getting ready to use PI on Linux
« on: 2017 April 17 07:59:50 »
Hi all,
I bought a new computer, that came with Windows 10, and am going to REPLACE W10 with Ubuntu. I've already screwed that up twice, being totally naive about Linux, but am learning from each failure. I'm hoping that the next try is the success! Anyway, I have 256GB of ssd and a 1TB hdd. I guess I have two questions, at this point. First, what is the best way to partition these two disks for PI? (Image processing is to be the dedicated purpose of this machine.) That is, where are the various things like '/', /swap', and '/home' and whatever else I need best assigned best located (ssd, hdd, both)? (To be honest, I don't really know what the 'x' things are even called, so be gentle!)
My second question is where to install PI, I tried to put it on the hdd (with the system on the ssd for my latest installation attempt) and while it did not complain, it also did not work. At that point, the hdd was just as Windows left it. I had located the script and the PI icon, and neither did a thing when clicked/executed. I suspect the script did not find the things it needed at the locations where they were supposed to be.

Any help you can provide or links you can point to are greatly appreciated.

Alex

Hi!

Welcome to the Linux world...:)

My partition on my desktop is something like
root partition, where the system is installed: /   about 60 or 80 GB
home partition, the rest of the same drive (in your case the SSD): /home
then I have, as you, a HDD for images. I have this in /home/magnus/astro
I'd suggest that in the installation, when you come to partitioning, you choose "Something else" and partition according to a plan, possibly something along the lines I suggest.

Maybe you need a swap partition as well, and maybe an EFI partition for booting I have a small EFI partition (~1 GB) first, then the root (/), then a swap, then the home (/home) on my first drive.

When installing PI on ubuntu, you'll probably run into a dependecy problem. See here:

It will work, you just need to find and install a proper libgstreamer package. I can't recall now where I found mine 2 weeks ago, but someone else probably knows if that thread doesn't solve it.

Magnus,
  Thanks, that's a big help. Sorry I've not responded sooner. Was off having doctors poke holes in me. Oh the good old days of leaches!
