A few weeks back I built a new desktop PC and installed Kubuntu 20.04. Everything booted fine and I was able to install the Nvidia 460 driver to support the RTX 3070 card that I had installed. Fast forward to this morning and when I boot the desktop im greeted with a blinking cursor instead of the Kubuntu login UI.
I ALT+F2 to get to a TTY and do a few checked, uninstall the driver, reinstall and everything I can think of to try and get the desktop to boot correctly.
When i check lshw I did notice some odd things. For example:
description: VGA compatible controller
product: NVIDIA Corporation
vendor: NVIDIA Corporation
physical id: 0
bus info: pci@0000:2d:00.0
width: 64 bits
capabilities: pm msi pciexpress vga_controller bus_master cap_list
The display is UNCLAIMED, the Product is simply set to NVidia Corp and not the actual product name and the configuration property does not refer to the driver version being used.
I keep Kubuntu up to date and my only guess in that an update last night has caused this issue. Im not technical enough to dig really deep into this but im happy to work with anyone who might be willing to lend a hand.
As far as the hardware is concerned, this is a dual boot system and the Windows 10 partition work fine with the 3070 and Nvidia drivers so im leaning more towards a software issue.
