dnf -y install gnome-extensions-app
then (call extensions in super search, or just from the shell gnome-extensions-app)
What a waste of an effort in the morning! :(
Install with the dnf package and then missing libraries
sudo dnf install webex
sudo dnf install xcb-util-wm libxcrypt-compat sqlite-devel

- autoremove - removes packages installed as dependencies that are no longer required by currently installed programs.
- check-update - checks for updates, but does not download or install the packages.
- downgrade - reverts to the previous version of a package.
- info - provides basic information about the package including name, version, release, and description.
- reinstall - reinstalls the currently installed package.
- upgrade - checks the repositories for newer packages and updates them.
- exclude - exclude a package from the transaction.
Complete command reference: https://dnf.readthedocs.io/en/latest/command_ref.html
- which package provides a particular command:
dnf provides command - what particular binaries does a package provides:
dnf repoquery -l libgnome|grep bin/(reference: https://discussion.fedoraproject.org/t/dnf-command-to-show-what-cli-binaries-tools-a-package-provides/76774) - How many packages are installed :
sudo dnf list(good read: https://www.networkworld.com/article/970056/looking-into-installed-packages-on-fedora.html)
- Open dconf-editor
- Go to org/gnome/desktop/wm/keybindings
- Move the value 'Tab' from switch-applications to switch-windows
- Optionally move 'Tab' from switch-applications-backward to switch-windows-backward
- If you want switch-windows to work across desktops, not just in the current desktop, you can also uncheck org/gnome/shell/window-switcher/current-workspace-only (Courtesy of @CharlBotha)
- Close dconf-editor
- If using X11, press F2, then type r to restart Gnome.
The last step does not always appear to be necessary, but it should not hurt (especially since it does not close any of your running applications). It will not work, and is not necessary for Wayland.
"gnome-terminal" is the name of the application to put.
install dconf-editor tool and edit the following property: "org/gnome/desktop/wm/preferences/focus-new-windows"
You need to set PS paths, which are not set by default in Fedora (very short .bashrc script).
- Copied the Ubuntu default .bashrc script in the home, https://gist.github.com/marioBonales/1637696 (update: the NUC bashrc : https://gist.github.com/animeshtrivedi/34959ec6ba9f60be79eb1d9b2168774d)
- Changed the color profile to the following, Back-on-Light-Yellow with Tango scheme
Default .bashrc
atr:~$ echo $PS0

atr:~$ echo $PS1
\u:\W\$
atr:~$ echo $PS2

In fedora this is the wheel group that has the sudo powers (in Ubuntu it is called sudo group) : https://docs.fedoraproject.org/en-US/quick-docs/adding_user_to_sudoers_file/
$ sudo usermod -aG wheel username
$ sudo visudo
...
%wheel ALL=(ALL) ALL
...
Update for no password (there is already a separate line to comment/uncomment this option in the sudo user file):
%wheel ALL=(ALL) NOPASSWD: ALL
They are in settings -> Applications --> Default application
The usual sudo update-alternatives --config editor did not work as it showed no output.
With that (1. install a new default editor package, and then remove nano). With that now sudo visudo has the vim as the default editor. I also have $EDITOR set in the .bashrc file. source
atr@cordova:~$ sudo dnf install vim-default-editor --allowerasing

This is the recipe for building the DisplayLink driver in a RPM package for Fedora, CentOS Stream, Rocky Linux and AlmaLinux OS. This driver supports the following device families: These instructions work
DisplayLink RPM : https://github.com/displaylink-rpm/displaylink-rpm
Go here, and then download from the releases: https://github.com/displaylink-rpm/displaylink-rpm/releases/tag/v6.0.0
This is the one I use: https://github.com/displaylink-rpm/displaylink-rpm/releases/download/v6.0.0/fedora-40-displaylink-1.14.4-2.github_evdi.x86_64.rpm

- launch web browser
- reset terminal
- workspace shift
- move windows between workspaces
