Mark, I searched for "input method" but I couldn't find anything relevant (at least not for me).
In Gnome Control Center -> Region & Language I have two Input Sources: Portuguese (Brazil) and English (US) In Input Source Options I have "Use the same source for all windows" checked. In Gnome Control Center -> Devices - > Keyboard -> Keyboard Shortcuts -> Typing Switch to next input source = Super + Space Switch to previous input source = Shift + Super + Space Patrick also suggested the problem was with the input method and mentioned the same issue with Japanese and that it could be the IM editor activated. I found 2 INPUT METHOD tools in the menu: Applications -> System Tools -> The first one (blue icon) opens the uim-pref-gtk. In the Global Settings there was a check box "Input method toggle" checked with Input method toggle key set to: "<Meta>space" I disabled it, but the behavior persisted. The second tool is the Input Method Configuration (im-config) It starts with the following text: "Current configuration for the input method: * Active configuration: missing (normally missing) * Normal automatic choice: none (normally ibus or fcitx or uim) * Override rule: zh_CN,fcitx:zh_TW,fcitx:zh_HK,fcitx:zh_SG,fcitx * Current override choice: (en_US) * Current automatic choice: none * Number of valid choices: 1 (normally 1) The override rule is defined in /etc/default/im-config. The configuration set by im-config is activated by re-starting X. Explicit selection is not required to enable the automatic configuration if the active one is default/auto/cjkv/missing." And after I went to the steps of configuration selecting the recommendations, it outputs: "Keeping the user configuration /home/myuser/.xinputrc as missing. Automatic configuration selects: none This does not set any IM from im-config. This is the automatic configuration choice if no required IM packages are installed. If a daemon program for the previous configuration is re-started by the X session manager, you may need to kill it manually with kill(1). See im-config(8) and /usr/share/doc/im-config/README.Debian.gz for more. Everything was working fine 1 week ago. I could type SHIFT + SPACE and a space character would appear. I just updated the system. Any more ideas? Thanks in advance. Regards.
