Обычные драйверы Ubuntu не распознают nvidia-driver- 450

• Ubuntu18.04
• CUDA 10.0
• Ядро 5.3.0-53-generic

Я обновил библиотеку CUDA с версии 10.2 до 11.0, следуя инструкции NVIDIA здесь .

Графический процессор правильно распознается как:

$ lspci  | grep -i "nvidia"
01:00.0 VGA compatible controller: NVIDIA Corporation Device 1ed0 (rev a1)
01:00.1 Audio device: NVIDIA Corporation Device 10f8 (rev a1)
01:00.2 USB controller: NVIDIA Corporation Device 1ad8 (rev a1)
01:00.3 Serial bus controller [0c80]: NVIDIA Corporation Device 1ad9 (rev a1)

Тем не менее, ubuntu-drivers-common не распознает новый nvidia-driver-450:

$ ubuntu-drivers devices
== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==
modalias : pci:v000010DEd00001ED0sv00001028sd000008C4bc03sc00i00
vendor   : NVIDIA Corporation
manual_install: True
driver   : nvidia-driver-435 - distro non-free
driver   : nvidia-driver-440 - third-party free recommended
driver   : nvidia-driver-418 - third-party free
driver   : nvidia-driver-430 - third-party free
driver   : xserver-xorg-video-nouveau - distro free builtin

Интересно, почему это так? У вас есть идеи?
Спасибо.
