Can't repeat key input in Firefox

[xuzhao9]

How to reproduce:

1. On Firefox, open google.com and focus on any input or textarea element
2. Press the "d" key (or any key) and hold it down for 3 seconds

Symptom:
Only single "d" letter appears in the input box.

Expected behavior:
Repeating "d" letters should appear in the input box.

The bug only occurs with Firefox+Fcitx5 combined, as shown in the following video:

The bug disappears on Chromium+Fcitx5:

I have found a workaround:

export GTK_IM_MODULE=fcitx
export XMODIFIERS="@im=fcitx"
firefox

This is because firefox only detects "fcitx", not "fcitx5" in its IMContextWrapper. Closed.

I have encountered the same issue.
Thanks for posting this issue and the work around.

Every time I install fcitx5 onto a new machine (Manjaro Linux), I always have to add the following lines to my ~/.bash_profile because of this problem; without it I cannot use fcitx5 in my most important applications like Firefox or Kate (KDE text editor).

# fcitx5
export GTK_IM_MODULE=fcitx
export QT_IM_MODULE=fcitx
export XMODIFIERS=@im=fcitx

Is there no way to ensure this happens automatically? Or is this not fcitx5's fault but the fault of other applications. It would be really convenient if manual user intervention wasn't necessary.

do you have fcitx5-gtk installed? @dextertd

[dextertd]

Yes I do @wengxt I always install the following packages for fresh systems

fcitx5
fcitx5-configtool
fcitx5-chinese-addons
fcitx5-gtk
fcitx5-qt

[wengxt]

ah, sorry ; I was confused by the report title and I was thinking that you’re saying you having the same issue.

Yes it’s certainly possible that fcitx install a /etc/profile.d, or /etc/environment.d to set it up, but for setting this environment variable different distribution has their own way doing this. Actually even bash_profile won’t work globally. Especially when there’s other frameworks around like ibus.

I just don’t like to be very intrusive to users system, so I never tried to set those environment variables for users in fcitx.

Oh sorry, I should have created a new issue. I misunderstood the original description. That's my bad.

Sure I understand not wanting to be intrusive. I hope you might consider it anyway, as the current situation makes for a less than ideal setting up process in Manjaro, and new users might not understand why fcitx5 is working in some windows and not others. Certainly, when I first installed it, I had to learn about what qt and gtk were before I understood the problem, and then I was able to find a working solution. It was quite a confusing problem. Of course, it was a valuable learning experience, but as a learner who just wanted to type Chinese it felt unnecessarily frustrating.

@dextertd for manjaro case, there’s actually an manjaro specific package called manjaro asian input fcitx5 sth(I don’t remember the exact name, but you can just search for fcitx5)

[xuzhao9]

I setup the following environment variables in /etc/environment and I never need to add it anywhere else:

GTK_IM_MODULE=fcitx5
QT_IM_MODULE=fcitx5
XMODIFIERS=@im=fcitx5
