​All Korean keyboards, including the one on my LG Gram (which is a Korean model), have a dedicated key for switching between English and Korean (the "한영키"). Everyone who isn't technically inclined uses this key. Using Ctrl + Space is a bad user experience.

I don't think I've seen a single distro that ships Korean support right off the bat, except HarmoniKR. Because of the way Korean works, it's not just the keyboard layout support you need. To list the things you need to do:

• Install Fcitx5.
• Install Korean Fcitx5 input method. Probably named something like fcitx-hangul. Without it, Hangul keyboard will not appear in Fcitx.
• Check what 한/영 key really does. This is necessary because depending on the hardware, it either emits Hangul key, or Right Alt. If it emits Hangul, then you can skip this. If not, make sure you remap Right Alt to Hangul, because then the key triggers Alt action every time language is swapped. Those usually steal input, so it is really annoying.
• Add both Hangul keyboard (not Korean) and English keyboard in Fcitx5 config. Korean keyboard does not enter Korean characters. It's the Hangul keyboard that actually enters Korean characters. It probably corresponds to Korean keyboard's English input. It should look something like this.
• Add Hangul key as Enumerate Input Method Forward option in Fcitx config under Global Options tab.

I will attach my files in ~/.config/fcitx5. These two should go under that directory, and not ~/.config/fcitx.

Just a heads up, I havent looked into it for a year, but back then CJK input was completely non functional on wayland.

Ok apparently there has been progress.

At the beginning of this year it was working, even if a bit buggy, according to this talk. The talk also provides a good overview of all the subsystems involved.

Re: cinnamon: This guy has some videos on how to set up multiple keyboards and set a shortcut to change between them.

Can't speak to hamonikr.

Best of luck and remember that there's always a learning curve with these things

I've tried two different setups for Hangul input.

The first combination (GNOME+X11+IBus) just worked—it was trivial to setup from the GNOME Control Center and there were no issues that I could find. Last time I tried this was around a year ago but it had been working for years before that.

The second combination (Plasma+Wayland+IBus) barely worked: I could enter characters but couldn't add space or other symbols between characters, and settings were all over the place and would randomly stop working. Last tested ten minutes ago.

I've heard people getting better results on Plasma+Wayland+Fcitx5 but it's not something I've tried.

Now, Mint should support the need decently enough, although it takes some setup. You can look up for language setup settings, I found that fctix works well nowadays.

안녕하세요!

i personally use slackware, nabi for xim imhangul-gtk2/3 for gtk and qimhangul-qt5 (peremen) for qt. meaning i don't have korean input for qt6 or gtk4.

ibus kinda seemed to work but had numerous glitches, same for fcitx but worse, uim made gtk2/3 programs hang. i'm honestly not sure how other korean users are doing it. i've heard good stuff about harmonikr, but not entirely sure how it's much different from debian ubuntu etc.

also ensure xkeyboard layout is korean and the Hangul key doesn't identify as Alt_R in xev, some IMs don't like it.

I think KDE Plasma supports just about every keyboard layout in existence. It even supports the Esperanto layout, which I have never seen before. Pick a distro with Plasma and choose the right layout during setup.

That depends on your preferences

Just to be the annoying person and point it out: it's Linux. Not windows. So things will feel weird or strange, for you (and the wife) will be learning a new OS. Give it time.

Red star OS is best OS for democratic peoples Republic of Korea!

By the way your next generation is going to be 34% the size of your current one. You guys got to take some time off work.
