I am attempting to install Ubuntu 12.04.4 LTS on my MBP 5,3, however I have run into some issues regarding the process. Attempting to fix the second is made more difficult by my fix for the first, so I need some help finding a workaround.
Issue #1: No video when booting from LiveUSB (or LiveCD).
So I added "nomodeset" to the boot parameters. Now, when selecting "Install Ubuntu", it boots just fine. However, when selecting "Try Ubuntu", it just boots to a command line (which I have gathered is normal for nomodeset).
(For reference, I attempted to use the "outb" commands, but grub didn't understand them.)
Issue #2: Ubuntu hangs on "Preparing to install Ubuntu" page. Documented: Ubuntu 12.10 Installation Hangs at 'Preparing to Install Ubuntu'
I cannot attempt any of the fixes for this because pressing Ctrl-Alt-F1 to bring up a terminal makes the installer disappear and brings up just a command line (as if I booted into "Try Ubuntu").
I do not know where to go from here. Any suggestions?
