I am running a dual boot with Windows 10 and Ubuntu 18.04 and UEFI. I tried ubuntu live CD and it worked perfectly including recognizing monitor and setting to correct resolution. I upgraded ubuntu to 20.04. On reboot the ubuntu just gets locked at the spinning icon (let it sit for over 30 min with no progress). In debug I found entries on askubuntu that the issue could be NVIDIA drivers. I entered GRUB2 with esc, typed e and added nomodeset to the boot line. Now ubuntu boots and everything seems to work with one exception. The monitor only offers a resolution of 800x600.

In case it is useful this was my UEFI boot log before I did the nomodeset. https://paste.ubuntu.com/p/jj57bShK8Y/

In system:about it shows the llvmpipe for graphics. lspci correctly recognizes my graphics card is an NVIDIA GTX 1070.

I would appreciate any advice on how to fix the display resolution correctly. Should I have done something different than nomodeset.
Thank you in advance for any help.

OK, I fixed my issue. I originally had the NVIDIA drivers installed on ubuntu 18.04. When I moved to 20.04 they got removed. I used:

After using: How do I set 'nomodeset' after I've already installed Ubuntu?

To enter e and enabling nomodeset I was able to boot into Ubuntu but at a reduced resolution. Then I used the below entry to fix my issue.

No NVIDIA settings except Prime Profiles

$ubuntu-drivers devices (notice I think they left out the s for devices in their answer in the link) Gives a list of the drivers and the recommended driver.

Then I installed it with $ sudo apt-get install and the driver In my case it was $ sudo apt-get install nvidia-driver-440 for the NVIDIA GTX 1070.

Did not show as fixed until reboot.

Notice that I had permanently set nomodeset in GRUB but after installing the driver it was fixed so permanently setting nomodeset was not necessary. I just needed to do it once with the e command at GRUB to get into the OS and install the driver.
