Now copy the "efi" - folder from the rEFIt archive () to the root of the partition. Make sure to name your partition, for example I named it just "EFI". Maybe you kept your "EFI System Partition" and that could probably also work. I think a 20 MiB size should be enough but a little more dont hurt. Latest SystemRescueCD has the capability to create this for you in GParted or you can just do it in MacOSX or through the MacOSX install CD and Diskutil. You need a partition of HFS+ type (maybe FAT32 will also work). Verify that the setting stuck with this command: $ gksudo leafpad /etc/init.d/ondemandChange the line that reads:Įcho -n performance > $CPUFREQand restart your computer. $ sudo apt-get install cpufrequtils sysfsutils Lastly you should set CPU Frequency Scaling to "performance" setting: $ sudo dpkg-reconfigure keyboard-configurationChoose your keyboard modell (mine was "MacBook/MacBook Pro (Intl)") and follow the instructions until you get to which key to use for AltGr in which case you choose "Alt, left". This is how you fix the "alt" - key not working on your non-US Mac ("third level" or AltGr - so you can type the at-sign for example) in Xfce / Xubuntu: RTIRQ_NAME_LIST="rtc ohci1394 snd usb i8042" and save it. RTIRQ_NAME_LIST="rtc snd usb i8042"into this: $ sudo leafpad /etc/default/rtirqChange the line that says If you are using a Firewire soundboard like me you need to set the IRQ-priorities that you can read about here: () $ sudo apt-get install linux-lowlatencyMake sure you check whch kernel you are currently using: $ sudo apt-get install linux-realtimeI guess this is an alternative: $ sudo add-apt-repository ppa:abogani/realtime $ update-manager -d I installed the realtime kernel from here (): Therefore I needed to upgrade to 12.04 beta (everything with $ at the start of the line is a command you run in the Terminal): You need a real time kernel if you are planning on recording music. Read the instructions carefully as it says again and again that you should modify /etc/udev/rules.d/les and /etc/security/nf while it also says that you shouldn't (which in this case is the correct thing to do: don't modify them!).Īt the time of this writing there doesnt seem to be any realtime kernel available for Ubuntu 11.10. Since you are running Xubuntu you don't have gedit but should instead use leafpad. Once in Xubuntu, download and install Ubuntu Studio as per these instructions (). Choose rEFIt and the partition tool and let it do its thing. Hold down alt while starting the computer, eject the Xubuntu disc and insert the rEFIt cd, shutdown your mac (by holding the power button pressed for a few sec) and start it up again holding alt. If it doesnt boot, if you are having multiple OS's installed or if you have rEFIt installed you need to update your MBR-table via rEFIt's Partitioning tool. Restart the computer and you should now be running Xubuntu. Install Xubuntu on your harddisk (probably prefereably the whole drive) and let it install GRUB if it's not already installed and you are planning on using just one OS. Put the CD in your drive, restart the computer and hold down the "alt" ("option" in mac-lingo) key. I used the "Alternate CD" 32-bit version so I'm not sure if the "Desktop CD" works. A second computer in case you need to download another distro or something. Atleast one backup distro that you are sure boots on your Mac and includes Parted or GParted in case you screw up (I am using SystemRescueCD) () Ubuntu Studio don't have this version which is the reason for this thread. Regular Ubuntu have a specific Mac version sans UEFI which won't confuse your mac and let it boot in BIOS-emulation mode. The Ubuntu Studio install DVD supports BIOS and UEFI but, probably because of a bug or something in Mac's EFI implementation, Mac's can't boot it. Mac's don't have BIOS nor do they have UEFI (the new industry standard) but they instead use EFI and a BIOS-emulation mode. Be aware that tools like Parted/GParted might destroy your partition table leaving you with a unbootable system.Ģ. rEFIt () will help you with creating a hybrid table aswell as Apple's own BootCamp. If you will only run one OS on your computer then this is not a problem. They use GPT instead of MBR and in order to boot OS's other than MacOSX you need to setup a GPT/MBR hybrid partitioning table. Mac's don't use the same partitioning table as everyone else. Installing Linux on a Macintosh is tricky because of two reasons:ġ. EDIT: THIS IS HOW YOU GET LATEST UBUNTU STUDIO WORKING ON A MAC / MACBOOK!
