The issue is indeed due to ibus changes, see https://github.com/ibus/ibus/issues/1961
Basically they added an emoji picker (which you can start with "ibus emoji") and make that displayed with ctrl-shift-e (in 1.5.18) and deprecated ctrl-shift-u since that can conflicts with some applications keybinding. Updating to .18 would give us the new picker but not the old feature back, I'm pondering distro patching that simple change that has been proposed upstream bug rejected https://github.com/ibus/ibus/issues/1962 ** Bug watch added: github.com/ibus/ibus/issues #1961 https://github.com/ibus/ibus/issues/1961 ** Also affects: ibus via https://github.com/ibus/ibus/issues/1961 Importance: Unknown Status: Unknown ** Bug watch added: github.com/ibus/ibus/issues #1962 https://github.com/ibus/ibus/issues/1962 ** Changed in: ibus (Ubuntu Bionic) Importance: Undecided => High ** Changed in: ibus (Ubuntu Bionic) Status: Confirmed => In Progress ** Bug watch added: github.com/ibus/ibus/issues #1981 https://github.com/ibus/ibus/issues/1981 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ibus in Ubuntu. https://bugs.launchpad.net/bugs/1760308 Title: Unicode input not working on Bionic with CTRL-SHIFT-U Status in ibus: Unknown Status in ibus package in Ubuntu: In Progress Status in ibus source package in Bionic: In Progress Bug description: I need to enter Unicode with Unicode escape codes and the Ubuntu prescribed way is to use CTRL-SHIFT-U and then enter some numbers to input. This doesn't do anything in the Ubuntu Bionic beta. Potentially related the ALT-TAB window switching is delayed in recognizing the occurrence of the keys being pressed such that I have to hold ALT-TAB instead of quickly hitting both simultaneously. This is from a system that was upgraded from a previous Ubuntu version without any issues. Description: Ubuntu Bionic Beaver (development branch) Release: 18.04 The "Affects" package may not be accurate as I don't know what the cause application is for this.
