I have a Macmini4,1 (most recent variant) with a Mini DisplayPort connected to a DVI monitor, and HDMI connected directly to a projector. Both monitors are on but black when booting of the ‘Natty Narwhal’ Live CD.
I hold the Option key to get into the EFI boot selector and choose the CD’s EFI boot. Grub loads, and I choose Try Ubuntu from the grub menu. From there on the screen is black.
How can I get Ubuntu to detect my available monitors? Anyone got the same experience?
