Samsung N150 Plus upgrade from Lubuntu 16.04 LTS to Lubuntu 20.04.1 - performed 17/12/20

Backup and prep process

  • Copied all documents and important files from Samsung laptop to removable hard drive. Used Lubuntu gui file manager which crashed at least twice, probably due to netbook limited RAM.

  • Found out that a direct upgrade from 16.04 LTS to 20.04 LTS is not possible, refer to the following links.

  • Downloaded Lubuntu 20.04.1

  • Found a spare 32GB USB stick and copied all the files that were on it to a removable hard drive.

  • Opened downloaded Lubuntu image using Disk Image writer (1st time I've used this), wrote image to 32GB SD, found process very easy

  • On Samsung netbook hit F2 at boot time to select boot from USB

  • Booted from USB stick containing LUBUNTU 20.04.1

Live distro 1st boot.

  • Once booted I found the trackpad speed to be very slow and my first attempt at adjusting the speed in preferences made no difference.

  • Connected to WiFi, setting this up seemed much more clunky than previous connection method, however it did work.

  • Went to Youtube and played some video, everything worked fine, also found that volume keys on netbook worked.

Install Process

  • Went through install and selected manual partitioning,

  • Used existing swap on sda6 and format and mounted new Lubuntu root filesystem on sda7 replacing 16.04 with 20.04.1

After first boot

  • Upon first boot was surprised that it had remembered my WiFi connection details and told me there were updates

  • It asked if I wanted to perform a full upgrade without giving any details. At the time I didn't know what this meant. I wasn't sure I would remain on an LTS or upgrade to 20.10. After the full upgrade I check OS release using the following command. This confirmed I was still running 20.04 LTS

      cat /etc/os-release
  • The logon screen has desktop options, by default it's set to Lubuntu, I found this to be a bit slow and unresponsive also the screen decoration on terminals was rather clunky taking up unnecessary screen space.

  • The next time I entered the logon screen I selected LXQT. I was pleased to find that this option was remembered. The netbook was now a bit more responsive though not quite as good as it was before the upgrade. The terminal screen was now much tidier and more usable.

  • Preferences / LXQT settings / Keyboard and mouse / Mouse and Touch Pad / Acceleration speed now 5.0 think was 0.1, also selected single click to activate item

  • Installed mc, ncdu, screen, pv, moc, ssh

  • Generated RSA ssh keys and copied them to Pi13, they installed with no problems and allowed me to SSH into my Pi13.

  • Copied all my files and documents from my portable hard drive back onto the laptop. This time I used mc "Midnight Commander" to copy the files back which I found much easier than using the GUI file manager the first time around. Midnight commander is an Ncurses file manager.

  • I had forgotten just how good the ncurses file manager Midnight commander is.

  • Midnight Commander gave a constant percentage progress of each individual file being copied and the overall progress which was very useful and reassuring with such a slow laptop. The first time around the laptop actually crashed a couple of times when I was using the LUBUNTU GUI file manager to try and copy the files from the laptop to the hard drive.

  • Also even though I generally use keyboard shortcuts for copy and paste operation I still tend to use the track pad at places when using a file manager. It's easy to limit yourself to keyboard navigation using mc. I found this to be greatly reassuring and I feel doing this makes the likelihood of disastrous errors much less likely.

General thoughts and Observations

  • The keyboard screen brightness buttons don't work however I can adjust it within preferences. Further investigation will be needed to resolve this minor annoyance if / when I get the time and inclination.

  • The netbook now has a much slower boot time

  • The netbook now feels a little sluggish but I think it's still perfectly usable. I have a feeling this might be the last upgrade this netbook sees as it's now getting a bit long in the tooth. It also has a broken power switch which I believe was a common fault. I have to use a pair of scissors to turn it on.
