Title:
  1002:9488 [iMac11,2] 12.10 quantal boots to black screen on iMac

Status in Linux:
  Confirmed
Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Running 12.10, updated today, on iMac 11,2 (mid 2010) with AMD Radeon 4670.
  Using kernel radeon driver (lsmod shows it running). Normal boot results in black screen. Ctl-Alt-Del reboots; indicating that system did boot. This appears to be a regression in the kernel, similar to bug 597070 (ubuntu 11.04 - used fglrx to get video to work) and to bug 863969 (ubuntu 11.10 - where an upgrade to the 3.2 kernel seemed to improve video detection). Suspend and resume does not work either, not turning off the system, only the video, and resuming to a black screen. I think the problem is in KMS, because the black screen happens even if I boot into text mode and using nomodeset fixes it. Hence filing this against xorg but expect it to go to kernel developers.

  WORKAROUND: Use kernel parameter nomodeset.
