You have been subscribed to a public bug: On Ubuntu 16.04:
When clicking on the following 3 keyboard keys simultaneously: Left-CTRL + Left-ALT + F1 Then you get to a textual terminal (CLI) where you can type commands. But there is a problem when typing English letters with Caps Lock turned on: Instead of English capital letters - you see squares, so actually you can't login to your user that way if the username/password has Capital letters. The only method which allows you to write capital English letters is to simultaneously click Left-Shift + 'a letter'. That is the only method that works well. Note that the Caps Lock key works well with the graphical terminal (pseudo / pts) that appears on Ubuntu when hitting simultaneously: Left-CTRL + Left-ALT + T --- I assumed the bug report is relevant to "shadow" package because that the "/bin/login" binary comes from that package. Package version of 'shadow' is: 1:4.2-3.1ubuntu5 ** Affects: lightdm (Ubuntu) Importance: Undecided Status: Incomplete -- Fails writing with Caps Lock https://bugs.launchpad.net/bugs/1669156 You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
