Hello, all. Posting because I'm at a loss for how to go about fixing this.
I took in the most recent update yesterday, which seemed pretty chunky. I let it install, it asked to restart but I said no. I powered off my computer last night. This morning, I turned it on and it's just a black screen. I usually get a Zorin + Mobo logo during a 3s period to get into the BIOS, then it moves to GRUB, then eventually auto-proceeds to the login screen. As it stands, nothing is showing.
My hardware:
CPU: AMD Ryzen 7 3700X
GPU: Sapphire 21323-01-20G Radeon RX 7900 XT 20 GB
RAM: 32GB
What I've tried/observed:
- I tried a different cord to the display. Same results. I verified with a separate device that both the cord and the display are working.
- My keyboard typically turns on during the period when I can get into the BIOS, then turns off during the move to GRUB, then turns back on. I notice my keyboard is still doing that.
- I've tried getting into BIOS. From point 2, I notice my keyboard doesn't turn off and back on, so I think I successfully get into the BIOS, but there's still no display.
- I've tried unplugging all peripherals/cords other than my mouse, keyboard, ethernet cable, and HDMI cable to the display.
- I've tried plugging in my Zorin boot stick to see if that would display to try to get at a repair utility, but I don't think it's using that boot device automatically and I can't see the BIOS to select it as the boot device.
Obviously, my best guess is something got borked with the graphics drivers, but even if that's the case I don't know what I'd do about that. I'm just using the AMD drivers that are part of the kernel.
Any thoughts on how to resolve this?
