Did some testing on bionic. It appears to me as if the feature is designed solely for Wayland. Yes, on Wayland with GTK_IM_MODULE unset it seems to work without issues. On Wayland with GTK_IM_MODULE=ibus I can reproduce the issues as described above.
On Xorg the feature works very poorly irrespective of the value of GTK_IM_MODULE. Basically you can only type the characters you see on the first instance of the screen keyboard (which depends on the effective XKB layout). Capitalized letters get typed as small letters, and most extended characters don't result in anything or some wrong character. Considering that Xorg will be default in 18.04, would it be worth the regression risk to stop im-config from setting GTK_IM_MODULE this late in the cycle in order to fix the feature on Wayland? -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1761554 Title: [bionic] Extended characters in GNOME screen keyboard don't get entered To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1761554/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
