Ubuntu 21.10 changes resolution, now screen unreadable

sorry for the poor quality question. Forced to type from mobile.

I am working on ubuntu for 2 week, without any problem. I have lenovo ryzen 7 laptop. Connected a displaylink usb c docking. Managed to get that to work using wayland.

Today, I worked on my laptop, disconnected from docking so on laptop screen. Some app was not scaling properly, so i changes the resolution from 3840x2160 to 1980x1020, and switched from 200% scaling to 100% scaling.

The screen looked horrible, pixelated, like the signal is completely wrong. I accidentally clicked on accept........

So with some care, i can select the previous working option (or any other, tried them all, with and without scaling). Whatever I do, the signal remains horrible.

What have I done? I don't want to completely reinstall ubuntu, i finally got everything to work... :(

Hope somebody has some tips here.

Ah... the refresh rate changed to some slightly off value. from 60 to 59.something. Putting it back to 60 solved my problem. Still it's a bit flickering on some parts of the screen, but at least I can see the contents again

How did you change that back? What should a user having the same problem do to solve it?

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.
