Can anyone suggest how I can get this resolved, or at least where to look to find the problem?
Do "dnf history | head" to find the latest update, then "dnf history info <number>" to find out all the packages that were modified. Check for anything graphics/X related. If there was a kernel update, does booting the previous kernel fix the problem?
