What Was My Previous OS Version?

[paul142]

A couple days ago I was prompted to upgrade my OS to 14.04 LTS so I went with it. Unfortunately it killed my machine, its slow as hell now and my laptop just cant handle it. I suppose the only fix is a fresh install which is fine. I have no idea what my previous version was, it ran really well. Is there somewhere on my machine that will tell me?

It was probably 13.10, but it doesn't matter much because only 12.04 and 14.04 are supported for a long enough period of time ATM to be viable options:

So you could try and solve the issues you're having with 14.04 or do a fresh installation of Precise. If you choose to do a fresh installation of Precise you'll likely want to use the archived 12.04.1 images from here:

The reasoning for that is due to the LTS hardware enablement policies:

I found the disk, I had 10.04. I've been limping along all these months with 14.04 on my netbook, a little sluggish but doable. I just found out about Xubuntu which is a light weight Ubuntu for older machines, I think I will put this on my laptop, although I did see some versions of Ubuntu for netbooks I guess I should check that out too. I did try Xubuntu on a old desktop yesterday and it seems to be running pretty well.
