I installed the ibus input method via yast in openSUSE 15.0 Stable
Distribution. I have a normal configuration, no packages or unknown
repositories in my system except for Pacman and Libdvdcss (or whatever that is
called). Ibus works on the text editor, on other applications, just not on
these. It was working ok before, ibus and fcitx before had problems working in
certain snapd and flatpak packages but never on those coming from the official
sources of openSUSE. All my workarounds, restarting the daemon, restarting
ibus, restarting the system, did not work. Fcitx on the other hand works fine,
but I prefer ibus because it is easier to use with multiple language input.
