Ubuntu... downgrade? (64-bit - 32-bit)
Hey, all. I've got a big ol' RAID box that I use to store... well, pretty much everything. Threw 64-bit Ubuntu on it, 'cause, well, why not? I now know why not. I'm afraid I've fallen into the portable device rage, e.g., my Droid-X. Nifty thing, it is -- even set it up with VPN, SIP through my job, and all sorts of other fun stuff. Now I'd like to play video from my server on the phone. Unfortunately, its media player is pretty useless -- far better to generate video from the server, and stream it, apparently. But! 64-bit CODECs are also kinda lousy. And it's not like I have a oodles of RAM -- 2 GB -- so dropping to a 32-bit system won't really harm anything. But Googling that doesn't really help much. Any suggestions? What I'd *love* to do is an apt-get update;apt-get dist-upgrade, and be done with it. Somehow, though, I'm thinking it won't be that simple. I'd really like to avoid a full re-install -- a lot of configuration has gone into this silly thing, and, while I could backup /etc and pray that was enough, I'd prefer not to find out the hard way.

Re: Ubuntu... downgrade? (64-bit - 32-bit)
As far as I know you can't downgrade a 64-bit installation to a 32-bit one.

Even though my system is Debian running x86_64, I haven't had a problem finding libraries. I ask mostly because I'd like to do the same thing with my Droid. I haven't found a good app to do so yet. VLC is the app on server-side, and vlc stream convert is the Droid-X VLC client. I get server-side errors like [0xd59f50] main stream out error: Failed to create audio filter [0xd59f50] stream_out_transcode stream out error: Failed to find conversion filter for resampling [0xd59f50] stream_out_transcode stream out error: cannot create audio chain [0xdf8a50] main decoder error: cannot create packetizer output (mp4a) when I try streaming from my 64-bit box. If I mount said directories from a 32-bit box, and stream, it all works fine. Depending on the application you use and libraries you require, if you can find the application and the ia32 libraries the app needs, you can certainly run it on a 64-bit system. I've done this before (again, on a Debian system) as you can get the ia32 versions of libraries, extract the libraries from the .deb, and install them by hand. I'd have to look at my notes to see what the rest of the process was, but I remember it was pretty straightforward after that. Hmmm... might be worth looking into. I mean, what's the worst that happens? I bork my system, and wind up doing a re-install. Which is what I'm looking at, anyway. So, yeah -- I'll poke around and see what I can make happen.
