Cannot change input method in snaps

snapd
1

I am not able to write in japanese through fcitx+mozc input method within snaps.

Example of snaps with this behavior: discord, simplenote.

2

I have just tested this with libreoffice snap.
Same issue - cannot change input method.

This is a serious limitiation, CJK languages have a fairly large userbase.

Any chance for fixing this?

Do you see any security denials at the time of the failure? Eg:

$ sudo journalctl | grep audit
4

journalctl is full of these:

I should’ve had you filter out the STATUS messages, but I don’t see anything in the denials that is blocking using fcitx or mozc specifically. The unity7 and desktop-legacy interfaces are intended to be used with these input methods. I suspect is it something wrong with the snaps (perhaps in the desktop-launch provided by the snapcraft desktop parts).

6

This denial is unrelated to fcitx+mozc AFAICT, but is interesting to me. Can you describe ‘font-manager’, how you installed it and how you are using it?

7

@kenvandine or @jamesh - I wonder if this is something that you or someone from the desktop team can investigate?

8

I have font manager installed, through official repos iirc. I do have several fonts in my ~/.local/share/fonts folder, maybe that’s why?

@jdstrand
hi, any new info on this? I am now testing newest libreoffice snap, and the issue persists

10

I believe that ~/.local/share/fonts is now handled correctly by the desktop interface, but this shouldn’t have anything to do with fcitx.

@oSoMoN is looking at fcitx in this other thread: Can't use input method in snap apps
