    After who knows how many hours at least I have her recovery mode back

    While attempting to get 16.04 to boot with the Nvidia driver and correct resolution...the install went into dante's inferno. The road to the inferno started when I tried to install nvidia driver 378. After all -- when I watch the install messages on a 304 install, it also mentions installing something about 378. So I thought --- why not just install 378. Ouch --- BIG problem with that one. I lost the ability to even get a boot with recovery mode.

    From blinking log-on screens where I had to hit the keys to the terminal, input two letters, screen blinks off -- hit keys again - input more letters, accomplished removing or adding Nvidia drivers. Then it reached a point that I couldn't boot into recovery without the blinking. Then there was the Xauth: timeout in locking authority file.xauthority problem. More terminal commands...got to the point that now I could at least get a non-blinking terminal log-on screen, which is much easier to type on and more input. Then I would see my desktop screen but the only thing that would work was the alt F2 key and that would allow me to start apps but the desktop was like a dead fish. Even the clock stopped at the time it booted. More terminal commands and then --- finally I could boot into the correct recovery screen and everything works. Not sure if I want to attempt to boot normally or even boot at all.

    My wife is happy with having her kitchen comp. back and I should leave it at that but there is that nagging bit in my head saying --- "but it isn't working as it should."

    I was going to attempt to re-install the OS saving home and keeping MS7 on the one partition but then I got to the point where it talked about partitioning. I always choose other but I don't do it often enough and didn't know how to proceed and keep all current partitions --- just re-install the OS.

    I kept seeing that at one time Ubuntu has or had an option during install to just reinstall. I don't think I ever saw that option on kubuntu live CD. It would be a nice option. Kind of like inserting Windows disc to repair something gone wrong.

    I'd just like to know what to or how to back up this session that is working.

    It's not clear to me what you're asking. If it's "How to do a new install over a previous install?" you can choose "Manual partitioning", select the correct partition for the root ("/") install and chick the "format" tick-box, select the correct partition for /home but DON'T tick the "format" box and install. This assumes you already have /home on a separate partition. If not, things can get a bit more complicated. You'll have to give more specific details in that case - start with your current partition layout.

      Complete guide using "Manual partitioning" (Something else method) here:

      As oshunlur stated above, click on "Manual" and DON'T FORMAT HOME!.

        I don't have home on a different partition. Wish I would have done that on all our boxes that have an install. Some have had Kubuntu on for years and back then I didn't know about the benefit of placing home on a separate partition.

        I have copied home and if need to I can always move it to a reinstall.

        Right at the moment, how I did it I do not know but the kitchen computer is happy, it boots into the correct resolution and I don't need to use recovery mode to boot into. Sometimes it takes a few tires to get it to boot correctly but it seems that after three tries I get there.

          Well, if you're going to leave it be, fine. Otherwise, here's what I suggest:
          1) Boot to a liveUSB of Gparted or Kubuntu.
          2) Shrink your install partition to free up enough space for home.
          3) Make a new partition for /home.
          4) Move all the folders from /home in the install to the new partition.
          5) Edit /etc/fstab in the install to reflect the new partition and mount it at /home.
          6) Reboot.

          Then you'll have a separate /home partition for when you're ready to re-install. I mentioned Gparted just because it has all the needed partitioning tools on it and they're easy to find. You can do it with Kubuntu if you'd rather.

          Since you have /home backed up there is another, slightly more advanced, possibility: Do a new full install of Kubuntu (or KDEneon even better IMO) and reformat the install partition as btrfs instead of ext4. This will automatically create a separate root and home subvolumes - rather than partitions. Then restore your home files to the new /home. Brief explanation: btrfs uses subvolumes to segregate space within a single file system. This allows all the free space to be available to all the subvolumes rather than having to guess how much space an install will need vs. home. You can also make easy backups by sending a full copy of any subvolume to another btrfs file system or device - either over the network or on a device (thumb drive or 2nd disk) on the computer. btrfs also natively supports snapshots. Which means you can take a snapshot before upgrading or mucking about with video drivers, and then restore it to it's original state if something goes haywire. Thus avoiding the above problem entirely.

            Guessing that tutorial will work with all flavors.

              I used Knoppix to make a copy of home on a flash drive. I don't think I got any of the "can't copy sybonic links" messages using Knoppix. I think there was a mention of a few files that couldn't be copied but looking at what was copied it appears that all files, including hidden files / folders was copied.

              I'm familiar with Partition Wizard and I imagine I could use that to manipulate partitions.

              Is KDE Neon a good choice for older computers?

                Can't say without the specs. "Older" is relative. My 10 year old PC that I just retired ran great with KDEneon, but it was a Quad core Q6600 running at 3GHz, 8GB RAM, GTX 780 video card. An old slow Celeron? maybe not.

                  I've put KDE Neon User Edition on a 7 year old Acer and on mine, a 5 year old Acer with two GPUs, the primary is Intel's and the 2ndry is GT650M, which can NOT be made primary in the bios. Despite that, nvidia-370 made the GT650Mmy primary for everything without having to manually set optirun in the menu or cli. Neon is the best "distro" I've ever used in 19 years with Linux

                    Oh? I need to check it out. "Neon is the best "distro" I've ever used in 19 years with Linux"

                    There is a lot of room on the hard drive for another partition and another install.

                      Not sure how old the box is but it has

                      2X AMD Athlon II X2 220 processor
                      6 gig ram
                      GeForce 6150 SE nForce 430
                      I think the HD is either 300 or 500.

                      Has Win 7 OEM certificate inc.

                        I think that CPU could handle KDEneon and Plasma 5 desktop just fine. Frankly, if it ran windows 7 it'll run on linux better. The extra RAM won't hurt. You could mount tmpfs in RAM to speed things up a bit. As long as you weren't running a dozen programs at once, you wouldn't use swap so that keeps things faster too.

                          It seems that whenever I have a problem on an older computer it is always, always, always a video problem. And 99.9% of the time Nvidia is at the root of the problem.

                          I have the swap set at 25 for a just in case situation but with 6 gigs of ram no swap should be fine.

                            Did an ISO of recent NEO LTS and let it boot --- immediately when the video loaded the screen crashed into a lot of tearing. Started again, went to look for the boot option to start in nomodeset and nothing available. I am accustomed to F6 bringing up the different boot options.

                            So I can't give it a try.

                              F6? Never heard of that one. That a windows thing?

                              If you see a grub menu, hit the "e" key to temporarily (as in: not saved) edit the boot line. Look for "quiet splash" and put nomodset there. If there's no grub menu, hold down the SHIFT key when booting until you see the grub menu, then the e key to edit.
