I have been working on this problem now for a solid day and would really appreciate some help!

I am attempting to dual-boot Ubuntu 20.04 on an existing Windows installation. The Ubuntu install works on nouveau drivers, but upon installing nvidia-drivers-460 the boot-up hangs on the motherboard manufacturer screen. All hardware works on the Windows install so it's certainly a software problem.

Hardware information:

  • Mobo: ASUS PRIME Z590-V
  • -> Checked that BIOS is up to date
  • SSD: 1TB WD Blue SN550 Series PCIe NVMe
  • CPU: Intel i9-10900K 10/20
  • GPU: ZOTAC GAMING GeForce RTX 3090 Trinity

What I've done:

  • From Windows, shrunk the NVMe FAT partition and set aside 300 GB for Ubuntu,
  • Disabled secure boot in BIOS
  • Installed Ubuntu 20.04.2 onto freed partition from a USB flash drive,
  • -> Chose option to not install graphics drivers at this point,
  • Ubuntu successfully boots using nouveau drivers,
  • Install updates etc. via Ethernet connection,
  • Reboot, no problems. Now install nvidia-drivers-460 (recommended). Tried various approaches such as ubuntu-drivers, reinstalling the OS a few times, etc.

The problem:

  • Grub boots successfully. But, Ubuntu cannot boot (hangs at ASUS screen) and recovery mode fails at "Reached target local encrypted volumes".
  • Because I cannot even reach the recovery screen, at this point I need to reinstall the OS from the flash drive.

Picture of where recovery mode hangs attached. Any help is seriously appreciated!

When there is GPU drivers in play, there is a golden boot settings : nomodeset

This will basically disable any hardware acceleration before the X server starts (and sometimes will disable all hardware acceleration see this for more info)

Here are the steps :

  • With the selector on your main GRUB entry press e to enter the editor
  • Find the entry that starts with linux
  • Delete quiet splash (or anything you have at the end of the line, but not touching any word that starts with a $) from the line (don't worry the change is only going to last one boot) replacing it with nomodeset (the line should look like this
linux   /boot/vmlinuz-5.9.12-050912-generic root=UUID=<REDACTED> ro nomodeset $vt_handoff
  • Boot using F10 and wait to be spawned to the DE (if you don't no worry, stike Ctrl-Alt-F2 to enter the tty)

Then try this NOTE : Replace gedit with nano, especially if you're running Wayland (Wayland can be an horror with proprietary drivers, and GUI apps that require root privileges)

If it doesn't work make a full reinstall of the drivers (see here (omit the secure boot part))
