I know this question has been asked before but the suggested solutions I found on the web did not work for me. I am trying to boot into my ubuntu partition and it is getting stuck on the purple screen before the logo shows up.

I believe I might have updated some nvidia drivers before this problem began (software updater gave me a big list and I just pressed install).

Editing grub and changing quiet splash to noapic noacpi nosplash irqpoll the boot got stuck on [OK] started Daemon for power management.

Booting from an older kernel (5.4.0-72-generic) let me log in but the resolution was locked to 1024x768 and the graphics were generally really bad so I assume the graphics card was not being used.

Does anyone have any suggestions on what other steps I can take to debug/fix this issue?

Thank you!

Remove all the nvidia packages and reboot.

sudo apt update  
sudo apt-get remove '^nvidia'  
sudo apt autoremove  
sudo reboot

After rebooting Ubuntu will be using the built-in Nouveau open source graphics driver instead of the proprietary Nvidia graphics drivers.

If this doesn't work, the other possibility is that the boot problem is caused by a kernel update that is answered in this answer.
