With "Meta" key, do you possibly mean the <AltGr> / <Right Alt> key?
I see in bug #1872319 that you use the "English (Colemak)" layout (where <Righ Alt> is used by default to access 3:rd and 4:th level symbols), but the underlying layout used by ibus-unikey is "English (US)" (which does not make use of <Right Alt>). ** Changed in: ibus-unikey (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872325 Title: Cannot press Meta key when being used as input source To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ibus-unikey/+bug/1872325/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
