Ubuntu – Ubuntu 13.04 on UEFI system hangs at black screen


OK, so it seems this question has been asked before but not successfully answered. I have a Windows 8 Toshiba P75-A7200, and I've disabled Secure Boot, Fast Boot, and Fast Startup. Still, when I try to boot a Ubuntu 13.04 USB installer, I get to the GRUB screen and when I select "Try Ubuntu Before Installing," it hangs on a black screen. I had also tried booting in Legacy Mode, and it was the same.

The answers that I've seen haven't helped me, since they seem to assume I can access the Ubuntu terminal?

I've read this:
My computer boots to a black screen, what options do I have to fix it?
But disabling secure boot and enabling BIOS Legacy Mode didn't help. My computer doesn't have an UEFI/BIOS option; only UEFI or BIOS.

Same with this:
Installing Ubuntu Alongside a Pre-Installed Windows with UEFI
It suggests the same things, which don't work.

They both assume that I can get to the Ubuntu installer.
I've also tried to install Linux Mint, and it was still unresponsive. I used 64bit for both, of course.

So Ubuntu is supposed to be able to work with UEFI and secure boot. What's going wrong?

PS It is a black screen, not a purple screen, so I don't think the problem is my video drivers, because I've had that happen on another computer. I know the problem is the UEFI, since I've installed Linux on three other Windows 7 computers just fine.

EDIT: dd just try to switch to nomodeset, and that took me to the ubuntu command line. I tried startx which resulted in an error, so I am lost on how to proceed?

Best Answer

Try these instead of nomodeset or in addition to nomodeset: acpi_osi=Linux acpi_backlight=vendor

Since you have a very new system, you may really need all the fixes that will be in 13.10 as both Kernel & Intel drivers have changes. But we only suggest 13.10 for those users who realize that is it not final, may crash and those bugs need to be reported so additionally fixes can be made. Or you are a tester not a user.
