This is about installing LinuxMCE on a MacMini 2010 Model 4,1.

Install Kubuntu

LinuxMCE Logo

  • Download http://releases.ubuntu.com/kubuntu/10.04/kubuntu-10.04.3-desktop-i386.iso and burn it to DVD.
  • install Kubuntu, drop in the recently burned Kubuntu disk and boot from CD
  • follow the installer:
    • select “Login automatically” in User Information section
  • DO NOT REBOOT AFTER INSTALL! First we have to set some Grub Options to make reboot and grafics settings work. Therefor the HDD needs to be mounted and we need to change some mount points temporarily. DO following steps:
    • mount HDD Kubuntu is installed on
    • mount –bind /dev/ /media/YOUR-DISK/dev/
    • mount –bind /proc/ /media/YOUR-DISK/proc/
    • mount –bind /sys/ /media/YOUR-DISK/sys/
    • chroot /media/YOUR-DISK/
  • edit: nano -w /etc/default/grub
  • change GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash” to GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash nomodeset reboot=pci”, save and exit
    • nomodeset fixes black screen after boot
    • reboot=pci enables reboot, if not set it won't reboot
  • update-grub to apply the new settings to grub
  • reboot
