Parent was excited about his contribution. Just because you want insight into "the process" doesn't mean parent has to deliver to you.

I don't think he should feel obligated to deliver. But, I think comments should generally add to the conversation. If they don't, I tend to down vote them.

Boot from the disk and tell it to upgrade your 11.10 installation, saving your /home folder and so on. I did exactly this on two workstations and found it works quite well ..

Is there any reason why you choose to boot from a disk? Normally you can upgrade from within your own installation without problems.

To me, it's good to have a disk with the last version of ubuntu in case I need it. So if I download the disk and boot from it, I'll only download it once, versus downloading the iso + downloading the upgrade.

Also, the upgrade to a new version famously have many problems. I just tried it and it crashed in the middle :S

I'm one of those weird folk who run three monitors, and even though 12.04 promised better 2+ monitor support through Unity 2D, I still find it lacking. Perhaps it's the way I have it configured, but I use two nvidia cards with xinerama, which means I'm forced to use Unity 2D (no compositing support). Unity 2D just isn't as stable or usable. I really, really hope they put more effort to fixing this in 12.10.

I fought with this in the past. In the end I unhappily switched to back to windows running linux VMs after years of using linux as my primary desktop OS, and it was purely because of this failure.

Don't expect multiple graphics cards to work well under linux, at all. I tried this for quite awhile and there are a number of bugs. The one that bit me the most was that when a mouse cursor cross a screen boundary that switches GPUs and there is an animated cursor running, the mouse gets all messed up with the clicks being sent to the wrong screen, click on screen 1 and the event is sent to screen 2. I also had constant issues across many version of X with the Xorg process pegging a CPU core and making the system unusable.

Xinerama is all but deprecated it seems, RandR was supposed to replace the multiple graphics card support and allow multi-gpu composting but the project hasn't gotten around to it despite the fact that they've been talking about multi-gpu handling for more than 3 years.

My "workaround" for a long time was using a Matrox tripleHead2Go to let me get 4 monitors onto a single nvidia card. But, this approach has inherent limitations, all displays have to be oriented the same way and have to be side by side, what I wanted was one screen in landscape, 2 in portrait on the sides and a couple extra above.

At this point the best bet is hoping that wayland handles multi-gpus far better than X does.

Have you tried Nvidia TwinView? This should let you operate the monitors with some 3D support.

TwinView also doesn't support rotating one of the screens, which is a show stoppper for me.

Actually, it "does", but it requires some magical incantations, and you end up with a virtual desktop with lots of off-screen pixels, and your desktop/window manager has problems figuring that out. That's why I started using the Nouveau drivers; it fully supports Xrandr, which means you can use the desktop manager's built-in screen rotation abilities.

Is there a reason that Canonical doesn't make upgrading via torrent more front-and-center? It seems like on huge release days like today they'd want the swarm to lend itself a hand.

I guess probably to simplify things, the less links to "get" the product the better, especially if they are going after less savvy users who may also believe that bittorrent is illegal or shady in some way.

They could just build it into do-release-upgrade and use bittorrent behind the scenes, then nobody would really be the wiser.

If replying to a comment with "Upvoted" is unproductive, what's more productive about saying "Downvoted"?

Perhaps you could have just left the comment without the downvote? That would likely achieve the same results.

I just spent over an hour last night upgrading one of my laptops to 11.10 because 12.04 was still beta. I guess I should have just waited one more day.

If you were coming from 11.04, you'd have to upgrade to 11.10 anyway, since you can only upgrade from one release directly to the next one, or one LTS to the next. That's why I suspect you were on 11.04 and not 10.04 (it's not possible to upgrade directly from 10.04 or 10.10 to 11.10).

The alternative would have been a clean reinstall.

So basically you did the right thing.
