Since I no longer had an icon for Steam in Gnome, I tried to reinstall Steam via pacman -S steam. That didn’t bring me an icon in the Gnome overview either, but that was because I had created a separate *.desktop file in ~/.local/share/applications. I removed this and the icon in the overview came back. But now I have the problem that the games I call up via Steam no longer start. For one game, the launcher starts, but then displays the message “Please start Steam first” (Steam is already running, otherwise I wouldn’t be able to start the game). Other games bring up the message that no wine-mono is supposedly installed. But it is installed.

A reinstallation of Steam has not changed anything. What can I do?

    If I interpret the wiki correctly, it is only takes effect when removing groups. If you remove a group and some of those packages are dependencies of another installed package, you get an error. The -u or --unneeded flag strikes those needed packages from the list and removes only the unneeded ones.

    Edit: I just looked at the man page for pacman. There appear to be other usages besides groups. It probably does the same as with groups just with explicitly stated packages.

    -u, --unneeded

    Removes targets that are not required by any other packages. This is mostly useful when removing a group without using the -c option, to avoid breaking any dependencies.
