Zorin17 non-native resolution issues

General Help
1

I just updated to Z17 and my laptop display is completely freaking out if I try to set it to anything but the native resolution. I'm still pretty new to linux in general so bear with me.
Asus Zephyrus G15, running 2 external 1080 displays, laptop display is 2k which makes scaling annoying, so I'm trying to set the laptop to 1080p which worked in Z16, which causes the issue.
I tried rebooting (duh), purging all nvidia drivers and reinstalling (then rebooting), and fractional scaling, all which don't help. I also tried setting Nvidia to always use the discrete GPU instead of integrated, which also didn't work.

Do you have Secure Boot enabled in your BIOS / EFI settings?

Which driver are you using with your Nvidia Card?
You can check using Software & Updates > Additional Drivers
I recommend the 545 driver on the later kernel for the Nvidia 3070 card,.

Is the monitor cable plugged into the ports on the back of the Nvidia card or into the ports on the Motherboard?

Secure boot is disabled.

I've tried 535 and 545, no change.

It's a laptop. The display that is having issues is the laptop's own display (15 inch 2k). The external displays (one plugged into the hdmi port, one through usb-c) have no issues since I'm not trying to change their resolution. I'll try changing the resolution on those to see what happens when I get the chance.

Have you used xrandr at any point to newmode and addmode any resolutions?

5

I have not. I'm purely using the built in zorin menu for changing the resolution.

Another update. If I run Z17 using the old kernel (5.15? it's the other option under advanced setting during boot) it doesn't create the issue. It only happens with the new kernel (6.5). Is there any reason I shouldn't just run using the old kernel?

None at all. If everything is working on it, it would be your recommended kernel.
You can also set that kernel as default boot:

That way if a later kernel includes a fix to your current kernel issues, you can just revert to using it later.
