Generally you only need an actual driver for a USB connected printer or scanner. My advice is that you look for a used HP or Brother laser printer (Craigslist/Kijiji). They last forever and are easily installed/handled by CUPS. Get one with a built-in network card, or find one *really cheap* and buy a network print server for $25-$30. The printer can be put somewhere out of the way (same with wireless capability). You can print directly from any computer or tablet or phone. The HP and Brother laser printers "just work". The laser printers can sit for weeks, using effectively no power but still available. If you only want 'basic' service, you should about what you really need and the footprint. I do not know how old my HP-1320 is, at least 20 years. It has a 14" square footprint. The HP-3055 MFD is "newer" at maybe as recent as 2006 (although that could just be the last software update date), much larger and obtrusive. I only keep it really for the scanner since I lent my Brother ADS-1000 scanner to my brother and it seems to have "disappeared" and cannot be found! If you only need scanning to make the odd photocopy, you might find a small standalone scanner will do the job. Much smaller footprint. The Brother scanners need the two free linux drivers installed but the website support is excellent. The ADS series are small, fast and good. G.

Does this show anything? And, I did try webm and it worked fine. IDK which is the smaller file, webm or mp4. I usually watch this stuff with vlc on windows or an OS using vlc. I tried ffmpeg -formats mp4 -i re.iso re.mp4, ffmpeg version 5.0.1 Copyright (c) 2000-2022 the FFmpeg developers built with gcc 12 (GCC) configuration: --prefix=/usr --bindir=/usr/bin

recommendations, pros/cons for Fedora mail clients supporting OAUTH2 with GMail?
by George Avrunin 21 Jun '22

21 Jun '22

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.

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 20 Jun '22

20 Jun '22

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, Mike Wright

deja-dup/duplicity in F36

Clean install of Fedora 36. Backups using deja-dup/duplicity now do not work, fine in F35 and many prior releases. sudo yum install deja-dup yields Package deja-dup-43.3-1.fc36.x86_64 is already installed. Dependencies resolved. Nothing to do. Complete! & (actually duplicity is in the dej-dup dependencies output list, but..) sudo yum install duplicity yields Package duplicity-0.8.23-1.fc36.x86_64 is already installed. Dependencies resolved. Nothing to do. Complete!

What package do I need to install for my Nvidia card
by Anil F Duggirala 20 Jun '22

20 Jun '22

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 19 Jun '22

19 Jun '22

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 19 Jun '22

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. Max Pyziur pyz(a)brama.com
