My OpenSUSE Tumbleweed system is currently updated to the latest version, but when I enter the desktop, I found that the resolution has become very low and blurry, and I cannot adjust to other resolutions. My monitor has a 2K resolution, and the graphics card is RTX3060. I didn’t encounter this problem before. Can someone tell me what I should do? Thank you very much!
@lihetongxue Hi and welcome to the Forum 
Can you please post the output from inxi -GSaz
No problem. I’ll provide it later.
It’s worth adding that this problem happens should have something to do with my cat, it always jumps on my mainframe many times when I’m not at home, causing the mainframe’s on button to be abnormally turned off and on many times, and when I noticed it, the opensuse startup item reset and went straight to windows,I changed it back, but this resolution loss problem happens when I go to opensesu.

@lihetongxue This is not a hybrid system with the iGPU disabled?
So no nvidia driver loaded indicated by driver: N/A and using modesetting.
There is a newer driver out 570.124.04 which can upgrade to with zypper dup
@malcolmlewis I upgraded to that driver using zypper dup, then rebooted and got into the system and the resolution was only 1080p, I rebooted again and got into the system and went back to a much lower resolution and it was just as blurry as before.
Does this apply to your situation?

Perhaps examine
sudo journalctl -b |grep nvidia
That was the reason, I turned off secure startup and everything worked fine, that’s cool, thank you very much!
