How to choose input method on Kubuntu 18.04?

Question

I have a new fresh Kubuntu installation. I have used Linux Mint and Ubuntu before, those OS have GUI settings for input method, where I can choose ibus or fcitx and type Vietnamese (my language, we use ibus-teni to type Vietnamese).

I did install ibus-teni, I can run ibus from Search tool, but couldn't type Vietnamese. So how do I setup the input method from default to ibus? Why does Kubuntu not have GUI settings for it like Ubuntu?

Solution 1

This happens when the ibus-daemon does not start automatically after booting into Kubuntu. Do the following steps to rectify this:

• Type 'Autostart' in Application Launcher search bar. This will open the 'Autostart System Settings' dialog.
• Now click 'Add program' button.
• Click 'Open file' button next to the search bar.
• Go to Root -> usr -> bin directory.
• Type 'ibus-daemon' in the 'Name' textbox.
• Out of the three options appearing in the list, select 'ibus-daemon' and click 'Open' button.
• Now you should be back in 'Autostart System Settings' dialog with 'ibus-daemon' selected under Desktop File category.
• Select the 'ibus'daemon' and click 'Properties' button.
• In the properties dialog, open 'Applications' tab.
• Type 'iBus Daemon' in the Name textbox and type /usr/bin/ibus-daemon start in the Command textbox.
• Now click 'OK' to come back to Autostart System Settings and click 'OK' here too.
• REBOOT YOUR MACHINE. (VERY IMPORTANT)

Your iBus daemon shall now start automatically and you shall see the 'EN' icon in the panel where you can click and select the language of your choice.

Solution 2

I think there is an Input Method Configuration GUI tool on Kubuntu, from where you can set IBus.

If you don't find it, you can also do it from command line:

im-config -n ibus

Unfortunately after running that line and launch ibus manually (yeah, I have to go to KDE launcher and search for "ibus" and run it), I still can not type Vietnamese.

Oops! After a restart, now I can type Vietnamese! But there is no icon of ibus showing which keyboard I'm using.

@Feliks: Hopefully some Kubuntu user can give you a hand about the icon.

This should not be the accepted answer as it is only half the equation, the answer is the one offered by Sachin below.

This should be the accepted answer! KDE should do this by default, not sure what it doesn't work
