    Macpro 4,1 Quad core Intel Xeon

    Hello!

    I am a long time (K)Ubuntu user who just got on of the latest MacPro from my boss. I would very much like to run (K)Ubuntu on it, but I am stucked.

    I have installed rEFIt, which detects any live cd and I am able to boot from it. However both Ubuntu and Kubuntu live cd just give me the black screen after a while (say 1 minute)

    Using bootcamp I have dedicated a partition on the hard drive to install (K)Ubuntu on it, but when I try this from the Ubuntu cd I ran into the black screen as described above.

    I have tried to look into forum posts but I have not seen this particular problem, especialy with a new Macpro

    I would be glad for any pointers!

    Some people had luck with passing the kernel argument acpi=off at boot time. Search the forum. You can try that option.

    Yeah, I saw some of those posts, and I did try to set that option with no luck...

    Thanks anyway!

    Minor update:
    * I have now tried both 32 and 64 bits versions, still with no luck.
    * I have verified that the images are burned correctly.
    * I have acpi=off _and_ nolapic

    with the last options I get the message:

    "Unable to find a medium containing a live file system"

    and I come into a BusyBox, (initramfs) shell, with limited functionality. If I only hook off for acpi=off and not the nolapic option or any other combination of options I do not get the BusyBox shell, but rather a black screen.

    Any suggestions?

    Maybe you can try a non-graphical installation with the alternate CD and work your way up from there by manually setting X.

    Ok, the alternate CD installer got me further! Thanks for the pointer!

    It seems that the actual problem was connected to some CD driver that was not detected. I was not able to get into a usable shell to issue the command modprobe ide-scsi. Probably me not knowing how Ctr+Alt+ F2 did not work. But when I choose the expert install on the alternate CD I got past the step where he complained about the drivers.

    So I'll report any progress, beyond this point later.

    Well, it didn't go too well after all.

    When I got through the first bump with the cd drive, I actually got to the point where I could repartion my harddrive. However it was too late so I thought I proceed another day.

    When I tried again, he couldn't detect my cd drive. I googled, and tried different things, like modprobe ide-scsi but no luck. I got a bit further by using an external cd rom, but after this he couldn't detect my hard drive! So something fishy is going on.

    I could not figure out why I managed to come further the previous time.

    Any suggestions are really appreciated...
