Monitor resolution is suddenly low, with no option to change it

I've been using ubuntu (dual-boot) for a few weeks now and today the resolution went to 1024x768, with no way to change it.

I first tried the fix where you update the grub file to the resolution of the monitor, in my case 2640x1440. After updating grub and restarting, nothing changed.

Then I went to the 'software and updates' app and tried switching from the nouveau driver to the (proprietary,tested) Nvidia open kernel 520 driver. Then I restarted and nothing changed.

I'm on Ubuntu 22.04.1 LTS, with a 3060ti GPU

Here's some of the commands I ran, to give you more info:

:~$ lsb_release -a

I'm not very familiar with linux, so I'm not sure if I should try and follow the answer from this post, where the solution was to purge the driver,reinstall, and (i think) force the driver to work with the kernel?:

nvidia driver not detected. Screen is on low resolution

918

0 + 4

nvidia

drivers

display-resolution

No, that answer is likely not applicable. Just disable Secure Boot in UEFI and try again.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
