18.04 Live session not displaying. "Mode Unsupported" message on any screen

  • 772

I've been trying to boot into a live session so I can use gparted to upgrade to a larger SSD, but I've only been able to get into it once. I let it suspend by accident that one time and I wasn't able to get back into it. After rebooting manually, my display ports weren't working, so I switched both inputs to HDMI. Now every time I try to get into a live session, either of my monitors display the message "Mode Unsupported". I can only get as far as "Try ubuntu before installing" after which the screens go black, or just the one screen since I tried it with just one of two plugged in.

I also have to boot into the USB through UEFI which might cause issues? Setting the boot sequence to USB first in Legacy BIOS doesn't work.

Did something break in the grub when I rebooted that one time? I've tried a number of times, and after each failed attempt my monitors (dual screen) revert to "stock" settings, but regain my custom settings once logged in.

Any help would be greatly appreciated.
