I am under the impression that I have a video problem due to installing restricted and non-free codecs in the wrong order. My maintenance was done in an orderly fashion for a while but at this point I don't really know what I have. What I believe I want to do is uninstall & reinstall 10.4 I upgraded from 9.10 and have two users. (Yes, I have backups from "home" but) I hope that there is a way to just start over without restores. My search didn't yield anything. Where should I look?

After you backup all your data from both users, i suggest simply do a fresh install.

But as always Backup, Backup.

Part of my question was "how do you do a fresh install"? This install was done with the Update Manager. Is there a way to use that again? The Update Manager understood that the starting point wasn't a blank slate. I don't see how this would work but I've missed things before.

I have a USB flash drive with a working 10.4 on it. If I reinstall from that does it understand that I have two users and files out there? I'm afraid to just try it without knowing what it does in advance.

I keep backups of everything downstream from home. Is that adequate?

My biggest frustration isn't that things go wrong. It is that I can't find the information that I am looking for by myself. I have The Official Ubuntu Book (from 8.04) and that hasn't been and isn't any help. I've tried searching but perhaps my search strings are inadequate.

thanx,,,

Depending how experienced you are with ubuntu, do you know if you have separate /home partition or not?

No, I only have a swap and an ext3 partition. I think I see where you are going. If I re-partition separating /home from the rest what do I have to do so the OS finds the new /home? This sounds like I need to read about mount points. Is that the right topic and are there any other topics I should cover?

If my home is in a separate partition then a new install into the partition where the current OS resides should leave my user data alone. I like it! If I do nothing (not repartition) and reinstall from the flash drive is that supposed to leave my user data alone?

thanx,,,,

I used this to move /home:

Sometimes there are dmrc errors or permission errors and this has how to correct them:

https://help.ubuntu.com/community/Partitioning/Home/Moving

All your user settings are in /home, but if you have system settings they will be in /etc and if you have made a lot of system changes you may lose those settings.
You can also export all the install programs and reinstall them:

You also have to use manual install where you choose the partitions and the formats of the partitions. When choosing /home you DO NOT format that. It finds swap automatically.

Different verisons but all will be similar:

Yes, that's where I was going. I see you got plenty resources from oldfred, so you've got plenty to read now. :)

I'm not one to try it and see what happens. Ideally I'll do my homework and make everything OK on the second try!!

again, thanx,,,,
