After trying to boot using a LiveUSB with Solus 1.2.1, all screens go blank (saying they are not receiving input) after some classic Linux boot lines that are seen in pretty much every distro.
This does not happen when unplugging the Graphics card and using the VGA port of the motherboard.
WORKAROUND : When you see the menu from that says "Solus 1.2", press E, and add the nomodeset option after "quiet splash". You will have a terrible resolution, but you will still be able to install Solus - once it is installed, add the nomodeset option in grub (highlight the Solus OS entry, press E, and add nomodeset at the end of the line that starts with "linux") and boot (press F10), and when you're inside Solus OS you'll be able to install the Nvidia drivers. Once that is done, you can reboot and you'll have your system fully operational!
