gdm3 switching keyboard input method does not take effect

tf flag

We recently upgraded our Ubuntu box to Jammy 22.04 LTS. Since its lightdm cannot work at all (screen hangs after start, no mouse, cannot type anything from keyboard), we switched to gdm3.

But after gdm3 login, we found that we cannot switch the input methods between normal English or Chinese Bopomofo. In the upper-right corner, we can use mouse to switch between English and Chinese input methods, but it does not take effect in the applications (like browser, terminal, ... etc). In all the applications they are still stick in English input.

Could anyone help us to solve this problem ? Thank you very much.

Cheers, T.H.Hsieh

After many trials and errors, we finally assumed that the ibus-bopomofo Chinese input method may have bug (for Ubuntu Jammy 22.04 LTS system). Therefore, we solved this problem by the following steps:

  1. Edit /etc/gdm3/custom.conf, to force the login screen using Xorg:
   WaylandEnable=false
  1. Install ibus-chewing Chinese input method to replace the ibus-bopomofo input method:
   apt install ibus-chewing
  1. Reboot the system. Then one can select ibus-chewing input method from Preference / Keyboard.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
