" by Google for "production") and regenerating the authentication
token once a week. I'd be happy to continue doing that and using
claws-mail, but it seems that my university account is locked out of both
app passwords and setting up a project. As far as I can tell, I won't be
able to continue to use claws-mail for my university email, at least
without forwarding it in explicit violation of policy.
I have made sure that Thunderbird can connect to my university account,
despite the dire warnings from the university IT people. (And FairEmail
also seems to work fine for this on Android.) But the last time I tried
Thunderbird, admittedly a fair while ago, I wasn't very happy with
it--heavyweight, oriented toward HTML mail, opened too many links, etc. In
the distant past, I mostly used email within Emacs (rmail and then vm) and
I once looked at Evolution but again wasn't happy with how big it was and
how much it seemed to pull in. I generally have been pretty unhappy with
the web interfaces to email that I've tried, though I haven't spent much
time in the latest incarnation of GMail on the web.
So I'm looking for other suggestions about what might work, including more
up-to-date views of Thunderbird, Evolution, etc. Thanks for any other ideas
or comments.

ffmpeg
by Bill Cunningham
Does anyone used or has anyone used ffmpeg to convert iso to mp4? I have
looked at the documents and they explain how to do everything but what I
want to do, so it seems. I do use CLI. That is the only command I know
that converts from CLI.

[OT] mystery character
by Mike Wright
Hi all,
Since this list has got to have one of the most diverse user sets out
there I thought to ask this here.
While watching a youtube presentation about CSS I came across a selector
using a character that I don't recognize and can't copy/paste since it's
in a video so I screenshotted it.
Here it is: http://tinyurl.com/bp9crbnv
Anybody know what it is or what language it is from?
Thanks for any help,

What package do I need to install for my Nvidia card
by Anil F Duggirala
Hello,
I have read part of the https://rpmfusion.org/Howto/NVIDIA guide to
know how to install proprietary drivers for my Nvidia card. My laptop
comes with a regular Intel Graphics card alongside an Nvidia Geforce
GTX 960M card. I am on Fedora 36, Gnome (Wayland).
I don't want to mess up my system, so I just want to ask; what is the
simplest procedure install drivers for this card on my system?
When these drivers are installed, will I still be able to do regular
work with my Intel card and launch specific applications (games) with
the Nvidia card?
My card supports CUDA and Optimus.
Do I need to disable Secure Boot?
Note: I have already enabled the free and non-free RPM fusion
repositores. I know there is a specific rpmfusion Nvidia driver
repository, do I need that also?

screen won't un-blank under specific timing
by Fulko Hew
I just had it again, it's very rare.
And it's happened over the last number of Fedora versions (-1 to -n)
If I come back to use my computer and hit a key at exactly the same time
as the screen decides to blank (I don't use screensavers) then the screen
does blank, but no key or mouse activity (I've tried) will cause the
screen to wake up again. I know the machine is still active because one of
the keystrokes I tried, woke up and started to play a Youtube video that was
paused on one of my browser instances.
So everything is still working, but nothing (I've found) will un-blank the
screen.
Idea's anyone?
[It's hard to replicate, but I seem to be able to time it right/wrong
every few months.]

gthumb - animated/moving gifs not showing up in browser
by Max Pyziur
Greetings,
I have a number of moving gifs in my various photo/image collections, all
with Tags.
As of some recent upgrade (or possible misconfiguration), they have
stopped showing up.
I can still view them using something like eog; but I've defaulted to
gthumb.
Much thanks for any advice.

Getting a new printer/scanner
by andreas.fournier＠runbox.com
So, it's time again for me to get a new printer/scanner as the old one
just died.
I hope it isn't too much off-topic to solicit advice on what to get so
that it would work flawlessly with Fedora. I'm looking for a rather
basic model. When I browse the homepages of manufacturers I can't find
any mention of support for Linux. Is there a list somewhere of
printer/scanners that are supported by Linux?
Thanks
