Comment on How to Install Ubuntu 14.04+ on MacPro 1,1 (EFI boot mode) by admin

In reply to Martin.

Martin, re: HDD detection – never had the issue. My setup could also be a bit different from yours, as I have my system drive (an M2 SSD in a PCI adapter) connected to one of the onboard SATA (not one of the 4 regular drive slots). Also, I tried this long time ago on Ubuntu 14.04, if you are trying some other Ubuntu version, the experience could be different. Re: server version to install – just install server, then “sudo apt install ubuntu-desktop”

In reply to Trevor Green. Thanks. Headless is the way to go, unless you require controls and display at the point of use, as Chromium on PI zero pretty sluggish. If you can put a double box into wall, all the better! (I could not)

Very cool. I’m going to try something like this. Might go headless though and see about integrating this straight in to Home Assistant as I have 6 different pads and 6 controllers at present.

Perhaps a 2 gang box so there’s enough room for the relay/ADC/Pi zero/GFCI plug, just blind off the one Decora. Perhaps I can mate a small display to a Decora hole (even 3D print something) so there can be a local temp indicator.

Thoughts on that integration?

In reply to Chris. Try disabling DVR-ROM (disconnect it) - this helped me on other platforms.

In reply to Chris. Update: I added nomodeset to the grub.cfg and I can see more of the kernel output. It tries to read from /dev/sr0, but fails after a large number of attempts. I assume this is the DVD-ROM? Anyway it eventually gives up trying to read from /dev/sr0 after many tries and says it cannot locate a live file system. It then offers to boot from the network. I checked that my PARTUUID was correct for sdb1 (the partition where the Ubuntu live filesystem resides), and it was not. So I fixed PARTUUID after checking it with blkid on another machine, and set it correctly. But it still ends up in the same state, trying to unsuccessfully read from /dev/sr0, then failing to boot the live file system.

I got a little bit further by adding noefi parameter back to grub.cfg. Now I can see kernel messages after the kernel starts to load. It stops at the following line:

fb0: switching to radeondrmfb from EFI VGA

It has been stuck here more than 10 minutes…

I am trying this on my Mac Pro 1,1 with dual 3GHz Xeons, 9GB RAM and Radeon X1900 XT video card, using Ubuntu 20.04.1 on an 8GB USB, but so far I have not been able to boot into a live environment, just a black screen.

I have tried both disk creator in Ubuntu 20.04.1 and the manual method, both seem to end up with the same black screen. I followed the instructions with a few adjustments:

1. I removed the noefi parameter from grub.conf, as per instructions that it’s no longer needed. I have not tried it with the parameter, yet.
2. I used the correct name for initrd in my grub.conf

My Mac has no issues seeing and booting from the EFI usb. I get the grub menu, choose Linux and press enter. Then, I get a black screen with non-flashing cursor for a minute or so, then the screen goes completely blank… then… absolutely nothing seems to be happening. I have left it this way for at least 5 minutes, but nothing happens.

Any ideas? My Mac is fully up-to-date running 10.7.5 Lion, the latest supported OS X version. My plan if I can get a live environment to boot is to then shut it down and swap the current HDD for a spare 256GB SSD that I have lying around, then install pure Ubuntu on the SSD.

There is a Ubuntu distro 20.04 / 20.10 on Live USB with NVIDIA support that I run on Mac Pro 4,1 and 5,1 with NVIDIA GTX1080Ti. Didn’t try it on Mac Pro 1,1 but it might work if 64-bit instructions are supported. The name of the distro is called LivelyLinux. You can find it using Google or YouTube. It is not free but inexpensive and gets installed directly to the USB drive without a hassle.

I followed these instructions for Ubuntu 18.04.5 and encountered the grub error – the installer couldn’t install grub to the target disk.

I rebooted and dropped to the grub command line. It sees two devices: hd0 with partitions named apple1, apple2 and msdos2, and hd1 with partitions gpt1 and gpt2.

hd1 is the internal disk, and gpt1/ gpt2are presumably /boot and /. Unfortunately, grub returned ‘unknown file system’ when I tried to list the partition files.

Really have no idea what to do next. I’ve tried both methods for creating a USB stick. The manual method simply generated an error that it couldn’t find a live file system and dropped to an initramfs shell.
