Searching online, it looks like this laptop has two graphics chips an
nvidia and an intel, right?

Which one of them are you using? if there's an option in the BIOS you might
want to try disabling the nvidia chip.

Note that if you're using the intel graphics card, booting with nomodeset
means the system will have to use the vesa driver, which is very basic. The
intel driver requires kernel mode setting to work IIUC.
