You have been subscribed to a public bug: With a 27in 5k ( new as of two weeks ago) I'm unable to boot the kernel without parameter "acpi=off:", it also needs "nomodeset" into order to get a working system.
The applies to both the live installer and a system installed on disk. With out the parameters I just get a blank screen. It gives a blank screen event if the "quiet" is removed from the kernel parameters. The system has a 250G SSD. I'm using the Kubutu live installer for Wily off a USB stick. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: bot-comment kernel-bug -- Ubuntu not booting on iMac 5K with ACPI enabled https://bugs.launchpad.net/bugs/1525615 You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
