Description of problem: When booting an EFI Mac with nomodeset, safe graphics mode isn't available, only text boot occurs. Seems to be a regression.
Version-Release number of selected component (if applicable):
Fedora 20 beta (final)
Always, on two EFI Macs. One has nvidia graphics, the other hand dual intel/radeon graphics.
Steps to Reproduce:
Boot with nomodeset param.
tty1 hangs at gnome-shell, no graphics. I can switch to tty2 and get a login prompt.
To see GDM, login, etc.
Worked with xorg-x11-server-1.14.2-3.fc19.uefi1.src.rpm per

Macbook Pro 4,1 has UGA graphics
NVIDIA Corporation G84M [GeForce 8600M GT] [10de:0407] (rev a1) (prog-if 00 [VGA controller])
Macbook Pro 8,2 has GOP graphics
Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0126] (rev 09) (prog-if 00 [VGA controller])
Advanced Micro Devices, Inc. [AMD/ATI] Whistler [Radeon HD 6630M/6650M/6750M/7670M/7690M] [1002:6741] (prog-if 00 [VGA controller])
Proposed as a Blocker for 20-final by Fedora user chrismurphy using the blocker tracking app because:
Alpha Release Criterion: "The boot menu for all supported installer and live images should include an entry which causes both installation and the installed system to use a generic, highly compatible video driver (such as 'vesa'). This mechanism should work correctly, launching the installer or
desktop and attempting to use the generic driver."
Could be a Mac EFI edge case, but considering it was working with an earlier version, I suspect other UEFI hardware will be affected.

This does not affect only Macs, see bug 1030454. Ajax should have a fix soon:

This build should fix the problem:
xorg-x11-server-Xorg-1.14.4-4.fc20.x86_64 fixes the problem on Macbook Pro 4,1.
Also fixes the problem on Macbook Pro 8,2. So at least one case each of UGA and GOP graphics fixed.
xorg-x11-server-1.14.4-4.fc20 has been submitted as an update for Fedora 20.
xorg-x11-server-1.14.4-4.fc20 has been pushed to the Fedora 20 stable repository. If problems still persist, please make note of it in this bug report.
