Apparently, my late-2009 iMac screwed up, and ruined everything. I was forced to reformat and I decided to use the Ubuntu 12.04 LTS. My iMac's SuperDrive is a jerk, so I plugged in my USB on my mother's MacBook, downloaded the ISO of Ubuntu and used the dd trick.
Installing Ubuntu resulted in a black screen of nothingness, and then the monitor would die out and I have to reset. I browsed through the Ubuntu forums and luckily found out about the nomodeset
trick. Success was on my side, and I braced myself to shout victory. Unfortunately, the install hangs on this certain part with the OKs and fails.
I looked closer into it and found out that it was "Starting restore sound card(s') mixer state(s')" that failed.
What should I do?
