My desktop PC has an NVIDIA GeForce GTX 550 Ti. Just installed Focal selecting
the option to install 3rd-party drivers during setup process, and after the
first boot screen resolution is 800x600.
I verified the detected version of NVIDIA driver and I realized it was 440,
although correct version is 390. Finally I manually installed proper version
(390) and now the graphics are working OK.
This is the output for the command "$ lspci -nn":
01:00.0 VGA compatible controller: NVIDIA Corporation GF116 [GeForce GTX 550
Ti] (rev a1)
01:00.1 Audio device: NVIDIA Corporation GF116 High Definition Audio Controller
(rev a1)
This is the output for the command "# ubuntu-drivers devices":
== /sys/devices/pci0000:00/0000:00:02.0/0000:01:00.0 ==
modalias : pci:v000010DEd00001244sv00001043sd000083BEbc03sc00i00
vendor : NVIDIA Corporation
model : GF116 [GeForce GTX 550 Ti]
driver : nvidia-driver-435 - distro non-free
driver : nvidia-driver-390 - distro non-free
driver : nvidia-driver-440 - distro non-free recommended
driver : nvidia-340 - distro non-free
driver : xserver-xorg-video-nouveau - distro free builtin
The version 440 is recommended, but it's not correct for this model (390
should be recommended instead)
The issue was not present in previous versions (in both 19.10 and 18.04 driver
390 was recommended correctly)
