It sounds like you have zoom enabled. Unfortunately other bugs make it difficult to disable.
On the login screen: 1. Click on the person icon near the top-right (the accessibility menu). 2. Select the second option in the menu that appears (but may appear partially missing). That is the "Zoom" option. ** Package changed: xorg (Ubuntu) => gnome-shell (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1800809 Title: login screen is huge Status in gnome-shell package in Ubuntu: Invalid Bug description: After login, screen resolution goes back to normal (1920X1080). But login screen is huge compare to the actual monitor. Because the login screen is too big to fit inside the display, I see only the upper left portion of the login screen (its like someone put a magnifying glass on the login screen and I can see only part of it). I have to move the mouse and then the user list in the login screen moves to the right and I can select my user.
