When I use the Nouveau display driver with a NVIDIA Quadro P4000, my system crashes when I try to view an animation with the Videos official movie player. (The animations can be viewed with VLC media player.) If I use one of NVIDIA's proprietary drivers (nvidia-driver-435, nvidia-driver-390, or nvidia-driver-430), the Videos movie player works but the option to decrypt my hard drives on startup is not displayed. I can, however, input the password blindly to decrypt my hard drives and get the login prompt. I am enabling the NVIDIA drivers using the Additional Drivers tab in Software & Updates in Ubuntu 18.04.4. I would like to get fixes for both types of drivers. BIOS 2.0b is current for Rev. 2.00 motherboard with 32MB SPI flash ROM.
