When starting a 64bit kernel on the imac i get a console and i can start X. When starting a 32bit kernel on the imac i don't get a console and i cannot start X. I have been troubleshooting this for a while now and i thought it was an error in the graphics driver, but that has been ruled out with the help of the upstream developers. I have then removed plymouth from the 32bit initrd (just removed the scripts) and my console started to work. So then i enabled plymouth:debug on the kernel cmd on both the 64bit kernel and the 32bit and i was a little surprised to see that the 64bit initrdl tried to load the i915 driver and failed and the 32bit driver loaded the radeon driver and succeeded but there my console gets disabled somehow. Attached the debug logs for 64bit and 32bit plymouth debug. This system has a hybrid graphics setup. It contains a intel graphics card and a discrete radeon GPU (where the monitor is connected to). - --- + --- ApportVersion: 2.8-0ubuntu2 Architecture: amd64 DefaultPlymouth: /lib/plymouth/themes/ubuntu-logo/ubuntu-logo.plymouth DistroRelease: Ubuntu 13.04 MachineType: Apple Inc. iMac12,1 MarkForUpload: True Package: plymouth 0.8.8-0ubuntu5 PackageArchitecture: amd64 ProcCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.8.0-0-generic root=/dev/disk/by-uuid/1cf43b8b-2366-4c78-b994-e6f08ee6ea42 ro keyboard=us ProcEnviron: - TERM=linux - PATH=(custom, no user) - SHELL=/bin/bash + TERM=linux + PATH=(custom, no user) + SHELL=/bin/bash ProcFB: - 0 inteldrmfb - 1 radeondrmfb + 0 inteldrmfb + 1 radeondrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.8.0-0-generic root=/dev/disk/by-uuid/1cf43b8b-2366-4c78-b994-e6f08ee6ea42 ro keyboard=us ProcVersionSignature: Ubuntu 3.8.0-0.4-generic 3.8.0-rc3 Tags: raring TextPlymouth: Error: command ['readlink', '/etc/alternatives/text.plymouth'] failed with exit code 1: Uname: Linux 3.8.0-0-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: - + dmi.bios.date: 01/24/12 dmi.bios.vendor: Apple Inc. dmi.bios.version: IM121.88Z.0047.B1F.1201241648 dmi.board.name: Mac-942B5BF58194151B dmi.board.vendor: Apple Inc. dmi.chassis.type: 13 dmi.chassis.vendor: Apple Inc. dmi.chassis.version: Mac-942B5BF58194151B dmi.modalias: dmi:bvnAppleInc.:bvrIM121.88Z.0047.B1F.1201241648:bd01/24/12:svnAppleInc.:pniMac12,1:pvr1.0:rvnAppleInc.:rnMac-942B5BF58194151B:rvr:cvnAppleInc.:ct13:cvrMac-942B5BF58194151B: dmi.product.name: iMac12,1 dmi.product.version: 1.0 dmi.sys.vendor: Apple Inc.
