I have Ubuntu 18.04.3LTS installed on my computer.

Trying to install a Korean keyboard, I first followed this answer, which didn't work, then I installed Fcitx according to this answer. After rebooting and configuring the Language Support, I switched the keyboard to Korean and the screen froze. I still had control over the mouse cursor, but the environment didn't respond.

After rebooting, the screen gets stuck indefinitely on the splash screen.

Following advice from this answer, I booted in recovery mode and ran sudo fsck -f /, which seemed to fail – even if I run the command multiple times as recommended, I keep getting the same error message (translated from French, so may not be 100% accurate): 

/def/sda2 is mounted
e2fsck: Cannot continue, immediate stop

Continuing the advice, I edited etc/default/grub and removed the silent splash options in order to troubleshoot further.

The boot process seems to go fine, every action is labled with a green [ OK ] and the process ends with this line:

[  OK  ] Started User Manager for UID 1000.

It makes sense this would be the last step in the boot process. After that, I can see and move the mouse cursor on screen, but not use it in any meaningful way.

What actions can I take to debug any further and possibly solve the issue?

I solved the problem, as I suspected the issue was linked to the installation of fcitx-hangul.

I opened tty using ctrl+alt+F2 and removed fcitx and its dependencies, and was able to boot without any further issue.

I have no further insight as to why fcitx crashes my system, but reinstalling fcitx-hangul crashed my system again as soon as I switched the keyboard layout to Korean, and then again on boot.
