Bug Description
[ Impact ]
After installing Nvidia driver 545 on a single (27") monitor system, Settings shows a phantom 46" monitor of the same resolution.
It looks like the phantom monitor is /dev/dri/card0 which is still controlled by simpledrm, while Nvidia uses /dev/dri/card1.
This also seems to be triggering bug 2062426 and bug 2066126.
[ Temporary Workaround ]
1. sudo rm /dev/dri/card0
2. Log in again.
[ Permanent Workaround ]
Add kernel parameter: initcall_
[ Test Plan ]
Open Settings and verify the only monitors shown are your real monitors.
[ Where problems could occur ]
Removing the simpledrm card is only safe when it's not being used. If somehow a machine wasn't using the installed Nvidia driver then there could be a risk of deleting the only working display.
