Christopher M. Penalver, for all that is worth, I reported that this bug affects me as well, but following some system upgrades, it seems to be solved now.
This problem did not occur in an Ubuntu release prior to 16.04, on my system. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1613025 Title: Lock screen doesn't allow to switch language Status in xorg package in Ubuntu: Incomplete Bug description: I have English and Hebrew languages on my computer, and to switch between them, the key binding is alt+shift. When my system is on the lock screen (not the switch account screen, lock screen), sometimes I can't switch languages. I'm trying to switch from Hebrew to English to type in my password, and when I hit alt+shift, the lock screen suddenly disappears, and I see my screen for a second, then my screen goes black for a second, and I go back to the lock screen. The language is still on Hebrew, and I still can't change it to English. WORKAROUND: Change the language using the mouse, or to hit "switch account" with the mouse and then I can log back in.
