Stephen said this happened "when [he] logged in." Stephen, assuming you actually logged in before the issue occurred, did you log in to a login/display manager such as LightDM or did you log in to a console/CLI prompt and subsequently run startx, whereupon the issue occurred? If the former, either X or Wayland is running at the point of "login screen", isn't it? At some "standard" (high-ish, working) resolution? "[...] systemd [...] starts all the important system processes and then starts X11 [...] which in turn starts a login manager [eg.] LightDM [...] The login manager starts a session manager [...] which starts a window manager and usually a menu bar, a desktop [...]" https://dev.to/jfhbrook/what-s-a-desktop-session-manager-and-why-do-i-want-one-agl Doesn't this suggest a display configuration problem rather than a hardware issue? Thanks Gareth
