Heh. #Bodhi #Linux's native IME went weird and everything. Suddenly, it can only see one variant of a keyboard layout.
So, I tried to install #iBus again, play around with it (which I no longer remember what I did). iBus can type in Hangeul (finally, it didn't work before) but can't type in Baybayin for some weird reason (all xkb files are correct).
In the end, I mixed Bodhi's native keyboard and iBUS. Type baybayin, I switch keyboard through Bodhi's keyboard app; type Hangeul I switch keyboard through iBUS.
As much as I like Bodhi Linux, I'm not going to use this again because of this IME issue. For one, they shouldn't force people to use their native IME/keyboard app. I just can't find a way to make iBUS work properly, and it has been an issue since 2016/2017 as far search engine results are concerned, and no one found a “fix”.
Or maybe, it's not Bodhi's fault, but Moksha or Elementary. I don't know. This is why Gnome, is so popular, you have a choice and it just works.
