Ubuntu 18.04 Tweaks for a 16.04 User
Jun 24th, 2019 by miki

This post will detail some stuff I’ve done to a plain Ubuntu 18.04 Desktop (bionic) to make me feel a little more at home in the transition from my daily driver for years the 16.04 release using Canoncial’s Unity as the primary desktop interface to the GNOME Shell of 18.04. Canonical abandoned the former after shifting focus from the convergence and personal device market to cloud and IoT in 2017 leaving development of its mobile OS, Ubuntu Touch which Unity is a part of, to the community formed UBports project (Unity8 is now known as Lomiri). I’ve been putting off this transition exactly because I knew it would require me to make some tweaks to my daily routines, but this system is not one I use on a daily basis so it will make the transition a gentle ride.

The intention is to update this as the experience progresses.

EDIT 2021-08-25: clean up and publish dormant draft post

Browsing GNOME Extensions

To be able to install GNOME Extensions directly from a browser while perusing the directory at extensions.gnome.org, add the GNOME Shell Integration extension/add-on to your browser (Firefox add-on, Chrome Web Store), then install the Integration extension in GNOME to communicate with the browser extension:

sudo apt install chrome-gnome-shell

After this you can go to extensions.gnome.org/local/ to see, configure and update installed extensions.

Time Keeping

World/Alarm/Stopwatch/Timer application

GNOME includes a nice Clock application which is available in the package repository but not installed by default;

sudo apt install gnome-clocks

Installing the Alarm Clock extension described above, will also show the application’s alarms in the notification area.

Notification bar

I like both the date and seconds to be displayed in the head of the desktop, so to format the text a couple of extensions are available;

Itch: eog core dump on Galaxy 7 panorama image
Jun 10th, 2019 by miki

  • Took some photos with my Galaxy 7. Some were panoramas.
  • EOG crashed while loading them.
  • Memory was low.
  • Maybe related to previously experienced missing EOI marker issue with Samsung camera application.

Will investigate later and amend the post (promise!).
