Just stumbled upon this issue: https://github.com/ibus/ibus/issues/2130
Common denominators are: * Error in ~/.XCompose * Upgrade to ibus 1.5.21 ** Bug watch added: github.com/ibus/ibus/issues #2130 https://github.com/ibus/ibus/issues/2130 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ibus in Ubuntu. https://bugs.launchpad.net/bugs/1849399 Title: ibus in 19.10 misinterprets ~/.XCompose, somehow maps to the Delete key Status in ibus package in Ubuntu: Triaged Bug description: After upgrade to 19.10, I found that my Delete key was not working as a Delete key, but that instead if I hit Delete twice it would print the character ☭. Since others were not reporting this issue, I had a look around at my input config and remembered that I had ibus configured from a long time ago in order to support Chinese input. If I disable ibus (either by unsetting the environment variables; or by killing ibus-daemon), then the Delete key works again as expected. This is a regression in behavior since Ubuntu 19.04, where I had the same input setup on my desktop but the Delete key worked without problems. I'm also not sure how to disable ibus, now that I am in this situation; or if ibus is expected to always be running. The problem persists if I run ibus-setup and remove Chinese SunPinyin from the list of input methods, leaving only "English - English (US)".
