Bug Description

Clean install of Kubuntu 20.04, with the "install proprietary drivers" option checked. System didn't go past boot screen. Further checks suggested that there is no working graphics driver compatible with SDDM/KDE (XDM would start using VESA).

$ lspci -nn
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF116 [GeForce GTS 450 Rev. 2] [10de:1245] (rev a1)

The modalias appears in apt show nvidia-driver-440. This is incorrect, this GPU is not supported by the 440 driver. I manually switched to 390 (which is listed as supported by Nvidia) and that works. This is also seen in the support list (/usr/share/doc/nvidia-driver-440/README.txt.gz).
