I have a new PC with intel i7 10700 CPU and an ASUS B560M Pro4 MOBO. I've installed Ubuntu 20.04 using Safe Graphics mode but whenever I boot, it goes to a black screen (monitor says no signal). I've tried reinstalling, downgrading my intel microcode version, and adding the dis_ucode_ldr flag on boot, but nothing has helped. I'm at a loss as to what to do, and am unable to use the new PC at all.
EDIT: Adding nomodeset appears to boot, but only in low resolution, which I can't change. I looked at Additional Drivers, and it says "No additional drivers available." How do I increase the resolution? Thanks!
